Zinacef 750 mg IV q 8h is ordered. This would be what type of intravenous infusion?

A. KVO: "Keep vein open" infusions are minimal-rate fluids used to maintain IV line patency, not to deliver active medications like Zinacef. This does not apply to scheduled antibiotic therapy. B. therapeutic: Zinacef (cefuroxime) is an antibiotic used to treat infections. Since it is being administered on a scheduled basis (750 mg IV q8h), it is used therapeutically to manage a medical condition. C. replacement: Replacement fluids are used to restore lost fluids and electrolytes due to vomiting, diarrhea, bleeding, or other losses. They are not used for medication administration. D. maintenance: Maintenance fluids meet basic daily fluid and electrolyte requirements in patients unable to eat or drink. They do not involve scheduled doses of antibiotics or other medications.
