Final answer:
For a patient with severe emphysema, Fowler's position is most suitable while waiting for a physician. This position aids in breathing by reducing diaphragm pressure and promoting lung expansion. Other listed positions may worsen respiratory issues in emphysema patients.
Step-by-step explanation:
The question pertains to the most suitable position for a patient with severe emphysema while waiting to be examined by a physician. Among the options provided, position D, Fowler's position, is the most appropriate for such patients. In the Fowler's position, the patient is seated in an upright position, usually at an angle between 45 and 60 degrees. This position facilitates breathing by reducing pressure on the diaphragm and allowing the lungs to expand more easily, offering significant respiratory relief for emphysema sufferers.
It is essential to understand that Trendelenburg, knee-chest, and supine positions can present challenges for patients with severe respiratory issues. The Trendelenburg position involves lying on the back with the body tilted so that the head is lower than the feet, which may increase breathing difficulty. The knee-chest position, pressing the chest against the knees while on all fours, also restricts lung expansion. The supine position, where the patient lies flat on their back, can hinder respiratory function in emphysema patients by increasing the pressure on the chest and diaphragm.
