Correct Answer is B

Explanation

A. Hypernatremia is usually due to an excess of sodium or a deficit of water, not directly related to prerenal causes.
B. Prerenal AKI is characterized by a decrease in renal blood flow, which leads to a reduction in glomerular filtration rate and a subsequent accumulation of waste products, including potassium. Hyperkalemia occurs because the kidneys are unable to excrete potassium effectively.
C. Hypercalcemia is not typically associated with AKI.
D. Hypophosphatemia is generally associated with malnutrition or malabsorption syndromes and is not a direct result of prerenal AKI.

A. Ondansetron B. Diphenhydramine C. Vancomycin D. Omeprazole

C. Vancomycin is an antibiotic that can cause nephrotoxicity, especially when administered in high doses or in individuals with impaired renal function. Monitoring renal function is crucial when using vancomycin.
