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 ["0.7 "]
Explanation
Step 1 is to calculate the volume of midazolam to administer. Given that the available midazolam is 5 mg/mL and the nurse needs to administer 0.07 mg/kg to a patient who weighs 50 kg, the calculation is as follows: (0.07 mg/kg × 50 kg) ÷ 5 mg/mL = 0.7 mL3
