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.

Choice D rationale:
Anaphylaxis is a severe, life-threatening allergic reaction, but it is not the most common symptom.
Correct Answer is D
Explanation
Choice A rationale:
Protein binding does not inactivate the drug. Instead, it can affect the drug’s distribution and bioavailability.
Choice B rationale:
Protein binding does not directly increase the risk of an allergic reaction. Allergic reactions are typically immune responses to a drug, not a result of protein binding.
Choice C rationale:
An idiosyncratic reaction is an unusual or unexpected reaction to a drug, which is not related to protein binding.
Choice D rationale:
Protein binding can lead to the accumulation of the drug. Drugs often cannot cross membranes mainly due to the high molecular mass of the drug-protein complex, resulting in the accumulation of the active compounds.
