A nurse is educating a client about a new prescription for celecoxib.
Which of the following information should the nurse include in the teaching about the medication's mechanism of action?
Inhibits histamine response.
Inhibits COX-2.
Inhibits COX-1.
Inhibits beta receptors.
The Correct Answer is B
Choice A rationale
Celecoxib does not inhibit the histamine response. Histamine is involved in allergic reactions, and celecoxib is a nonsteroidal anti-inflammatory drug (NSAID) that targets specific enzymes involved in inflammation.
Choice B rationale
Celecoxib specifically inhibits COX-2, an enzyme involved in the inflammation pathway. This selective inhibition helps reduce inflammation and pain without significantly affecting COX-1, which is protective for the stomach lining.
Choice C rationale
COX-1 is not the primary target of celecoxib. Inhibition of COX-1 can lead to gastrointestinal side effects, which celecoxib aims to minimize by selectively inhibiting COX-2 instead.
Choice D rationale
Celecoxib does not inhibit beta receptors. Beta receptors are involved in cardiovascular responses, and beta blockers are used for conditions like hypertension, not inflammation.

Correct Answer is ["A","B","C"]
Explanation
Choice A rationale
Determining the dosage is a critical responsibility of the nurse to ensure the patient receives the correct amount of medication, which is essential for therapeutic effectiveness and patient safety. This practice aligns with legal guidelines to avoid underdosing or overdosing, which could lead to adverse outcomes.
Choice B rationale
Teaching the client about the medication is part of the nurse's duty to promote patient understanding, compliance, and informed consent. Educating clients about their medications, including potential side effects and proper administration, helps in preventing medication errors and promoting safe, effective treatment.
Choice C rationale
Monitoring for adverse effects is crucial to ensure patient safety and the efficacy of the medication. Nurses must observe and report any negative reactions to the medication to adjust treatment promptly, which is part of their legal and ethical responsibilities.
Choice D rationale
Determining the client's insurance status is generally not considered part of a nurse's duties related to medication administration under legal practice guidelines. This task is more aligned with administrative or billing departments rather than clinical nursing responsibilities.
Correct Answer is A
Explanation
Choice A rationale
Opioid toxicity triad includes symptoms of pinpoint pupils, respiratory depression, and coma. These symptoms are indicative of a morphine sulfate overdose.
Choice B rationale
Orthostatic hypotension is a form of low blood pressure that happens when standing up from sitting or lying down. It is not related to opioid toxicity.
Choice C rationale
Hypertension is high blood pressure. It is not related to opioid toxicity.
Choice D rationale
Abstinence syndrome is a group of symptoms that occur upon the abrupt discontinuation or decrease in intake of medications or recreational drugs. It is not the appropriate complication for the client's presentation. .
