Calculate the amount to administer:____________ (Round decimal appropriately)
Ordered: Imitrex 8 mg subcut prn headache
On hand: Imitrex injection 6 mg/0.5 mL
The Correct Answer is ["0.67"]
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.

Correct Answer is A
Explanation
A. 60 gtt/mL: Microdrip tubing universally delivers 60 drops per milliliter (gtt/mL). It is used when precise, small-volume infusions are required, such as for pediatrics or medication titration.
B. 20 gtt/mL: This is a common drop factor for macrodrip tubing, not microdrip. It delivers larger drops and is used for general fluid administration, not precise dosing.
C. 10 gtt/mL: This drop factor also applies to macrodrip tubing, especially for rapid fluid replacement. It is not suitable for microdrip administration.
D. 15 gtt/mL: Like 10 and 20, this is another macrodrip factor. It is used for routine fluid infusions, but does not provide the fine control offered by microdrip tubing.
