To determine how many mL of the tramadol liquid the medical assistant (MA) will administer, we need to calculate the appropriate dosage based on the concentration of the available vials.
Given:
- Physician orders 15 mg of tramadol (liquid).
- On hand are 30 mg/2 mL vials.
To find the required mL of the liquid to administer, we can set up a proportion using the concentration of the vials:
30 mg / 2 mL = 15 mg / x mL
Cross-multiplying, we get:
30 mg * x mL = 15 mg * 2 mL
Simplifying:
30x = 30
Dividing both sides by 30:
x = 1
Therefore, the MA will administer 1 mL of the tramadol liquid to provide the ordered dosage of 15 mg.
