CST POSTOP Study Guide - Postoperative Procedures

A complete NBSTSA CST study guide for the Postoperative Procedures domain: dressings, drains, specimen disposition, room turnover, and instrument decontamination.

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.

Frequently Asked Questions

What percentage of the CST exam is POSTOP?

Postoperative Procedures makes up approximately 6.7% of the exam, or 10 of the 150 scored questions.

How does POSTOP connect to other domains?

POSTOP content builds directly on INTRA concepts like specimen handling and wound classification, applied at the end-of-case stage.

What is the most commonly confused POSTOP topic?

Open vs. closed drain systems, and between-case vs. terminal cleaning, are the two most frequently confused topic pairs in this domain.
