Questions with Correct Answers and Expert
Explanation for Each Question | Galen
1. A nurse is calculating the estimated date of delivery (EDD) for a client whose last
menstrual period (LMP) began on February 15. Using Nagele’s rule, what is the correct
EDD?
A. November 22
B. November 8
C. May 22
D. November 15
Correct Answer: A
Expert Explanation: To use Nagele’s rule, the nurse subtracts 3 months from the
first day of the LMP and adds 7 days. Subtracting 3 months from February 15 leads
to November 15, and adding 7 days results in November 22. This calculation is
based on a 28-day menstrual cycle and helps guide prenatal care timing.
2. Which of the following is considered a presumptive sign of pregnancy?
A. Positive pregnancy test
B. Fetal heart tones
C. Hegar’s sign
,D. Amenorrhea
Correct Answer: D
Expert Explanation: Presumptive signs are subjective changes reported by the
client that could suggest pregnancy but are not diagnostic. Amenorrhea, or the
absence of menstruation, is a classic presumptive sign often noticed first. Other
presumptive signs include breast tenderness, fatigue, and nausea.
3. A client in her second trimester reports feeling faint when lying flat on her back.
Which intervention should the nurse recommend?
A. Sit up quickly to restore blood flow
B. Turn onto her side, preferably the left side
C. Drink more caffeine to increase blood pressure
D. Breathe into a paper bag
Correct Answer: B
Expert Explanation: This condition is known as supine hypotensive syndrome,
caused by the heavy uterus compressing the inferior vena cava. Turning to the side,
especially the left side, relieves pressure on the vessel and improves cardiac output.
The nurse should educate the client to avoid the supine position during late
pregnancy.
,4. What is the primary purpose of administering Folic Acid during the preconception
period and early pregnancy?
A. To prevent gestational diabetes
B. To reduce the risk of neural tube defects
C. To treat iron-deficiency anemia
D. To prevent morning sickness
Correct Answer: B
Expert Explanation: Folic acid is critical for proper closure of the neural tube in the
developing embryo during the first few weeks of pregnancy. Adequate intake of 400
to 800 mcg daily significantly reduces the incidence of defects such as spina bifida.
Most neural tube defects occur before a woman even knows she is pregnant,
emphasizing the importance of preconception supplementation.
5. A nurse is assessing a newborn and notes a heart rate of 110, a strong cry, some
flexion of the extremities, a sneeze when suctioned, and a completely pink body.
What is the APGAR score?
A. 7
B. 8
C. 9
, D. 10
Correct Answer: C
Expert Explanation: The newborn receives 2 points for heart rate (over 100), 2
points for respiratory effort (strong cry), 1 point for muscle tone (some flexion), 2
points for reflex irritability (sneeze), and 2 points for color (completely pink). This
totals 9 out of 10 points. APGAR scores are typically performed at 1 and 5 minutes
after birth to evaluate neonatal transition.
6. Which hormone is primarily responsible for maintaining the endometrial lining
during early pregnancy until the placenta takes over?
A. Progesterone
B. Human growth hormone
C. Estrogen
D. Oxytocin
Correct Answer: A
Expert Explanation: Progesterone is often called the hormone of pregnancy
because it maintains the uterine lining for implantation. It is initially produced by
the corpus luteum and later by the placenta. Progesterone also helps prevent
uterine contractions that could lead to miscarriage.
