If a patient experiences acute renal failure, which consequence follows from a reduction in glomerular filtration rate and impaired electrolyte regulation?

💡 Explanation

In acute renal failure, the kidneys' ability to filter blood and regulate electrolytes is compromised; because the glomerular filtration rate decreases and electrolyte balance is disrupted, potassium accumulates, and acid excretion declines. Therefore, hyperkalemia and metabolic acidosis develop, rather than immediate changes in erythropoietin or parathyroid hormone levels, or increased phosphate excretion.
