12 weeks
- The patient most likely became pregnant about 20 weeks ago.
- Fundal height measurements can be used to estimate gestational.
- Fundal height is measured in centimeters from the top of the pubic bone.
- At 12 weeks' gestation the fundal height is located at the level of the pubic symphysis.
- At 16 weeks' gestation the fundal height is measured halfway between the pubic symphysis and the umbilicus.
- At 20 weeks' gestation the fundus of the uterus is located at approximately the level of the umbilicus.
- Many disorders of pregnancy can lead to inaccurate fundal height measurements.
- If an ultrasound confirms the gestation length and the fundal height does not correspond further testing should be initiated.
- Answers 1/2: The uterus cannot be palpated until 12 weeks' gestation.
