Pulmonary disease (COPD), which nursing action best promotes adequate gas exchange?
a- Encouraging the client to drink three glasses of fluid daily
b- Keeping the client in semi-Fowler’s position
c- Using a high-flow Venturi mask to deliver oxygen as prescribed
d- Administering a sedative as prescribed.
Answer C.
The client with COPD retains carbon dioxide, which inhibits stimulation of breathing by the medullary center in the brain. As a result, low oxygen levels in the blood stimulate respiration, and administering unspecified, unmonitored amounts of oxygen may depress ventilation. To promote adequate gas exchange, the nurse should use a Venturi mask to deliver a specified, controlled amount of oxygen consistently and accurately. Drinking three glasses of fluid daily wouldn’t affect gas exchange or be sufficient to liquefy secretions, which are common in COPD. Clients with COPD and respiratory distress should be placed in high Fowler’s position and shouldn’t receive sedatives or other drugs that may further depress the respiratory center.
