Exercise 44

Prerenal acute renal failure could be caused by:

A. Massive hemorrhage

B. Acute tubular necrosis

C. Acute interstitial nephritis

D. Malignant tumors

Step 1 of 2

Renal failure:

Kidney failure occurs both in acute and chronic forms

• Renal failure occurs gradually from a disorder to worsening of condition causing end stage renal disease or chronic renal failure.

Acute renal failure:

• It is contrast to chronic renal failure which exhibits sudden lack of renal function and it can be reversible.

Prerenal acute renal failure:

• Sudden decrease of blood flow to kidney.

• Kidney’s cannot remove waste products and excess fluid, which then stores in the body and upset chemical balance of the body.

Causes include,

• Low blood pressure or cardiac output

• Blood loss in major injury or surgery

• Hemorrhage

• Burns, surgery, septicemia.

Massive hemorrhage:

• Blood flow from ruptured vessel in the body.

• It can be external or internal blood flow.

Therefore, “massive hemorrhage” could be a cause for prerenal acute renal failure. Hence, the correct answer is option .
