Question 1

A patient with chronic hypertension becomes pregnant. Which antihypertensive medication is considered UNSAFE during pregnancy?

Accepted Answer

ACE inhibitors

Answer

ACE inhibitors are contraindicated in pregnancy because they cause fetal renal dysplasia, oligohydramnios, and fetal death, especially in the second and third trimesters.

Question 2

A patient at 16 weeks has an elevated maternal serum alpha-fetoprotein (MSAFP). Which condition does this most likely suggest?

Accepted Answer

Open neural tube defect

Answer

Elevated MSAFP is associated with open fetal defects such as neural tube defects (anencephaly, spina bifida) where AFP leaks into maternal circulation.

Question 3

A pregnant patient is diagnosed with a deep vein thrombosis at 22 weeks. Which anticoagulant is the preferred treatment?

Accepted Answer

Low-molecular-weight heparin (LMWH)

Answer

Low-molecular-weight heparin is preferred in pregnancy because it does not cross the placenta, unlike warfarin which is teratogenic, especially in the first trimester.

Question 4

A patient at 32 weeks has polyhydramnios (AFI of 28 cm). Which fetal condition should the nurse anticipate evaluating for?

Accepted Answer

Gastrointestinal obstruction or fetal swallowing disorder

Answer

Polyhydramnios is associated with conditions that impair fetal swallowing (e.g., esophageal atresia, anencephaly) because the fetus normally recycles amniotic fluid by swallowing.

Question 5

Which assessment is essential before administering the first dose of magnesium sulfate to a patient with severe preeclampsia?

Accepted Answer

Assessing deep tendon reflexes, respiratory rate, and urine output

Answer

Baseline deep tendon reflexes, respiratory rate (must be ≥12/min), and urine output (must be ≥25-30 mL/hr) must be assessed before initiating magnesium therapy.
