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).

Answer and Explanation

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 ["30"]

Explanation

Question: How many mL/hour should the nurse program the infusion pump?

Step 1: Convert 176 pounds to kg. 176 lbs ÷ 2.2 = 80 kg

Step 2: Calculate the total mcg per hour. 2 mcg/min × 60 min = 120 mcg/hour

Step 3: Convert mcg to mg. 120 mcg ÷ 1000 = 0.12 mg

Step 4: Calculate the mL/hour. 0.12 mg ÷ (4 mg ÷ 1000 mL) = 30 mL/hour

Answer: 30 mL/hour
