Postpartum Hemorrhage: 2026 Prevention & Management
Examination Questions
1. According to the updated 2026 ACOG and SMFM guidelines, what is the clinical definition of
postpartum hemorrhage (PPH) regardless of the route of delivery?
A. Cumulative blood loss ≥ 500 mL in vaginal delivery or ≥ 1000 mL in Cesarean delivery
B. Cumulative blood loss ≥ 1000 mL or blood loss accompanied by signs or symptoms of hypovolemia within
24 hours after birth
C. Any blood loss requiring a transfusion of packed red blood cells
D. Blood loss that causes a drop in hematocrit of more than 5% from baseline
Correct Answer: B. Cumulative blood loss ≥ 1000 mL or blood loss accompanied by signs or symptoms of
hypovolemia within 24 hours after birth
Rationale: Current consensus definitions align PPH as cumulative blood loss ≥1000 mL OR blood loss
accompanied by signs/symptoms of hypovolemia (tachycardia, hypotension, tachypnea) within 24 hours after
birth, regardless of the delivery route. This replaces the older split threshold of 500 mL/1000 mL.
2. Which of the following is classified as "secondary" or "late" postpartum hemorrhage?
A. Hemorrhage occurring within the first 4 hours after birth
B. Hemorrhage occurring between 24 hours and 12 weeks postpartum
C. Hemorrhage that occurs only during the third stage of labor
D. Hemorrhage resulting from placental abruption prior to delivery
Correct Answer: B. Hemorrhage occurring between 24 hours and 12 weeks postpartum
Rationale: Primary (early) PPH occurs within the first 24 hours after delivery. Secondary (late) PPH is defined as
significant bleeding occurring from 24 hours up to 12 weeks postpartum, often caused by retained placental
fragments, subinvolution of the uterus, or infection.
3. During prenatal care, a patient is identified as having a hematocrit of 28% at 36 weeks gestation.
Why is treating maternal anemia antenatally considered a key PPH prevention strategy?
A. It directly prevents uterine atony during labor
B. It optimizes the patient's physiological reserve, allowing them to tolerate normal blood loss without
requiring emergency blood transfusion
C. It prevents the placenta from adhering too deeply to the myometrium
D. It reduces the need for delayed cord clamping at birth
Correct Answer: B. It optimizes the patient's physiological reserve, allowing them to tolerate normal blood
loss without requiring emergency blood transfusion
Rationale: Antenatal treatment of anemia (aiming for hemoglobin >11 g/dL or hematocrit >33%) does not prevent
bleeding itself, but it ensures the mother has a normal red blood cell mass. A patient with normal iron reserves can
,tolerate a 1000 mL blood loss far better than an anemic patient, who may rapidly decompensate and require blood
products.
4. In the ACOG PPH Risk Assessment Table, which of the following maternal factors places a patient
in the "high risk" category for postpartum hemorrhage?
A. Prior history of low birth weight infant
B. History of one prior low-transverse Cesarean delivery
C. Placenta previa, low-lying placenta, or suspected placenta accreta spectrum
D. Gestational diabetes controlled by diet
Correct Answer: C. Placenta previa, low-lying placenta, or suspected placenta accreta spectrum
Rationale: High-risk indicators for PPH include placenta previa/low-lying placenta, suspected placenta accreta
spectrum, active bleeding on admission, platelet count <100,000/mcL, known coagulopathy, or history of severe
PPH requiring transfusion. Prior Cesarean delivery or history of low birth weight are medium or low risk factors.
5. What is the most common cause of primary postpartum hemorrhage, accounting for up to 70-80%
of all cases?
A. Genital tract lacerations (Trauma)
B. Coagulopathy (Thrombin)
C. Retained placental fragments (Tissue)
D. Uterine atony (Tone)
Correct Answer: D. Uterine atony (Tone)
Rationale: Uterine atony (failure of the uterine myometrium to contract and compress the spiral arteries supplying
the placental site) is the leading cause of postpartum hemorrhage, followed by tissue, trauma, and thrombin.
6. A patient is at high risk for PPH. When should the first clinical risk assessment for postpartum
hemorrhage be performed?
A. Only when the patient begins to bleed excessively
B. During prenatal care, upon admission to labor and delivery, and periodically throughout labor and the
postpartum period
C. Immediately after the delivery of the placenta
D. At the 6-week postpartum follow-up visit
Correct Answer: B. During prenatal care, upon admission to labor and delivery, and periodically
throughout labor and the postpartum period
Rationale: Risk assessment for PPH is a dynamic process. It must be performed antenatally, on admission, during
labor (as new risks like chorioamnionitis or prolonged oxytocin use develop), and immediately postpartum. Many
patients who experience PPH have no identifiable risk factors initially.
