A nurse is providing teaching about the expected effects of magnesium sulfate to a client who is at 28 weeks of gestation and has preeclampsia. Which of the following responses by the nurse is appropriate?
"This medication stabilizes the fetal heart rate."
"This medication prevents seizures."
"This medication increases cardiac output."
This medication improves tissue perfusion."
The Correct Answer is B
Magnesium sulfate is used to prevent seizures in clients with preeclampsia. It works by relaxing the smooth muscles and blocking neuromuscular transmission. While magnesium sulfate can indirectly improve fetal heart rate and tissue perfusion by preventing seizures, it does not directly stabilize the fetal heart rate or increase cardiac output.

Correct Answer is D
Explanation
The nonstress test is a screening tool that assesses fetal well-being. It is performed by monitoring the fetal heart rate (FHR) and uterine contractions (UC) while the client is at rest. The test is considered reactive if there are two or more accelerations of the FHR that reach a certain level above the baseline and last for at least 15 seconds over a 20-min period.
The presence of irregular contractions that are not felt by the client is a finding that is concerning because it could be a sign of uterine hyperstimulation, which can lead to fetal distress. Further diagnostic testing may be needed to assess fetal well-being in this situation.
Option A indicates that the client felt fetal movements during the testing period. This is a reassuring finding because fetal movements are a sign of fetal well-being.
Option B indicates that there were no late decelerations in the FHR with uterine contractions. This is a reassuring finding because late decelerations are a sign of fetal compromise.
Option C indicates that there was an acceleration of the FHR in response to fetal movement. This is a reassuring finding because it indicates that the fetus is capable of responding to stimuli.
Correct Answer is C
Explanation
The purpose of bathing the newborn before initiating skin-to-skin contact is to decrease the risk of transmission of the virus from the mother to the newborn. Instructing the client to stop taking the antiretroviral medications at 32 weeks of gestation is incorrect as these medications should be taken throughout pregnancy to decrease the risk of transmission to the fetus.
Using a fetalscalp electrode during labor and delivery is also not an appropriate action as it increases the risk of transmission of the virus to the newborn. Administering a pneumococcal immunization to the newborn within 4 hours following birth is not specific to HIV positive newborns and is not related to preventing transmission of the virus.
