C)cause oliguria.
D)cause hematuria.

Question

Quizplus · Accepted Answer

A sudden decline in blood pressure to 80/45 mm Hg is likely to cause oliguria, which is a decrease in urine output. This is because low blood pressure reduces the perfusion pressure in the renal arteries, decreasing the glomerular filtration rate (GFR) and the urine output. This reduced GFR can also cause azotemia, which is an increase in the blood levels of nitrogenous waste products. Hematuria is unlikely to be caused by a sudden drop in blood pressure.
