NCLEX Prenatal Care Practice Questions with Answers

Prenatal care involves the comprehensive medical and nursing management of a pregnant woman from conception until the onset of labor to ensure the health of both the mother and the fetus. Mastering this topic is essential for nursing students, as it represents a significant portion of the maternal-newborn content on the licensure exam. This guide provides a detailed review of NCLEX Prenatal Care concepts, including physiological changes, diagnostic testing, and nutritional requirements.

Concept Explanation

NCLEX Prenatal Care focuses on monitoring the progression of pregnancy, identifying potential complications early, and providing education to promote optimal maternal and fetal outcomes. It encompasses the systematic assessment of a client throughout three trimesters, beginning with the confirmation of pregnancy via human chorionic gonadotropin (hCG) levels. Key components include calculating the estimated date of birth (EDB) using Naegele’s rule, assessing fetal heart tones, and monitoring fundal height. Nurses must also distinguish between presumptive, probable, and positive signs of pregnancy. For example, while amenorrhea is a presumptive sign, hearing fetal heart sounds is a positive sign. Understanding these distinctions helps in prioritizing care, similar to how one might prioritize tasks in Hard NCLEX Med Surg Practice Questions. Furthermore, prenatal care involves screening for conditions like gestational diabetes and preeclampsia, which require vigilant nursing interventions and client teaching regarding danger signs like vaginal bleeding or severe frontal headaches.

Solved Examples

1. Calculating the Estimated Date of Birth (EDB)
   A client informs the nurse that her last menstrual period (LMP) began on March 10. Using Naegele's rule, what is the EDB?
   1. Identify the first day of the LMP: March 10.
   2. Subtract 3 months from the month: March (3) - 3 = December (12).
   3. Add 7 days to the day: 10 + 7 = 17.
   4. Adjust the year if necessary. The EDB is December 17.
2. Interpreting GTPAL
   A woman is currently 20 weeks pregnant. She has a 3-year-old child born at 39 weeks, a 5-year-old child born at 34 weeks, and had one miscarriage at 10 weeks. Calculate her GTPAL.
   1. Gravida (G): Total pregnancies including current = 4.
   2. Term (T): Births at 37 weeks or more = 1 (the 3-year-old).
   3. Preterm (P): Births from 20 to 36.6 weeks = 1 (the 5-year-old).
   4. Abortion (A): Pregnancies ending before 20 weeks = 1 (miscarriage).
   5. Living (L): Number of living children = 2.
   6. Result: G4, T1, P1, A1, L2.
3. Fundal Height Assessment
   A nurse measures the fundal height of a client at 24 weeks gestation. Where should the fundus be located?
   1. Recall that after 20 weeks, the fundal height in centimeters usually matches the weeks of gestation $\pm 2 \text{ cm}$.
   2. At 20 weeks, the fundus is typically at the umbilicus.
   3. At 24 weeks, the fundus should be approximately 24 cm from the symphysis pubis, which is slightly above the umbilicus.

Practice Questions

1. A client at 12 weeks gestation complains of severe nausea and vomiting. Which laboratory finding would most likely indicate hyperemesis gravidarum rather than typical morning sickness?

2. During a prenatal visit, a nurse is teaching a pregnant client about nutrition. The client has a pre-pregnancy BMI of $22 \text{ kg/m}^2$. How much total weight gain should the nurse recommend for this pregnancy?

3. A nurse is reviewing the records of a client at 28 weeks gestation. Which immunization is specifically recommended during the third trimester to provide passive immunity to the newborn?

4. A nurse is assessing a client in the second trimester. Which of the following findings is considered a "positive" sign of pregnancy?

5. A pregnant client's screening results show she is Rh-negative. At which gestational age should the nurse expect to administer Rho(D) immune globulin if the client has no antibodies?

6. A client at 34 weeks gestation reports a sudden gush of clear fluid from the vagina. What is the priority nursing action?

7. The nurse is performing Leopold maneuvers. What is the primary purpose of this assessment during the late third trimester?

