Final answer:
The level of risk involved is medium. Proper aseptic technique and accurate dosage calculation are important.
Step-by-step explanation:
The level of risk involved in reconstituting a vial of cefazolin and placing it in a piggyback IV bag can be considered as a medium risk activity.
When reconstituting a vial of cefazolin, it is important to follow proper aseptic technique to minimize the risk of contamination. This includes using sterile equipment, maintaining a clean work environment, and properly mixing the medication.
Additionally, it is essential to accurately calculate the appropriate dosage and concentration of the medication to be added to the IV bag, as errors in dosage or concentration can have adverse effects on the patient.
