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.

Explanation
Constipation is a common problem for clients who have recently given birth, and suppositories are a common treatment option for constipation. However, suppositories are not appropriate for all clients. Certain conditions can be a contraindication to the use of suppositories, and the nurse should be aware of these conditions.
The nurse should identify that a third-degree perineal laceration is a contraindication to the use of a suppository, as it may cause further trauma to the already injured area. In this case, alternative treatments such as stool softeners or oral laxatives may be more appropriate for the client.
Option A is incorrect because although abdominal distention can be a sign of constipation, it is not a contraindication to the use of a suppository.
Option C is also incorrect because vaginal candidiasis is not a contraindication to the use of a suppository. In fact, suppositories are sometimes used to treat vaginal candidiasis.
Option D is also incorrect because afterpains are not a contraindication to the use of a suppository.
Correct Answer is A
Explanation
Cytomegalovirus (CMV) is a common viral infection that can be transmitted from mother to newborn during childbirth. It can also be transmitted through contact with infected bodily fluids, including saliva, urine, and breast milk. Therefore, it is important to practice good hand hygiene and avoid sharing utensils or cups with young children who may be infected. Airborne precautions are not required for CMV, as it is not transmitted through the air. Prophylactic treatment with acyclovir is not effective against CMV, and there is no cure for the infection. Lesions are not typically visible on the mother's genitalia, and many mothers who are infected with CMV have no symptoms at all.
