QuestionChoice
This would effectively cause a low eGFR and therefore lead to an acute kidney injury (AKI).

e
Angiotensin II acts on afferent arterioles to cause vasoconstriction and prostaglandins act on efferent arterioles to cause vasodilation
QuestionChoice
Angiotensin II causes arterial vasoconstriction.

d
Angiotensin II acts on afferent and efferent arterioles to cause vasodilation
QuestionChoice
Angiotensin II is a vasoconstrictor whereas prostaglandins are vasodilators.

b
Angiotensin II acts on afferent arterioles to cause vasodilation and prostaglandins act on efferent arterioles to cause vasoconstriction
QuestionChoice
Prostaglandins are vasodilators.

c
Prostaglandins act on afferent and efferent arterioles to cause vasoconstriction
QuestionChoice
Prostaglandins are produced in response to stimulation of the sympathetic nervous system and cause smooth muscle relaxation, preferentially of the afferent arteriole wall. This causes vasodilation. Angiotensin acts on AT1 receptors to cause vasoconstriction. Both of these actions increase eGFR.
