Final answer:
Option b, repeating the procedure information calmly to the patient, is the most suitable nursing intervention for a patient who cannot understand preoperative information due to moderate anxiety.
Step-by-step explanation:
The most appropriate nursing intervention for a patient who is experiencing moderate anxiety and is unable to understand preoperative information is option b: In a calm voice, state I understand you are nervous. I will describe the procedure again. This acknowledges the patient's feelings, provides reassurance, and offers to go over the information again, ensuring that the patient has another opportunity to understand the preoperative details. It's important for health professionals to ensure the patient's comprehension, as this contributes to informed consent and can help alleviate anxiety.
Prior to the surgery, the medical team, which includes the surgeon, nurse, and anesthesia professional, performs a time out to verbally confirm critical aspects of the surgery such as patient identity, surgical site, and procedure. The surgeon discusses expected critical steps of the surgery, while the anesthesia staff reviews concerns specific to the patient. The nursing staff confirms sterility and equipment availability. At this stage, ensuring the patient understands the procedure is essential for their consent and safety.
