The nurse assists the patient with emphysema into the most beneficial position to facilitate respiration, which is:

sitting upright and forward with arms supported on an over the bed table

semi-Fowler's position with a single pillow behind the head

high Fowler's position without a pillow behind the head

right lateral with the head of the bed elevated 45 degrees.

Answer and Explanation

The Correct Answer is A

A. Sitting upright and forward with arms supported on an over-the-bed table: This tripod position allows for maximum lung expansion by reducing pressure on the diaphragm and improving airflow, especially for patients with chronic obstructive pulmonary disease (COPD).
B. Semi-Fowler's position with a single pillow behind the head: This position does not optimize lung expansion as well as the tripod position.
C. High Fowler's position without a pillow behind the head: Although better than lying flat, this position lacks arm support, which helps in leveraging accessory muscles for breathing.
D. Right lateral with the head of the bed elevated 45 degrees: This position is not beneficial for promoting effective lung expansion in patients with emphysema.

Correct Answer is B

Explanation

A. More than 250 mL of air moves in and out of the lungs with each breath: This describes tidal volume but does not directly stimulate the cough mechanism.
B. Foreign substances are propelled by the cilia toward the respiratory tract: Irritation by foreign particles stimulates the cough reflex to clear the airways.
C. Dehumidified air enters the upper airway passages: Dry air can cause airway irritation but does not consistently trigger a cough reflex.
D. The blood transports carbon dioxide to the lungs: This describes gas exchange, which does not directly relate to triggering the cough mechanism.

A. endotracheal tube B. partial rebreather oxygen mask C. tracheostomy D. pharyngeal airway

Correct Answer is D

Explanation

A) Endotracheal tube. An endotracheal tube is invasive and used for patients who require mechanical ventilation, not for simple airway maintenance.
B) Partial rebreather oxygen mask. A partial rebreather mask is used to deliver oxygen, not to maintain airway patency.
C) Tracheostomy. A tracheostomy is a surgical procedure for long-term airway management and is unnecessary in this scenario.
D) Pharyngeal airway. A pharyngeal airway helps maintain airway patency by preventing the tongue from obstructing the airway.
