A patient who has been treated with hydralazine (Apresoline) is also taking propranolol (Inderal). The nurse understands that the rationale for this concurrent use of the two medications is to
a. prevent rebound hypertension.
b. prevent reflex tachycardia.
c. reduce afterload to prevent heart failure.
d. prevent a drug-induced lupus erythematosus–type reaction.
ANS: B
Propranolol is a beta blocker, which is used concurrently with hydralazine to prevent reflex tachycardia, which is common with the use of hydralazine.
Propranolol will not prevent rebound hypertension with hydralazine.
Isosorbide dinitrate (Isordil) would be used to reduce afterload.
Beta blockers do not prevent a drug-induced lupus erythematosus–type reaction.
