a. Hypotension
b. Liver failure
c. Hypertension
d. Nasal congestion
ANS: C
Prazosin is a centrally acting sympatholytic that stimulates alpha receptors in the central nervous system to inhibit vasoconstriction, thus reducing peripheral resistance, which reduces blood pressure in hypertensive patients.
Prazosin, an adrenergic blocker, is used to treat hypertension, not hypotension.
Prazosin is contraindicated in patients with impaired liver function, and therefore would not be used for a patient in liver failure.
Prazosin is not used to relieve patients of nasal congestion.
