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. Decreased serum uric acid: In preeclampsia, serum uric acid levels are elevated, not decreased, due to reduced renal clearance and tissue ischemia. Increased uric acid is often one of the earliest laboratory indicators of preeclampsia.

B. Increased protein in urine: Proteinuria is a key diagnostic feature of preeclampsia resulting from glomerular endothelial damage that increases permeability to proteins. The presence of protein in the urine reflects kidney involvement and helps distinguish preeclampsia from gestational hypertension.

C. Increased platelet count: Preeclampsia is typically associated with thrombocytopenia (low platelet count) due to platelet aggregation and consumption within damaged blood vessels. An increased platelet count would not be expected in this condition.

D. Decreased BUN: In preeclampsia, renal perfusion is reduced, leading to elevated BUN and creatinine levels. A decrease in BUN would indicate improved kidney function, which is inconsistent with the pathophysiology of preeclampsia.

Rationale:
A. "I will remove gluten from my diet.": Gluten is not associated with latex cross-reactivity. Gluten sensitivity is related to celiac disease, which involves an immune response to wheat proteins, not latex allergens.

B. "I will remove peanuts from my diet.": Peanuts are not part of the common cross-reactive foods for latex allergy. While peanuts are a frequent cause of food allergies, they do not share similar protein structures with latex that trigger cross-sensitivity reactions.

C. "I will remove bananas from my diet.": Bananas share similar protein allergens with natural rubber latex, which can trigger cross-reactive allergic responses. Individuals with latex allergy often react to foods such as bananas, avocados, kiwis, and chestnuts, making avoidance of these foods advisable.

D. "I will remove dairy products from my diet.": Dairy products do not have protein structures similar to those found in latex and are not linked to latex-related cross-reactivity. Removing them from the diet provides no benefit in managing latex allergies.
