Answer to Question 1

ANS: A
A common cause of strychnine poisoning is accidental ingestion from strychnine-based rodenticides. The first manifestation of poisoning is stiffness in the muscles of the face and neck, followed by a generalized increase in reflex excitability.
The assessment findings are inconsistent with cocaine or methamphetamine overdose.
The assessment findings are not consistent with modafinil overdose or ingestion.

Answer to Question 2

ANS: C, D, E
Caffeine, which the patient is ingesting from the coffee beans daily, causes relaxation of bronchial smooth muscle, which promotes bronchodilation, nervousness, and diuresis secondary to vasodilation of the blood vessels in the peripheral vascular system.
Caffeine causes vasoconstriction of the blood vessels in the central nervous system.
Caffeine does not elevate serum sodium levels.
