Answer:
4 mL per dose
Step-by-step explanation:
The ordered dose of the medication as written by the provider is 12 mg IV once.
Concentration or dosage strength of the medication is 6 mg / 2mL or 6 mg per 2 mL. We will use the reciprocal of this proportion in the next part.
In order to calculate the dose to be administered to the patient, the pharmacy tech must multiply the ordered dose by the dosage strength. This can be represented by the following formula:
ordered dose X dosage strength = dose to be administered
12 mg X 2 mL / 6 mg
24 mg mL / 6 mg
4 mg mL / mg
Milligrams (mg) in both the numerator and denominator cancel each other out. This leaves only milliliters (mL) as the units of measurements.
Therefore, the pharmacy technician should dispense 4 mL of adenosine.
