WEBVTT 00:00:07.880 --> 00:00:10.759 You're in the bay. Once you get over to the bed, 00:00:10.919 --> 00:00:13.560 we'll give you the story. Everything's going 00:00:13.560 --> 00:00:17.339 to happen super fast. Welcome to the emergency 00:00:17.339 --> 00:00:42.380 room. Pulse check! No pulse. You know, usually 00:00:42.380 --> 00:00:45.280 when you're studying for a nursing exam or you're 00:00:45.280 --> 00:00:47.299 stepping onto a medical surgical floor for a 00:00:47.299 --> 00:00:50.500 clinical rotation, spotting danger is all about 00:00:50.500 --> 00:00:53.460 looking for those blatant universal red flags. 00:00:53.840 --> 00:00:56.000 Right, the stuff they drill into you day one. 00:00:56.159 --> 00:00:58.539 Exactly, like you see a massive spike in a patient's 00:00:58.539 --> 00:01:01.039 white blood cells, you flag it, you see a sudden 00:01:01.039 --> 00:01:03.640 drop in hemoglobin, you call the doctor, but 00:01:03.640 --> 00:01:05.700 then you step into the world of postpartum OB 00:01:05.700 --> 00:01:08.709 nursing and well... suddenly the entire rule 00:01:08.709 --> 00:01:10.890 book is just flipped upside down. It really is 00:01:10.890 --> 00:01:12.629 an upside down world. I mean, what looks like 00:01:12.629 --> 00:01:14.730 an absolute clinical emergency on a standard 00:01:14.730 --> 00:01:17.930 floor is very often just a, well, a completely 00:01:17.930 --> 00:01:20.969 expected, perfectly normal physiological adaptation 00:01:20.969 --> 00:01:23.530 in a postpartum patient. Right. And that gap, 00:01:23.629 --> 00:01:25.950 the difference between what you learned in nursing 00:01:25.950 --> 00:01:28.129 fundamentals and what is actually happening in 00:01:28.129 --> 00:01:31.349 a postpartum body, that is exactly where clinical 00:01:31.349 --> 00:01:33.189 instructors and board exams are going to try 00:01:33.189 --> 00:01:35.709 to trip you up. Which is exactly why we're here 00:01:35.709 --> 00:01:38.890 today. Welcome to this deep dive. Today we are 00:01:38.890 --> 00:01:41.430 basically stepping into the roles of your elite 00:01:41.430 --> 00:01:44.209 OB nursing educators and your clinical mentors. 00:01:44.569 --> 00:01:46.530 Yeah, we've got a huge stack of sources here 00:01:46.530 --> 00:01:48.989 on maternal physiological adaptations and our 00:01:48.989 --> 00:01:51.829 mission is to act as your study coaches. We're 00:01:51.829 --> 00:01:54.890 going to extract the absolute high -yield top 00:01:54.890 --> 00:01:57.609 -tier clinical goal that you need not just to 00:01:57.609 --> 00:02:00.329 crush your nursing school exams but to actually 00:02:00.329 --> 00:02:03.189 walk onto a floor and You know, think like a 00:02:03.189 --> 00:02:05.310 safe, prioritizing nurse. And we are going to 00:02:05.310 --> 00:02:07.510 apply the priority principle aggressively to 00:02:07.510 --> 00:02:09.830 get you there. We're not here to read you a textbook 00:02:09.830 --> 00:02:12.110 page by page. Please, no. Right. We're going 00:02:12.110 --> 00:02:15.509 to focus purely on the 20 % of concepts, the 00:02:15.509 --> 00:02:17.250 patterns, and the critical safety traps that 00:02:17.250 --> 00:02:19.310 are going to yield 80 % of your exam points. 00:02:19.750 --> 00:02:22.210 But to do that, we actually have to completely 00:02:22.210 --> 00:02:25.169 redefine how you think about the postpartum period. 00:02:25.490 --> 00:02:28.000 Right. Because historically, I mean, society 00:02:28.000 --> 00:02:30.360 and even old textbooks treated postpartum like 00:02:30.360 --> 00:02:32.740 it was just a, I don't know, a quick six week 00:02:32.740 --> 00:02:35.180 break to recover from birth. Exactly, but ACOG, 00:02:35.319 --> 00:02:37.479 so the American College of Obstetricians and 00:02:37.479 --> 00:02:40.400 Gynecologists, they explicitly define postpartum 00:02:40.400 --> 00:02:43.340 care as an ongoing dynamic process that lasts 00:02:43.340 --> 00:02:47.539 at least 12 weeks. 12 weeks. Yeah. It is not 00:02:47.539 --> 00:02:51.939 just a brief recovery. There are massive systemic 00:02:51.939 --> 00:02:54.580 shifts happening in the cardiovascular system, 00:02:55.020 --> 00:02:56.939 the endocrine system, and the immune system for 00:02:56.939 --> 00:03:01.460 months. OK, let's unpack this. So if we're prioritizing, 00:03:01.780 --> 00:03:03.360 if we're looking at this through the lens of 00:03:03.360 --> 00:03:05.680 an exam coach trying to keep a patient safe, 00:03:06.479 --> 00:03:09.819 what is the absolute number one threat we have 00:03:09.819 --> 00:03:12.539 to monitor the second that baby is delivered? 00:03:12.819 --> 00:03:15.099 Without a doubt, it is hemorrhage. And to understand 00:03:15.099 --> 00:03:16.979 hemorrhage, you have to understand the interaction 00:03:16.979 --> 00:03:19.479 between the uterus, the bladder, and the lochia. 00:03:19.599 --> 00:03:22.419 The hemorrhage triangle. Exactly. This trio is 00:03:22.419 --> 00:03:24.840 the absolute bedrock of your clinical judgment. 