For the following question, list the answer using numbers. Example: 1, 10, 100.
Ordered Vantin 175 mg po q 12 hours.
See label for dose on hand.
Amount to administer ___________mL
The Correct Answer is ["17.5"]
Ordered dose: 175 mg.
- Determine the concentration of the medication from the label.
The label states the concentration is 50 mg per 5 mL.
Concentration:
50 mg / 5 mL

Volume (mL) = Desired Dose / Concentration
= 175 mg / 10 mg/mL
= 17.5 mL.

Correct Answer is ["1008"]
Explanation
Calculation:
Given values:
Flow rate = 21 gtt/min
Infusion time = 8 hours
Drop factor = 10 gtt/mL
- Convert the infusion time from hours to minutes.
Infusion time in minutes = 8 hours × 60 minutes/hour
= 480 minutes.
- Calculate the total volume in milliliters (mL).
Total Volume (mL) = (Flow rate (gtt/min) × Time (min)) / Drop factor (gtt/mL)
= (21 gtt/min × 480 min) / 10 gtt/mL
= 10080 / 10
= 1008 mL.
Correct Answer is ["3"]
Explanation
Desired dose = 144 mg.
Available strength = 48 mg/tablet.
- Calculate the number of tablets to administer.
Number of tablets = Desired dose (mg) / Available strength (mg/tablet)
= 144 mg / 48 mg/tablet
= 3 tablets.
