Indication for administration of the Mark 1 NAAK is exposure to what?

Indication for administration of the Mark 1 NAAK is exposure to what?

• A. Allergens
• B. Nerve agents
• C. Bacteria
• D. Hypoglycemic agents

Answer: (B)

The main idea here is recognizing what this specific antidote kit is designed to treat. The Mark 1 NAAK is a chemical-defense autoinjector used when there is exposure to organophosphate nerve agents. Nerve agents inhibit acetylcholinesterase, causing a surge of acetylcholine that leads to excessive muscarinic and nicotinic effects such as drooling, sweating, bronchospasm, difficulty breathing, bradycardia, and muscle fasciculations. The kit delivers atropine to block the muscarinic effects and pralidoxime to reactivate acetylcholinesterase, addressing the underlying toxin. Because of this mechanism, the indication is nerve-agent exposure, not exposure to allergens, bacteria, or hypoglycemic agents.
