Full Case Simulations and Clinical Readiness Assessment

What This Lesson Asks of You

This is your capstone practice session for the OR Clinicals: Scrub Role course. You will independently perform two full simulated surgical cases drawn at random. No instructor coaching is available once the clock starts. Every action you take — from the moment you open the first sterile package to the moment you hand off the last specimen — is observed, documented, and scored. This lesson describes what is expected, why each piece matters, and how to carry yourself through both cases with confidence and safety.

The Ten-Minute Case Review

When you draw your specialty case card, you have ten minutes to read and plan. Use every second. Identify the procedure, the position, the expected instrument sets, the suture preferences, and any specialty items such as implants or powered equipment. Mental rehearsal during this window reduces hesitation on the floor. Confirm in your mind the order of events: patient positioning, draping sequence, the initial count, the first instrument pass, and the specimen-handling plan. A focused ten-minute review is a professional habit, not a shortcut.

Setting Up Without Assistance

Independent sterile setup is the first scored phase. Open all packaging using correct aseptic technique: check expiration dates, inspect packaging integrity, and open wrappers away from the sterile field. Arrange your back table and Mayo stand in a logical, reproducible order — instruments grouped by function, sharps accounted for and contained, sutures organized by size and type. The sterile field must be maintained throughout. Never reach across a sterile field, never turn your back to it, and never allow an unsterile item or person to contact it. These are not guidelines; they are the non-negotiable foundation of patient safety in the perioperative environment.

Performing the Scrub Role During the Case

Once the simulated case begins, you function as the scrub surgical technologist. Your duties fall into several categories.

Counts. Sponge, sharps, and instrument counts are performed with the circulator (instructor or lab assistant) at the required intervals: before the procedure begins, before closure of any body cavity, before wound closure begins, and at skin closure. Counts must be concurrent, audible, and documented on the count record. A discrepancy is a patient-safety event. If a count does not reconcile, announce it immediately and follow the facility protocol — never assume an item will turn up on its own.

Passing instruments. Anticipate the surgeon's next move. Pass instruments in a controlled, functional manner — handles toward the surgeon, cutting edges away from hands. Sharps are passed using a neutral zone or hands-free technique whenever possible. A needle or blade that travels hand-to-hand increases the risk of percutaneous injury to both team members. This is an area where a single unsafe event will result in an automatic failure of the case.

Specimen handling. When tissue, fluid, or foreign material is removed, it becomes a specimen with a legal and diagnostic chain of custody. Receive it onto the sterile field without contaminating it, place it in the correct container, and label it accurately using the information confirmed with the surgeon. Complete the specimen requisition form. Never leave a specimen unlabeled or unattended.

Implant documentation. If your assigned case involves an implant, record the manufacturer, lot number, and device identification on the implant log. This documentation supports product traceability and patient recall procedures.

After Both Cases: Self-Assessment

Professional growth requires honest self-evaluation. After the simulation ends, you complete a self-assessment form identifying two specific strengths and two specific areas for continued development. Vague answers such as "I did well" or "I need to improve" are not acceptable. Reference concrete actions: the moment a count was called, how a suture was loaded, the way a specimen was labeled. This document becomes part of your lab log and is submitted as part of the assessment.

How You Will Be Scored

The instructor scores each case on a 50-point rubric covering setup, sterile technique, counts, instrument passing, specimen handling, communication, and documentation. You must average 40 out of 50 points across both cases. There must be no critical sterile field violations on either case and no unsafe sharp events on either case. These two conditions are independent of your point total — a violation on either disqualifies the attempt regardless of score. Students who do not meet the standard receive targeted remediation addressing the specific deficient areas and are given one retest opportunity.

Connecting This to the CST Credential

The National Board of Surgical Technology and Surgical Assisting (NBSTSA) Certified Surgical Technologist (CST) examination tests your ability to apply knowledge across the full perioperative continuum, including intraoperative skills, sterile technique, counts, and specialty procedures. Every task in this simulation maps to content domains on that examination. Performing well here means you have demonstrated, under realistic conditions, the integrated competence the credential is designed to certify.
