DELIVERY – UNFOLDING REASONING CASE STUDY EXAM
LATEST VERSION QUESTIONS AND ANSWERS 2026 EDITION
ABRUPTION PLACENTAE WITH PRETERM LABOR AND DELIVERY – UNFOLDING
REASONING CASE STUDY – 250 QUESTIONS WITH RATIONALES
SECTION 1: HISTORY & DATA COLLECTION (Questions 1-50)
History of Present Problem & Risk Factors
1. What is the most significant risk factor for placental abruption in Michelle's
history?
A) Her age of 38 years
B) Her previous history of partial abruption
C) Her employment in fast food
D) Her late initiation of prenatal care
Correct Answer: B
Rationale: A previous history of placental abruption is the most significant risk factor
for recurrence, with recurrence rates estimated at 10-17% . While advanced maternal
age and late prenatal care are risk factors, a prior abruption carries the highest
predictive value for this pregnancy.
2. What is the definition of gravida in obstetrics?
A) The number of pregnancies carried to term
B) The total number of pregnancies a woman has had
C) The number of living children a woman has
D) The number of pregnancies reaching 20 weeks
Correct Answer: B
, Page 2 of 61
Rationale: Gravida refers to the total number of pregnancies a woman has had,
regardless of outcome. Para refers to pregnancies that have reached 20 weeks or more .
3. Michelle is documented as Gravida 4, Para 1. What does this mean?
A) She has been pregnant 4 times and has 1 living child
B) She has been pregnant 4 times and has 1 pregnancy reaching viability
C) She has 4 children and 1 pregnancy loss
D) She has been pregnant once and has 4 children
Correct Answer: B
Rationale: Gravida 4 = 4 pregnancies; Para 1 = 1 pregnancy reaching viability (her 35-
week son). The other pregnancies include two spontaneous abortions (first trimester
losses) and the current pregnancy. Para counts pregnancies reaching viability (20 weeks
or more), not necessarily living children .
4. Which of the following is a classic manifestation of placental abruption?
A) Painless bright red vaginal bleeding
B) Sudden, severe abdominal pain with a rigid, board-like uterus
C) Gradual onset of pelvic pressure
D) Fetal heart rate accelerations
Correct Answer: B
Rationale: Classic manifestations of abruptio placentae include sudden, severe
abdominal pain, dark red vaginal bleeding, uterine tenderness, and a rigid, board-like
abdomen . Painless bright red bleeding is characteristic of placenta previa.
5. What is the primary pathophysiological mechanism in placental abruption?
A) The placenta covers the cervical os
B) Premature separation of the placenta from the uterine wall
C) The umbilical cord becomes compressed
D) The amniotic sac ruptures prematurely
Correct Answer: B
Rationale: Abruptio placentae is the premature separation of the placenta from the
uterine wall after the twentieth week of gestation and before the fetus is delivered . This
separation compromises fetal oxygenation and can lead to maternal hemorrhage.

6. What is the clinical significance of a rigid, board-like abdomen in placental
abruption?
A) Indicates the uterus is contracting normally
B) Suggests blood has penetrated the myometrium, causing uterine irritability
C) Is a normal finding in pregnancy
D) Indicates the fetus is in a breech position
Correct Answer: B
Rationale: A rigid, board-like abdomen occurs when blood penetrates the myometrium
and causes uterine irritability . This is a classic sign of placental abruption and indicates
significant bleeding into the uterine wall.
7. Michelle reports decreased fetal movement. What is the clinical significance of
this finding?
A) It is a normal finding in the third trimester
B) It indicates the fetus may be compromised due to hypoxia
C) It means the baby is sleeping
D) It is not a cause for concern
Correct Answer: B
Rationale: Decreased fetal movement is a warning sign of fetal compromise, likely due
to hypoxia from placental separation . The placenta provides oxygen and nutrients;
when it separates, fetal oxygenation is compromised.
8. Based on Michelle's social history, what is a significant modifiable risk factor for
placental abruption?
A) Working evening shifts
B) Smoking 10 cigarettes daily
C) Being estranged from the father
D) Eating fried foods
Correct Answer: B
Rationale: Tobacco use (smoking) is a significant modifiable risk factor for placental
abruption . Smoking is associated with vascular damage and placental insufficiency.
While other factors are present, smoking is the most modifiable risk factor that directly
impacts placental health.

9. Michelle was tested for sickle cell trait and found to be a carrier. What is the
significance of this finding?
A) It increases her risk of placental abruption
B) It is not relevant unless the father is also a carrier
C) It is unrelated to placental abruption
D) It guarantees the baby will have sickle cell disease
Correct Answer: B
Rationale: While sickle cell trait is not directly a risk factor for placental abruption, it is
relevant for fetal screening. The father's status is unknown; if both parents are carriers,
the baby has a 25% chance of having sickle cell disease .
10. What is the expected outcome for Michelle's prenatal vitamin prescription?
A) Prevention of nausea
B) Maintenance of adequate iron and vitamin levels during pregnancy
C) Prevention of preterm labor
D) Treatment of gestational diabetes
Correct Answer: B
Rationale: Prenatal vitamins provide essential nutrients, including folic acid and iron, to
support maternal and fetal health. The expected outcome is maintenance of adequate
iron and vitamin levels during pregnancy .
Social History & Psychosocial Factors
11. Michelle smokes 10 cigarettes daily despite knowing the risks. What is the most
appropriate nursing response?
A) "You should quit immediately for your baby's health."
B) "I understand quitting is difficult, especially with stress. What support would help you
reduce or quit?"
C) "Smoking is not that harmful in pregnancy."
D) "You need to stop smoking now."
Correct Answer: B
Rationale: A non-judgmental, supportive approach that acknowledges the difficulty of
quitting and explores patient-identified support is the most therapeutic. This approach
respects the patient's autonomy while providing education and resources .
