Postpartum Hemorrhage: Recognize Early, Act Fast

Maternal & Newborn · Postpartum·Updated 2026-10-28

What it is

Postpartum hemorrhage is a cumulative blood loss of 1,000 mL or more, or blood loss with signs of hypovolemia, within 24 hours of birth by any route. After the placenta separates, the myometrium contracts and compresses the open spiral arteries; a boggy, atonic uterus cannot do this, so uterine atony causes most cases. The other causes follow the 4 Ts: tone, trauma (lacerations, hematoma), tissue (retained placenta) and thrombin (coagulopathy).

What the NCLEX focuses on

Atony risk factors: overdistended uterus (macrosomia, twins, polyhydramnios), prolonged or rapid labor, oxytocin augmentation, magnesium sulfate, chorioamnionitis and a full bladder.
A boggy fundus with heavy bleeding means atony; a firm fundus with a steady trickle of bright red blood means a laceration.
A fundus above the umbilicus and deviated to one side means a full bladder, which keeps the uterus from contracting.
Severe perineal or rectal pain and pressure with a rising pulse and a firm fundus suggests a hematoma.
Tachycardia comes first; blood pressure falls late because pregnancy expands blood volume.
Uterotonics: oxytocin first (IV infusion or IM), methylergonovine (avoid in hypertension), carboprost (avoid in asthma), misoprostol; tranexamic acid is added within 3 hours of birth.
Late hemorrhage (24 hours to 12 weeks) comes from subinvolution, retained fragments or infection.

Priority nursing actions

Assess the fundus with the lochia; for a high, deviated fundus, help the client void or perform a straight catheterization.
Massage a boggy fundus firmly while the other hand supports the lower uterine segment above the symphysis.
Call for help, keep or start a large-bore IV line, and give the prescribed oxytocin.
Monitor vital signs, fundus and lochia every 15 minutes and quantify blood loss by weighing pads.
Give second-line uterotonics and tranexamic acid as prescribed after checking contraindications; send type and crossmatch and prepare blood products.

Numbers to know

Value	Threshold	Why it matters
Postpartum hemorrhage	1,000 mL or more, or any loss with hypovolemia, within 24 hours	Current definition for vaginal and cesarean birth
Fundus after birth	Firm, midline, at the umbilicus; descends about 1 cm a day	High or boggy means atony or a full bladder
Pad saturation	One pad in 15 minutes or less	Excessive bleeding; act and report
Quantified blood loss	1 g of pad weight = 1 mL of blood	More accurate than visual estimates
Methylergonovine	0.2 mg IM; hold for blood pressure 140/90 mm Hg or higher	Vasoconstriction causes severe hypertension
Carboprost	250 mcg IM	Bronchospasm in clients with asthma
Tranexamic acid	1 g IV over 10 minutes, within 3 hours of birth	Benefit is lost after 3 hours

Common exam traps

Choosing methylergonovine for a client with preeclampsia or hypertension: wrong because it raises blood pressure and risks stroke.
Choosing carboprost for a client with asthma: wrong because it causes bronchospasm.
Choosing oxytocin by undiluted rapid IV push: wrong because it causes hypotension and dysrhythmias; give it as an infusion or IM.
Choosing more fundal massage for bright red bleeding with a firm uterus: wrong because the source is trauma; report it for repair.
Choosing Trendelenburg position for hypotension: wrong because it impairs ventilation; keep the client flat with the legs raised.

What to teach

Report soaking a pad in 1 hour, clots larger than an egg, foul-smelling lochia, fever of 100.4 F (38 C) or higher, or bright red bleeding returning after lochia turned pink.
Lochia progresses from rubra (days 1 to 3) to serosa (days 4 to 10) to alba; it should not go back to red.
Void every 2 to 3 hours; breastfeeding releases oxytocin and helps the uterus contract.
Rise slowly and take prescribed iron after a large blood loss.

Question 1 · QID 395AD065

Eight hours after a vaginal birth, the nurse finds the client's fundus 2 cm above the umbilicus, deviated to the right, and slightly boggy. Lochia is moderate rubra. Which action should the nurse take first?

Select the best answer.

A. Massage the fundus firmly until it becomes contracted and returns to the midline before addressing the displaced bladder
B. Administer the prescribed intramuscular methylergonovine immediately to improve uterine tone and then reassess fundal position
C. Notify the provider that early postpartum hemorrhage may be developing and prepare prescribed uterotonic medication
D. Assist the client to empty her bladder

Question 2 · QID 3D0AE4C9

The nurse reviews uterotonic prescriptions for several clients with postpartum uterine atony. Which prescriptions should the nurse question? Select all that apply.

A. Oxytocin 20 units in 1,000 mL of lactated Ringer solution by infusion pump
B. Misoprostol 800 mcg rectally
C. Tranexamic acid 1 g intravenously 2 hours after birth
D. Oxytocin 10 units by rapid undiluted intravenous push
E. Carboprost 250 mcg intramuscularly for a client with moderate persistent asthma
F. Methylergonovine 0.2 mg intramuscularly for a client with a blood pressure of 158/98 mm Hg
