,NU 170 Maternal-Child Nursing Exam 2 Comprehensive Review 2026/2027 UPDATED- Galen
1. A nurse is caring for a client with severe preeclampsia who is receiving intravenous
magnesium sulfate. Which finding should the nurse report to the provider immediately?
A. Feeling of warmth and flushing
B. Deep tendon reflexes of 2+
C. Urinary output of 40 mL/hr
D. Feeling of warmth and flushing
D. Respiratory rate of 10/min
Answer: D
Rationale: Magnesium sulfate is a CNS depressant. A respiratory rate below 12/min is a
sign of magnesium toxicity and requires immediate intervention, including stopping the
infusion and potentially administering calcium gluconate.
2. A client in the active phase of labor has a fetal heart rate (FHR) monitor showing late
decelerations. What is the nurse’s priority action?
A. Increase the rate of the oxytocin infusion
B. Perform a vaginal examination to check for cord prolapse
C. Turn the client to the left side-lying position
, D. Administer oxygen at 2 L/min via nasal cannula
Answer: C
Rationale: Late decelerations indicate uteroplacental insufficiency. The priority is to
improve oxygenation by turning the mother to her side to relieve pressure on the inferior
vena cava and increase blood flow to the placenta.
3. A nurse is assessing a newborn 1 minute after birth. The newborn has a heart rate of
110/min, a weak cry, some flexion of the extremities, grimacing, and a pink body with blue
extremities. What is the Apgar score?
A. 6
B. 5
C. 7
D. 8
Answer: A
Rationale: Heart rate >100 (2), Weak cry (1), Some flexion (1), Grimace (1), Acrocyanosis
(1). Total = 6.
4. Which medication is the antidote for magnesium sulfate toxicity?
A. Naloxone
B. Terbutaline
