A nurse is preparing to administer hydromorphone 2.5 mg PO every 6 hours for a client with severe pain. The amount available comes in a liquid form (5 mg/5 mL). How many mL should the nurse administer per day (24 hours)? (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 ["10"]
Step by step calculation:
Determine the dosage required per administration: 2.5 mg
Determine the concentration available: 5 mg/5 mL= 1 mg/mL
Use the formula to calculate the volume per dose:
Volume per dose (mL)=Required dose (mg)/Concentration (mg/mL)
Volume per dose (mL)=2.5 mg/1 mg/mL=2.5 mL
Calculate the number of doses per day: Every 6 hours means 4 doses per day.
Calculate the total volume per day:
Total volume per day (mL)=Volume per dose (mL) × Number of doses per day
Total volume per day (mL)=2.5 mL × 4=10 mL
