Answer to Question 1

Correct Answer: 3

Rationale 1: Beta 1 receptors are not stimulated in the treatment of asthma.
Rationale 2: Alpha 2 receptors are not stimulated in the treatment of asthma.
Rationale 3: Beta 2 receptors are stimulated in the treatment of asthma.
Rationale 4: Alpha 1 receptors are not stimulated in the treatment of asthma.

Global Rationale: Beta 2 receptors are stimulated in the treatment of asthma. Beta 1, Alpha 2 , Alpha 1 and receptors are not stimulated in the treatment of asthma.

Answer to Question 2

Correct Answer: 1

Rationale 1: Hypertension is treated with adrenergic blockers. Adrenergic blockers relax vascular smooth muscle in small arteries, causing vasodilation, which results in decreased blood pressure. Over-the-counter medications likely contain autonomic agents that can potentiate the effects of the adrenergic blocker, causing severe hypotension, dizziness, fainting, dry mouth, shortness of breath, palpitations, or chest pain.
Rationale 2: Adrenergic blockers are not used to treat severe colds, gastritis, or seizures.
Rationale 3: Adrenergic blockers are not used to treat severe colds, gastritis, or seizures.
Rationale 4: Adrenergic blockers are not used to treat severe colds, gastritis, or seizures.
