A nurse is preparing to administer levothyroxine 100 mcg PO to a client who has hypothyroidism.
Available is levothyroxine 50 mcg tablets.
How many tablets should the nurse administer?
(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
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

Explanation
Choice A rationale:
The blood flow of the mucous lining of the stomach and intestines can affect how quickly a drug is absorbed.
Choice B rationale:
Drug distribution refers to how a drug spreads throughout the body, not its absorption in the gastrointestinal tract.
Choice C rationale:
Enzyme activity can affect how a drug is metabolized and absorbed.
Choice D rationale:
Gastric pH can affect drug absorption as some drugs are better absorbed in an acidic environment, while others are better absorbed in an alkaline environment.
Choice E rationale:
Gastric emptying time can affect drug absorption. Drugs may stay in contact with the absorptive tissue longer if the gastric emptying time is slower, allowing for increased absorption.
