Answer to Question 1

d

Answer to Question 2

A
Metoprolol is preferred to the nonselective beta blockers for patients with asthma or diabetes.
Propranolol can cause blockade of beta2 receptors in the lungs, causing bronchoconstriction; it therefore is not recommended for patients with asthma.
Pindolol can cause blockade of beta2 receptors in the lungs, causing bronchoconstriction; it therefore is not recommended for patients with asthma.
Carteolol can cause blockade of beta2 receptors in the lungs, causing bronchoconstriction; it therefore is not recommended for patients with asthma.
