The patient prefers to take an herbal supplement rather than the prescription medication ordered by the physician. Which is the most appropriate response of the nurse?
"It is very convenient to take herbal supplements because they can be obtained without a prescription."
"Herbal supplements are significantly less expensive than prescription medications."
"Herbal supplements are not held to the same high-quality standards as prescription medications."
"Herbal supplements are made from plant materials so they are organic and nontoxic."
The Correct Answer is C
Choice A reason: Convenience doesn’t ensure efficacy; supplements lack rigorous testing, potentially delivering inconsistent doses or contaminants, unlike prescription drugs’ controlled standards.
Choice B reason: Cost isn’t a clinical justification; lower price may reflect unregulated production, risking potency or safety compared to prescriptions validated by scientific trials.
Choice C reason: Supplements aren’t FDA-regulated like prescriptions; lacking standardized purity and efficacy tests, they may contain variable active ingredients, posing therapeutic risks.
Choice D reason: Plant-based doesn’t guarantee safety; many herbs are toxic or interact harmfully with drugs, unlike prescriptions with established pharmacokinetics and safety profiles.

Correct Answer is D
Explanation
Choice A reason: Withholding delays treatment; nausea may persist, risking vomiting of the dose if given later, reducing bioavailability and therapeutic effect over time.
Choice B reason: Sips of water won’t prevent vomiting; with ongoing nausea, the oral dose is likely expelled, decreasing absorption and failing to deliver the medication effectively.
Choice C reason: Crackers may worsen nausea or fail to retain the dose; vomiting risks remain high, compromising oral administration’s reliability in this acute condition.
Choice D reason: Rectal or parenteral routes bypass the stomach, ensuring delivery despite vomiting; this maintains therapeutic levels, critical for efficacy in a nauseated patient.
Correct Answer is A
Explanation
Choice A reason: Respiratory depression from high morphine doses signals toxicity; opioids suppress the brainstem’s respiratory center, exceeding safe therapeutic levels at this extent.
Choice B reason: Allergic reactions involve immunity (e.g., rash, anaphylaxis); slowed breathing isn’t allergic, but a dose-dependent opioid effect on respiration.
Choice C reason: Idiosyncratic means unexpected (e.g., paradoxical excitement); respiratory depression is a predictable morphine overdose sign, not an unusual reaction.
Choice D reason: Therapeutic effects relieve pain; 8 breaths/minute is dangerously low, beyond intended analgesia, indicating a harmful, not beneficial, outcome.
