Distribution.

Absorption.

Excretion.

Metabolism.

Answer and Explanation

The Correct Answer is D

Choice A rationale:
While distribution can affect a person’s response to medication, it is not the aspect of genetic makeup most likely to alter this response.
Choice B rationale:
Absorption can affect how a drug is taken up by the body, but it is not the aspect of genetic makeup most likely to alter a person’s response to medication.
Choice C rationale:
Excretion, or how the body eliminates a drug, can affect drug response, but it is not the aspect of genetic makeup most likely to alter this response.
Choice D rationale:
Metabolism, or how the body processes a drug, is the aspect of genetic makeup most likely to alter a person’s response to medication. Genetic differences can lead to variations in drug-metabolizing enzymes, affecting how quickly or slowly drugs are metabolized.

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 ["83"]

Explanation

Step 2 is to substitute these values into the formula for calculating the manual IV flow rate: Flow Rate ® = (V ÷ T) × C

Step 3 is to perform the calculation: R = (250 mL ÷ 30 min) × 10 gtt/mL R = 83.33 gtt/min

Since we need to round off to the nearest whole number, the flow rate is 83 gtt/min.
