Certified Surgical Technologist Certified Surgical Technologist MCQ 4 — Questions and Answers
Question 1: Which type of wound healing occurs when wound edges are approximated and closed primarily with sutures?
- Healing by secondary intention
- Healing by tertiary intention
- Healing by primary intention (Correct answer)
- Granulation healing
Correct answer: Healing by primary intention
Primary intention healing occurs when clean wound edges are surgically approximated, minimizing scar formation and healing time.
Question 2: During an open appendectomy, which incision is most commonly used?
- Midline laparotomy
- Pfannenstiel incision
- McBurney's incision (Correct answer)
- Kocher incision
Correct answer: McBurney's incision
McBurney's incision (oblique muscle-splitting) is made at McBurney's point in the right lower quadrant for direct access to the appendix.
Question 3: A scrub technologist notices a package with a compromised seal on the sterile field. The correct action is to:
- Use the item quickly before contamination spreads
- Cover it with a sterile drape and proceed
- Remove it from the sterile field and obtain a new sterile item (Correct answer)
- Inspect the item visually and use it if it appears clean
Correct answer: Remove it from the sterile field and obtain a new sterile item
Any item with a compromised package seal must be considered non-sterile and immediately removed from the sterile field.
Question 4: Which anatomical structure must be identified and protected during a radical mastectomy to preserve arm function?
- Brachial artery
- Long thoracic nerve (Correct answer)
- Ulnar nerve
- Radial nerve
Correct answer: Long thoracic nerve
The long thoracic nerve innervates the serratus anterior muscle; injury causes 'winged scapula' and loss of arm elevation.
Question 5: Ethylene oxide (EO) gas sterilization is best suited for which type of surgical item?
- Metal instruments that tolerate heat
- Delicate heat-sensitive instruments and endoscopes (Correct answer)
- Linen drapes and gowns
- Saline irrigation solution
Correct answer: Delicate heat-sensitive instruments and endoscopes
EO gas sterilizes at low temperatures, making it ideal for heat-sensitive items such as flexible endoscopes and delicate powered instruments.
Question 6: During a cesarean section (C-section), which layer is opened last immediately before entering the uterus?
- Skin
- Rectus fascia
- Vesicouterine peritoneum (bladder flap) (Correct answer)
- Rectus muscle
Correct answer: Vesicouterine peritoneum (bladder flap)
The vesicouterine peritoneum is incised and the bladder reflected inferiorly just before the uterine incision to protect the bladder.
Question 7: Which OSHA standard specifically governs occupational exposure to bloodborne pathogens in the surgical setting?
- 29 CFR 1910.132 (Personal Protective Equipment)
- 29 CFR 1910.1030 (Bloodborne Pathogens Standard) (Correct answer)
- 29 CFR 1910.1200 (Hazard Communication)
- 29 CFR 1910.147 (Lockout/Tagout)
Correct answer: 29 CFR 1910.1030 (Bloodborne Pathogens Standard)
OSHA's Bloodborne Pathogens Standard (29 CFR 1910.1030) requires engineering controls, PPE, and exposure plans to protect workers from blood and body fluids.
