POSTOP Domain Overview
Postoperative Procedures is a smaller domain, accounting for roughly 6.7% of the CST exam (10 of 150 scored items). It covers dressing application, drain management, specimen disposition, room turnover, instrument decontamination, and safe patient transfer.
What to Study First
- Dressing types and purpose - primary vs. secondary, pressure, occlusive, and nonadherent dressings, and when each is used.
- Drain types - open vs. closed systems, and the mechanism (gravity, suction) each relies on.
- Room turnover sequence - the difference between between-case cleaning and terminal cleaning.
- Point-of-use instrument treatment - what happens to instruments immediately after the case, before they reach sterile processing.
- Safe patient transfer and handoff communication - protecting the airway, lines, and surgical site during transfer to PACU.

Question Strategy
- Because this is a small domain, do not over-invest study time relative to its exam weight - master the core workflow, then move on.
- POSTOP questions often connect back to INTRA concepts (wound classification, specimen handling) applied at the end-of-case stage - review both domains together for stronger retention.
- Drain-type questions test mechanism (suction vs. gravity) more than brand names - understand how each drain actually works.
Common Traps to Avoid
- Confusing between-case cleaning (routine, every patient) with terminal cleaning (thorough, end-of-day).
- Forgetting that instruments must be kept moist at the point of use to prevent bioburden from hardening before decontamination.
- Underestimating the importance of structured handoff communication - incomplete handoffs are a recognized patient safety risk.
