Question

The nurse finds that a patient has a blood pressure of 140/90 mm hg and has constricted bronchioles. which drug regimen will ensure the patient's safety?

Answer 1

There are choices for this question namely:

Carvedilol
Betaxolol
Acebutolol
Propranolol
Metoprolol

The correct answers are "betaxolol", "acebutolol",and "metoprolol". These drugs are from the class called beta blockers as they inhibition the action of beta receptors in the heart leading to a decrease in heart rate and blood pressure. There are also beta receptors in the bronchial tree, an inhibition of which will lead to bronchoconstriction.

Betaxolol, acebutolol, and metoprolol are cardioselective beta blockers and only blocks the beta receptors located in the heart. Carvedilol and propranolol are non-selective beta blockers that can cause bronchoconstriction which is contraindicated in patients with asthma.
