Explanation & Rationale
i) Prophylactic: The cefazolin administered prior to the colonoscopy was intended to prevent potential infection related to the surgical procedure. Prophylactic antibiotics are given to reduce the risk of postoperative infections in patients undergoing surgeries, especially those involving the gastrointestinal tract. ii) Empiric: The ampicillin/sulbactam prescribed post-procedure is used empirically to treat the diverticular abscess while awaiting culture results. Empiric therapy is based on clinical judgment to target likely pathogens before specific culture data are available, ensuring timely treatment of the infection. Incorrect: Curative: Refers to treatment aimed at eradicating a disease, not applicable to the initial prophylactic dose or empirical use of antibiotics. Therapeutic: Broadly refers to treatment, but in this context, "empiric" more precisely describes the rationale for antibiotic use. Diagnostic: Involves tests or procedures to determine a diagnosis, not relevant to the use of antibiotics. Adjunctive: Refers to supplementary treatment, which does not describe the primary role of the antibiotics. Maintenance: Involves ongoing treatment to prevent recurrence, which is not relevant here.
