WITH COMPLETE QUESTIONS AND CORRECT
DETAILED ANSWERS (VERIFIED ANSWERS) |ALREADY
GRADED A+
1. Which action is the highest priority during preoperative patient verification?
A. Confirming insurance coverage
B. Verifying the patient's identity using two identifiers
C. Reviewing the surgeon's schedule
D. Assessing operating room availability
Correct Answer: B
Rationale: Using at least two patient identifiers helps prevent wrong-patient procedures and is a
critical patient safety requirement.
2. Which microorganism is most resistant to standard sterilization processes?
A. Vegetative bacteria
B. Fungi
C. Viruses
D. Bacterial spores
Correct Answer: D
Rationale: Bacterial spores are highly resistant and are used in biological indicators to monitor
sterilization effectiveness.
3. When opening a sterile package, the circulator should open the flap:
A. Closest to the body first
B. Farthest from the body first
,C. Left side first
D. Right side first
Correct Answer: B
Rationale: Opening the farthest flap first reduces the risk of contaminating the sterile contents.
4. Which action by a scrub person would require immediate correction?
A. Keeping hands above waist level
B. Facing the sterile field
C. Reaching across an unsterile area
D. Maintaining sterile attire
Correct Answer: C
Rationale: Reaching across an unsterile area can contaminate the sterile field and must be
corrected immediately.
5. What is the primary purpose of electrosurgical grounding pads (dispersive electrodes)?
A. Increase surgical speed
B. Reduce bleeding only
C. Safely return electrical current to the generator
D. Improve patient positioning
Correct Answer: C
Rationale: The dispersive electrode provides a safe pathway for electrical current, reducing the
risk of burns.
6. Which patient is at the highest risk for developing a surgical site infection (SSI)?
A. Healthy young adult undergoing a 30-minute procedure
B. Patient with uncontrolled diabetes undergoing abdominal surgery
C. Patient receiving local anesthesia for a skin biopsy
D. Healthy athlete undergoing arthroscopy
Correct Answer: B
, Rationale: Diabetes, especially when poorly controlled, increases susceptibility to infection and
delays wound healing.
7. During skin preparation, the antiseptic solution should generally be applied:
A. From the incision site outward in a circular motion
B. From the outer edges toward the center
C. Randomly over the surgical area
D. Only directly over the incision site
Correct Answer: A
Rationale: Prepping from the cleanest area (incision site) outward helps prevent bringing
microorganisms into the surgical site.
8. Which of the following is considered a mechanical indicator of sterilization?
A. Biological spore test
B. Chemical indicator strip
C. Time, temperature, and pressure readings
D. Culture report
Correct Answer: C
Rationale: Mechanical indicators include the sterilizer's physical parameters such as time,
temperature, and pressure.
9. A patient undergoing surgery suddenly develops signs of malignant hyperthermia.
Which medication should be administered immediately?
A. Epinephrine
B. Atropine
C. Dantrolene
D. Lidocaine
Correct Answer: C
Rationale: Dantrolene is the drug of choice for malignant hyperthermia and should be
administered promptly to reduce mortality.
