Maternal Newborn Nursing Test Maternity Nursing: Antepartum 5

Question 1

A client at 16 weeks gestation undergoes a quadruple screen (quad screen). Elevated alpha-fetoprotein (AFP) is MOST associated with:

Accepted Answer

Open neural tube defects such as spina bifida

Answer

Elevated maternal serum AFP is most strongly associated with open neural tube defects, where AFP leaks from fetal spinal fluid into amniotic and maternal blood.

Question 2

A client at 37 weeks gestation reports leaking fluid. The nurse uses nitrazine paper to test the fluid. Which result indicates rupture of membranes?

Accepted Answer

Nitrazine paper turns blue-green to blue (pH ≥6.5)

Answer

Amniotic fluid is alkaline (pH 7.1–7.3), turning nitrazine paper blue-green to blue, distinguishing it from acidic vaginal secretions.

Question 3

A nurse is caring for a client at 31 weeks gestation who is receiving magnesium sulfate for preterm labor. Which assessment finding signals magnesium toxicity requiring the nurse to stop the infusion?

Accepted Answer

Absent deep tendon reflexes

Answer

Loss of deep tendon reflexes (hyperreflexia resolution) is an early sign of magnesium toxicity and requires the infusion to be stopped immediately; the antidote is calcium gluconate.

Question 4

A client at 20 weeks gestation is found to have an incompetent cervix. The nurse anticipates which treatment will be prescribed?

Accepted Answer

Cervical cerclage placement

Answer

A cervical cerclage (purse-string suture placed around the cervix) is the primary surgical treatment for incompetent cervix to prevent premature dilation.

Question 5

A gravida 3, para 2 client at 35 weeks gestation has a hemoglobin of 9.2 g/dL. The nurse identifies this as:

Accepted Answer

Iron-deficiency anemia requiring intervention

Answer

A hemoglobin below 10.5 g/dL in the third trimester is below the threshold for physiologic anemia and indicates true iron-deficiency anemia requiring treatment.
