Final answer:
The physician will most likely plan for the insertion of a tracheostomy tube for a patient on mechanical ventilation for 2 weeks, as this method is safer for long-term ventilation.
Step-by-step explanation:
A patient in the ICU who has been orally intubated and on mechanical ventilation for 2 weeks after having a severe stroke can anticipate that the physician will most likely perform a procedure to insert a tracheostomy tube (C.). The extended period of intubation increases the risk of complications such as infection, and necessitates a more permanent and secure airway access. A tracheostomy tube is typically considered when long-term ventilation is expected, providing a direct airway through an incision in the neck directly into the trachea, enhancing patient comfort, and facilitating weaning from the ventilator.
