A nurse is preparing to administer levothyroxine 0.05 mg PO to a client. Available is levothyroxine 25 mcg tablets. How many tablets should the nurse plan to 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 "]
Given:
- Desired dose of levothyroxine: 0.05 mg
- Available strength of levothyroxine tablets: 25 mcg
First, convert the desired dose from milligrams to micrograms:
0.05 mg = 50 mcg
Number of tablets = Desired dose / Strength per tablet
Number of tablets = 50 mcg / 25 mcg/tablet Number of tablets = 2 tablets
So, the nurse should plan to administer 2 tablets of levothyroxine.

Correct Answer is ["0.4 "]
Explanation
Given:
- Desired dose of chlorpromazine: 0.55 mg/kg every 6 hours
- Child's weight: 44 lb
- Available strength of chlorpromazine injection: 25 mg/mL
First, convert the child's weight from pounds to kilograms:
44 lb ÷ 2.20462 = 20 kg
Now, let's calculate the desired dose of chlorpromazine:
Desired dose = Dosage per kg × Weight Desired dose = 0.55 mg/kg × 20 kg Desired dose = 11 mg
Now, let's find out how many milliliters of chlorpromazine correspond to this dose: Volume (mL) = Desired dose / Concentration
Volume (mL) = 11 mg / 25 mg/mL Volume (mL) ≈ 0.44 mL
So, the nurse should administer approximately 0.4 mL of chlorpromazine per dose.
