EXAM OVERVIEW
This Midterm Exam covers foundational concepts from Weeks 1-12 of the AORN Periop 101 curriculum,
including sterile technique, patient safety, surgical zones, Universal Protocol, and basic perioperative nursing
principles.
QUESTION 1
Which organization writes the Standards of Perioperative Nursing?
A) The Joint Commission
B) Association of periOperative Registered Nurses (AORN)
C) Centers for Medicare and Medicaid Services (CMS)
D) American Nurses Association (ANA)
Correct Answer: B
Rationale: The Association of periOperative Registered Nurses (AORN) writes the Standards of Perioperative
Nursing. AORN develops evidence-based guidelines that define the standards of practice for perioperative
nursing and provide guidance for quality patient care in the surgical setting. The Joint Commission accredits
healthcare organizations, CMS administers Medicare/Medicaid, and ANA represents all registered nurses.
QUESTION 2
What term means "the duty to do no harm"?
A) Beneficence
B) Nonmaleficence
C) Justice
D) Autonomy
Correct Answer: B
,2
Rationale: Nonmaleficence is the ethical principle meaning "the duty to do no harm." It is one of the four core
principles of bioethics along with beneficence (doing good), autonomy (respecting patient's right to choose),
and justice (fairness in healthcare distribution). Nonmaleficence is fundamental in perioperative nursing.
QUESTION 3
Which organization determines the scope of practice for RNs in each state?
A) American Nurses Association
B) State Board of Nursing
C) The Joint Commission
D) Centers for Medicare and Medicaid Services
Correct Answer: B
Rationale: The State Board of Nursing determines the scope of practice for RNs in each state through the
Nurse Practice Act. Each state has its own Board of Nursing that regulates nursing practice within that state.
The Nurse Practice Act defines the legal scope of practice, educational requirements, and standards for
nursing in that jurisdiction.
QUESTION 4
What is the correct definition of respondeat superior?
A) An employer's responsibility for the RN when the RN acts within the scope of nursing practice
B) The nurse's responsibility to report unsafe conditions
C) The patient's right to refuse treatment
D) The surgeon's authority over the OR team
Correct Answer: A
Rationale: Respondeat superior means "let the master answer." This legal doctrine holds employers vicariously
liable for the actions of employees performed within the scope of their employment. If a perioperative nurse
acts within their scope of practice and an error occurs, the employer may be held responsible. This emphasizes
the importance of working within one's defined scope.
QUESTION 5
The patient's hair should be covered before entering which zone?
,3
A) Semi-restricted zone
B) Unrestricted zone
C) Restricted zone
D) All zones
Correct Answer: C
Rationale: Hair should be covered before entering the restricted zone, where surgery is performed and sterile
supplies are opened. This is a key infection prevention measure to reduce the risk of microbial contamination
from shedding hair. The restricted zone requires full surgical attire including head coverings, masks, and
appropriate footwear. In semi-restricted zones, hair must also be covered, but the restricted zone has the
strictest requirements.
QUESTION 6
When applying the concept of surgical conscience, which statements should be considered? (Select all that
apply.)
A) It involves mental discipline and the ability to speak out
B) It is essential to the delivery of optimal care and prevent harm
C) It allows for occasional compromise in aseptic technique when time is short
D) Surgical conscience allows for no compromise in the principles of aseptic technique
Correct Answer: A, B, D
Rationale: Surgical conscience is the ethical and professional commitment to maintaining aseptic technique at
all times. It involves mental discipline, speaking out when a breach occurs, and never compromising
principles—even when no one is watching. It does NOT allow for compromise, even when time is short, as
any breach in aseptic technique can lead to surgical site infections.
QUESTION 7
The Joint Commission Universal Protocol consists of which of the following?
A) Preoperative verification
B) Surgical site marking
C) Time Out
D) All of the above
, 4
Correct Answer: D
Rationale: The Universal Protocol has three components: 1) preoperative verification of
patient/procedure/site, 2) marking the operative site, and 3) performing a Time Out immediately before
incision. These steps are designed to prevent wrong-site, wrong-procedure, and wrong-person surgery. All
three components are required for every surgical procedure.
QUESTION 8
Which of the following is a physical hazard in the OR?
A) Fire
B) Electrical shock
C) Falls
D) All of the above
Correct Answer: D
Rationale: Physical hazards in the OR include fire (from electrosurgical units, lasers, and flammable prep
solutions), electrical shock from equipment, and falls from patient transfers or slippery floors. The OR
environment contains numerous potential physical hazards that must be managed through proper training,
equipment maintenance, and safety protocols.
QUESTION 9
What is the ideal temperature and humidity range for the operating room environment?
A) Temperature: 65-70°F, Humidity: 50-60%
B) Temperature: 68-73°F, Humidity: 50-70%
C) Temperature: 70-75°F, Humidity: 40-50%
D) Temperature: 60-65°F, Humidity: 30-40%
Correct Answer: B
Rationale: The ideal operating room temperature is 68-73°F (20-23°C) with humidity between 50-70%. This
range helps control microbial growth, maintain patient normothermia, and ensure staff comfort while
working in full surgical attire. Humidity below 50% increases the risk of static electricity and equipment
malfunctions; humidity above 70% promotes microbial growth.
