,NU 170 Maternal-Child Nursing Exam 3 Comprehensive Prep 2026/2027 UPDATED – Galen
1. A nurse is caring for a client who is in the active phase of the first stage of labor. The fetal
heart rate (FHR) monitor shows a pattern of late decelerations. Which of the following is the
nurse’s priority action?
A. Turn the client to a lateral position.
B. Administer oxygen at 8 to 10 L/min via non-rebreather mask.
C. Increase the maintenance IV fluid rate.
D. Notify the healthcare provider immediately.
Answer: A
Rationale: The first priority for late decelerations is to reposition the client to a lateral
position to improve uteroplacental blood flow. Subsequent actions include increasing IV
fluids, administering oxygen, and notifying the provider.
2. A client at 34 weeks of gestation is receiving magnesium sulfate for preeclampsia. Which of
the following findings should the nurse report as a sign of magnesium toxicity?
A. Deep tendon reflexes (DTRs) of 0 or 1+.
B. Urine output of 40 mL/hr.
C. Respiratory rate of 14 breaths/min.
D. Blood pressure of 150/96 mmHg.
, Answer: A
Rationale: Magnesium sulfate is a CNS depressant; the loss of deep tendon reflexes is an
early sign of toxicity. Respiratory rate below 12 and urine output below 30 mL/hr are also
signs, but the BP given is a sign of preeclampsia, not toxicity.
3. A nurse is performing an Apgar assessment on a newborn at 1 minute. The newborn has a
heart rate of 110/min, a weak cry, some flexion of the extremities, grimaces in response to
stimuli, and a pink body with blue extremities. What is the Apgar score?
A. 5
B. 7
C. 6
D. 8
Answer: C
Rationale: HR > 100 (2), Weak cry (1), Some flexion (1), Grimace (1), Acrocyanosis (1).
Total = 6.
4. A nurse is assessing a client 2 hours postpartum and notes the fundus is boggy, displaced to
the right, and 2 cm above the umbilicus. Which of the following actions should the nurse take
first?
A. Perform vigorous fundal massage.
B. Administer oxytocin IV bolus.
