A client is suspected of having myasthenia gravis. A small dose of tubocurarine is administered, and the client develops increased muscle weakness. What would the nurse expect to immediately administer?

Question

1. A sympathetic stimulant
2. A cholinesterase inhibitor
3. A calcium channel blocker
4. A dopamine agonist

Answer 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.
