A nurse in the emergency department is caring for a client who collapsed after playing football on a hot day. After reviewing the admission laboratory findings

The correct answer is C: Low-protein diet. The elevated BUN (blood urea nitrogen) and creatinine levels indicate impaired kidney function. In cases of kidney dysfunction, especially chronic kidney disease, a low-protein diet is often recommended to reduce the workload on the kidneys and prevent further damage. This diet helps to minimize the accumulation of waste products like urea and creatinine in the blood. The electrolyte values (sodium, potassium, chloride) and glucose level are within normal range, ruling out conditions like dehydration, SIADH, or renal failure. Therefore, the most likely explanation for the laboratory findings in this scenario is a low-protein diet contributing to the elevated BUN and creatinine levels.
