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

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.
Correct Answer is D
Explanation
Choice A rationale:
Absorption is not primarily affected by the functioning of hepatic enzymes.
Choice B rationale:
Distribution is not the main concern when dealing with abnormal functioning of hepatic enzymes.
Choice C rationale:
Excretion is mainly a function of the kidneys, not the liver.
Choice D rationale:
Metabolism is the aspect of pharmacokinetics most affected by the functioning of hepatic enzymes. The liver plays a crucial role in the metabolism of drugs.
