A nurse is reviewing the BUN result of a client who is taking cyclosporine following a kidney transplant. Which of the following laboratory studies should the nurse recognize as another renal function study that should be monitored?

Rationale:
A. Administer betamethasone to the client: Betamethasone is given to promote fetal lung maturity in preterm labor, typically before 34 weeks of gestation. At 37 weeks, the fetus is considered term, so corticosteroids are not indicated.

B. Administer magnesium sulfate to the client: Magnesium sulfate is used for neuroprotection in preterm labor or for seizure prophylaxis in preeclampsia. Since this client is at term without preeclampsia, magnesium sulfate is not indicated.

C. Monitor fetal heart rate every 4 hr: Continuous or frequent fetal heart rate monitoring is recommended after spontaneous rupture of membranes to detect signs of fetal distress or infection. Monitoring only every 4 hours is insufficient.

D. Monitor the client's temperature every 2 hr: Maternal infection, such as chorioamnionitis, is a significant risk after spontaneous rupture of membranes. Monitoring the client’s temperature every 2 hours allows early detection of infection and timely intervention.

Rationale:
A. "Take a stool softener daily.": Preventing straining during bowel movements is critical after retinal surgery because increased intraocular pressure from straining can disrupt the surgical repair. Stool softeners help maintain soft stools and reduce the risk of increased eye pressure.

B. "You can lift objects that weigh 15 pounds.": Clients should avoid heavy lifting after retinal surgery to prevent increased intraocular pressure. The amount of weight considered safe is minimal, and lifting anything heavier can compromise the surgical site.

C. "Avoid reading for 3 days following surgery.": Light visual activities like reading are usually permitted after surgery, depending on provider instructions. Complete restriction is unnecessary, though clients should avoid activities that increase eye strain or involve prolonged downward gaze.

D. "Pick up items by bending at the waist.": Bending at the waist increases intraocular pressure, which can compromise the retina. Clients should be instructed to bend at the knees and keep the head upright when picking up objects to protect the surgical repair.
