Preoperative Patient Preparation Flashcards

A 68-year-old male is scheduled for an elective total knee arthroplasty. He has a history of atrial fibrillation and has been on a direct oral anticoagulant (DOAC). According to current guidelines for a high-bleed-risk surgery, what is the most appropriate instruction regarding his anticoagulation medication?

Answer: Stop the DOAC 2 days before the procedure and skip it on the day of and the day after surgery.

For high-bleed-risk surgeries, such as a total knee arthroplasty, direct oral anticoagulants (DOACs) are typically stopped 2 days before the procedure. The medication is also held on the day of surgery and the day immediately following to minimize the risk of significant perioperative bleeding. Bridging therapy is not routinely recommended for DOACs due to their shorter half-life compared to warfarin.

Which of the following is the primary goal of the preoperative "Time Out" as mandated by The Joint Commission's Universal Protocol?

Answer: To conduct a final verification of the correct patient, procedure, and site involving the entire surgical team.

The Universal Protocol's "Time Out" is a critical safety check performed immediately before the incision. Its main purpose is to involve the entire surgical team (surgeon, anesthesia, nursing, and surgical assistant) in actively confirming the correct patient identity, the correct procedure, and the correct surgical site to prevent wrong-site, wrong-procedure, and wrong-person surgery.

Regarding preoperative hair removal at the surgical site, which method and timing are most consistent with evidence-based guidelines to reduce the risk of surgical site infections (SSIs)?

Answer: Using clippers immediately before the procedure, outside the operating room.

Guidelines from organizations like AORN recommend that hair should only be removed if it interferes with the procedure. When removal is necessary, using electric clippers is the preferred method as it minimizes skin trauma. This should be done as close to the time of surgery as possible, and preferably outside the sterile operating room to prevent loose hair from contaminating the field.

A patient is scheduled for an elective cholecystectomy at 2:00 PM. According to the American Society of Anesthesiologists (ASA) NPO guidelines, which of the following is permissible?

Answer: Water and other clear liquids up until 12:00 PM.

The ASA guidelines state that patients may ingest clear liquids up to 2 hours before procedures requiring general anesthesia. For a 2:00 PM surgery, clear liquids would be permissible until 12:00 PM. A light meal must be finished at least 6 hours prior, and fatty meals 8 hours prior. While some institutions still use the "NPO after midnight" rule for simplicity, it is not reflective of current evidence-based guidelines, especially for afternoon procedures.

During the preoperative verification process, the CSFA notes that the patient's signed surgical consent form lists "Right knee arthroscopy," but the surgeon's H&P and the OR schedule both state "Left knee arthroscopy." What is the most appropriate immediate action?

Answer: Bring the discrepancy to the immediate attention of the surgeon and the circulating nurse to be resolved before the patient enters the OR.

A discrepancy between the consent form, the patient's chart, and the OR schedule is a major red flag that must be resolved before the patient is taken to the operating room. The CSFA has a crucial role in patient safety and must halt the process and alert the surgeon and nursing staff. Proceeding without a clear and correct consent could lead to a wrong-site surgery, which is a sentinel event. The consent must be clarified and potentially re-signed by the patient while they are competent to do so.

Which of the following is NOT a required element for a valid informed surgical consent?

Answer: A detailed explanation of the surgeon's experience with the procedure.

While a surgeon's experience is important, it is not a legally required component of the informed consent document itself. The core elements of informed consent include the patient's diagnosis, the name and description of the procedure, the risks and benefits, and a discussion of alternatives, including the option of no treatment. The patient must also have the opportunity to ask questions.
