Question 29 Sudden kidney failure occurs due to- A kidney stone B hypertension C diabetes D Severe blood loss

Sudden kidney failure, also known as acute renal failure, can occur due to several reasons. Here's a breakdown of the options:

A) Kidney Stone: While a kidney stone can cause pain and potential complications, it does not typically cause sudden kidney failure. However, if a stone blocks the flow of urine, it could potentially lead to kidney damage.

B) Hypertension: Chronic hypertension can lead to kidney damage over time, but it's not typically associated with sudden kidney failure.

C) Diabetes: Similar to hypertension, diabetes can cause kidney damage over time (diabetic nephropathy), but it's not usually a cause of sudden kidney failure.

D) Severe Blood Loss: Severe or rapid blood loss can lead to a sudden drop in blood pressure, which can in turn cause a reduction in blood flow to the kidneys. This can result in sudden kidney failure.

So, the most likely answer to this question would be D) Severe Blood Loss. However, it's important to note that many factors can contribute to sudden kidney failure, and it often results from a combination of issues.