00:03:25.219 --> 00:03:27.379 So let's start with the uterus. Immediately after 00:03:27.379 --> 00:03:30.360 birth, it weighs about 1 ,000 grams. Wow. Yeah, 00:03:30.360 --> 00:03:32.699 it's roughly the size of a grapefruit or like 00:03:32.699 --> 00:03:35.000 a small watermelon. And over the next six weeks, 00:03:35.000 --> 00:03:37.240 it has to undergo a process called involution 00:03:37.240 --> 00:03:39.740 to shrink all the way down to about 100 grams. 00:03:39.879 --> 00:03:42.300 OK, wait. How does an organ just shrink to a 00:03:42.300 --> 00:03:44.439 tenth of its size that quickly? Well, it's a 00:03:44.439 --> 00:03:47.060 fascinating process called autolysis. Autolysis. 00:03:47.379 --> 00:03:50.520 Right. The drop in pregnancy hormones causes 00:03:50.520 --> 00:03:53.280 the protein material of the uterine muscle cells 00:03:53.280 --> 00:03:55.659 to literally break down and just be absorbed 00:03:55.659 --> 00:03:58.319 by the body. Oh. But more importantly, for immediate 00:03:58.319 --> 00:04:01.360 safety, that muscle has to violently contract 00:04:01.360 --> 00:04:04.240 because when the placenta detaches, it leaves 00:04:04.240 --> 00:04:07.300 behind massive open blood vessels. Right, like 00:04:07.300 --> 00:04:10.259 a wound. Exactly like a wound. The only way the 00:04:10.259 --> 00:04:12.979 patient doesn't bleed out is if the uterus clamps 00:04:12.979 --> 00:04:15.819 down incredibly hard to put pressure on those 00:04:15.819 --> 00:04:18.550 vessels. It acts like a biological tourniquet. 00:04:18.629 --> 00:04:20.509 And if it doesn't clamp down, we have a postpartum 00:04:20.509 --> 00:04:23.689 hemorrhage. But how strictly is that defined 00:04:23.689 --> 00:04:26.430 for an exam? Because I know different doctors 00:04:26.430 --> 00:04:28.129 might have different thresholds in practice. 00:04:28.509 --> 00:04:31.930 For your exams, you stick to ACOG's strict definition. 00:04:32.230 --> 00:04:34.430 A postpartum hemorrhage is blood loss greater 00:04:34.430 --> 00:04:37.410 than 1 ,000 milliliters, accompanied by signs 00:04:37.410 --> 00:04:39.569 or symptoms of hypovolemia. Does it matter if 00:04:39.569 --> 00:04:41.389 it was a C -section versus a vaginal delivery? 00:04:41.529 --> 00:04:43.389 Not anymore. It doesn't matter. The threshold 00:04:43.389 --> 00:04:46.449 across the board is 1 ,000 milliliters. OK, so 00:04:46.449 --> 00:04:48.730 if I'm the nurse and I walk into the room 12 00:04:48.730 --> 00:04:51.810 hours after birth to assess this, biological 00:04:51.810 --> 00:04:54.829 tourniquet. What am I hoping to feel? Like what 00:04:54.829 --> 00:04:57.670 is the expected safe finding? You're feeling 00:04:57.670 --> 00:05:00.009 for the fundus, which is the very top part of 00:05:00.009 --> 00:05:02.170 the uterus. You want it to be firm to the touch, 00:05:02.589 --> 00:05:04.889 globular, and right in the midline of the abdomen. 00:05:04.990 --> 00:05:08.230 Midline, OK. Yeah. And at 12 hours postpartum, 00:05:08.230 --> 00:05:11.329 it should be right at or maybe slightly below 00:05:11.329 --> 00:05:14.529 the umbilicus, the belly button. And from there, 00:05:14.750 --> 00:05:16.589 the rule of thumb is that it should decrease 00:05:16.589 --> 00:05:19.509 in size by about one centimeter or one finger 00:05:19.509 --> 00:05:21.970 breadth every single day. OK. So if firm and 00:05:21.970 --> 00:05:24.850 midline is safe, I'm guessing soft is the danger 00:05:24.850 --> 00:05:29.060 zone. Yes. term for that is boggy. Boggy. Right. 00:05:29.339 --> 00:05:31.879 If you press down and it feels like a soft sponge 00:05:31.879 --> 00:05:34.639 instead of a firm grapefruit, that is a boggy 00:05:34.639 --> 00:05:36.459 fundus and it means those vessels are bleeding. 00:05:36.620 --> 00:05:38.740 But here's the scenario that I see students freeze 00:05:38.740 --> 00:05:41.600 up on all the time. You go to assess the fundus 00:05:41.600 --> 00:05:44.399 and it's firm, but it's not midline. Yes, the 00:05:44.399 --> 00:05:47.560 deviation trap. Right. It is shifted way over 00:05:47.560 --> 00:05:49.899 to the side, usually the right side, and it's 00:05:49.899 --> 00:05:52.019 sitting way higher up in the abdomen than it 00:05:52.019 --> 00:05:55.259 should be. Why does it do that? Think about the 00:05:55.259 --> 00:05:58.259 anatomy. What organ sits directly underneath 00:05:58.259 --> 00:06:01.180 the uterus? The bladder. The bladder. During 00:06:01.180 --> 00:06:03.339 labor, the bladder goes through severe trauma, 00:06:03.639 --> 00:06:05.839 and if the patient had an epidural, it becomes 00:06:05.839 --> 00:06:08.819 completely hypotonic. So they can't even feel 00:06:08.819 --> 00:06:11.120 that they need to pee. Exactly. They lose the 00:06:11.120 --> 00:06:13.379 urge entirely, so the bladder just fills and 00:06:13.379 --> 00:06:15.560 fills with urine until it becomes incredibly 00:06:15.560 --> 00:06:17.680 distended. Oh, I see. So if the uterus is trying 00:06:17.680 --> 00:06:20.410 to clamp down like a... like a giant contracting 00:06:20.410 --> 00:06:23.730 balloon, a massively distended bladder is essentially 00:06:23.730 --> 00:06:26.629 acting like a huge rock sitting right underneath 00:06:26.629 --> 00:06:29.629 it. That is the perfect analogy. The bloom can't 00:06:29.629 --> 00:06:31.970 contract properly because this rock is physically 00:06:31.970 --> 00:06:34.129 pushing it up and out of the way. Right, the 00:06:34.129 --> 00:06:36.709 rock is in the way. And if the uterus can't contract 00:06:36.709 --> 00:06:39.230 because it's being displaced, those placental 00:06:39.230 --> 00:06:42.089 vessels open back up and the patient hemorrhages. 