A nurse is preparing a patient for an arthroscopy of the knee. Which patient statement indicates a need for further teaching?

Choice A rationale Swelling is a common and expected physiological response following a knee arthroscopy due to the irrigation fluid used during the procedure and the minor surgical trauma to the joint capsule. Patients are typically taught to use ice packs and elevation to manage this inflammation. This statement reflects a correct understanding of the normal postoperative course, and therefore, it does not indicate a need for further teaching or clarification from the nursing staff. Choice B rationale Knee arthroscopy is usually performed as an outpatient or same-day surgical procedure. Patients are typically discharged once they are stable, have managed their pain, and can void. Stating that an overnight stay is expected suggests the patient does not understand the typical recovery timeline or discharge plan. This requires the nurse to clarify that, barring complications, the patient will return home shortly after recovering from the effects of the anesthesia. Choice C rationale Remaining NPO, or nothing by mouth, for a specific period before surgery is a standard safety requirement to prevent pulmonary aspiration of gastric contents during anesthesia. This instruction is critical for patient safety during any procedure involving sedation or general anesthesia. Since the patient acknowledges the need to avoid eating or drinking, they have correctly understood the preoperative preparation instructions, and no further teaching is required on this specific safety point. Choice D rationale An arthroscopy involves the insertion of an endoscope into the joint, which allows the surgeon to see the internal structures clearly on a monitor. This provides a direct view of the cartilage, ligaments, and meniscus for diagnosis or repair. The patient's statement correctly identifies the primary mechanism and benefit of the procedure. Because this reflects an accurate understanding of the surgical process, it does not necessitate any additional education or correction.
