A nurse is preparing to administer levothyroxine 150 mcg PO. Available is levothyroxine 75 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"]
To give the correct dose of levothyroxine, the nurse needs to calculate how many tablets of 75 mcg are equivalent to 150 mcg. The nurse can use a proportion to solve this problem. Let x be the number of tablets to administer. Then, the proportion is:
75 mcg / 1 tablet = 150 mcg / x tablets
Cross-multiplying, we get:
75x = 150
Dividing both sides by 75, we get:
x = 2
Therefore, the nurse should administer 2 tablets of levothyroxine 75 mcg to give a total of 150 mcg.

Correct Answer is A
Explanation
A. Shake the suspension well before each administration.
The medication label specifically states, "IMPORTANT: SHAKE WELL BEFORE EACH USE," and "THIS PRODUCT MUST BE SHAKEN WELL ESPECIALLY PRIOR TO INITIAL USE." This indicates the necessity of shaking the suspension before administration to ensure proper mixing of the medication.
B. Dilute the suspension with 38 mL water prior to initial use.
There is no indication on the label to dilute the suspension with water. The label emphasizes shaking well before use, but dilution is not mentioned.
C. Store the suspension in the refrigerator.
The storage instructions on the label state, "Store at 20° to 25°C (68° to 77° F) see USP controlled room temperature." Refrigeration is not mentioned, and it is not recommended to deviate from the specified storage conditions.
D. Discard the suspension 14 days after opening the bottle.
The label does not provide specific information about the shelf life after opening. Therefore, it is essential to follow the specific instructions on the label or refer to the package insert for complete prescribing information regarding the expiration or discard date after opening. The information on the label does not specify a 14-day limit.
Correct Answer is ["125"]
Explanation
To calculate the infusion rate for lactated Ringer's solution, the nurse should divide the total volume of fluid by the total time of infusion.
In this case, the nurse should divide 500 mL by 4 hr, which equals 125 mL/hr.
Therefore, the nurse should set the IV pump to deliver 125 mL/hr of lactated Ringer's solution.
