System-Specific Assessments

Stage 6 — Evaluate outcomes. Review the clinical, antimicrobial, prevention, and surveillance timeline and answer the three outcome questions.

Choose your responses, then check the answer.

TimeData
Postoperative day 5, 0700 — RecognitionNew fever, tachycardia, leukocytosis, purulent drainage, expanding erythema, and increasing tenderness trigger focused assessment, surgical notification, and evaluation for sepsis and deeper complication. A fresh dressing contains the drainage, so Standard Precautions are used with a plan to add Contact Precautions if containment fails.
Postoperative day 5, 0930 — Source controlThe surgeon opens and drains the superficial collection and obtains an aseptic wound specimen. Blood cultures are obtained because the systemic assessment raises bacteremia concern. CT shows no leak, deep fascial process, or organ-space collection. Site- and severity-directed empiric therapy begins without avoidable delay.
Postoperative day 6 — Microbiology and refinementThe wound specimen grows MRSA without a gram-negative or anaerobic pathogen; blood cultures remain negative. Broad colorectal-site empiric agents are narrowed to susceptibility-directed therapy. Route, monitoring, and duration are selected from source control, infection depth, kidney function, and clinical response.
Postoperative day 7 — Clinical responseTemperature is 36.9 C, heart rate 82/min, WBC 10.9 x 10^9/L, pain 2/10, erythema has receded inside the marked border, and drainage is scant and contained. Glucose is managed by the inpatient protocol without hypoglycemia. Ordered wound care and discharge teaching continue.
Quality and surveillance review — Separate pathwayInfection prevention applies current NHSN criteria and the facility reporting plan. The quality team verifies prophylaxis selection and timing, discontinuation after closure, skin preparation, normothermia, and perioperative glucose below 200 mg/dL, assigning owners and remeasurement dates without naming one process variance as the cause.

Q1. Which finding set best demonstrates that the immediate clinical response is effective?

Q2. Which antimicrobial interpretation is most accurate?

Q3. Which quality and surveillance response is appropriate?

Explanation
Outcome evaluation
The response is effective because source control occurs promptly, drainage becomes contained, fever and leukocytosis resolve, erythema recedes, pain decreases, and broad empiric therapy is narrowed from microbiology and clinical response. Negative blood cultures do not erase the wound infection. Prevention review and NHSN classification remain separate from treatment: the team verifies prophylaxis, skin preparation, temperature, and glucose processes, assigns owners, and applies current surveillance criteria without claiming one variance caused the SSI. If prolonged IV vancomycin is truly needed for serious MRSA infection, AUC-guided monitoring is preferred to a universal trough-only target.
