Postpartum Hemorrhage nursing care: what to assess and what to do first
Written and reviewed by Dana Whitfield, RN, MSN · 6 min read · Updated September 2026
Short answer
Massage the fundus first. A boggy, poorly contracted uterus causes most postpartum hemorrhage, so before you look for a laceration or call for help, put a hand on the fundus and assess its tone. If it firms with massage and bleeding slows, you have your cause and your first intervention in one motion.
The pathophysiology in one pass
After the placenta separates, the uterus depends on myometrial contraction to compress the spiral arteries that fed it. That contraction is the only thing standing between the mother and continuous arterial bleeding at the placental site. When the myometrium fails to contract, or contracts and then relaxes again, those vessels stay open and blood loss continues unchecked. This is uterine atony, and it accounts for roughly 70-80% of postpartum hemorrhage cases.
The remaining causes follow the same four-T framework: trauma to the genital tract, retained tissue that prevents full contraction, and thrombin problems from a coagulopathy. Atony is overwhelmingly the most common and the most reversible at the bedside, which is why it drives the first response. A uterus that is overdistended from twins, polyhydramnios, or a macrosomic infant, or one that has been in prolonged or augmented labor, is at higher risk of failing to clamp down.
Assessment findings that matter
The defining finding is uterine tone. A fundus that feels soft, boggy, or difficult to locate on palpation is atony until proven otherwise, and it should prompt immediate massage rather than a search for other causes first. A firm fundus with ongoing bright red bleeding points you toward a laceration instead, but that assessment comes second, not first.
Quantify blood loss rather than estimating by eye; visual estimation reliably underestimates true loss. Weigh saturated pads and linens, and use collection drapes where available. Track vital signs against the physiologic reserve of pregnancy: a postpartum patient can lose a significant volume before tachycardia or hypotension appears, because pregnancy increases blood volume by 40-50%. A rising pulse with a normal blood pressure is an early warning sign, not a reassuring one. Watch for a full bladder too, since a distended bladder displaces and prevents the uterus from contracting.
What the exam asks about this
NCLEX items on postpartum hemorrhage almost always test sequencing: what do you do first when a nurse finds a boggy fundus with heavy lochia. The correct first action is fundal massage, not calling the provider, not starting oxytocin, and not checking vital signs again. Massage is the immediate, nurse-initiated intervention that addresses the most likely cause on the spot.
Expect questions that ask you to distinguish atony from laceration using the classic contrast: a boggy uterus with steady bleeding is atony, while a firm uterus with continuous bright red bleeding suggests trauma. You may also see items on quantifying blood loss, recognizing early compensatory tachycardia before hypotension develops, and prioritizing interventions in order- massage, empty the bladder, medications, then escalate. Select-all-that-apply questions often list appropriate first-line actions and require you to exclude ones that are correct but not first, like administering oxytocin before you have attempted massage.
Nursing interventions in priority order
Start with fundal massage: cup one hand above the symphysis to support the lower uterine segment and use the other to massage the fundus firmly in a circular motion until it firms. Assess and empty the bladder, either by encouraging voiding or by straight catheterization, since a full bladder is a common and easily corrected contributor to atony. Increase the rate of the existing IV infusion or establish a second large-bore IV access if none exists, anticipating the need for fluids, blood products, or medications.
Continue to monitor vital signs, level of consciousness, skin color and temperature, and urine output as ongoing indicators of perfusion. Keep a running, weighed estimate of blood loss rather than a visual guess. If bleeding continues despite a firm fundus, inspect for lacerations and prepare for a provider to examine the cervix and vaginal walls. Document timing, interventions, and response at each step, since this record drives the escalation decision that follows.
Medications and monitoring
Oxytocin is the first-line uterotonic, typically given as a dilute IV infusion, and it is often already running prophylactically after delivery. If bleeding continues despite oxytocin and a firm fundus cannot be maintained, methylergonovine may be given intramuscularly, but it is contraindicated in hypertension and preeclampsia because it raises blood pressure. Carboprost, a prostaglandin analog given IM, is avoided in asthma because it can trigger bronchospasm. Misoprostol, given rectally, orally, or sublingually, is an option when the others are contraindicated or unavailable.
Know each drug's contraindication as well as its use, since exam items frequently test which uterotonic to withhold given a specific comorbidity. Monitor blood pressure closely after methylergonovine and carboprost, and reassess fundal tone after each dose. Track hemoglobin and hematocrit trends, coagulation studies if hemorrhage is significant, and type and crossmatch status so blood products are ready if needed.
When to escalate
Escalate immediately if the fundus will not stay firm despite massage and a first-line uterotonic, if bleeding continues with a firm fundus, or if vital signs show a sustained rise in heart rate, a falling blood pressure, or declining urine output. These patterns suggest a cause massage cannot fix, such as retained placental fragments, a coagulopathy, or an unrecognized laceration, and they call for provider evaluation, additional uterotonics, and likely transfer to a higher level of monitoring.
Activate your unit's massive transfusion or hemorrhage protocol if blood loss exceeds 1000 mL with signs of hypovolemia, per the current definition of postpartum hemorrhage. Have a second nurse call for help while you stay with the patient, and prepare for interventions beyond nursing scope, including uterine balloon tamponade, surgical management, or return to the operating room. Early, clear communication of blood loss volume and trend is what allows the team to escalate in time.
The next step on this is the same as on everything else here: answer questions and read the rationales. Our maternity and newborn practice questions are the closest set to what this page covers.
Common questions
What is the first nursing action for a boggy postpartum uterus?
Fundal massage, performed immediately at the bedside. Support the lower uterine segment with one hand above the symphysis pubis while massaging the fundus firmly with the other until it contracts. This is a nurse-initiated intervention that does not require a physician order.
How much blood loss defines postpartum hemorrhage?
Current definitions set the threshold at 1000 mL or more of cumulative blood loss within 24 hours of birth, for both vaginal and cesarean delivery, accompanied by signs or symptoms of hypovolemia. Earlier definitions used 500 mL for vaginal birth, so older exam material may still reflect that figure.
Why does a full bladder cause postpartum hemorrhage?
A distended bladder sits anterior to the uterus and displaces it upward and to the side, which prevents the myometrium from contracting effectively. Emptying the bladder, by voiding or catheterization, is a quick correction that often restores fundal tone.
Which uterotonic is contraindicated in hypertension?
Methylergonovine is contraindicated in patients with hypertension or preeclampsia because it causes vasoconstriction and can raise blood pressure sharply. Carboprost is avoided instead in patients with asthma due to the risk of bronchospasm.
How do you tell atony from a laceration as the cause of bleeding?
A boggy, soft fundus with steady bleeding points to atony, and massage is the immediate response. A firm, well-contracted fundus with continuous bright red bleeding suggests a laceration, which needs direct visual inspection by the provider rather than massage.
