Answer to Question 1

Correct Answer: 2
Rationale 1: A sympathetic blocking agent, not a sympathetic stimulant, would be indicated.
Rationale 2: A cholinesterase inhibitor will reverse effects of tubocurarine.
Rationale 3: A calcium channel blocker would not affect muscle strength.
Rationale 4: A dopamine antagonist, not a dopamine agonist, would be indicated.
Global Rationale: A cholinesterase inhibitor will reverse effects of tubocurarine. A sympathetic blocking agent, not a sympathetic stimulant, would be indicated. A calcium channel blocker would not affect muscle strength. A dopamine antagonist, not a dopamine agonist, would be indicated.

Answer to Question 2

Correct Answer: 2
Rationale 1: Acetaminophen should not interact with succinylcholine.
Rationale 2: Aminoglycosides can attach to the same binding site, causing an intensified reaction.
Rationale 3: Ibuprofen should not interact with succinylcholine.
Rationale 4: Opioids should not interact with succinylcholine.
Global Rationale: Aminoglycosides can attach to the same binding site, causing an intensified reaction. Acetaminophen, aminoglycosides, and opioids should not interact with succinylcholine.
