(Record the answer to the tenth, or one decimal place. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.5"]
- The formula is: (Desired dose / Available dose) x Quantity = Number of tablets - In this case: (10 mg / 20 mg) x 1 tablet = 0.5 tablet
- Round the answer to the tenth, or one decimal place, as instructed.
- The final answer is: 0.5 tablet

Correct Answer is ["0.3"]
Explanation
-
Convert the ordered dose from micrograms (mcg) to milligrams (mg):
- 300 mcg = 0.3 mg (since 1 mg = 1000 mcg)
-
Use the formula:
Dose to administer = (Desired Dose ÷ On-Hand Dose) × Quantity Available- Desired Dose (D) = 0.3 mg
- On-Hand Dose (H) = 1 mg
- Quantity Available (Q) = 1 mL
-
Calculate:
0.3 mg ÷ 1 mg × 1 mL = 0.3 mL
The nurse should administer 0.3 mL of the medication.
