PNR 203/PNR203 Exam 1 V2 | Maternal-
Newborn Nursing Q&A with Rationale |
Fortis College
1. A nurse is calculating the estimated date of birth (EDB) for a client using Naegele’s rule. The
client’s last menstrual period began on May 10. Which of the following is the correct EDB?
A. February 3
B. February 10
C. March 10
D. February 17
Correct Answer: D
Expert Explanation: To calculate the EDB using Naegele’s rule, you subtract 3 months
from the first day of the last menstrual period and add 7 days. Starting from May 10,
subtracting 3 months brings you to February 10, and adding 7 days results in February 17.
This method assumes a standard 28-day cycle and is a primary tool used in prenatal
assessments.
2. A nurse is collecting data from a client who is at 12 weeks of gestation. Which of the
following findings should the nurse identify as a presumptive sign of pregnancy?
A. Positive pregnancy test
B. Goodell’s sign
,C. Fetal heart tones
D. Amenorrhea
Correct Answer: D
Expert Explanation: Presumptive signs are subjective changes felt by the woman, such as
amenorrhea, fatigue, and nausea. Probable signs, like a positive pregnancy test or Goodell’s
sign, are objective changes observed by an examiner but could have other causes. Positive
signs are definitive proof of pregnancy, such as hearing fetal heart tones or visualizing the
fetus via ultrasound.
3. A nurse is assessing a pregnant client’s GTPAL. The client is currently pregnant, had one
miscarriage at 10 weeks, and has one child born at 39 weeks. What is the correct GTPAL?
A. G3, T1, P0, A1, L1
B. G2, T1, P0, A1, L1
C. G3, T2, P0, A0, L1
D. G2, T0, P1, A1, L1
Correct Answer: A
Expert Explanation: The client is Gravida 3 (current pregnancy, one previous birth, one
miscarriage). Term is 1 (the child born at 39 weeks), Preterm is 0, Abortion is 1 (the
miscarriage at 10 weeks), and Living is 1. Accurate GTPAL documentation is essential for
determining the obstetric risk profile of the client.
, 4. Which hormone is primarily responsible for maintaining the endometrial lining during early
pregnancy until the placenta takes over?
A. Estrogen
B. Human Chorionic Gonadotropin (hCG)
C. Oxytocin
D. Progesterone
Correct Answer: D
Expert Explanation: Progesterone is often called the hormone of pregnancy because it
maintains the endometrium and prevents uterine contractions. Initially produced by the
corpus luteum, the placenta becomes the primary source after approximately 10 to 12
weeks. Deficiency in progesterone levels during early pregnancy can lead to spontaneous
abortion.
5. A nurse is teaching a client about nutrition during pregnancy. Which of the following
nutrients should the nurse instruct the client to increase to prevent neural tube defects?
A. Folic acid
B. Iron
C. Vitamin C
D. Calcium
Correct Answer: A
