Question 2 :
A nurse is preparing to administer cefazolin 500 mg IM every 8 hr. Available is cefazolin 1 g vial. The package insert instructs adding sterile water 2.5 mL to yield cefazolin 330 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: ["1.5ml"]
To calculate the volume (mL) that the nurse should administer per dose, you can use the following formula:
Volume (mL) = Dose (mg)/Concentration (mg/mL)
In this case:
Volume = 500 mg/ 330 mg/mL
Volume≈1.5mL
Therefore, the nurse should administer approximately 1.5 mL per dose of cefazolin 500 mg IM.
