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 C
Explanation
the correct rate to administer the maintenance dose is 50 mL/hr.
Step 1: Determine the concentration of magnesium sulfate in the solution.
- There are 40 grams of magnesium sulfate in 1 liter of solution.
- 1 liter = 1000 mL.
Step 2: Calculate the concentration in grams per mL.
- 40 grams ÷ 1000 mL = 0.04 grams per mL.
- Result: 0.04 grams per mL.
Step 3: Determine the required dose per hour.
- The physician ordered 2 grams per hour.
Step 4: Calculate the volume of solution needed to provide 2 grams of magnesium sulfate.
- Required dose (2 grams) ÷ concentration (0.04 grams per mL) = volume in mL.
- 2 grams ÷ 0.04 grams per mL = 50 mL.
- Result: 50 mL.
- The calculated rate is 50 mL/hr.
the correct rate to administer the maintenance dose is 50 mL/hr.
