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 ["6"]
Explanation
Step 1 is to determine the amount of amoxicillin in each mL of the solution. This is done by dividing the total amount of amoxicillin in the solution (250 mg) by the total volume of the solution (5 mL). So, 250 mg ÷ 5 mL = 50 mg/mL. Step 2 is to determine how many mL of the solution is needed to administer 300 mg of amoxicillin.
This is done by dividing the desired dose (300 mg) by the amount of amoxicillin per mL (50 mg/mL). So, 300 mg ÷ 50 mg/mL = 6 mL.
So, the nurse should administer 6 mL of the amoxicillin oral solution. .
Correct Answer is D
Explanation
Choice A rationale:
While it’s true that hydration affects skin absorption, it’s not accurate to say that water-soluble drugs are not readily absorbed because the skin is not fully hydrated.
Choice B rationale:
Inflammation can actually increase the amount of drug absorbed due to increased blood flow and permeability.
Choice C rationale:
Topical administration with percutaneous absorption can be effective in infants, but it’s not always the case.
Choice D rationale:
Infants wearing plastic-coated diapers are indeed more susceptible to skin absorption. This is because the occlusive nature of the diaper can enhance absorption by increasing the hydration of the skin.
