1 | Postpartum DVT: Improvement vs Worsening
ANSWER TO KNOW: Decreasing unilateral edema suggests improvement; increasing warmth/redness/swelling suggests worsening.
WHY: A DVT improves as local inflammation and obstruction resolve. New warmth, erythema, swelling, or sudden dyspnea raises
concern for progression or embolization. The key testing distinction is: Postpartum + unilateral leg change = trend the affected
extremity and watch for PE clues. Avoid the common distractor: Scant lochia and mild leukocytosis can be expected postpartum and
do not measure DVT progression.
QUESTION HINT: Postpartum + unilateral leg change = trend the affected extremity and watch for PE clues.
DON'T CONFUSE IT WITH: Scant lochia and mild leukocytosis can be expected postpartum and do not measure DVT progression.
2 | Postpartum Endometritis
ANSWER TO KNOW: Expect fever, uterine/fundal tenderness, malaise, and abnormal or foul-smelling lochia; broad-spectrum
antibiotics and fluids are typical treatment.
WHY: Postpartum endometritis is an infection of the uterine lining. Cesarean birth and prolonged rupture of membranes increase the
risk. Expected findings include fever, uterine or fundal tenderness, tachycardia, chills, malaise, decreased appetite, and foul-
smelling or abnormal lochia. Broad-spectrum antibiotics treat the infection, while fluids support hydration; temperature and lochia
should be followed for response to treatment.
QUESTION HINT: Postpartum fever + uterine tenderness + foul lochia = endometritis.
DON'T CONFUSE IT WITH: A temperature of 37.4 C alone is not the classic febrile pattern.
3 | Postpartum Hemorrhage: Uterine Atony
ANSWER TO KNOW: A boggy/soft uterus, heavy lochia, or lateral fundal displacement requires prompt follow-up.
WHY: A soft or boggy uterus cannot contract effectively enough to compress the open vessels at the placental site, which increases
postpartum bleeding. Fundal massage stimulates contraction. A laterally displaced fundus can indicate bladder distention, and a full
bladder can interfere with effective uterine contraction, so bladder assessment and emptying may also be necessary.
QUESTION HINT: Boggy + bleeding = massage fundus; displaced fundus = think full bladder.
DON'T CONFUSE IT WITH: Normal postpartum edema or soft breasts are not primary hemorrhage clues.
4 | Rapid Labor / Precipitous Birth
ANSWER TO KNOW: Rapid cervical dilation and birth increase risk for postpartum hemorrhage from uterine fatigue/atony and
trauma.

WHY: Very fast labor can leave the uterus less able to contract effectively after birth and can increase tissue injury. The key testing
distinction is: 80% effaced + 8 cm after only about 1 hour = think precipitous labor risk. Avoid the common distractor: Cervical
insufficiency and ectopic pregnancy do not fit active rapid term labor.
QUESTION HINT: 80% effaced + 8 cm after only about 1 hour = think precipitous labor risk.
DON'T CONFUSE IT WITH: Cervical insufficiency and ectopic pregnancy do not fit active rapid term labor.
5 | Immediate Postpartum Hemorrhage: First Action
ANSWER TO KNOW: Massage the fundus first when excessive bleeding is accompanied by uterine atony.
WHY: Uterine atony is the most common cause of early postpartum hemorrhage. When excessive vaginal bleeding occurs with a
boggy uterus, fundal massage is the first action because it stimulates uterine contraction and helps compress bleeding vessels at the
placental site. Additional interventions may be needed, but restoring uterine tone is the immediate priority when atony is evident.
QUESTION HINT: Heavy postpartum bleeding + boggy uterus = FUNDUS FIRST.
DON'T CONFUSE IT WITH: Oxytocin and bladder emptying may follow, but a boggy fundus makes massage the immediate move.
6 | Postpartum Hemorrhage: Misoprostol
ANSWER TO KNOW: Anticipate a uterotonic such as misoprostol for uterine atony when prescribed.
WHY: Misoprostol is a prostaglandin uterotonic that promotes uterine contraction, helping compress vessels at the placental site and
decrease bleeding caused by uterine atony. In the supplied question, a large amount of lochia with uterine atony points toward a
uterotonic rather than interventions aimed at fetal lung maturity or unrelated testing.
QUESTION HINT: Atony + large bleeding = uterotonic territory.
DON'T CONFUSE IT WITH: Betamethasone matures fetal lungs; methylergonovine has important hypertension precautions.
7 | Postpartum Anemia
ANSWER TO KNOW: A stable postpartum client with low hemoglobin/hematocrit may be treated with iron supplementation.
WHY: Iron supports red blood cell recovery when there is anemia without ongoing major hemorrhage or instability. The key testing
distinction is: Low Hgb/Hct but stable = think iron, not automatically transfusion. Avoid the common distractor: Tamponade, large-
bore IV resuscitation, and transfusion are for active/severe bleeding or instability.
QUESTION HINT: Low Hgb/Hct but stable = think iron, not automatically transfusion.
DON'T CONFUSE IT WITH: Tamponade, large-bore IV resuscitation, and transfusion are for active/severe bleeding or instability.
8 | Postpartum Preeclampsia
ANSWER TO KNOW: Severe postpartum hypertension with headache requires prompt evaluation; obtain ordered urine testing for
protein and assess for severe features.
WHY: Hypertension with a severe headache after delivery is concerning because preeclampsia can occur or persist postpartum. The
client requires prompt assessment for evidence of end-organ involvement, including evaluation for proteinuria and other
manifestations of the hypertensive disorder. Delivery does not immediately eliminate the risk of preeclampsia complications.
QUESTION HINT: Postpartum + very high BP + headache = preeclampsia until proven otherwise.
DON'T CONFUSE IT WITH: Do not dismiss symptoms because the baby has already been delivered.
