Question

What are 3 pathophysiological causes of acute renal failure?

a. Dehydration, hyperkalemia, and acidosis

b. Infection, inflammation, and edema

c. Hypotension, nephrotoxic drugs, and obstruction

d. Hypernatremia, hypovolemia, and alkalosis

Answer 1

Three pathophysiological causes of acute renal failure are hypotension, nephrotoxic drugs, and obstruction.

Step-by-step explanation:

Acute renal failure is a condition characterized by a rapid loss of renal function. There are several pathophysiological causes of acute renal failure, but three common ones are:

1. Hypotension: Low blood pressure can reduce the blood supply to the kidneys, leading to kidney damage and acute renal failure.
2. Nephrotoxic drugs: Certain medications, such as nonsteroidal anti-inflammatory drugs (NSAIDs) and some antibiotics, can cause direct damage to the kidneys and result in acute renal failure.
3. Obstruction: When there is a blockage in the urinary tract, such as kidney stones or an enlarged prostate, it can prevent the normal flow of urine and lead to acute renal failure.
