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. 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"]
This is the correct answer because the concentration of cefazolin after reconstitution is 1 gram/2.5 mL, which is equivalent to 400 mg/1 mL. Therefore, to administer 400 mg of cefazolin, the PN should draw up 1 mL of the reconstituted solution. This can be calculated using the formula:
Desired dose / Available dose = Volume to administer
400 mg / 1000 mg = x mL / 2.5 mL
x = (400 x 2.5) / 1000
x = 1 mL

Correct Answer is D
Explanation
Step 1: Convert the child's weight from pounds to kilograms.
55 pounds ÷ 2.2 lbs/kg = 25 kg
Step 2: Calculate the total daily dose using the child's weight and the prescribed dosage.
25 kg × 150 mg/kg/day = 3750 mg/day
The nurse should administer 3750 mg of cefotaxime each day.
Correct Answer is D
Explanation
Choice A rationale:
Assigning the newly hired unlicensed assistive personnel (UAP) to clients who require the least complex level of care is not the best approach to ensure adequate care for all clients. It may limit the UAP's opportunities for learning and growth and may not fully utilize their skills.
Choice B rationale:
Asking the most experienced UAP to partner with the newly hired UAP is a reasonable approach, but it may not provide a comprehensive solution. It can be beneficial for mentorship and guidance, but it may not address all the clients' needs efficiently.
Choice C rationale:
Reviewing the UAP's skills checklist and experience with the person who hired the UAP is an important step in assessing competency. However, it alone may not ensure adequate care for all clients. Competency assessment should be ongoing and include direct observation of care delivery.
