A client receives new prescriptions at 1000 that include discontinuing IV fluids and IV antibiotics. Which prescription should the practical nurse (PN) administer at 1300?

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.
