Postoperative Procedures - Domain Overview
Postoperative Procedures (POSTOP) covers the tasks that occur at the conclusion of a procedure and immediately afterward: dressing the wound, managing drains, finalizing specimen disposition, turning over the room, beginning instrument decontamination, and safely transferring the patient. It accounts for approximately 6.7% of the CST exam (10 of 150 scored items).
What This Domain Covers
- Dressing selection and application - primary, secondary, pressure, and occlusive dressings.
- Drain types and management, including open (Penrose) and closed-suction (Jackson-Pratt, Hemovac) systems.
- Specimen disposition and final documentation.
- Room turnover - between-case cleaning vs. terminal cleaning.
- Point-of-use instrument treatment before transport to sterile processing.
- Safe patient transfer and structured handoff communication to PACU.
Why POSTOP Matters in Practice
The moments immediately after a procedure carry their own risks - inadequate wound protection, drain mismanagement, incomplete handoff communication - that can undermine an otherwise well-executed surgery. This domain tests whether you understand that patient safety responsibility does not end when the last stitch is placed.
