At what gestational age is a first-trimester ultrasound most accurate for dating a pregnancy?
Answer: 11–14 weeks
An ultrasound at 11–14 weeks provides the most accurate gestational dating due to the predictable size of the fetus at that stage.
Which lab value is routinely checked at the initial prenatal visit to screen for anemia in pregnant patients?
Answer: Complete blood count (CBC)
A CBC is obtained at the first prenatal visit to establish baseline hemoglobin and hematocrit and screen for anemia.
A certified midwife is counseling a patient at 16 weeks gestation. Which screening test is typically offered between 15–20 weeks?
Answer: Quad screen
The quad screen (AFP, hCG, estriol, inhibin A) is a second-trimester maternal serum screen offered between 15–20 weeks.
Which finding on fundal height measurement at 28 weeks would prompt further evaluation?
Answer: 22 cm
Fundal height more than 3 cm below expected gestational age (i.e., ≤25 cm at 28 weeks) suggests intrauterine growth restriction and warrants ultrasound.
What is the recommended daily folic acid supplementation dose for a low-risk pregnant patient to prevent neural tube defects?
Answer: 0.4 mg
The standard recommendation for low-risk pregnancies is 0.4 mg (400 mcg) of folic acid daily, ideally starting before conception.