8. A client at 36 weeks gestation is diagnosed with mild preeclampsia. Which instruction should the nurse include in the home care teaching plan?

9. A nurse is educating a client about the "kick count" procedure. Which statement by the client indicates a need for further teaching?

10. Which nutritional supplement is most critical in the first trimester to prevent neural tube defects such as spina bifida?

Answers & Explanations

1. Ketonuria. While morning sickness is common, hyperemesis gravidarum involves persistent vomiting leading to dehydration, electrolyte imbalances, and ketonuria. The presence of ketones in the urine indicates the body is breaking down fat for energy due to starvation.
2. 25 to 35 pounds (11.5 to 16 kg). For a woman with a normal BMI (18.5–24.9), the CDC recommends a total weight gain of 25–35 lbs. Proper weight management is as vital as monitoring status in Hard NCLEX Renal Practice Questions.
3. Tdap (Tetanus, Diphtheria, and Pertussis). The Tdap vaccine is recommended between 27 and 36 weeks of pregnancy to optimize the transfer of maternal antibodies to the fetus, protecting the infant from pertussis (whooping cough) after birth.
4. Fetal heart tones heard by Doppler. Positive signs are those that can only be attributed to a fetus: fetal heart sounds, visualization of the fetus via ultrasound, or fetal movement felt by an experienced examiner. Amenorrhea and breast changes are presumptive.
5. 28 weeks gestation. Rho(D) immune globulin is typically administered to Rh-negative, unsensitized mothers at 28 weeks and again within 72 hours after delivery if the infant is Rh-positive.
6. Assess the fetal heart rate (FHR). A sudden gush of fluid suggests premature rupture of membranes. The immediate priority is to check the FHR to ensure there is no umbilical cord prolapse, which is a life-threatening emergency for the fetus.
7. To determine fetal presentation and position. Leopold maneuvers are a non-invasive way to palpate the abdomen to identify the fetal part in the fundus, the location of the fetal back, and the presenting part.
8. Monitor for headaches or visual disturbances. Mild preeclampsia management at home involves frequent monitoring for worsening symptoms (CNS irritability), which could indicate progression to severe preeclampsia or eclampsia.
9. "I should only call the doctor if I feel no movement for a whole day." This is incorrect. Clients should report if they feel fewer than 10 movements in a 2-hour period (or as directed by their provider) or if there is a significant decrease in the usual activity level.
10. Folic Acid (Vitamin B9). Adequate intake of folic acid (400–800 mcg daily) before and during early pregnancy is essential to ensure proper closure of the neural tube. Nurses often use tools like the AI Flashcard Generator to memorize these vital vitamin requirements.

1. Which of the following is a presumptive sign of pregnancy?

• AFetal heart rate detected by ultrasound
• BPositive pregnancy test
• CAmenorrhea
• DGoodell's sign

Frequently Asked Questions

What is the difference between presumptive and probable signs of pregnancy?

Presumptive signs are subjective changes felt by the woman, such as fatigue or nausea, while probable signs are objective changes observed by an examiner, such as a positive pregnancy test or cervical softening.

How often are prenatal visits scheduled for a low-risk pregnancy?

Standard scheduling involves monthly visits until 28 weeks, every two weeks from 28 to 36 weeks, and weekly visits from 36 weeks until birth.

What is the significance of the Group B Streptococcus (GBS) test?

GBS is a common bacterium that can be passed to the baby during delivery; if the mother tests positive at 35-37 weeks, she receives prophylactic antibiotics during labor to prevent neonatal sepsis.

Why is the left-lateral position recommended for pregnant women?

This position prevents the heavy uterus from compressing the inferior vena cava, which ensures optimal blood return to the heart and maintains placental perfusion.

What are the "danger signs" in the second and third trimesters?

Danger signs include vaginal bleeding, leakage of fluid, severe swelling of the face or hands, persistent headaches, visual blurs, and a significant decrease in fetal movement.

How is fundal height used to assess fetal growth?

Fundal height is measured in centimeters from the symphysis pubis to the top of the fundus; it should roughly equal the weeks of gestation between 18 and 32 weeks.
