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 A
Explanation
Step 1 is 2 hours × 60 minutes = 120 minutes.
Step 2 is (250 mL ÷ 120 minutes) × 15 gtts/mL.
Step 3 is 2.08333 mL/min × 15 gtts/mL = 31.24995 gtts/min.
Step 4 is 31.24995 rounded to the nearest whole number is 31.
The final calculated answer is 31 gtts/min.
Correct Answer is B
Explanation
Choice A reason: Juice may alter absorption; liquid can dilute or degrade some drugs, and taste may deter intake, reducing effectiveness compared to soft food.
Choice B reason: Applesauce masks taste and aids swallowing; it ensures crushed medication is consumed fully, maintaining dose integrity without altering pharmacokinetics significantly.
Choice C reason: Water may not mask bitterness; some drugs dissolve poorly or lose potency, and patients may not finish it, risking incomplete dosing.
Choice D reason: Meat or vegetables may bind drugs; uneven distribution or strong flavors could reduce intake, compromising the full therapeutic dose delivery.
