What is a poor prognostic factor indicated by increased BUN levels?
Understand the Problem
The question is asking to identify which condition is indicated as a poor prognostic factor associated with elevated blood urea nitrogen (BUN) levels among the given options.
Answer
An increased BUN level is a poor prognostic factor for heart failure, aortic dissection, peripheral artery disease, acute necrotizing pancreatitis, and hospital-acquired pneumonia.
An increased BUN level is a poor prognostic factor in conditions such as heart failure, aortic dissection, peripheral artery disease, acute necrotizing pancreatitis, and hospital-acquired pneumonia. It is associated with higher mortality in critically ill patients, independent of serum creatinine.
Answer for screen readers
An increased BUN level is a poor prognostic factor in conditions such as heart failure, aortic dissection, peripheral artery disease, acute necrotizing pancreatitis, and hospital-acquired pneumonia. It is associated with higher mortality in critically ill patients, independent of serum creatinine.
More Information
Increased BUN levels can indicate kidney impairment, but they are particularly concerning when indicating poor prognosis in conditions affecting the heart and circulation. Monitoring BUN levels can help predict mortality risks, especially in heart failure patients.
Tips
A common mistake is to consider only kidney function when interpreting BUN levels, ignoring their significance in evaluating prognosis in other critical conditions.
