Urine output usually decreases when a person is in shock. This is the result of
A) decreased ADH secretion.
B) increased renin secretion.
C) increased secretion of atrial natriuretic factor.
D) decreased vasoconstriction due to the stress relaxation response.
E) decreased aldosterone secretion.

Question

Quizplus · Accepted Answer

Increased renin secretion is a response to decreased blood flow or blood pressure, common in shock. Renin leads to the production of angiotensin II, which promotes vasoconstriction and aldosterone secretion, ultimately conserving sodium and water to increase blood volume and improve blood pressure, but this can lead to decreased urine output.
