Calculate the amount to administer:____________ (Round decimal appropriately)
Ordered: Imitrex 8 mg subcut prn headache
On hand: Imitrex injection 6 mg/0.5 mL
Full Explanation
Desired dose = 8 mg.
Concentration of the available medication = 6 mg in 0.5 mL.
Concentration = 6 mg / 0.5 mL
= 12 mg/mL.
- Calculate the volume in milliliters (mL) to administer.
Volume (mL) = Desired dose (mg) / Concentration (mg/mL)
= 8 mg / 12 mg/mL
= 0.6666... mL.
- Rounding to the nearest hundredth
= 0.67 mL.
How many grams of dextrose are in 1,000 mL of D10W?
A. 1,000 grams
B. 10 grams
C. 100 grams
Calculation: D10W stands for Dextrose 10% in Water.2 This means the solution contains 10 grams of dextrose for every 100 mL of solution. Calculate the total grams of dextrose in 1,000 mL. Using a ratio: 10 g/100 mL =x/1000 mL. To solve for x: x= (10 g×1000 mL)/ 100mL =10 g×10 =100 grams
D. 1 gram

- Calculate the total grams of dextrose in 1,000 mL.
Using a ratio:
10 g/100 mL =x/1000 mL.
To solve for x:
x= (10 g×1000 mL)/ 100mL
=10 g×10
=100 grams
Find the flow rate for manual regulation:__________.
Ordered: 220 mL D5LR to infuse over 4 h using tubing calibrated to 60 gtt/mL
Full Explanation
Calculation:
Total volume = 220 mL.
Drop factor = 60 gtt/mL.
- Convert the total time from hours to minutes.
Total time = 4 hours × 60 minutes/hour
= 240 minutes.
- Calculate the flow rate.
Flow rate (gtt/min) = (Total volume (mL) × Drop factor (gtt/mL)) / Time (min)
= (220 mL × 60 gtt/mL) / 240 minutes
= 13200 gtt / 240 minutes
= 55 gtt/min.
