,Section A - Maternity Nursing Overview
Q1.
During a prenatal visit, a client at 20 weeks gestation reports new-onset blurred vision and
facial edema. Which pathophysiological mechanism best explains the potential link
between these symptoms and the development of preeclampsia?
A. Increased cardiac output leading to B. Systemic vasospasm and endothelial
pulmonary congestion dysfunction causing reduced perfusion and
fluid shift
C. Hepatic capsule stretching due to edema D. Gestational diabetes-induced
microvascular damage
Correct: B - Systemic vasospasm and endothelial dysfunction causing reduced perfusion
and fluid shift
Rationale:Preeclampsia involves generalized vasospasm and endothelial dysfunction,
leading to hypertension, proteinuria, and edema. Blurred vision results from retinal arteriolar
spasm, and facial edema reflects increased capillary permeability and fluid retention. The
other options do not directly explain the combination of visual and edematous changes.
Q2.
A pregnant client at 32 weeks gestation is diagnosed with oligohydramnios. Which fetal
anomaly is most likely to be associated with this condition?
A. Anencephaly B. Esophageal atresia
C. Posterior urethral valves D. Duodenal atresia
Correct: C - Posterior urethral valves
Rationale:Oligohydramnios is commonly caused by fetal urinary tract obstructions such as
posterior urethral valves, which impair urine output and thus amniotic fluid production.
Anencephaly may cause polyhydramnios due to decreased fetal swallowing, and esophageal
atresia and duodenal atresia also lead to polyhydramnios.
Q3.
Which of the following best describes the physiological mechanism that prevents
menstruation during early pregnancy?
A. Continuous high levels of estrogen and B. Suppression of gonadotropin-releasing
progesterone from the corpus luteum and hormone by human chorionic gonadotropin
placenta
Page 3
, Section A - Maternity Nursing Overview
C. Atrophy of the endometrium due to D. Negative feedback of human placental
trophoblast invasion lactogen on the anterior pituitary
Correct: A - Continuous high levels of estrogen and progesterone from the corpus luteum
and placenta
Rationale:The corpus luteum secretes estrogen and progesterone, maintaining the
endometrium until the placenta takes over. hCG sustains the corpus luteum but does not
directly suppress GnRH. Endometrial atrophy is not a mechanism; trophoblast invasion does
not cause atrophy. hPL is not involved in maintaining the endometrium.
Q4.
A nurse is reviewing a client's prenatal record. The client's rubella titer is reported as 1:8.
Which interpretation and action is most appropriate?
A. Immune; no further action needed B. Susceptible; administer MMR vaccine
immediately
C. Susceptible; administer MMR vaccine D. Equivocal; repeat titer in 4 weeks
postpartum
Correct: C - Susceptible; administer MMR vaccine postpartum
Rationale:A rubella titer of 1:8 is considered nonimmune (susceptible). Live vaccines such as
MMR are contraindicated during pregnancy. Therefore, the vaccine should be given
postpartum. Immediate administration is unsafe, and repeating the titer is unnecessary.
Q5.
Which maternal serum marker is most indicative of an open neural tube defect when
elevated at 16 weeks gestation?
A. Pregnancy-associated plasma protein A B. Alpha-fetoprotein (AFP)
(PAPP-A)
C. Human chorionic gonadotropin (hCG) D. Unconjugated estriol
Correct: B - Alpha-fetoprotein (AFP)
Rationale:Elevated AFP in maternal serum is a screening marker for open neural tube
defects, as AFP leaks from the fetal spine into amniotic fluid and then into maternal blood.
PAPP-A and hCG are markers for aneuploidy, and low estriol is associated with certain
chromosomal abnormalities.
Q6.
A client at 28 weeks gestation reports dizziness when lying supine. Which physiological
change is the primary cause of this symptom?
