Question

Elevated levels of urea that are seen with reduced renal perfusion, high protein diet, fever, and/or hemorrhage have to do with which of the following:

a) Pre-renal
b) Renal
c) Post-renal
d) None of the above

Answer 1

Elevated levels of urea in relation to reduced renal perfusion, among other factors, are linked to a) pre-renal causes which precede kidney damage.

Step-by-step explanation:

Elevated levels of urea that are seen with reduced renal perfusion, high protein diet, fever, and/or hemorrhage are associated with pre-renal factors. The term pre-renal uremia refers to an increase in blood urea level due to conditions that affect the blood supply before it reaches the kidneys. These can include factors like dehydration from vomiting or diarrhea, which leads to hemoconcentration and low blood pressure, thereby reducing the glomerular filtration rate and raising the urea levels in the blood.
