CST Preoperative Preparation 1 — Questions and Answers
Question 1: What is the primary goal of preoperative skin preparation?
- Moisturizing the skin
- Enhancing skin elasticity
- Reducing microbial count near the incision site (Correct answer)
- Warming the skin for comfort
Correct answer: Reducing microbial count near the incision site
The primary goal of preoperative skin preparation, often called 'prepping,' is to significantly reduce the number of microorganisms on the patient's skin around the planned incision site. This critical aseptic technique minimizes the risk of surgical site infections (SSIs) by preventing bacteria from entering the surgical wound during the procedure, ensuring patient safety.
Question 2: Why is the patient NPO before surgery?
- To prevent dehydration
- To improve blood flow
- To avoid bloating
- To prevent aspiration during anesthesia (Correct answer)
Correct answer: To prevent aspiration during anesthesia
Patients are required to be NPO (Nil per os, meaning 'nothing by mouth') before surgery to prevent pulmonary aspiration. During anesthesia, the body's protective reflexes, such as the gag reflex, are suppressed. If there is food or liquid in the stomach, it can be regurgitated and then aspirated into the lungs, leading to severe respiratory complications like pneumonia.
Question 3: Which item must be verified before transporting a patient to the OR?
- Insurance provider
- Patient's favorite music
- Surgical site and patient identity (Correct answer)
- Number of visitors
Correct answer: Surgical site and patient identity
Verifying the surgical site and patient identity is a critical safety measure known as the 'time-out' or Universal Protocol. This step prevents wrong-site, wrong-procedure, or wrong-patient errors, ensuring the correct surgery is performed on the correct individual.
Question 4: What is the purpose of preoperative shaving?
- To improve the aesthetic of the incision
- To identify the incision site
- To prevent interference with dressings
- To reduce microbial presence near the site (Correct answer)
Correct answer: To reduce microbial presence near the site
The primary purpose of preoperative hair removal (often clipping rather than shaving) is to reduce the number of microorganisms on the patient's skin. This minimizes the risk of bacteria entering the surgical incision, thereby preventing surgical site infections and promoting better patient outcomes.
Question 5: Which antiseptic is commonly used in surgical skin prep?
- Alcohol wipes
- Hydrogen peroxide
- Povidone-iodine (Correct answer)
- Sterile water
Correct answer: Povidone-iodine
Povidone-iodine is a widely used antiseptic for surgical skin preparation due to its broad-spectrum antimicrobial activity. It effectively kills bacteria, viruses, and fungi on the skin, significantly reducing the microbial load and lowering the risk of surgical site infections.
Question 6: Why are jewelry and metal objects removed before surgery?
- To keep items safe
- To follow dress code
- To prevent surgical burns and infection (Correct answer)
- To ensure better anesthesia delivery
Correct answer: To prevent surgical burns and infection
Jewelry and metal objects must be removed before surgery to prevent surgical burns, especially when electrocautery is used, as metal can conduct electricity. Additionally, these items can harbor microorganisms, increasing the risk of infection, and could interfere with surgical procedures or get lost.
Question 7: What is the role of the surgical checklist?
- To document anesthesia doses
- To track hospital supplies
- To verify key surgical and patient details (Correct answer)
- To calculate surgery duration
Correct answer: To verify key surgical and patient details
The surgical checklist is a vital patient safety tool, often based on the WHO Surgical Safety Checklist. Its role is to systematically verify key details such as patient identity, surgical site marking, allergies, and equipment availability, ensuring all critical steps are completed before, during, and after surgery.
Question 8: What is the appropriate time for administering prophylactic antibiotics?
- Two hours after surgery
- One hour before incision (Correct answer)
- Immediately after discharge
- At the time of anesthesia induction
Correct answer: One hour before incision
Administering prophylactic antibiotics within one hour before the surgical incision ensures that a sufficient concentration of the antibiotic is present in the patient's tissues. This optimal timing maximizes the antibiotic's effectiveness in preventing surgical site infections by targeting bacteria at the time of potential exposure.
Question 9: What is the correct action if the surgical consent form is incomplete?
- Proceed with verbal consent
- Notify the circulating nurse immediately (Correct answer)
- Ask the anesthesiologist to sign
- Delay surgery until after rounds
Correct answer: Notify the circulating nurse immediately
An incomplete surgical consent form indicates that the patient has not provided full informed consent for the procedure. The circulating nurse is responsible for ensuring all documentation is accurate and complete, and must be notified immediately to address and rectify the issue before surgery can legally and ethically proceed.