00:06:42.389 --> 00:06:45.209 So that instantly dictates our priority nursing 00:06:45.209 --> 00:06:49.129 actions. If I feel a boggy uterus, my immediate 00:06:49.129 --> 00:06:52.509 reflex is to massage it with my hands to force 00:06:52.509 --> 00:06:55.649 the muscle to contract. But if I feel a firm, 00:06:55.930 --> 00:06:58.589 deviated uterus, massaging it isn't the primary 00:06:58.589 --> 00:07:01.490 fix. I need to get rid of the rock. Precisely. 00:07:02.069 --> 00:07:04.750 You must get that client up to empty their bladder 00:07:04.750 --> 00:07:07.839 immediately. As a hard rule for your clinicals, 00:07:07.860 --> 00:07:10.300 that first void needs to happen within six hours 00:07:10.300 --> 00:07:12.680 of birth or within six hours of a catheter being 00:07:12.680 --> 00:07:14.519 removed. And if they can't go on their own? You'll 00:07:14.519 --> 00:07:16.540 have to straight catheterize them. Okay, got 00:07:16.540 --> 00:07:19.680 it. And as they're healing, we're tracking their 00:07:19.680 --> 00:07:22.579 lochia, the vaginal discharge. Is there a cheat 00:07:22.579 --> 00:07:24.579 code to memorizing the timeline for this because 00:07:24.579 --> 00:07:26.180 all the different stages just blend together 00:07:26.180 --> 00:07:28.319 in my head? Absolutely. Write down the rule of 00:07:28.319 --> 00:07:30.240 threes and tens. Threes and tens, okay. First 00:07:30.240 --> 00:07:32.699 is lochia rubra, which is dark red blood, and 00:07:32.699 --> 00:07:35.139 that lasts from days one through three. Next 00:07:35.139 --> 00:07:38.000 is lochia cirrhosa, which turns pinkish -brown 00:07:38.000 --> 00:07:41.220 lasting days 4 through 10. Okay. Finally, lochia 00:07:41.220 --> 00:07:43.100 alba, which is yellowish -white lasting from 00:07:43.100 --> 00:07:45.740 day 10 up to day 14 or sometimes even longer. 00:07:46.040 --> 00:07:48.980 And the ultimate exam trap here. If that dark 00:07:48.980 --> 00:07:52.920 red lochia rubra continues past day 4 or if they're 00:07:52.920 --> 00:07:57.189 soaking a perineal pad in under one hour or passing 00:07:57.189 --> 00:08:00.529 clots larger than a chicken egg, that is a massive 00:08:00.529 --> 00:08:03.430 red flag. A massive red flag. You report it immediately 00:08:03.430 --> 00:08:06.129 because it implies retained placental fragments 00:08:06.129 --> 00:08:09.529 or uterine antony. Exactly. Now let's follow 00:08:09.529 --> 00:08:12.050 the physiological thread here. If that uterus 00:08:12.050 --> 00:08:15.310 is clamping down incredibly hard, what is happening 00:08:15.310 --> 00:08:17.670 to all the blood that was previously circulating 00:08:17.670 --> 00:08:19.449 through it? Well, it's getting forced back into 00:08:19.449 --> 00:08:22.410 the mother's main system, right? Which... I guess 00:08:22.410 --> 00:08:24.529 brings us to hemodynamics and the vital sign 00:08:24.529 --> 00:08:27.410 fakeouts. Because the amount of blood that shifts 00:08:27.410 --> 00:08:31.470 is staggering. It really is. Roughly 500 to 750 00:08:31.470 --> 00:08:33.570 milliliters of blood is suddenly pushed from 00:08:33.570 --> 00:08:35.549 the utero placental unit right back into the 00:08:35.549 --> 00:08:38.049 maternal central circulation. That's a huge volume. 00:08:38.309 --> 00:08:40.029 Plus, the physical weight of the baby is gone, 00:08:40.090 --> 00:08:42.250 so the pressure on the inferior vena cava is 00:08:42.250 --> 00:08:45.120 instantly lifted. Because of this, maternal cardiac 00:08:45.120 --> 00:08:48.519 output spikes by 60 to 80 % immediately after 00:08:48.519 --> 00:08:50.659 birth. That sounds like it would send the body 00:08:50.659 --> 00:08:53.700 into absolute fluid overload. Like, how does 00:08:53.700 --> 00:08:56.539 a body not just drown in its own fluid? It initiates 00:08:56.539 --> 00:09:00.179 a massive purge. The body gets rid of this excess 00:09:00.179 --> 00:09:03.639 fluid through two main routes, severe diuresis 00:09:03.639 --> 00:09:06.500 and diaphoresis. Peeing and sweating. Exactly. 00:09:06.799 --> 00:09:08.960 Your patient might pee up to 3 ,000 milliliters 00:09:08.960 --> 00:09:10.860 a day, and they'll likely wake up completely 00:09:10.860 --> 00:09:13.539 drenched in sweat. It's totally expected. Which 00:09:13.539 --> 00:09:16.159 perfectly sets up the exam traps that instructors 00:09:16.159 --> 00:09:18.899 just love, because these massive shifts make 00:09:18.899 --> 00:09:21.399 the lab results look terrifying to an untrained 00:09:21.399 --> 00:09:24.179 eye. Oh yeah. Let's talk about the infection 00:09:24.179 --> 00:09:26.139 fake out. If I'm looking at a chart and I see 00:09:26.139 --> 00:09:29.679 a white blood cell count of 25 ,000, my instinct 00:09:29.679 --> 00:09:32.470 is to panic. On any other floor, I'm calling 00:09:32.470 --> 00:09:35.129 a rapid response and hanging broad spectrum IV 00:09:35.129 --> 00:09:37.830 antibiotics. But in postpartum, you just document 00:09:37.830 --> 00:09:40.769 it as normal. Think about the why. OK, why? The 00:09:40.769 --> 00:09:43.230 physical exertion, the tissue trauma, and the 00:09:43.230 --> 00:09:45.610 extreme stress of labor naturally trigger a massive 00:09:45.610 --> 00:09:48.210 inflammatory response. The white blood cells 00:09:48.210 --> 00:09:51.049 spike up to 25 ,000 simply from the stress of 00:09:51.049 --> 00:09:53.809 giving birth. Wow. So how do I actually know 00:09:53.809 --> 00:09:56.779 if they have a real infection? You never chase 00:09:56.779 --> 00:09:59.000 an infection based on white blood cells alone 00:09:59.000 --> 00:10:01.759 in the first few days. You only act if that elevated 00:10:01.759 --> 00:10:04.419 count is paired with a maternal fever over 38 00:10:04.419 --> 00:10:08.200 degrees Celsius, which is 100 .4 degrees Fahrenheit, 00:10:08.720 --> 00:10:11.779 or if you assess foul -smelling lochia. Otherwise, 00:10:11.899 --> 00:10:14.299 it's just the body's stress response. Exactly. 00:10:14.419 --> 00:10:17.039 That is such a good trap to know. So the second 00:10:17.039 --> 00:10:20.639 one is the hemoglobin fakeout. We just established 00:10:20.639 --> 00:10:22.639 that they're at risk for hemorrhage, so naturally, 00:10:22.960 --> 00:10:25.409 students want to check. the hemoglobin and hematocrit 00:10:25.409 --> 00:10:27.590 to see how much blood the patient lost. And if 00:10:27.590 --> 00:10:30.029 they do that in the first 24 hours, they're going 00:10:30.029 --> 00:10:32.210 to get completely inaccurate data. Because of 00:10:32.210 --> 00:10:34.149 the fluid shifts. Right. Because of all that 00:10:34.149 --> 00:10:36.269 extracellular fluid shifting into the vascular 00:10:36.269 --> 00:10:39.850 system, the blood becomes hemodiluted. Oh, right. 00:10:39.870 --> 00:10:41.629 It's like having a glass of juice and pouring 00:10:41.629 --> 00:10:44.649 an extra cup of water into it. The absolute amount 00:10:44.649 --> 00:10:47.070 of sugar in the glass hasn't changed, but the 00:10:47.070 --> 00:10:49.149 concentration looks way lower because there's 00:10:49.149 --> 00:10:51.289 so much extra liquid. That's a great way to think 00:10:51.289 --> 00:10:54.039 of it. The labs will look artificially low at 00:10:54.039 --> 00:10:55.960 first because the blood is watered down. You 00:10:55.960 --> 00:10:58.179 have to wait for the body to diurese that fluid 00:10:58.179 --> 00:11:00.820 before you get a true baseline. But the most 00:11:00.820 --> 00:11:04.379 dangerous hemodynamic trap by far is the clot 00:11:04.379 --> 00:11:07.679 risk. Let's unpack this because it feels super 00:11:07.679 --> 00:11:10.299 contradictory. I mean, we spend the first hour 00:11:10.299 --> 00:11:12.399 terrified the patient's going to bleed to death. 00:11:12.899 --> 00:11:16.440 But simultaneously, they are at an enormous risk 00:11:16.440 --> 00:11:19.919 for developing a deep vein thrombosis, a DVT. 00:11:19.919 --> 00:11:22.440 Why? It's an evolutionary defense mechanism. 00:11:22.759 --> 00:11:24.679 To stop the mother from bleeding out when the 00:11:24.679 --> 00:11:27.940 placenta detaches, her clotting factors and fibrinogen 00:11:27.940 --> 00:11:31.139 levels remain highly elevated. OK. Normal fibrinogen 00:11:31.139 --> 00:11:34.039 is about 200 to 400 milligrams per deciliter. 00:11:34.360 --> 00:11:36.679 But postpartum, it stays significantly higher 00:11:36.679 --> 00:11:40.039 for weeks. Evolution prioritizes stopping the 00:11:40.039 --> 00:11:42.799 hemorrhage, but the trade -off is hypercoagulability. 00:11:43.039 --> 00:11:44.720 So we have a patient whose blood is primed to 00:11:44.720 --> 00:11:47.059 clot, who is likely spending a lot of time resting 00:11:47.059 --> 00:11:49.519 in bed, and who might have some vascular damage 00:11:49.519 --> 00:11:51.399 from pushing. I mean, that is the perfect storm 00:11:51.399 --> 00:11:54.080 for a DVT. Which means your priority nursing 00:11:54.080 --> 00:11:57.340 action is to aggressively assess the lower extremities. 00:11:57.600 --> 00:11:59.820 You're looking for unilateral swelling, localized 00:11:59.820 --> 00:12:02.019 warmth, or calf pain. And getting them moving, 00:12:02.120 --> 00:12:04.299 I assume. Yes, getting them out of bed and walking 00:12:04.299 --> 00:12:06.820 as soon as it's physically safe to do so. Early 00:12:06.820 --> 00:12:10.480 ambulation is non -negotiable. So if we synthesize 00:12:10.480 --> 00:12:12.620 all this into how we read their vital signs, 00:12:13.299 --> 00:12:16.659 mild, Friday cardio -like, a heart rate of maybe 00:12:16.659 --> 00:12:19.700 50 to 90 beats per minute is actually an expected 00:12:19.700 --> 00:12:23.139 reassuring finding. It tells us the body is relaxed 00:12:23.139 --> 00:12:25.379 and handling the extra fluid volume efficiently. 