2. Surgical Anatomy and Physiology
3. Perioperative Pharmacology and Anesthesia
4. Surgical Instrumentation and Equipment
5. Patient Safety and Positioning
6. Wound Healing and Hemostasis

Introduction
This comprehensive assessment is designed to evaluate the perioperative nurse's mastery of essential
knowledge and clinical judgment required for safe and effective patient care in the surgical setting.
The examination covers foundational theory, applied clinical skills, regulatory compliance, ethical
decision-making, and critical thinking across the perioperative continuum. Through a combination of
multiple-choice questions and scenario-based items, candidates will demonstrate their ability to apply
evidence-based practice, prioritize patient safety, and manage complex situations encountered in the
operating room. This assessment emphasizes real-world application, requiring the integration of
technical knowledge with professional standards to ensure optimal patient outcomes. Successful
completion reflects readiness for independent perioperative nursing practice.
SECTION ONE: QUESTIONS 1-100
1. What is the primary purpose of the surgical skin prep?
A. To remove all microorganisms from the skin
B. To reduce the number of microorganisms to a safe level
C. To sterilize the surgical site
D. To provide anesthesia to the skin
🟢B
🔴 Explanation: Surgical skin preparation aims to reduce the number of microorganisms on the
skin to minimize the risk of surgical site infection. It does not sterilize the skin, as complete
elimination of all microorganisms is not possible.
,2. Which type of surgical wound is classified as clean-contaminated?
A. An incision made under sterile conditions without entering a hollow organ
B. An incision made under sterile conditions that enters the respiratory tract
C. A traumatic wound with devitalized tissue
D. A wound with purulent drainage
🟢B
🔴 Explanation: Clean-contaminated wounds involve entry into a hollow organ under controlled
conditions, such as the respiratory, gastrointestinal, or genitourinary tract, without significant
spillage.
3. What is the appropriate action when a surgical team member notices a break in sterile
technique?
A. Ignore the break to avoid alarming the team
B. Correct the break immediately and report it
C. Wait until the procedure is complete to address it
D. Document the break without intervention
🟢B
🔴 Explanation: Any break in sterile technique must be corrected immediately to maintain the
integrity of the sterile field and prevent infection. The perioperative nurse must advocate for patient
safety by addressing the issue promptly.
4. Which of the following is a late sign of malignant hyperthermia?
A. Muscle rigidity
B. Tachycardia
C. Hypercarbia
D. Dark brown urine
🟢D
🔴 Explanation: Dark brown urine indicates myoglobinuria, a late sign of malignant hyperthermia
resulting from muscle breakdown. Early signs include muscle rigidity, tachycardia, and hypercarbia.
5. The primary method of heat loss in the operating room is:
A. Radiation
B. Convection
C. Evaporation
D. Conduction
, 🟢A
🔴 Explanation: Radiation is the primary method of heat loss in the OR, as the patient's body loses
heat to cooler surrounding surfaces. Convection, evaporation, and conduction also contribute but
to a lesser degree.
6. What is the normal range for intracranial pressure (ICP)?
A. 0-5 mmHg
B. 5-15 mmHg
C. 15-25 mmHg
D. 25-35 mmHg
🟢B
🔴 Explanation: Normal intracranial pressure ranges from 5 to 15 mmHg. Pressures above 20
mmHg are considered elevated and require intervention.
7. Which positioning device is used to protect the brachial plexus during lateral positioning?
A. Axillary roll
B. Headrest
C. Arm board
D. Stirrups
🟢A
🔴 Explanation: An axillary roll is placed under the dependent axilla during lateral positioning to
prevent compression of the brachial plexus and neurovascular structures.
8. The surgical count includes which of the following items?
A. Sponges, needles, and instruments only
B. Sponges, needles, instruments, and sharps
C. Sponges, needles, instruments, and drapes
D. Sponges, instruments, and sutures only
🟢A
🔴 Explanation: The surgical count includes sponges, needles, and instruments. Sharps are counted
as part of the needle count, and drapes are not typically counted items.
9. What is the mechanism of action of propofol?
