Question

A patient has a respiratory infection, and the primary health-care provider prescribes ciprofloxacin (Cipro) 400 mg IM injection every 8 hours. The vial of ciprofloxacin states that there is 50 mg per mL. How many mL should be obtained to prepare the prescribed IM?

Answer 1

To prepare the prescribed IM injection of ciprofloxacin, you should obtain 8 mL of the medication.

Step-by-step explanation:

To calculate the volume of ciprofloxacin needed for the IM injection, we need to find the total amount of the medication required and then convert it to the appropriate volume. The prescription states that 400 mg of ciprofloxacin should be given every 8 hours. The vial concentration is 50 mg/mL, so we can use the equation: 400 mg x (1 mL / 50 mg) = 8 mL. Therefore, 8 mL of ciprofloxacin should be obtained to prepare the prescribed IM injection.
