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 D
Explanation
Choice A reason: Administering insulin at proper timing correlates with mealtimes. However, this alone doesn't ensure safe practice.
Choice B reason: Confirming the injection site prevents lipodystrophy but does not address dose accuracy, which is vital for safety.
Choice C reason: Insulin is injected subcutaneously, not in the deltoid muscle. Using incorrect sites disrupts absorption.
Choice D reason: Double-checking insulin dose prevents administration errors, ensuring compliance with medication safety protocols.
Correct Answer is A
Explanation
Choice A reason: Alcohol and hepatitis C impair liver function; acetaminophen’s metabolite NAPQI accumulates, causing hepatotoxicity in an already compromised organ.
Choice B reason: COPD and smoking affect lungs, not liver; acetaminophen metabolism is minimally impacted, posing lower hepatic risk compared to liver disease states.
Choice C reason: Renal disease affects drug excretion, not liver metabolism; acetaminophen’s hepatic load is unchanged, making liver damage less likely here.
Choice D reason: Prostate issues involve urinary tract; liver metabolism of acetaminophen remains intact, with no heightened risk of hepatotoxicity from this condition.
