(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["2"]

The correct answer is 2 tablets. Step 1 is to determine the total amount of levothyroxine needed, which is 100 mcg.

Step 2 is to divide the total amount needed by the amount available per tablet.

So, 100 mcg ÷ 50 mcg/tablet equals 2 tablets.

So, the correct answer is 2 tablets

Correct Answer is C

Explanation

Choice A rationale:

Decreased splanchnic blood flow can affect drug absorption and metabolism, but it does not directly increase the risk of gastric irritation from NSAIDs.

Choice B rationale:

Prolonged secretion of gastric acid can contribute to conditions like gastroesophageal reflux disease (GERD), but it is not the primary factor increasing the risk of gastric irritation from NSAIDs in older adults.

Choice C rationale:

Delayed gastric emptying is the correct answer. It allows drugs to stay in contact with the stomach lining for a longer time, which can increase the risk of gastric irritation from NSAIDs.

Choice D rationale:

Loss of cells from the gastric plexus can affect gastric function, but it is not directly linked to an increased risk of gastric irritation from NSAIDs.

A. Has a wider therapeutic range than drug B. B. Has a higher rate of protein binding than drug B. C. Has a longer half-life than drug B. D. Is less toxic than drug B.

Correct Answer is C

Explanation

Choice A rationale:
The frequency of drug administration doesn’t necessarily determine the therapeutic range.
Choice B rationale:
Protein binding is not directly related to the frequency of drug administration.
Choice C rationale:
Drug A has a longer half-life than drug B. This is because drugs with longer half-lives need to be administered less frequently.
Choice D rationale:
The toxicity of a drug is not determined by the frequency of its administration.
