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
The client's question about whether the surgical opening will be visible suggests that they have concerns or misconceptions about the upcoming fecal diversion surgery. By reviewing the client's expectations of elimination after surgery, the PN can provide accurate information and address any anxieties or concerns the client may have.
The other options are not directly related to the client's question and are not the most appropriate actions to take in this situation:
A. Determining if this is the client's first indwelling catheter is unrelated to the client's question about the visibility of the surgical opening. It may be important to assess the client's history of urinary catheter use for other purposes, but it does not address the client's immediate concern.
B. Asking the client if they finished the bowel sterilization prescription is also unrelated to the visibility of the surgical opening. While bowel sterilization may be a part of the preoperative preparation for fecal diversion surgery, it does not address the client's questions and concerns.
D. Verifying that the client had nothing by mouth (NPO) for the past 24 hours is important for general preoperative care but does not address the client's specific question about the visibility of the surgical opening.
Correct Answer is C
Explanation
The activity that the PN should suggest to meet the physical and social needs of wheelchair-bound older residents who are mentally alert is an outdoor game of balloon
volleyball. It promotes physical activity, coordination, and social interaction among the residents. It allows them to engage with each other, participate in a fun and inclusive game, and enjoy the outdoor environment. Balloon volleyball can be adapted to accommodate individuals with varying abilities and provide an enjoyable and stimulating experience for wheelchair-bound residents who are mentally alert.
A. A picnic in the park: While a picnic in the park can be enjoyable, it may pose challenges for wheelchair-bound individuals in terms of accessibility and maneuverability. It might limit their participation and engagement in the activity.
B. An outdoor concert: While an outdoor concert can be entertaining, it may not actively engage wheelchair-bound residents. They may be limited in their ability to fully participate and interact with others during the concert.
D. A tea party in the courtyard: While a tea party can be a pleasant social activity, it may not provide the desired physical engagement for wheelchair-bound residents. They may require activities that involve more movement and physical participation.
