Final answer:
The collaborative accountabilities of the perioperative team include placing cast padding under a tourniquet cuff and having an elastic wrap (Esmarch) available for exsanguination, which corresponds to answer d) both A and B.
Step-by-step explanation:
The collaborative accountabilities of the perioperative team include various safety and preparatory measures to ensure patient well-being during surgery. Among these responsibilities are: cast padding placed under a tourniquet cuff to protect the patient's skin, and ensuring that an elastic wrap (Esmarch) is available for exsanguination. The correct answer to the student's question, which involves selecting the measures included as collaborative accountabilities, is d) both A and B, indicating that both cast padding and elastic wrap should be considered in preparation for surgery. It is essential for the perioperative team to confirm each team member's role, the patient's identity, surgical site, and procedure; review critical steps and concerns; and ensure all necessary measures, such as prophylactic antibiotics and availability of essential equipment, are in place before the surgery begins.
