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
Volume (mL) = Desired dose / Concentration
Volume (mL) = 4 mg / 10 mg/mL
Volume (mL) = 0.4 mL
Correct Answer is ["1 "]
Explanation
Given:
- Desired dose of metronidazole: 7.5 mg/kg
- Client's weight: 146.7 lb
- Available strength of metronidazole tablets: 500 mg
First, convert the client's weight from pounds to kilograms:
146.7 lb ÷ 2.20462 = 66.57 kg (rounded to the nearest hundredth)
Now, calculate the desired dose of metronidazole:
Desired dose = Dosage per kg × Weight Desired dose = 7.5 mg/kg × 66.57 kg Desired dose ≈ 498.775 mg
Next, find out how many tablets are needed to achieve this dose: Number of tablets = Desired dose / Strength per tablet
Number of tablets = 498.775 mg / 500 mg Number of tablets ≈ 0.997
Since we cannot administer a fraction of a tablet, the nurse should administer 1 tablet of metronidazole.
