The practical nurse (PN) is preparing cefazolin 400 mg IM for a client with a gram-positive infection. The available vial is labeled, "Cefazolin 1 gram," and the instructions for reconstitution state, for IM use, add 2 mL sterile water for injection. The total volume after reconstitution is 2.5 mL.
After reconstitution, how many mL should be administered to the client?
(Enter numeric value only. If rounding is required, round to the whole number, nearest tenths/hundredth).
The Correct Answer is ["1"]
The concentration of cefazolin after reconstitution can be calculated as follows: Concentration = Total amount of drug / Total volume after reconstitution
Since the available vial contains 1 gram (1000 mg) of cefazolin and the total volume after reconstitution is 2.5 mL, we can calculate the concentration:
Concentration = 1000 mg / 2.5 mL = 400 mg/mL
Therefore, after reconstitution, the concentration of cefazolin is 400 mg/mL.
To administer a dose of 400 mg, we divide the desired dose by the concentration: Volume to administer = Desired dose / Concentration
Volume to administer = 400 mg / 400 mg/mL = 1 mL

Correct Answer is C
Explanation
A. Reporting drainage around the GT site is important for monitoring for infection, but it is not the most critical safety measure during the bath.
B. Using pillows to position the client can provide comfort and support, but it does not prevent a serious complication.
C. Keeping the head of the bed raised during continuous tube feeding is essential to reduce the risk of aspiration, which is a priority safety concern.
D. Raising the bed can reduce back strain for the UAP, but client safety takes precedence over staff ergonomics in this context.
Correct Answer is D
Explanation
Choice A reason:
Instructing the UAP in the correct removal of contaminated gloves focuses only on one aspect of the PPE removal process. While it is important to remove gloves correctly to prevent contamination, this choice does not address the comprehensive handling of all isolation attire. Proper PPE removal involves multiple steps, including the removal of gowns, masks, and gloves in a specific order to minimize the risk of contamination.
Choice B reason:
Reminding the UAP to remove the gown before removing gloves addresses part of the PPE removal process but not the entire procedure. The correct sequence for removing PPE is crucial to prevent self-contamination. However, this choice does not ensure that all steps are followed correctly. The PN needs to confirm that the UAP understands and correctly performs the entire process, not just one step.
Choice C reason:
Advising the UAP to remove the mask after exiting the room is incorrect because masks should be removed before leaving the isolation room to prevent contamination of the environment outside the isolation area. Droplet precautions require that masks be removed inside the room to contain any infectious agents within the isolation area. This choice could lead to the spread of infection if not followed correctly.
Choice D reason:
Confirming that the UAP has correctly handled the isolation attire ensures that all steps in the PPE removal process are followed correctly. This comprehensive approach helps maintain infection control standards and prevents the spread of infectious agents. By verifying that the UAP has correctly removed and disposed of all PPE, the PN ensures that the UAP adheres to proper protocols, thereby protecting both the healthcare workers and other clients.
