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. Diabetes mellitus: Diabetes is not a direct contraindication or risk factor for complications from electroconvulsive therapy (ECT). Blood glucose should be monitored, but it does not increase procedural risk.

B. Subdural hematoma: A subdural hematoma increases the risk of complications during ECT because the induced seizure can elevate intracranial pressure, potentially worsening the hematoma or causing neurological deterioration. This is a significant safety consideration.

C. Hyperthyroidism: While hyperthyroidism can affect cardiovascular response, it is not as high-risk as intracranial pathology. Pre-procedure assessment may include thyroid function evaluation if indicated.

D. Renal calculi: Kidney stones do not increase the risk of ECT complications. This condition is unrelated to seizure induction or anesthetic considerations.

Rationale:
A. "Store and eat luncheon deli meats cold while pregnant.": Cold deli meats can harbor Listeria monocytogenes, which can cause listeriosis and increase the risk of miscarriage or fetal infection. Pregnant clients should heat deli meats until steaming before consumption to reduce this risk.

B. "Wash all fruits thoroughly before consumption during pregnancy.": Washing fruits removes dirt, bacteria, and potential contaminants such as Listeria or Toxoplasma, reducing the risk of food-borne illness. This is a key preventive measure for maintaining maternal and fetal health.

C. "Consumption of raw fish is safe during pregnancy if done in moderation.": Raw fish can contain parasites and bacteria such as Salmonella, or Toxoplasma. Pregnant clients should avoid raw or undercooked fish entirely to prevent serious infections that can harm the fetus.

D. "Food-borne illnesses are more difficult to contract while pregnant.": Pregnancy actually increases susceptibility to certain food-borne illnesses due to immunologic changes. Pregnant clients should follow strict food safety measures to protect both maternal and fetal health.