,7. A patient with a history of three prior vaginal deliveries is in labor. The nurse understands that
multiparity (≥4 deliveries) is a risk factor for which PPH etiology?
A. Thrombin
B. Tissue
C. Tone
D. Trauma
Correct Answer: C. Tone
Rationale: High multiparity leads to stretching and loss of muscle tone in the myometrium over multiple
pregnancies, making the uterus less able to contract effectively after birth, increasing the risk of uterine atony.
8. Which of the following obstetric conditions is associated with "overdistension of the uterus,"
presenting a high risk for uterine atony?
A. Oligohydramnios and fetal growth restriction
B. Polyhydramnios, fetal macrosomia, and multiple gestations
C. Preterm labor at 26 weeks gestation
D. Single cephalic fetus at 39 weeks with average weight
Correct Answer: B. Polyhydramnios, fetal macrosomia, and multiple gestations
Rationale: Uterine overdistension occurs when the uterus is stretched beyond its normal limits due to excessive
amniotic fluid (polyhydramnios), a large fetus (≥4000 g), or multiple fetuses. This overstretching prevents
effective myometrial contraction after delivery.
9. Why is a prolonged labor (especially one augmented with oxytocin for many hours) a risk factor for
uterine atony?
A. It depletes the uterine muscles of glycogen and desensitizes oxytocin receptors
B. It causes cervical lacerations that prevent the uterus from contracting
C. It prevents the separation of the placenta from the uterine wall
D. It leads to maternal hyperkalemia which inhibits muscle contraction
Correct Answer: A. It depletes the uterine muscles of glycogen and desensitizes oxytocin receptors
Rationale: Prolonged labor fatigues the myometrial muscle, depleting glycogen stores. Furthermore, prolonged
exposure to exogenous oxytocin down-regulates (desensitizes) uterine oxytocin receptors, making the uterus less
responsive to both endogenous and exogenous oxytocin postpartum.
10. Immediately after delivery of the placenta, the nurse palpates the fundus and finds it soft, boggy,
and located above the umbilicus. What is the priority initial action?
A. Call the physician to prepare for surgical intervention
, B. Administer a rapid bolus of intravenous saline
C. Perform firm fundal massage until the uterus contracts and becomes firm
D. Insert a Foley catheter to empty the bladder
Correct Answer: C. Perform firm fundal massage until the uterus contracts and becomes firm
Rationale: External fundal massage is the immediate first-line physical intervention for a boggy uterus. It
stimulates the myometrium to contract, helping to close blood vessels and stop bleeding. Other actions (empty
bladder, medication) follow if massage does not maintain firmness.
11. The nurse is massaging a boggy uterus and notes that the fundus is deviated to the right and above
the umbilicus. What is the most likely cause, and what is the appropriate intervention?
A. Retained placental tissue; perform manual exploration of the uterus
B. Urinary bladder distension; assist the patient to void or perform sterile catheterization
C. Cervical laceration; notify the provider for speculum exam
D. Normal postpartum anatomical shift; continue fundal massage only
Correct Answer: B. Urinary bladder distension; assist the patient to void or perform sterile catheterization
Rationale: A full bladder displaces the uterus upward and to the side (usually the right), preventing the
myometrium from contracting effectively. Emptying the bladder allows the uterus to return to the midline and
contract.
12. A patient is experiencing severe uterine atony that does not respond to fundal massage. The
obstetrician inserts one hand into the vagina to press against the anterior uterine wall, while the other
hand presses down on the abdomen to compress the uterus. What is this maneuver called?
A. Credé maneuver
B. Bimanual uterine compression
C. Brand-Andrews maneuver
D. Zavanelli maneuver
Correct Answer: B. Bimanual uterine compression
Rationale: Bimanual compression involves placing one hand in the vagina forming a fist against the anterior
cervix/uterus, and the other hand externally on the abdomen pushing the posterior wall toward the fist. This
physically compresses the bleeding sinuses until uterotonics take effect.
13. Which of the following medications administered during labor increases the risk of postpartum
hemorrhage due to myometrial relaxation?
A. Oxytocin
B. Magnesium Sulfate
C. Penicillin G
D. Phytonadione (Vitamin K)
