Answer to Question 1
Correct Answer: 3,4
Rationale 1: Propranolol can be used in cases of angina, although this drug is less frequently used than are the cardioselective drugs.
Rationale 2: Propranolol can be used as an antidysrhythmic since it is most effective against tachycardia caused by excessive sympathetic stimulation.
Rationale 3: Propranolol increases serum triglycerides and decreases high-density lipoproteins. Patients with preexisting hyperlipidemia should have their lipid profiles monitored periodically to prevent hyperlipidemia.
Rationale 4: Propranolol is nonselective beta blocker and can block the beta2 receptors in the lung, which can be dangerous in case of asthma.
Rationale 5: This medication is not contraindicated for use in liver failure.

Answer to Question 2
Correct Answer: 4
Rationale 1: Carvedilol (Coreg) is classified as a nonselective beta blocker, blocking both the beta1 and beta2 receptors as well as the alpha1 receptors and not just the beta2 receptors.
Rationale 2: Carvedilol (Coreg) is classified as a nonselective beta blocker, blocking both the beta1 and beta2 receptors as well as the alpha1 receptors, not just the beta receptors.
Rationale 3: Carvedilol (Coreg) is classified as a nonselective beta blocker, blocking both the beta1 and beta2 receptors as well as the alpha1 receptors, not just the beta1 receptors.
Rationale 4: Carvedilol (Coreg) is classified as a nonselective beta blocker, blocking both the beta1 and beta2 receptors as well as the alpha1 receptors. The dizziness and faintness are due to its effect on all of these receptors.