00:12:25.879 --> 00:12:29.120 But what if the heart rate is racing? Tachycardia 00:12:29.120 --> 00:12:31.379 is your ultimate red flag. Erasing heart rate 00:12:31.379 --> 00:12:34.259 is almost always your very first vital sign clue 00:12:34.259 --> 00:12:36.440 that the patient is either actively hemorrhaging 00:12:36.440 --> 00:12:39.159 and compensating for blood loss or developing 00:12:39.159 --> 00:12:41.580 a systemic infection. So it happens before the 00:12:41.580 --> 00:12:44.179 blood pressure even drops? Yes. If you see tachycardia, 00:12:44.220 --> 00:12:46.500 you do not wait. You immediately pull back the 00:12:46.500 --> 00:12:48.320 sheets and do a fundal check to ensure they aren't 00:12:48.320 --> 00:12:51.080 bleeding out. Okay, so we've managed the bleeding 00:12:51.080 --> 00:12:53.559 and we know how to read the vitals without getting 00:12:53.559 --> 00:12:56.159 faked out by the fluid shifts. But we aren't 00:12:56.159 --> 00:12:58.950 just monitoring them. We have active interventions 00:12:58.950 --> 00:13:02.129 to do before they're discharged. Let's look at 00:13:02.129 --> 00:13:04.769 the must -know pharmacology and immunizations. 00:13:04.970 --> 00:13:07.690 Let's do it. What are the top priorities to protect 00:13:07.690 --> 00:13:10.149 them and the baby once they leave the hospital? 00:13:10.450 --> 00:13:13.309 The absolute biggest priority on your exam for 00:13:13.309 --> 00:13:16.029 pharmacology will be RH immune globulin, which 00:13:16.029 --> 00:13:19.049 everyone knows as ROGEM. This medication must 00:13:19.049 --> 00:13:21.789 be administered within 72 hours of birth. OK, 00:13:22.049 --> 00:13:24.529 72 hours. But here is the specific scenario. 00:13:24.909 --> 00:13:28.330 It is only given if the mother has an Rh negative 00:13:28.330 --> 00:13:31.190 blood type and her newborn has an Rh positive 00:13:31.190 --> 00:13:34.070 blood type. Why is that specific combination 00:13:34.070 --> 00:13:36.830 so dangerous? Like what is the actual mechanism 00:13:36.830 --> 00:13:39.820 happening in the blood? Well, if fetal Rh positive 00:13:39.820 --> 00:13:42.720 blood mixes with maternal Rh negative blood during 00:13:42.720 --> 00:13:45.659 delivery, the mother's immune system recognizes 00:13:45.659 --> 00:13:48.559 that positive factor as a foreign pathogen. Oh, 00:13:48.559 --> 00:13:51.080 so it attacks it. Right. It starts creating antibodies 00:13:51.080 --> 00:13:52.879 to attack it. Now, that doesn't really affect 00:13:52.879 --> 00:13:54.899 the baby that was just born, but it creates a 00:13:54.899 --> 00:13:57.840 massive danger for the future. How so? If she 00:13:57.840 --> 00:13:59.940 gets pregnant again with another Rh positive 00:13:59.940 --> 00:14:02.840 baby, those antibodies will cross the placenta 00:14:02.840 --> 00:14:05.440 and attack the new fetus's red blood cells, causing 00:14:05.440 --> 00:14:09.179 severe anemia or even fetal death. Wow. So giving 00:14:09.179 --> 00:14:12.100 Rogum within that 72 -hour window essentially 00:14:12.100 --> 00:14:14.879 hides the fetal blood cells from the mother's 00:14:14.879 --> 00:14:17.360 immune system so she never builds those deadly 00:14:17.360 --> 00:14:20.279 antibodies. It is literally protecting her future 00:14:20.279 --> 00:14:23.039 children. Exactly. It's preventative. Next up 00:14:23.039 --> 00:14:26.440 are the vicines. We give the Tdap vaccine to 00:14:26.440 --> 00:14:28.980 the mother and ideally any close family members 00:14:28.980 --> 00:14:31.860 to protect the newborn from pertussis or whooping 00:14:31.860 --> 00:14:33.620 cough. Because the baby can't get it yet. Right. 00:14:33.740 --> 00:14:35.960 The newborn's immune system is incredibly fragile 00:14:35.960 --> 00:14:38.080 and they can't get their own shot until they're 00:14:38.080 --> 00:14:40.879 two months old. So we create a cocoon of immunity 00:14:40.879 --> 00:14:43.240 around them. But what about vaccines like the 00:14:43.240 --> 00:14:46.019 MMR for rubella or the varicella vaccine for 00:14:46.019 --> 00:14:47.899 chickenpox? Because I remember learning that 00:14:48.159 --> 00:14:50.500 Those are strictly forbidden during pregnancy. 00:14:50.720 --> 00:14:52.740 They are forbidden during pregnancy because they 00:14:52.740 --> 00:14:55.379 are live virus vaccines. Giving a live virus 00:14:55.379 --> 00:14:58.279 to a pregnant patient poses a massive risk of 00:14:58.279 --> 00:15:00.539 the virus crossing the placenta and infecting 00:15:00.539 --> 00:15:03.960 the fetus. Right. But postpartum, the fetus is 00:15:03.960 --> 00:15:07.019 out. If we test the mother and find she is non 00:15:07.019 --> 00:15:09.940 -immune to rubella or varicella, she absolutely 00:15:09.940 --> 00:15:13.019 must receive those vaccines before she is discharged. 00:15:13.440 --> 00:15:15.539 But there has to be a catch, right? Because it's 00:15:15.539 --> 00:15:18.080 still a live virus in her system. The catch is 00:15:18.080 --> 00:15:20.700 all about patient education. Because that live 00:15:20.700 --> 00:15:24.100 virus is now in her body building immunity, you 00:15:24.100 --> 00:15:26.019 must strictly instruct her to avoid becoming 00:15:26.019 --> 00:15:28.759 pregnant for at least 28 days after receiving 00:15:28.759 --> 00:15:31.240 the shot. Because if she gets pregnant within 00:15:31.240 --> 00:15:34.500 that window, the new fetus is at risk. Got it. 00:15:34.899 --> 00:15:36.659 OK, let's pivot slightly to pain management. 