Certified Surgical Technologist Preoperative Care and Preparation Questions and Answers — Questions and Answers
Question 1: A 6-year-old patient is scheduled for a tonsillectomy. According to standard NPO guidelines, what is the minimum fasting period required for solid foods before surgery?
- 2 hours
- 4 hours
- 6 hours
- 8 hours (Correct answer)
Correct answer: 8 hours
For children 6 months of age or older, the general NPO guideline for solid food is a minimum of 8 hours before surgery to reduce the risk of pulmonary aspiration during anesthesia. Breast milk is typically 4-6 hours, and clear liquids are often allowed up to 2-3 hours before the procedure.
Question 2: Which of the following is the PRIMARY responsibility of the surgical technologist regarding the surgical consent form?
- Explaining the risks and benefits of the procedure to the patient.
- Obtaining the patient's signature on the form.
- Verifying that the signed consent form is in the patient's chart before the procedure begins. (Correct answer)
- Determining if the patient is mentally competent to sign the consent.
Correct answer: Verifying that the signed consent form is in the patient's chart before the procedure begins.
While the surgeon is responsible for explaining the procedure and obtaining consent, the surgical technologist, as part of the entire surgical team, must verify that a valid and signed consent form is present in the patient's medical record before the surgery starts. This is a critical step in the preoperative verification process.
Question 3: A patient is scheduled for a left knee arthroscopy. According to the Universal Protocol, which action is most critical for preventing wrong-site surgery?
- Verifying the patient's name and date of birth.
- Reviewing the patient's imaging studies in the operating room.
- Marking the operative site with an indelible marker before the patient is sedated. (Correct answer)
- Confirming the procedure with the circulating nurse.
Correct answer: Marking the operative site with an indelible marker before the patient is sedated.
The Universal Protocol for Preventing Wrong Site, Wrong Procedure, and Wrong Person Surgery requires marking the operative site. This mark should be made by the person performing the procedure, involve the patient while they are awake and aware, and be visible after prepping and draping. While all other steps are important parts of the verification process, the physical marking of the site is a key preventative measure.
Question 4: When preparing a patient's skin for surgery, which of the following is the primary goal of the preoperative skin prep?
- To sterilize the patient's skin.
- To remove all resident and transient flora.
- To reduce the number of microorganisms on the skin to an irreducible minimum. (Correct answer)
- To remove hair from the surgical site.
Correct answer: To reduce the number of microorganisms on the skin to an irreducible minimum.
The primary goal of preoperative skin antisepsis is to remove soil and transient microorganisms and to reduce the resident microbial count to the lowest possible level, thereby reducing the risk of a surgical site infection (SSI). It is not possible to completely sterilize the skin, as some resident flora will always remain.
Question 5: A patient arrives in the preoperative holding area for a hernia repair. The surgical technologist's review of the patient's chart is an essential part of the preparation. Which of the following findings should be immediately reported to the surgeon and anesthesia provider?
- The patient has a documented allergy to latex.
- The patient's history and physical was completed yesterday.
- The patient reports taking their prescribed blood pressure medication with a sip of water this morning.
- The patient states they had a bowl of cereal two hours ago. (Correct answer)
Correct answer: The patient states they had a bowl of cereal two hours ago.
Violating NPO (nothing by mouth) guidelines significantly increases the risk of pulmonary aspiration during anesthesia. Having solid food two hours before surgery is a major safety concern that must be communicated immediately, as it may lead to the delay or cancellation of the procedure. A latex allergy is important but managed with latex-free supplies. Taking essential medication with a sip of water is often permitted. A recent H&P is standard.
Question 6: During preoperative patient identification, which of the following methods is considered the most reliable practice according to WHO guidelines?
- Asking the patient, "Are you John Smith?"
- Checking the patient's room number against the surgical schedule.
- Using at least two patient identifiers, such as name and date of birth. (Correct answer)
- Matching the patient's appearance to their chart photograph.
Correct answer: Using at least two patient identifiers, such as name and date of birth.
The World Health Organization (WHO) and other patient safety organizations recommend using at least two patient identifiers to verify a patient's identity before any procedure. This should involve asking the patient to state their full name and date of birth. Using the room number is unreliable, and asking a yes/no question is not as safe as having the patient state the information themselves.
