A doctor orders 0.1 mg of Synthroid (levothyroxine), and 50 mcg tablets are available.
How many tablets per dose should the nurse administer to this patient?
1 tablet
3 tablets
4 tablets
2 tablets
The Correct Answer is D
The nurse should administer 2 tablets per dose to this patient.
This answer is correct because it is based on a simple unit conversion and ratio and proportion calculation. The nurse can convert 0.1 mg to 100 mcg by multiplying by 1000, since there are 1000 mcg in 1 mg. Then, the nurse can set up a proportion as follows:
50 mcg / 1 tablet = 100 mcg / x tablets
Cross-multiplying and solving for x gives:
x = 2 tablets
Therefore, the nurse should administer 2 tablets of Synthroid to deliver 0.1 mg or 100 mcg of the medication to the patient.

Correct Answer is B
Explanation
This is another dosage calculation problem. To solve it, we need to use the formula:
Caloric need ÷ Calories per mL 1000 = Formula per day
In this case, the caloric need is 2250 calories, and the calories per mL is 2000/1000 = 2. Plugging these values into the formula, we get:
2250 ÷ 2 × 1000 = 1125
Therefore, the client would need **1125 mL** of formula per day to meet the calorie requirements.
Correct Answer is C
Explanation
The nurse should administer 12.5 mL of amoxicillin oral suspension.
This answer is correct because it is based on a simple ratio and proportion calculation. The nurse can set up a proportion as follows:
200 mg / 5 mL = 500 mg / x mL
Cross-multiplying and solving for x gives:
x = 12.5 mL
Therefore, the nurse should administer 12.5 mL of amoxicillin oral suspension to deliver 500 mg of the medication to the patient.
