Which range of the normal adult dose, with the amount of medication increasing over time, is used when initiating drug therapy in elderly adults?.
One-eighth to one-fourth.
One-fourth to one-third.
One-half to three-fourths.
One-third to one-half.
The Correct Answer is D
Choice A rationale:
One-eighth to one-fourth of the normal adult dose is not typically used when initiating drug therapy in elderly adults. This range might be too low to be effective.
Choice B rationale:
One-fourth to one-third of the normal adult dose is also not typically used when initiating drug therapy in elderly adults. This range might still be too low to be effective.
Choice C rationale:
One-half to three-fourths of the normal adult dose is not typically used when initiating drug therapy in elderly adults. This range might be too high and increase the risk of adverse effects.
Choice D rationale:
One-third to one-half of the normal adult dose is used when initiating drug therapy in elderly adults. This range is appropriate to balance efficacy and safety.

Correct Answer is C
Explanation
Choice A rationale:
Giving the medication as ordered despite the patient’s stated allergy could lead to a severe allergic reaction.
Choice B rationale:
While checking the drug insert for information on reactions to the drug is important, the immediate action should be to withhold the medication.
Choice C rationale:
Withholding the medication and notifying the prescriber of the situation is the safest course of action when a patient states they are allergic to the medication.
Choice D rationale:
Giving the medication and monitoring the patient for adverse effects is not safe if the patient has stated they are allergic to the medication.
