Question

1. order: methylprednisolone acetate (depo medrol) 80 mg im every other week. the strength on the label is 40 mg/ml. draw an arrow on the most appropriate syringe indicating the number of milliliters you will administer.

Explanation:

Step1: Recall the formula for dosage calculation

The formula to calculate the volume (in milliliters) of a medication to administer is \( \text{Volume} = \frac{\text{Desired Dose}}{\text{Strength of Medication}} \). Here, the desired dose is 80 mg and the strength is 40 mg/mL.

Step2: Substitute the values into the formula

Substitute the given values into the formula: \( \text{Volume} = \frac{80\ \text{mg}}{40\ \text{mg/mL}} \).

Step3: Perform the division

Simplify the expression: \( \frac{80}{40} = 2\ \text{mL} \). So, we need to administer 2 milliliters of the medication.

Answer:

2 milliliters (and the arrow should be drawn at the 2 mL mark on the appropriate syringe, likely the middle syringe in the image as it has markings up to 5 mL with clear indication for 2 mL).
