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).

Answer and Explanation

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

A. C-reactive protein level:
C-reactive protein (CRP) is a marker of inflammation but does not specifically identify the causative organism of an infection. While elevated CRP can suggest infection or inflammation, it doesn't provide the necessary information for treatment.

B. Serum blood glucose (BG) level:
Serum blood glucose levels are important to monitor in diabetic patients because high glucose levels can impair healing and increase the risk of infection. However, it does not directly help identify the causative organism in this situation.

C. Serum albumin:
Serum albumin reflects nutritional status and can indicate malnutrition or poor wound healing. While it may be relevant for healing, it is not the most immediate test to evaluate for infection.

D. Culture for sensitive organisms:
Given the red, swollen wound with drainage and foul odor, a wound culture is the most appropriate first step to identify the specific infectious organism. This will guide the healthcare provider in selecting the most appropriate antibiotic treatment.

A. Consult with the charge nurse about implementing suicide precautions. B. Sit quietly in the client's room until the client is ready to verbalize his feelings. C. Notify a member of the client's family of the need to come stay with the client. D. Leave the room after oﬀering to return to the client's room at a later time. E. Leave the room after oﬀering to return to the client's room at a later time.

Correct Answer is D

Explanation

This is the action that the PN should implement for a male client who has just been told he has cancer and asks to be left alone. Leaving the room after oﬀering to return later respects the client's autonomy and privacy, while also showing empathy and availability. The client may need some time and space to process the diagnosis and cope with his emotions. The PN should not force the client to talk or stay with him if he does not want to, but should also not abandon him or ignore his needs.
