NU 170 Exam 3 Maternal-Child Nursing
(2026/2027) PDF | Nursing | Galen College
1. A nurse is assessing a client in active labor. The fetal
heart rate (FHR) baseline is 170 beats/min. Which action
should the nurse take first?
A) Document the finding as normal
B) Administer oxygen via face mask
C) Turn the client on her left side
D) Notify the healthcare provider
1
,Correct Answer: C
Rationale: Normal FHR baseline is 110–160 bpm.
Tachycardia (>160) can indicate maternal fever,
dehydration, or infection. The first action is maternal
repositioning to improve placental perfusion, then oxygen,
IV fluids, and provider notification.
2. A patient’s contractions are every 2–3 minutes, lasting
70 seconds, with moderate intensity. The cervix is 7 cm
dilated. Which phase of labor is the client in?
A) Latent phase
B) Active phase
C) Transition phase
2
,D) Descent phase
Correct Answer: B
Rationale: Active labor is 6–7 cm to complete dilatation
(10 cm). Contractions are strong, 2–3 min apart, lasting
45–70 seconds. Transition (8–10 cm) has contractions
every 1.5–2 min lasting 60–90 sec.
3. A nurse notes late decelerations on the fetal monitor.
Which intervention is most important?
A) Increase IV fluids
B) Turn client to left lateral position
3
, C) Prepare for immediate cesarean section
D) Administer tocolytics
Correct Answer: B
Rationale: Late decelerations indicate uteroplacental
insufficiency. First-line interventions: position change (left
lateral), correct hypotension, oxygen, increase IV fluids.
C-section only if uncorrectable.
4. Which medication is used to treat postpartum
hemorrhage caused by uterine atony?
A) Magnesium sulfate
