The patient's respirations dropped from 14 breaths/minute to 8 breaths/minute after receiving a large dose of morphine. Which term accurately describes the patient's reaction to the morphine?
Toxic
Allergic
Idiosyncratic
Therapeutic
The Correct Answer is A
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.

Correct Answer is C
Explanation
Choice A reason: While documentation and supervisor notification are crucial, immediate action involving the health care provider ensures timely response to potential adverse effects from the medication error.
Choice B reason: Relying solely on the absence of drug allergies is insufficient and may jeopardize patient safety. Errors require immediate communication and reporting for appropriate interventions.
Choice C reason: Timely provider notification prioritizes patient safety and enables corrective measures. Completing an incident report supports institutional transparency and learning to prevent future errors.
Choice D reason: Administering additional drugs risks compounding harm. The priority is addressing the initial error and ensuring patient safety without introducing further interventions.
Correct Answer is D
Explanation
Choice A reason: Moderate reactions don't cause breathing difficulty or hypotension. Severe symptoms indicate anaphylaxis, requiring emergency intervention.
Choice B reason: Symptoms align with anaphylaxis, not food poisoning. Assuming an unrelated cause delays life-saving treatment.
Choice C reason: Mild reactions lack systemic effects like hypotension and breathing difficulties. Antihistamines alone are insufficient for anaphylaxis.
Choice D reason: Anaphylaxis involves systemic reactions such as hypotension, airway constriction, and skin symptoms. Immediate interventions prevent progression and save lives.
