Which activity should be restricted for a client following a transphenoidal hypophysectomy surgery?

A. Heavy lifting. Activities that increase intrathoracic or intra-abdominal pressure can cause a spike in intracranial pressure, risking a cerebrospinal fluid leak at the surgical site. Straining can compromise the integrity of the nasal packing or the graft used to close the sella turcica. Clients must avoid lifting objects over 5 to 10 pounds for several weeks postoperatively to ensure proper healing. B. Climbing stairs. Stair climbing is generally permitted as long as the client avoids overexertion and maintains a steady pace. It does not typically cause the significant increase in pressure associated with the Valsalva maneuver or heavy lifting. Patients are encouraged to ambulate slowly to prevent postoperative complications like deep vein thrombosis while remaining cautious of their balance. C. Breathing exercises. Deep breathing and use of an incentive spirometer are encouraged to prevent atelectasis and pneumonia after surgery. However, the client is strictly taught to avoid coughing, sneezing, or blowing their nose, as these actions create high pressure in the nasal cavity. If a sneeze is unavoidable, the client should keep their mouth open to dissipate the pressure. D. Sexual intercourse. While high-intensity physical exertion should be avoided, sexual activity is not specifically restricted unless it involves positions or straining that increase intracranial pressure. The primary focus of postoperative education is the avoidance of activities that directly stress the surgical site in the nasopharynx. Standard discharge instructions prioritize the prevention of straining over a total restriction of sexual activity.
