Answer to Question 1

Correct Answer: 4
Rationale 1: An EpiPen should not be exposed to light, so it cannot be kept on counters.
Rationale 2: An EpiPen should be kept at room temperature. Refrigeration should be avoided.
Rationale 3: An EpiPen is sensitive to heat; it should be kept in a cool, dark place.
Rationale 4: An EpiPen is sensitive to light, and so should be kept in a cool, dark place.
Global Rationale: An EpiPen is sensitive to light and heat, and so should be kept in a cool, dark place. An EpiPen should be kept at room temperature. Refrigeration should be avoided.

Answer to Question 2

Correct Answer: 2
Rationale 1: Isoproterenol is not an alpha-2 receptor agonist. Alpha-2 receptor agonists are used for treatment of hypertension. They act through nonautonomic central mechanisms.
Rationale 2: Isoproterenol activates beta-1 receptors to increase the strength of myocardial contraction and improve cardiac output. This increases its potential for causing serious side effects.
Rationale 3: Isoproterenol has no effect on alpha-1 receptors. Alpha-1 receptor agonists are used for pharmacotherapy of nasal congestion and hypotension.
Rationale 4: Isoproterenol has no effect on dopaminergic receptors.
