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 B
Explanation
Monitoring the client's vital signs, including temperature, heart rate, respiratory rate, and blood pressure, is crucial to assess for any signs of infection or complications following surgery.
A. While fluid volume intake and output are important to monitor for overall hydration status, it is not the most immediate concern after reinforcing the dressing.
C. Similarly, assessing the volume of peripheral pulses is important to evaluate peripheral perfusion, but it may not be the highest priority at this time.
D. Incisional pain scale rating is important to assess the client's comfort and pain level, but it should be done after ensuring the security of the surgical dressing.
Correct Answer is A
Explanation
Inspecting the client's skin near the end of the bathing procedure allows the PN to directly assess the UAP's performance and evaluate the effectiveness of the bed bath. By observing the client's skin, the PN can determine if the UAP has properly cleaned and cared for the client's skin, identified any areas that may have been missed, and ensured that proper hygiene practices have been followed.
B. While verifying with the client that the bath was complete and thorough is important for client satisfaction, it may not provide a comprehensive evaluation of the UAP's performance. Clients may not be aware of all the necessary steps involved in a complete bed bath, so their perception may not accurately reflect the quality of the UAP's work.
C. Requesting the UAP to report and chart when the bath is complete is a useful documentation practice, but it does not provide a direct evaluation of the UAP's performance during the bed bath.
D. Asking another UAP to help the orientee may be helpful for providing guidance and support during the orientation process, but it does not provide a specific evaluation of the UAP's performance in completing the bed bath.
