Which method provides the most accurate estimation of gestational age when the pregnancy is dated early?
Correct answer: B. First trimester ultrasound
- A. Maternal weight at booking
- B. First trimester ultrasound
- C. Time of first fetal movement
- D. Fundal height near term
Explanation
First trimester ultrasound, especially measurement of the crown-rump length, provides the most reliable early dating. Maternal perception of movement and late fundal height are less precise for calculating gestational age.