00:15:36.830 --> 00:15:39.769 because comfort is a huge part of recovery. And 00:15:39.769 --> 00:15:41.750 there are some specific clinical traps here too. 00:15:42.230 --> 00:15:44.570 What's the protocol? We use a step -wise approach. 00:15:44.889 --> 00:15:47.470 You always start with NSAids, like ibuprofen. 00:15:47.549 --> 00:15:49.389 Just standard over -the -counter stuff. Yes. 00:15:49.610 --> 00:15:51.470 But it's not just about generalized pain relief. 00:15:51.750 --> 00:15:54.210 Ibuprofen specifically inhibits prostaglandins, 00:15:54.389 --> 00:15:57.029 which drastically reduces the localized inflammation 00:15:57.029 --> 00:15:59.309 in the perineum and the uterus. You pair that 00:15:59.309 --> 00:16:01.730 with acetaminophen. And if the pain is more severe, 00:16:01.809 --> 00:16:04.669 say from a C -section or a severe tear, and we 00:16:04.669 --> 00:16:06.809 need to move up to an opioid -like oxycodone. 00:16:06.970 --> 00:16:10.009 This is a major safety check. Before you ever 00:16:10.009 --> 00:16:12.629 administer an opioid, you must review the patient's 00:16:12.629 --> 00:16:15.090 chart and assess for any history of substance 00:16:15.090 --> 00:16:18.190 abuse or opioid unction. That makes total sense. 00:16:18.509 --> 00:16:20.809 Offering a narcotic to a patient who has fought 00:16:20.809 --> 00:16:23.629 for recovery can cause devastating long -term 00:16:23.629 --> 00:16:27.029 harm. You must advocate for alternative pain 00:16:27.029 --> 00:16:29.450 management strategies if that history is present. 00:16:29.649 --> 00:16:32.269 And we have so many local alternatives too, like 00:16:32.269 --> 00:16:35.029 we use topical anesthetic sprays like benzocaine, 00:16:35.210 --> 00:16:37.950 which patients know as dermoplast, to numb the 00:16:37.950 --> 00:16:40.169 perineum. Yes, those are great. We also teach 00:16:40.169 --> 00:16:42.330 them how to use a sitz path keeping the water 00:16:42.330 --> 00:16:45.789 warm around 94 to 98 degrees to promote blood 00:16:45.789 --> 00:16:49.100 flow and healing. or if the goal is to numb the 00:16:49.100 --> 00:16:51.759 area and reduce immediate swelling using cooler 00:16:51.759 --> 00:16:54.340 water or ice packs for 10 to 20 minutes at a 00:16:54.340 --> 00:16:56.240 time. While we're talking about comfort, we have 00:16:56.240 --> 00:16:58.759 to talk about the GI tract. You must aggressively 00:16:58.759 --> 00:17:01.059 manage constipation. Why is it always such a 00:17:01.059 --> 00:17:03.580 big issue postpartum? Is it just the fear of 00:17:03.580 --> 00:17:05.839 pushing? Fear is a huge part of it, especially 00:17:05.839 --> 00:17:08.220 if they had perineal tearing or hemorrhoids. 00:17:08.599 --> 00:17:11.150 But it's also physiological. During pregnancy, 00:17:11.549 --> 00:17:14.130 elevated progesterone levels significantly slow 00:17:14.130 --> 00:17:16.470 down intestinal peristalsis. Oh, right. Everything 00:17:16.470 --> 00:17:18.710 slows down. Add in the dehydration from labor 00:17:18.710 --> 00:17:20.630 and potentially the side effects of those opioids 00:17:20.630 --> 00:17:22.970 we just mentioned, and you have a recipe for 00:17:22.970 --> 00:17:26.710 severe constipation. So docuset sodium is basically 00:17:26.710 --> 00:17:29.650 our best friend here. It's a surfactant laxative, 00:17:29.650 --> 00:17:32.490 so it pulls water and fat into the stool to soften 00:17:32.490 --> 00:17:35.549 it, making it much less painful to pass. Absolutely. 00:17:35.690 --> 00:17:37.890 Do not let them leave without a stool softener. 00:17:38.130 --> 00:17:39.849 All right. So we've secured the physical safety. 00:17:40.039 --> 00:17:42.500 We've managed the bleeding, monitored the vitals, 00:17:42.920 --> 00:17:44.859 administered the meds, and handled the pain. 00:17:45.380 --> 00:17:48.599 But as a clinical mentor, where do you see the 00:17:48.599 --> 00:17:51.140 most long -term risk for these patients? The 00:17:51.140 --> 00:17:53.640 highest risk for long -term complications often 00:17:53.640 --> 00:17:56.339 lies in what we cannot physically see on a monitor. 00:17:56.849 --> 00:18:00.049 The endocrine crash and the psychosocial transition. 00:18:00.250 --> 00:18:02.470 The endocrine crash. Yeah. When the placenta 00:18:02.470 --> 00:18:04.289 is delivered, it's not just a sack of tissue. 00:18:04.410 --> 00:18:07.650 It was a massive endocrine organ. Once it's gone, 00:18:08.029 --> 00:18:10.009 estrogen and regestion levels plummet rapidly. 00:18:10.369 --> 00:18:12.690 And that hormone crash is what signals the body 00:18:12.690 --> 00:18:15.309 to start making milk, right? Yes. The sudden 00:18:15.309 --> 00:18:18.029 drop in estrogen and progesterone tells the anterior 00:18:18.029 --> 00:18:20.769 pituitary gland to start producing prolactin 00:18:20.769 --> 00:18:23.210 in massive amounts, which triggers lactation. 00:18:23.809 --> 00:18:27.509 And at the exact same time, human chorionic gonadotropin, 00:18:27.589 --> 00:18:31.069 or HCG, plummets to zero within the first week. 00:18:31.250 --> 00:18:34.589 And what about oxytocin? Because we give synthetic 00:18:34.589 --> 00:18:37.609 oxytocin and p -tocin to induce labor, but the 00:18:37.609 --> 00:18:39.349 body makes it naturally during breastfeeding, 00:18:39.569 --> 00:18:43.079 too. Oxytocin is a brilliant dual -action hormone. 