A home care nurse administers oral morphine to the patient with cancer pain.
When will the nurse expect the medication to reach peak activity?
45 minutes.
10 minutes.
30 minutes.
60 minutes.
The Correct Answer is A
Choice A rationale
Oral morphine typically reaches peak activity at around 45 minutes after administration. This allows time for the medication to be absorbed through the gastrointestinal tract and enter the bloodstream to provide pain relief.
Choice B rationale
10 minutes is too short for oral morphine to reach peak activity. This timeframe is more consistent with intravenous administration, which allows for rapid onset of action.
Choice C rationale
30 minutes is a bit too short for oral morphine to reach peak effect, although some patients may start to feel relief. However, peak plasma concentrations generally occur closer to 45-60 minutes.
Choice D rationale
While morphine can continue to have effects up to 60 minutes and beyond, the peak activity is typically observed around the 45-minute mark. Waiting for 60 minutes may underestimate the peak timeframe.

Correct Answer is ["D","E"]
Explanation
Choice A rationale
Asking the patient if they take any medication is redundant since this information has already been collected.
Choice B rationale
Inquiring if the patient takes "this medication" is vague and does not provide specific information about the types of medication they are taking.
Choice C rationale
Asking about medication safety practices does not directly relate to the types of medications the patient is taking.
Choice D rationale
It is important to ask about herbs, vitamins, or supplements as these can interact with prescribed medications and affect the patient's health.
Choice E rationale
Over-the-counter (OTC) medications can also have significant interactions with prescription drugs and impact the patient's overall health and treatment plan.
Correct Answer is B
Explanation
Choice A rationale
Administering amoxicillin when a patient has a known allergy to penicillin can result in a serious allergic reaction. It is important to avoid using any beta-lactam antibiotic in patients with a history of penicillin allergy.
Choice B rationale
Contacting the provider to discuss using a different antibiotic is the safest course of action. The provider can prescribe an alternative antibiotic that does not belong to the beta-lactam class, reducing the risk of an allergic reaction.
Choice C rationale
Asking the provider to order an antihistamine does not address the underlying risk of administering a beta-lactam antibiotic to a patient with a penicillin allergy. Antihistamines are used to manage allergic reactions, not to prevent them.
Choice D rationale
Requesting an order for a beta-lactamase resistant drug does not eliminate the risk of an allergic reaction, as these drugs still belong to the beta-lactam class and can trigger the same allergic responses in sensitive individuals.
