[SECTION 1: Preoperative Preparation & Patient Care — Questions 1-30]
Q1: During the preoperative patient assessment, the surgical technologist notes the patient has a
documented latex allergy. Which of the following actions is MOST critical to prevent an allergic
reaction in the operating room?
A. Use only powder-free latex gloves.
B. Ensure all supplies in the room are latex-free, including drainage tubes and stopcocks.
C. Administer an antihistamine preoperatively.
D. Place a "Latex Allergy" sticker on the front of the patient's chart only.
Correct Answer: B
Rationale: The most critical action for a severe latex allergy is to ensure the environment is
completely latex-free. Latex is found in many OR items like catheters, tourniquets, and
stopcocks, not just gloves. Powder-free latex gloves still contain latex protein and can cause
reactions. Medication administration is a nursing/anesthesia role, and while chart labels are
important, they do not physically remove the allergen from the room.
Q2: When verifying the patient's identity in the holding area, the surgical technologist must use
at least two unique identifiers. Which of the following pairs is the standard acceptable
combination?
A. The patient's room number and their date of birth.
B. The patient's name and their date of birth.
C. The patient's medical record number and their diagnosis.
D. The patient's name and their scheduled procedure time.
Correct Answer: B
,2
Rationale: The Joint Commission's "National Patient Safety Goals" require the use of two
identifiers—typically the patient's full name and date of birth or medical record number. Room
number and diagnosis are not unique identifiers and can lead to errors. Procedure time is not a
stable identifier for the patient themselves.
Q3: A patient is scheduled for a right total knee replacement. According to surgical safety
protocols, who is responsible for marking the surgical site?
A. The surgical technologist.
B. The circulating nurse.
C. The attending surgeon or the provider performing the procedure.
D. The anesthesiologist.
Correct Answer: C
Rationale: The attending surgeon or the performing provider is ultimately responsible for
marking the surgical site. This should be done with the patient awake and involved (if possible)
to verify the correct site. While nurses and technologists may witness the marking, the
responsibility lies with the surgeon.
Q4: The surgical consent form must be signed by the patient or legal guardian. When should this
consent be obtained?
A. Immediately after induction of anesthesia.
B. After the patient is transported to the operating room table.
C. Before the administration of any sedation or anesthesia.
D. In the post-anesthesia care unit (PACU).
Correct Answer: C
Rationale: Informed consent must be obtained while the patient is fully alert and capable of
understanding the risks, benefits, and alternatives. Obtaining consent after sedation invalidates
the consent because the patient's decision-making capacity is impaired.

Q5: Which of the following laboratory values is most critical to review preoperatively for a
patient scheduled for a cardiac bypass procedure?
A. Serum glucose
B. Type and Screen
C. Platelet count
D. Creatinine
Correct Answer: B
Rationale: Type and Screen is critical for any procedure with a high risk of blood loss, such as
cardiac bypass. It ensures that blood products are available and cross-matched if a transfusion
becomes necessary. While other labs are important, the immediate availability of compatible
blood is life-saving in cardiac surgery.
Q6: A patient taking warfarin (Coumadin) is scheduled for surgery. Which lab test evaluates the
therapeutic effect of this medication?
A. PT/INR (Prothrombin Time/International Normalized Ratio)
B. PTT (Partial Thromboplastin Time)
C. aPTT (Activated Partial Thromboplastin Time)
D. Bleeding Time
Correct Answer: A
Rationale: PT/INR is the standard test to monitor the anticoagulant effects of warfarin. It
measures the extrinsic pathway of coagulation. PTT/aPTT is typically used to monitor heparin
therapy.
Q7: What is the primary purpose of the "Time Out" immediately before incision?
A. To verify the sterility of the instruments.
B. To confirm the correct patient, procedure, site, and, if applicable, implant.
C. To allow the anesthesiologist to check the vital signs.
, 4
D. To give the surgeon a moment to wash hands.
Correct Answer: B
Rationale: The surgical "Time Out" is a mandated pause to actively communicate and confirm
critical safety details: patient identity, the scheduled procedure, the surgical site, and the
availability of necessary implants/equipment. It is a final verification to prevent wrong-site
surgery.
Q8: Which of the following positions is characterized by the patient lying on their back with the
hips flexed and the legs supported in stirrups?
A. Lithotomy
B. Trendelenburg
C. Kraske
D. Prone
Correct Answer: A
Rationale: The lithotomy position is used for gynecological, urological, and rectal procedures. It
involves the patient lying supine with the legs abducted and flexed, supported by stirrups.
Trendelenburg is supine with the head lowered.
Q9: When placing a patient in the Trendelenburg position, which anatomical landmark is most at
risk for pressure injury?
A. The sacrum
B. The heels
C. The occiput (back of the head)
D. The elbows
Correct Answer: C
Rationale: In the Trendelenburg position, the patient's head is lower than their feet. Gravity shifts
the patient's body weight toward the head, causing significant pressure on the occiput and