00:18:43.619 --> 00:18:46.279 When the baby suckles, oxytocin is released. 00:18:46.700 --> 00:18:49.200 Its first job is the milk ejection reflex, the 00:18:49.200 --> 00:18:51.680 letdown of milk. And the second? Its second job 00:18:51.680 --> 00:18:54.019 is to make smooth muscle contract, which means 00:18:54.019 --> 00:18:56.220 it causes the uterus to cramp down to prevent 00:18:56.220 --> 00:18:58.839 hemorrhage. Which perfectly explains why patients, 00:18:59.200 --> 00:19:01.339 especially, you know, multiparous clients who 00:19:01.339 --> 00:19:03.140 have had multiple babies and have a slightly 00:19:03.140 --> 00:19:05.819 more relaxed uterus, complain of severe abdominal 00:19:05.819 --> 00:19:08.240 cramping while they're nursing. The same hormone 00:19:08.240 --> 00:19:10.609 feeding the baby is actively squeezing the uterus. 00:19:11.009 --> 00:19:13.349 Exactly. And speaking of feeding, you will be 00:19:13.349 --> 00:19:15.769 tested on expected versus concerning findings 00:19:15.769 --> 00:19:18.430 for the breasts. OK, lay it on me. For a breastfeeding 00:19:18.430 --> 00:19:21.589 client, an expected proper latch means the newborn's 00:19:21.589 --> 00:19:24.329 mouth is wide open, covering most of the areola, 00:19:24.569 --> 00:19:27.210 not just the nipple tip. The baby's chin should 00:19:27.210 --> 00:19:29.609 be buried deeply into the breast tissue. And 00:19:29.609 --> 00:19:31.990 it shouldn't hurt. A lot of new parents think 00:19:31.990 --> 00:19:34.650 agonizing pain is normal. It is not. If there 00:19:34.650 --> 00:19:36.650 is pain, the latch is incorrect. And that is 00:19:36.650 --> 00:19:39.480 concerning. And the priority nursing action is 00:19:39.480 --> 00:19:41.839 not to just pull the baby off, which causes more 00:19:41.839 --> 00:19:44.019 damage. What do you do instead? You instruct 00:19:44.019 --> 00:19:46.660 the mother to gently break the suction by inserting 00:19:46.660 --> 00:19:49.079 her finger into the corner of the baby's mouth, 00:19:49.500 --> 00:19:52.119 and then try again. And what if the patient is 00:19:52.119 --> 00:19:55.359 choosing not to lactate? Or... unfortunately 00:19:55.359 --> 00:19:57.619 experienced a loss. How do we care for them? 00:19:57.819 --> 00:20:00.200 You instruct them to avoid all nipple stimulation 00:20:00.200 --> 00:20:02.960 whatsoever. They shouldn't let warm shower water 00:20:02.960 --> 00:20:05.140 hit their chest directly. They need to wear a 00:20:05.140 --> 00:20:08.460 tight, supportive bra continuously, 24 -7, and 00:20:08.460 --> 00:20:11.380 use cold cabbage leaves or ice packs inside the 00:20:11.380 --> 00:20:13.880 bra to naturally suppress milk production and 00:20:13.880 --> 00:20:16.279 relieve engorgement. That brings us to our final 00:20:16.279 --> 00:20:20.160 priority area, psychosocial safety. I notice 00:20:20.160 --> 00:20:22.839 in the sources, there's a huge emphasis on this 00:20:22.839 --> 00:20:25.099 concept of cultural humility versus cultural 00:20:25.099 --> 00:20:28.180 safety. Why is this so highly testable right 00:20:28.180 --> 00:20:31.230 now? Because modern nursing recognizes that you 00:20:31.230 --> 00:20:33.670 cannot possibly memorize every single cultural 00:20:33.670 --> 00:20:36.289 practice regarding diet, rest, or infant care. 00:20:36.369 --> 00:20:38.970 It's just too much. Right. Cultural safety is 00:20:38.970 --> 00:20:41.490 the goal, ensuring the patient feels their identity 00:20:41.490 --> 00:20:44.450 is respected. But cultural humility is the process. 00:20:44.630 --> 00:20:46.690 It means stepping into the room, acknowledging 00:20:46.690 --> 00:20:49.029 your own biases, admitting you don't know everything, 00:20:49.250 --> 00:20:51.690 and asking the client directly, what practices 00:20:51.690 --> 00:20:53.430 are important to your recovery and how can I 00:20:53.430 --> 00:20:55.750 support them? It's shifting from being the absolute 00:20:55.750 --> 00:20:58.549 authority to being a curious partner and their 00:20:58.549 --> 00:21:01.869 care. I love that. Another psychosocial intervention 00:21:01.869 --> 00:21:04.690 the sources heavily emphasize is rooming in. 00:21:04.839 --> 00:21:06.920 keeping the baby in the room with the parents 00:21:06.920 --> 00:21:09.059 instead of sending them to a nursery. The World 00:21:09.059 --> 00:21:11.619 Health Organization pushes rooming in aggressively 00:21:11.619 --> 00:21:14.759 for several evidence -based reasons. It regulates 00:21:14.759 --> 00:21:16.680 the newborn's body temperature much better than 00:21:16.680 --> 00:21:19.420 a plastic bassinet. Yeah, and it exposes the 00:21:19.420 --> 00:21:22.500 infant's skin to normal maternal flora, which 00:21:22.500 --> 00:21:25.759 protects them from hospital pathogens. And crucially, 00:21:25.940 --> 00:21:28.339 it builds parental confidence and significantly 00:21:28.339 --> 00:21:31.000 decreases the risk of maternal postpartum depression. 