Certified Midwife Exam Prep Antepartum Care & Prenatal Assessment

Question 1

At what gestational age is a first-trimester ultrasound most accurate for dating a pregnancy?

Accepted Answer

11–14 weeks

Answer

An ultrasound at 11–14 weeks provides the most accurate gestational dating due to the predictable size of the fetus at that stage.

Question 2

Which lab value is routinely checked at the initial prenatal visit to screen for anemia in pregnant patients?

Accepted Answer

Complete blood count (CBC)

Answer

A CBC is obtained at the first prenatal visit to establish baseline hemoglobin and hematocrit and screen for anemia.

Question 3

A certified midwife is counseling a patient at 16 weeks gestation. Which screening test is typically offered between 15–20 weeks?

Accepted Answer

Quad screen

Answer

The quad screen (AFP, hCG, estriol, inhibin A) is a second-trimester maternal serum screen offered between 15–20 weeks.

Question 4

Which finding on fundal height measurement at 28 weeks would prompt further evaluation?

Accepted Answer

22 cm

Answer

Fundal height more than 3 cm below expected gestational age (i.e., ≤25 cm at 28 weeks) suggests intrauterine growth restriction and warrants ultrasound.

0.4 mg

Answer

The standard recommendation for low-risk pregnancies is 0.4 mg (400 mcg) of folic acid daily, ideally starting before conception.
