Answer to Question 1

D
The patient displays muscle weakness, which is an adverse effect of the tubocurarine and may precipitate respiratory degradation. The patient is experiencing a cholinergic crisis, and the nurse should administer an antagonist, such as a cholinesterase inhibitor.
A calcium channel blocker would not reverse the effects of tubocurarine.
A dopamine antagonist would not be indicated to reverse the effects of the tubocurarine.
A sympathetic stimulant would not be indicated to reverse the effects of the tubocurarine.

Answer to Question 2

B
Solvents are inhaled by three processes, referred to as bagging, huffing, and sniffing. Huffing involves pouring a solvent on a rag and inhaling the vapor.
Bagging involves pouring solvent in a plastic bag and inhaling the vapor.
Sniffing involves inhaling the solvent directly from it container.
Spraying the solvent directly into the nasal passage is not huffing.