00:21:31.240 --> 00:21:33.319 Wow. Okay, we have covered an immense amount 00:21:33.319 --> 00:21:35.740 of physiology, pharmacology, and clinical judgment 00:21:35.740 --> 00:21:38.819 today. It is time for our study coach wrap -up. 00:21:38.940 --> 00:21:41.000 Let's do it. If our listener is walking into 00:21:41.000 --> 00:21:44.980 their OB exam tomorrow, what are the five absolute 00:21:44.980 --> 00:21:47.339 golden rules they need to remember to pass the 00:21:47.339 --> 00:21:49.660 test and keep their patients safe? Number one, 00:21:50.099 --> 00:21:53.299 the fundus rules everything. If you feel a soft, 00:21:53.480 --> 00:21:56.519 boggy uterus, massage it immediately. If it is 00:21:56.519 --> 00:21:58.839 firm but deviated to the side, the bladder is 00:21:58.839 --> 00:22:01.500 full and you must get the patient to void. Number 00:22:01.500 --> 00:22:04.180 two, know the strict cutoff for hemorrhage. It 00:22:04.180 --> 00:22:06.579 is anything greater than 1 ,000 milliliters of 00:22:06.579 --> 00:22:09.299 blood loss. And remember, before the blood pressure 00:22:09.299 --> 00:22:12.299 drops, tachycardia is your earliest vital sign 00:22:12.299 --> 00:22:14.299 clue that the patient is bleeding or developing 00:22:14.299 --> 00:22:16.779 an infection. Number three, do not get tricked 00:22:16.779 --> 00:22:19.039 by the vital sign fake -outs. White blood cells 00:22:19.039 --> 00:22:21.920 up to 25 ,000 are completely normal postpartum 00:22:21.920 --> 00:22:24.980 due to the stress of labor. Do not chase an infection 00:22:24.980 --> 00:22:28.099 unless there is a fever over 100 .4 degrees Fahrenheit 00:22:28.099 --> 00:22:32.329 or the lochia smells foul. Number four, the vaccine 00:22:32.329 --> 00:22:36.190 rules. Rh negative mothers with Rh positive babies 00:22:36.190 --> 00:22:40.130 must get Rogan within 72 hours. And nonimmune 00:22:40.130 --> 00:22:42.930 mothers must get their live rubella and varicella 00:22:42.930 --> 00:22:45.809 vaccines before discharge. But they must be taught 00:22:45.809 --> 00:22:49.029 to avoid pregnancy for at least 28 days. Number 00:22:49.029 --> 00:22:52.930 five, pain and GI management. always always assess 00:22:52.930 --> 00:22:55.190 for an opioid history before giving narcotics 00:22:55.190 --> 00:22:57.750 and manage their constipation aggressively with 00:22:57.750 --> 00:23:00.690 a surfactant stool softener like docusate sodium 00:23:00.690 --> 00:23:02.650 so they aren't terrified to use the bathroom. 00:23:03.230 --> 00:23:05.809 That is the high yield gold. But before we finish, 00:23:05.829 --> 00:23:07.789 we want to leave you with one final slightly 00:23:07.789 --> 00:23:10.470 provocative thought to mull over. As nurses, 00:23:10.490 --> 00:23:12.890 we spend so much time focused on the acute clinical 00:23:12.890 --> 00:23:15.789 phase, the hemorrhage, the vital signs, the first 00:23:15.789 --> 00:23:18.309 48 hours of survival. But if you look closely 00:23:18.309 --> 00:23:20.089 at the endocrine data in these sources, it tells 00:23:20.089 --> 00:23:23.240 a much longer story. It truly does. The data 00:23:23.240 --> 00:23:25.380 shows that maternal thyroid function takes a 00:23:25.380 --> 00:23:27.619 full three months to return to its baseline. 00:23:27.740 --> 00:23:30.319 Three months. And hair loss, which happens because 00:23:30.319 --> 00:23:32.779 the pregnancy hormone cycles reverse, doesn't 00:23:32.779 --> 00:23:35.299 even peak until three to six months postpartum. 00:23:35.900 --> 00:23:38.460 The body's insulin sensitization and the stability 00:23:38.460 --> 00:23:41.460 of the pelvic joints can take weeks or even months 00:23:41.460 --> 00:23:44.599 to fully recover. It makes you wonder if maternal 00:23:44.599 --> 00:23:47.559 physiology takes up to a full year to truly reset 00:23:47.559 --> 00:23:50.799 and heal. Why does modern society expect parents 00:23:50.799 --> 00:23:53.059 to be fully adapted and back to work within just 00:23:53.059 --> 00:23:55.759 six to eight weeks? It really highlights a profound 00:23:55.759 --> 00:23:58.519 disconnect between human biology and societal 00:23:58.519 --> 00:24:01.250 expectations. As you step out of nursing school 00:24:01.250 --> 00:24:03.349 and into your future career, you aren't just 00:24:03.349 --> 00:24:05.750 going to be passing exams. You are going to be 00:24:05.750 --> 00:24:08.069 the one standing at the bedside, witnessing this 00:24:08.069 --> 00:24:11.829 biological reality firsthand. Exactly. You started 00:24:11.829 --> 00:24:14.369 this deep dive looking for the clear -cut, black 00:24:14.369 --> 00:24:16.789 -and -white answers to pass the test. But now 00:24:16.789 --> 00:24:19.690 you know the why and the how behind the murky, 00:24:20.069 --> 00:24:22.450 incredibly complex waters of postpartum physiology. 00:24:23.230 --> 00:24:25.549 Keep that perspective the next time you assess 00:24:25.549 --> 00:24:28.299 a postpartum patient. They aren't just recovering 00:24:28.299 --> 00:24:30.799 from a procedure, they are entirely rebuilding 00:24:30.799 --> 00:24:32.880 their physiology. Let that linger as you hit 00:24:32.880 --> 00:24:34.759 the books tonight. You're going to make an incredible 00:24:34.759 --> 00:24:35.059 nurse.
