✍️ Sample CST Questions & Answers

1. Which statement best describes the surgical technologist's ethical obligation regarding a patient who is under general anesthesia?
The scrub tech has a heightened advocacy duty because the patient is unable to speak for themselves

Because an anesthetized patient cannot self-advocate, every team member—including the scrub tech—has an increased ethical responsibility to act in the patient's best interest.

2. When assembling a tray for a procedure requiring magnification, the scrub technician should include which type of instruments?
Micro-instruments with smooth, fine-tipped jaws

Microsurgery requires delicate micro-instruments with fine tips capable of handling tiny structures without crushing or tearing.

3. A keloid scar differs from a hypertrophic scar in that a keloid:
Extends beyond the original wound borders into surrounding tissue

Keloids are abnormal scar formations that extend beyond the original wound margins into adjacent normal tissue, unlike hypertrophic scars which stay within wound boundaries.

4. Proper instrument passing technique during surgery is important for efficiency because:
Anticipating the surgeon's needs and passing instruments decisively reduces hesitation and operative time

Confident, anticipatory instrument passing keeps the operative tempo high and minimizes the surgeon's distraction between maneuvers.

5. When a surgical technologist is asked to perform a task outside their training, the correct response is to:
Decline and explain it exceeds their scope of practice

A CST must refuse tasks outside their scope of practice to protect patient safety and maintain professional standards.

6. The term 'block scheduling' in OR management refers to:
Reserving OR time in defined blocks for specific surgeons or service lines to improve predictability

Block scheduling allocates reserved OR time to specific surgeons or specialties, improving case volume predictability and resource planning.
