A pregnant client is prescribed 400mcg of folic acid daily to prevent neural tube defects. The available tablet contains 200mcg of folic acid per tablet. How many tablets should the client take per day?
1 mg
2 tablets
4 tablets
5mg
The Correct Answer is B
A. 1 mg:
1 mg = 1000 mcg, which is more than the prescribed 400 mcg.
B. 2 tablets:
Each tablet is 200 mcg; 2 tablets = 400 mcg, which meets the daily requirement.
C. 4 tablets:
Equals 800 mcg, which is double the prescribed dose.
D. 5 mg:
5 mg = 5000 mcg - far exceeds the recommended 400 mcg, unless there's a high-risk indication.

Correct Answer is D
Explanation
A. Uteroplacental insufficiency:
This typically causes late decelerations, not variable decelerations. Late decelerations occur after the peak of a contraction due to decreased placental perfusion.
B. Maternal hypotension:
This can cause late decelerations by reducing blood flow to the uterus and placenta, but does not typically cause variable decelerations.
C. Head compression:
This causes early decelerations, which mirror contractions, not variable decelerations.
D. Compression of the umbilical cord:
Variable decelerations are abrupt decreases in fetal heart rate and are most commonly caused by umbilical cord compression, which can occur during or between contractions.
