Correct Answer is C
Explanation
A. Hypomagnesemia: Magnesium levels are typically elevated in AKI due to reduced excretion.
B. Decreased creatinine level: Creatinine rises during the oliguric phase due to decreased filtration.
C. Hyperkalemia: Potassium accumulates in the blood during oliguria due to impaired excretion.
D. Increased glomerular filtration rate (GFR): GFR is decreased in AKI.
Correct Answer is A
Explanation
A. Hyperkalemia: In AKI, the kidneys cannot excrete potassium efficiently, leading to elevated potassium levels.
B. Hypernatremia: More common in dehydration but not typically associated with prerenal AKI, where sodium may actually be low due to dilution.
C. Hypophosphatemia: Phosphate tends to increase due to impaired excretion in AKI, not decrease.
D. Hypercalcemia: Calcium levels tend to decrease in AKI due to phosphate retention and reduced vitamin D activation.
