Answer to Question 1

Correct Answer: 2
Rationale 1: Isoproterenol does not affect alpha-1 receptors.
Rationale 2: Isoproterenol affects beta-1 and beta-2 receptors.
Rationale 3: Isoproterenol does not affect alpha-2 receptors.
Rationale 4: Isoproterenol does not affect all receptors.
Global Rationale: Isoproterenol affects beta-1 and beta-2 receptors. Isoproterenol does not affect alpha-1 receptors, beta-1 and beta-2 receptors, or all receptors.

Answer to Question 2

Correct Answer: 2
Rationale 1: Diarrhea is not an affect of muscarinic antagonists.
Rationale 2: Muscarinic antagonists are prescribed to reduce the muscular tremor and rigidity associated with Parkinson disease.
Rationale 3: Increased urine output is not an effect of muscarinic antagonists.
Rationale 4: Rhinorrhea is not an affect of muscarinic antagonists.
Global Rationale: Muscarinic antagonists are prescribed to reduce the muscular tremor and rigidity associated with Parkinson disease. Diarrhea, increased urine output, and rhinorrhea are not affects of muscarinic antagonists.
