Nurse Q&A with Rationale | Hondros
College of Nursing
1. A pregnant patient reports that her last menstrual period (LMP) began on May 10th. Using
Nagele’s rule, what is her estimated date of delivery (EDD)?
A. February 3rd of the following year
B. February 17th of the following year
C. August 17th of the following year
D. February 10th of the following year
Correct Answer: B
Rationale: To calculate the EDD using Nagele’s rule, the nurse should subtract 3 months
from the first day of the LMP and add 7 days. Starting from May 10, subtracting 3 months
leads to February 10, and adding 7 days results in February 17. This method assumes a
standard 28-day menstrual cycle and is a common assessment tool in prenatal care.
2. Which of the following findings is considered a ‘positive’ sign of pregnancy?
A. Amenorrhea
B. Positive serum pregnancy test
C. Fetal heart tones heard via Doppler
,D. Chadwick’s sign
Correct Answer: C
Rationale: Positive signs of pregnancy are those that can only be attributed to the
presence of a fetus. These include fetal heart tones, visualization of the fetus by ultrasound,
and fetal movement felt by a trained clinician. Signs like amenorrhea are presumptive, and
positive lab tests are only considered probable signs.
3. A nurse is teaching a pregnant woman about the importance of folic acid. Which condition
is primarily prevented by adequate folic acid intake?
A. Gestational Diabetes
B. Fetal Macrosomia
C. Neural tube defects
D. Down Syndrome
Correct Answer: C
Rationale: Folic acid is essential for DNA synthesis and the proper closure of the neural
tube in the early weeks of gestation. Deficiency in this nutrient can lead to serious
malformations such as spina bifida or anencephaly. The recommended daily intake for
most pregnant women is 400 to 800 mcg.
4. During a prenatal visit, a patient at 20 weeks gestation reports feeling dizzy when lying flat
on her back. Which action should the nurse recommend?
A. Drink a glass of orange juice immediately
, B. Take a deep breath and hold it for ten seconds
C. Lie on the left side with a pillow under the hip
D. Schedule an emergency ultrasound
Correct Answer: C
Rationale: This condition is known as supine hypotensive syndrome, caused by the heavy
uterus compressing the inferior vena cava. Compression reduces blood return to the heart,
leading to a drop in cardiac output and maternal blood pressure. Turning the patient onto
her side, especially the left side, relieves the pressure and restores circulation.
5. What is the primary function of the placenta during pregnancy?
A. To serve as a physical barrier against all medications
B. To provide metabolic exchange for nutrients and waste
C. To stimulate uterine contractions
D. To regulate the mother’s blood sugar levels
Correct Answer: B
Rationale: The placenta acts as the interface between maternal and fetal circulation,
facilitating the transport of oxygen and nutrients to the fetus. It also removes waste
products such as carbon dioxide and urea from the fetal bloodstream. Furthermore, the
placenta produces hormones like hCG and progesterone to maintain the pregnancy.
