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 D
Explanation
When the PN witnesses a situation where a resident is shouting profanities and a staff member (UAP) responds inappropriately, the immediate priority is to ensure the safety and well-being of the resident. It is essential to address the situation promptly and prevent further escalation.
Entering the room and instructing the UAP to leave immediately serves several purposes:
1. Protecting the resident: Removing the UAP from the room ensures that the resident is not subjected to further conflict or distress.
2. Maintaining a calm and therapeutic environment: By addressing the disruptive behavior and removing the staff member involved, the PN can help restore a peaceful environment for the resident and other individuals in the facility.
3. Ensuring professional conduct: Shouting and engaging in unprofessional behavior is not acceptable in a healthcare setting. By immediately intervening and directing the UAP to leave the room, the PN reinforces the importance of maintaining a respectful and professional approach to caregiving.
After addressing the immediate concern, the PN should follow up by reporting the incident and providing a detailed account to the nurse manager or supervisor. This allows for appropriate action to be taken, such as further investigation or disciplinary measures if necessary.
The other options mentioned are not the first actions to be taken in this situation:
A. Reporting the incident and the UAP for further action by the nurse manager: While reporting the incident is important, it is not the immediate action required to address the situation in
real-time.
B. Telling both of them to lower their voices in consideration of other residents: While promoting a calm environment is important, addressing the issue of shouting and unprofessional behavior takes precedence over requesting a volume reduction.
C. Telling the resident and the UAP that shouting is not permitted: While it is essential to communicate the expectations of behavior, the immediate focus should be on removing the staff member from the situation and ensuring the resident's well-being.
Correct Answer is A
Explanation
Collecting fingerstick glucose levels is the most important intervention for the PN to implement for a client who is receiving TPN. TPN is a method of feeding that bypasses the gastrointestinal tract and provides all the nutritional needs of the body through a vein. TPN contains a high concentration of glucose, which can cause hyperglycemia or fluctuations in blood sugar levels. Therefore, it is essential to monitor the client's glucose levels frequently and adjust the infusion rate or insulin administration accordingly.
