A nurse is preparing to administer 1g of cefazolin IM. The nurse reconstitutes a 1g vial of cefazolin with sterile water to yield a final concentration of 330 mg/mL. How many mL should the nurse administer?
The Correct Answer is ["3.03 "]
The nurse should administer 3.03 mL of cefazolin. Here’s the calculation: Step 1: The total dosage required is 1g.
Step 2: Each mL of the reconstituted solution contains 330 mg of cefazolin. Step 3: So, the volume to be administered is 1000 mg ÷ 330 mg/mL = 3.03 mL.

Correct Answer is ["1000 "]
Explanation
Step 1 is to calculate the total volume to be infused in mL/hr. This is done by dividing the total volume (250 mL) by the time in hours (15 min ÷ 60 min/hr). So, 250 mL ÷ (15 min ÷ 60 min/hr) = 1000 mL/hr.
So, the correct answer is 1000 mL/hr.
Correct Answer is ["14 "]
Explanation
The medication should be discarded 14 days after reconstitution. This is a standard guideline for most reconstituted medications to ensure potency and prevent bacterial growth.
