Answer to Question 1

Correct Answer: 3
Rationale: Opioid agonists stimulate mu and kappa receptors, resulting in a variety of effects, including analgesia. There are at least six types of receptors. The mu and kappa receptors are of greatest concern from a pharmacologic standpoint. Drugs that block opioid receptors are called opioid antagonists, and do not inhibit the pain impulse.

Answer to Question 2

Correct Answer: 3
Rationale: Administering the opioid antagonist naloxone (Narcan) is indicated in the given situation. Lowering the dose is not aggressive enough, and intubation is too aggressive. Activated charcoal is not indicated for an overdose that has occurred via the IV route.
