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 A
Explanation
The appropriate action for the practical nurse (PN) in this situation would be to ask the client if he is currently hearing voices. This step is important to assess the client's current state and gather information about his experiences. By directly asking the client about hearing voices, the PN can gain insight into the client's symptoms and determine if there is a need for further intervention or support.
B. Having the unlicensed assistive personnel (UAP) escort the client to his room may not be necessary at this point, as the client may simply be engaging in self-talk or may prefer some time alone. However, if the client's behavior becomes disruptive, agitated, or poses a safety risk, involving the UAP or taking other appropriate measures may be warranted.
C. Recording the event is important for documentation purposes, but it should not be the only action taken. It is crucial to actively assess the client's well-being and address any potential concerns or needs.
D. Administering an as-needed (PRN) dose of haloperidol without further assessment or consulting the healthcare provider would be inappropriate. Medication decisions should be based on a comprehensive evaluation of the client's symptoms and the healthcare provider's recommendations.
Correct Answer is C
Explanation
A callus is a normal response of the body during bone healing, where new bone tissue forms around the fracture site to provide stability and support. It helps in the process of bridging the fracture and promoting healing.
The PN can provide reassurance to the client by explaining that the presence of a callus indicates that the bone is healing and progressing toward recovery. It is important to educate the client about the expected timeline for bone healing and the need for continued follow-up with the healthcare provider.
Incorrect:
A. Prepare to assist in applying a new cast to reduce pressure points: This choice assumes that the client's concern is related to discomfort or pressure points caused by the current cast.
However, the client's concern is about the formation of a callus, which is a normal part of bone healing. There is no indication that a new cast is necessary at this point.
B. Report the client's concern to the healthcare provider: While it's important to address client concerns and communicate any changes in their condition to the healthcare provider, in this case, the formation of a callus is an expected part of the bone healing process. It is not necessary to report this concern to the healthcare provider as it is a normal occurrence.
D. Teach the client strategies to prevent further calluses: The formation of a callus in this context is a natural response of the body to promote bone healing. It is not necessary to teach the client strategies to prevent further calluses, as callus formation is a temporary and beneficial part of the healing process.
