Which of the following factors could cause elevated BUN levels? A) Amino-acid supplementation B) Glomerular filtration dysfunction C) Reduced fluid intake D) Low protein diet
Understand the Problem
The question is asking which factors could lead to increased Blood Urea Nitrogen (BUN) levels in the body. To solve this, we need to analyze each option based on what is known about the causes of elevated BUN levels.
Answer
Glomerular filtration dysfunction and reduced fluid intake can cause elevated BUN levels.
Factors that can cause elevated BUN levels include glomerular filtration dysfunction (B), reduced fluid intake (C), and a high protein diet. Low protein diet is associated with lowered BUN levels.
Answer for screen readers
Factors that can cause elevated BUN levels include glomerular filtration dysfunction (B), reduced fluid intake (C), and a high protein diet. Low protein diet is associated with lowered BUN levels.
More Information
Elevated BUN levels are typically linked to impaired renal function or dehydration, as both conditions can lead to reduced clearance of urea from the body.
Tips
A common mistake is to assume that a low protein diet increases BUN levels; however, it is actually high protein intake or impaired kidney function that elevates BUN.
