A nurse is preparing to administer cefazolin 500 mg IM to a client. Available is cefazolin powder 500 mg vial. After reconstitution, the concentration available is cefazolin 330 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["1.5"]
The nurse should administer 1.5 mL of cefazolin solution.
Here's the calculation:
Desired dose: 500 mg
Concentration after reconstitution: 330 mg/mL
We can find the volume to administer by dividing the desired dose by the concentration and rounding to the nearest tenth:
Volume to administer (rounded to nearest tenth) = Dose / Concentration
= 500 mg / 330 mg/mL
= 1.5 mL (rounded to nearest tenth)
Therefore, the nurse should administer 1.5 mL of the reconstituted cefazolin solution.

Explanation
To calculate the correct dose of bumetanide, we need to follow these steps:
-
Determine the desired dose per tablet:
- Each tablet contains 0.5 mg of bumetanide.
-
Calculate the number of tablets needed per dose:
- Divide the desired dose (5 mg) by the dose per tablet (0.5 mg):
- 5 mg / 0.5 mg/tablet = 10 tablets
- Divide the desired dose (5 mg) by the dose per tablet (0.5 mg):
Therefore, the nurse should administer 10 tablets of bumetanide per day.
Answer: 10 tablets
Correct Answer is D
Explanation
D. Dose/strength:
This is the correct option. The prescription lacks specific information about the dose or strength of the medication. Fluocinolone comes in various strengths (e.g., 0.025%, 0.05%, etc.), and it is crucial for the nurse to know the exact dose to administer. Therefore, the nurse should ask the provider to add the strength or dose of fluocinolone cream to the prescription to ensure safe and accurate administration.
