Question

Ordered: cefadyl 400 mg IM q6h. Available: cefadyl 1 g.

Directions: Add 2mL Bacteriostatic Water for injection. Each 1.2 mL
contains 500 mg of cephapirin. How many mL will you inject?

Answer 1

To inject 400 mg of cefadyl, you would inject 0.96 mL of the medication.

Step-by-step explanation:

To calculate the mL of cefadyl to inject, we need to find out how many mg of cephapirin are in 400 mg of cefadyl. From the instructions, we know that 1.2 mL contains 500 mg of cephapirin. So, we can set up a proportion:

1.2 mL / 500 mg = X mL / 400 mg

Cross-multiplying, we get:

500 mg * X mL = 1.2 mL * 400 mg

Dividing both sides by 500 mg:

X mL = (1.2 mL * 400 mg) / 500 mg

Simplifying the equation:

X mL = 0.96 mL

Therefore, you would inject 0.96 mL of cefadyl.
