PNR 203/PNR203 Exam 1 V3 | Maternal-Newborn
Nursing Q&A with Rationale | Fortis College
1. A nurse is calculating a client’s expected date of delivery (EDD) using Naegele’s rule. The
client’s last menstrual period (LMP) began on March 10. Which of the following dates should
the nurse identify as the EDD?
A. December 17
B. December 3
C. January 17
D. November 10
Correct Answer: A
Explanation: To calculate the EDD using Naegele’s rule, subtract 3 months from the first
day of the LMP and add 7 days and 1 year. Subtracting 3 months from March gives
December, and adding 7 days to March 10 results in December 17. This rule assumes a
standard 28-day menstrual cycle.
2. A nurse is assessing a pregnant client who reports her last menstrual period was May 8th.
What is her estimated date of birth (EDB)?
A. February 15
B. February 1
C. February 8
,D. February 22
Correct Answer: A
Explanation: Using Naegele’s rule, the nurse subtracts three months from May, which
leads to February. Adding seven days to the 8th results in the 15th of February. This
method is the standard way to estimate the delivery date based on a 28-day cycle.
3. A nurse is performing an assessment on a client who is at 20 weeks of gestation. At which
of the following locations should the nurse expect to palpate the fundus?
A. Umbilicus
B. Xiphoid process
C. Symphysis pubis
D. Halfway between the symphysis pubis and umbilicus
Correct Answer: A
Explanation: At 20 weeks of gestation, the fundus is typically located at the level of the
umbilicus. Before this, at 12 weeks it is at the symphysis pubis, and at 16 weeks it is
halfway between the two. Measurement of fundal height is a key indicator of fetal growth
and gestational age.
4. A nurse is teaching a client about positive signs of pregnancy. Which of the following
findings should the nurse include?
A. Fetal heart tones heard by Doppler
, B. Positive pregnancy test
C. Amenorrhea
D. Quickening
Correct Answer: A
Explanation: Positive signs of pregnancy are those that can be attributed only to the
presence of a fetus, such as hearing fetal heart tones or visualizing the fetus on ultrasound.
Presumptive signs are subjective, like amenorrhea and quickening. Probable signs are
objective but not definitive, like a positive pregnancy test.
5. A nurse is caring for a client who is at 32 weeks of gestation and is receiving magnesium
sulfate IV for preeclampsia. Which of the following findings should the nurse identify as a sign
of magnesium toxicity?
A. Hyperreflexia
B. Respiratory rate of 10/min
C. Urinary output of 40 mL/hr
D. Fetal heart rate of 150/min
Correct Answer: B
Explanation: Magnesium sulfate is a CNS depressant; therefore, a respiratory rate less
than 12/min is a sign of toxicity. Other signs include the loss of deep tendon reflexes and a
