Final answer:
The correct action for the nurse to take in preoperative teaching for a client scheduled for an open cholecystectomy is to demonstrate ways to deep breathe and cough, which helps in preventing postoperative complications.
Step-by-step explanation:
The question involves the nursing care of a client who is scheduled for an open cholecystectomy, a surgical procedure to remove the gallbladder. Among the options provided, the correct action for the nurse to take is to demonstrate ways to deep breathe and cough. This is essential post-operative care intended to help prevent complications such as atelectasis and pneumonia by promoting lung expansion and clearance of secretions. While a clear liquid diet may be indicated immediately after surgery, it is not the primary teaching focus before discharge. Removing the incisional adhesive strips will be guided by the surgeon's postoperative care instructions, and it is often longer than 3 days. Instructing the client to maintain bed rest for 48 hours post-discharge is not standard postoperative advice, as early ambulation is encouraged to promote circulation and prevent clots.
