Question

When is the MacDonald maneuver for fundal height most reliable?

a) 12 weeks
b) 20 weeks
c) 28 weeks
d) 36 weeks

Answer 1

The MacDonald maneuver for fundal height is most reliable at 28 weeks of gestation when the uterus is sufficiently large to provide an accurate measurement.

Step-by-step explanation:

The MacDonald maneuver is a technique used to measure the fundal height during pregnancy to assess fetal growth and estimate gestational age. The most reliable time to perform the MacDonald maneuver is at 28 weeks of gestation. Prior to this, the uterus is typically not large enough to provide an accurate measurement of the fundal height. By 28 weeks, the fundal height in centimeters often corresponds closely to the number of weeks of pregnancy, which is why this time frame provides a more reliable measurement.
