A multigravida who is 34 weeks gestation wants to know at what level her uterine fundus should be. The best answer is to advise
bixtya [17]

Answer: Her fundal height is 34 centimetres

Explanation:

A multigravada is a woman who has previously had at least two pregnancies. The fundus of the uterus is the top part of the uterus that is across from the cervix (opening of the uterus).

The level of the uterine fundus is referred to as the "fundal height". The fundal height is the distance from the pubic bone to the top of the uterus measured in centimetres. After 20 weeks of pregnancy, the fundal height most times matches the number of weeks one has been pregnant. In this case, since the multigravada is 34 weeks pregnant, her fundal height should be 34 centimetres.

However there are exceptions to this in cases of

▪obesity

▪fibroids

▪multiple births

Slow fetal growth, in balance in the amount of amniotic fluid, or a slightly larger than average baby can cause the fundal height measurement to be smaller or larger than expected.
