Final answer:
After endotracheal intubation, patients should avoid deep-breathing and coughing exercises to prevent exacerbating throat discomfort and avoid potential complications.
Step-by-step explanation:
A CPCT (Certified Patient Care Technician) should recognize that patients must avoid deep-breathing and coughing exercises after endotracheal intubation surgery. This medical procedure is often necessary during surgeries that require general anesthesia to maintain an open airway while the patient's muscles necessary for breathing are not functioning properly. Post-surgery, it is typical for patients to experience a sore or scratchy throat for a few days due to the intubation tube that was in place.
Therefore, engaging in activities like deep-breathing and coughing exercises immediately after surgery could exacerbate throat discomfort and potentially cause other complications.
