,NU 170 Exam 1 Maternal-Child Nursing Comprehensive Review 2026/2027 UPDATED – Galen
1. A client is at 28 weeks gestation and is diagnosed with gestational diabetes. Which
physiological change during pregnancy most directly contributes to insulin resistance?
A. Increase in human placental lactogen (hPL) levels
B. Decreased production of maternal cortisol
C. Elevation of maternal thyroid hormones
D. Increased renal excretion of glucose
Answer: A
Rationale: Human placental lactogen (hPL) acts as an insulin antagonist to ensure a
constant supply of glucose is available for the fetus, thereby increasing maternal insulin
resistance.
2. Using Naegele’s rule, calculate the estimated date of delivery (EDD) for a woman whose
last menstrual period (LMP) began on February 14th.
A. November 7th
B. November 21st
C. November 14th
D. October 21st
, Answer: B
Rationale: To calculate EDD using Naegele’s rule, subtract 3 months from the first day of
the LMP and add 7 days (Feb 14 - 3 months = Nov 14; Nov 14 + 7 days = Nov 21).
3. A nurse is assessing a client in the first stage of labor. The fetal heart rate (FHR) monitor
shows a pattern of late decelerations. Which action should the nurse take first?
A. Increase the IV oxytocin infusion rate
B. Prepare for an immediate amniotomy
C. Administer oxygen via nasal cannula at 2L/min
D. Turn the client to a side-lying position
Answer: D
Rationale: Late decelerations indicate uteroplacental insufficiency. The priority is to
improve blood flow by repositioning the mother to her side, followed by increasing IV
fluids and administering 10L of O2 via face mask.
4. Which GTPAL finding correctly describes a woman who is currently pregnant, has a history
of one twin birth at 35 weeks, one singleton birth at 39 weeks, and two miscarriages at 10
weeks?
A. G5, T2, P1, A2, L3
B. G4, T1, P1, A2, L2
C. G5, T1, P1, A2, L3
