A woman is 36 weeks’ gestation. Which of the following tests will be done during her prenatal visit?
- A. Glucose challenge test.
- B. Amniotic fluid volume assessment.
- C. Vaginal and rectal cultures.
- D. Karyotype analysis.
Correct Answer: C
Rationale: Vaginal and rectal cultures are performed to check for Group B Streptococcus (GBS), which can affect the newborn. Glucose challenge tests are typically done earlier in pregnancy, and karyotype analysis is not routine.
A pregnant patient at 24 weeks gestation is concerned about gestational diabetes. Which of the following is the most important aspect of managing this condition?
- A. Increasing physical activity and monitoring blood glucose levels.
- B. Administering insulin to control blood sugar levels.
- C. Eating larger meals to prevent hypoglycemia.
- D. Limiting fluid intake to reduce blood sugar fluctuations.
Correct Answer: A
Rationale: The correct answer is A: Increasing physical activity and monitoring blood glucose levels. This is because physical activity helps improve insulin sensitivity and manage blood glucose levels in gestational diabetes. Monitoring blood glucose levels is essential to ensure they are within the target range for both the mother and baby's health. Administering insulin (B) may be necessary in some cases but is not the first-line approach. Eating larger meals (C) can lead to higher blood sugar levels and does not prevent hypoglycemia. Limiting fluid intake (D) is not recommended as it can lead to dehydration and does not directly impact blood sugar fluctuations.

- B. June 20, 2013.
- C. June 27, 2013.
- D. July 3, 2013.
Correct Answer: C
Rationale: Using Nagele’s rule (adding 7 days to the first day of the last menstrual period, subtracting 3 months, and adding 1 year), the calculated EDD is June 27, 2013.
What is the primary benefit of delayed cord clamping in a term newborn?
- A. increased hemoglobin levels
- B. improved thermoregulation
- C. decreased risk of bleeding
- D. increased risk of infection
Correct Answer: B
Rationale: The primary benefit of delayed cord clamping in a term newborn is improved thermoregulation. When the cord is clamped later, it allows more blood to flow from the placenta to the baby, aiding in temperature stabilization. This helps prevent hypothermia, a common issue in newborns. Increased hemoglobin levels (choice A) are not the primary benefit of delayed cord clamping. Decreased risk of bleeding (choice C) is not directly related to delayed cord clamping. Increased risk of infection (choice D) is incorrect as delayed cord clamping does not increase the risk of infection.
