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. The 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"]
The concentration of cefazolin after reconstitution can be calculated as follows: Concentration = Total amount of drug / Total volume after reconstitution
Since the available vial contains 1 gram (1000 mg) of cefazolin and the total volume after reconstitution is 2.5 mL, we can calculate the concentration:
Concentration = 1000 mg / 2.5 mL = 400 mg/mL
Therefore, after reconstitution, the concentration of cefazolin is 400 mg/mL.
To administer a dose of 400 mg, we divide the desired dose by the concentration: Volume to administer = Desired dose / Concentration
Volume to administer = 400 mg / 400 mg/mL = 1 mL

Correct Answer is A
Explanation
The prescription for Ampicillin 500 mg PO q8h means that the client should take 500 mg of Ampicillin orally every 8 hours. "PO" stands for "by mouth," indicating that the medication should be taken orally. The medication is prescribed at 1000, and the next dose is due at 1300 (1:00 PM).
The other options are as follows:
B. Lisinopril 5 mg PO every day: This medication is prescribed to be taken once a day, not every 8 hours. It is not due at 1300.
C. Metformin 1000 mg PO BID: This medication is prescribed to be taken twice a day (BID), but it is not due at 1300. The timing for the next dose depends on when the first dose was administered.
D. Pantoprazole 40 mg PO every day: This medication is also prescribed to be taken once a day, not every 8 hours. It is not due at 1300.
