Final answer:
The nurse would administer 4 mL of Apresoline with each dose, calculated by setting up a proportion based on the ordered dose of 10 mg and the available concentration of 5 mg per 2 mL.
Step-by-step explanation:
The question requires the calculation of the volume of Apresoline to administer, given the medication's concentration and the prescribed dose. The order is for Apresoline 10 mg IV every 4 hours, and the concentration available is 5 mg/2 mL. To calculate the required volume for the dose, we use a simple proportion:
Given:
- Ordered dose: 10 mg
- Concentration available: 5 mg per 2 mL
Setting up the proportion we have:
5 mg : 2 mL = 10 mg : x mL
To solve for x (the volume to administer), we cross-multiply and divide:
(5 mg) × (x mL) = (10 mg) × (2 mL)
5x = 20
x = 20 / 5
x = 4 mL
Therefore, the nurse would administer 4 mL of Apresoline with each dose.
