What is the role of a nurse during flexible endoscopy?

The correct choice highlights the essential responsibilities of a nurse during a flexible endoscopy procedure. Nurses play a critical role in patient care and safety throughout the endoscopic process. They assist the physician by preparing the patient, ensuring the environment is sterile, and managing any necessary equipment. Monitoring patient vitals during the procedure is also a vital function, as it helps detect any immediate changes in the patient’s condition that may require immediate attention.

After the procedure, the nurse is responsible for providing post-procedure care, which may include observing the patient for any complications, administering medications as prescribed, and educating the patient about aftercare instructions. This comprehensive involvement is crucial for ensuring the overall safety and well-being of the patient undergoing endoscopy.

The other options do not reflect the collaborative and supportive role that nurses have in this context. Administering anesthesia independently is typically outside the scope of practice for nurses unless they are specifically trained and certified anesthetists. Performing endoscopic procedures without supervision is exclusively the physician's role, and while documenting patient history is important, it represents only a part of the nurse's broader responsibilities during the entire endoscopy process.
