Correct Answer is D
Explanation
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 A
Explanation
Choice A rationale:
A decrease in blood pressure is a common side effect when a medication increases urine output, as the reduction in fluid volume can lead to lower blood pressure.
Choice B rationale:
While a decrease in blood pressure might be desired in certain conditions (like hypertension), in this context it is a side effect, not the primary desired effect.
Choice C rationale:
The therapeutic effect of the medication in this case is to increase urine output, not to decrease blood pressure.
