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:
Washing the patient's left side first and then moving to the right side does not demonstrate an individualized approach or consideration for the patient's preferences and abilities. It is important to involve the patient in the decision-making process, especially when they have hemiparesis, to promote their autonomy and comfort.
Choice B rationale:
Washing the patient's right side first and then moving to the left side does not consider the patient's preference and may not align with their abilities or comfort. It is essential to prioritize the patient's preferences and needs.
Choice C rationale:
Washing both sides of the patient at the same time, starting from the head and moving down, may not be feasible or comfortable for the patient, especially if they have hemiparesis. This approach does not demonstrate an individualized care plan based on the patient's specific condition.
Choice D rationale:
Asking the patient which side they prefer to wash first and then following their preference is the most patient-centered and appropriate approach. This approach respects the patient's autonomy and ensures that their needs and comfort are prioritized during the bathing process. It allows for individualized care based on the patient's abilities and preferences.
