An adolescent diagnosed with hypothyroidism is prescribed Levothyroxine 100 mcg po daily. The medication is supplied in 0.1mg tablets. How much should the nurse administer?(Use a leading zero if it applies, do not use a trailing zero, Round to a whole number)
Answer and Explanation

The Correct Answer is ["1"]

To calculate the correct dosage:

  1. Convert the prescribed dose (100 mcg) to milligrams:
    • 1 mg = 1000 mcg, so 100 mcg = 0.1 mg.
  2. The available tablets are 0.1 mg each.
  3. The prescribed dose is 0.1 mg, and the tablet strength is also 0.1 mg. Therefore, the nurse needs to administer 1 tablet.
