NR 327 Maternal-Child Nursing Week 10 Study Guide 2026
|Chamberlain College
1. A nurse is calculating a client’s expected date of delivery (EDD) using Nagele’s
rule. The client’s last menstrual period (LMP) began on April 10. What is the
EDD?
A. January 10
B. July 17
C. January 17
D. January 3
Answer: C
Rationale: Nagele’s rule is calculated by subtracting 3 months and adding 7 days and 1
year to the first day of the LMP. April minus 3 months is January; 10 plus 7 days is 17.
2. At how many weeks gestation is the fundus typically at the level of the
umbilicus?
A. 12 weeks
B. 20 weeks
C. 16 weeks
D. 24 weeks
Answer: B
Rationale: By 20 weeks of gestation, the fundus is usually located at the level of the
umbilicus.
,3. A client at 32 weeks gestation is diagnosed with preeclampsia. Which of the
following findings should the nurse report to the provider immediately?
A. Blurred vision
B. 1+ pedal edema
C. Weight gain of 1 lb in a week
D. Increased urine output
Answer: A
Rationale: Blurred vision is a sign of severe preeclampsia and potential central nervous
system involvement, indicating a risk for seizure.
4. What is the primary purpose of administering magnesium sulfate to a client
with preeclampsia?
A. To lower blood pressure
B. To induce labor
C. To increase urine output
D. To prevent seizures
Answer: D
Rationale: Magnesium sulfate is a CNS depressant primarily used in preeclampsia for
seizure prophylaxis (preventing eclampsia).
5. A nurse is monitoring a client receiving magnesium sulfate. Which finding
indicates magnesium toxicity?
A. Respiratory rate of 10/min
B. Hyperactive deep tendon reflexes
C. Urinary output of 40 mL/hr
D. Blood pressure 140/90 mmHg
Answer: A
Rationale: Signs of magnesium toxicity include respiratory depression (less than 12/min),
loss of deep tendon reflexes, and decreased urine output.
, 6. Which medication should the nurse have available as an antidote for
magnesium sulfate toxicity?
A. Naloxone
B. Terbutaline
C. Oxytocin
D. Calcium gluconate
Answer: D
Rationale: Calcium gluconate is the specific antidote for magnesium sulfate toxicity.
7. A client is in the first stage of labor, active phase. Which cervical dilation
range defines this phase?
A. 0 to 3 cm
B. Full dilation to birth
C. 8 to 10 cm
D. 4 to 7 cm
Answer: D
Rationale: The active phase of the first stage of labor is characterized by cervical dilation
from 4 to 7 cm.
8. Which fetal heart rate pattern is caused by fetal head compression during
contractions?
A. Prolonged decelerations
B. Late decelerations
C. Variable decelerations
D. Early decelerations
Answer: D
Rationale: Early decelerations are benign and are caused by compression of the fetal head
during contractions.
