A client is receiving oxygen therapy via a nasal cannula. What is the appropriate flow rate for this client?

Answer: b. 4-6 liters per minute

Explanation: The appropriate flow rate for oxygen therapy via a nasal cannula typically ranges from 1-6 liters per minute, with 4-6 liters per minute being a common range to achieve adequate oxygenation.

Incorrect choices:

a. 1-2 liters per minute may be appropriate for clients with mild hypoxemia or during rest.

c. 8-10 liters per minute is generally too high for a nasal cannula and may not be well-tolerated by the client.

d. 12-15 liters per minute is excessively high for a nasal cannula and may be more suitable for a higher flow oxygen delivery system such as a non-rebreather mask or Venturi mask.

Answer: b. Monitoring the client's carbon dioxide levels

Explanation: Clients with COPD have a chronic retention of carbon dioxide, so monitoring carbon dioxide levels is essential to prevent the development of respiratory acidosis while providing long-term oxygen therapy.

Incorrect choices:

a. Assessing for signs of oxygen toxicity is important but is not specific to clients with COPD.

c. Proper humidification of oxygen is beneficial but does not take precedence over monitoring carbon dioxide levels in clients with COPD.

d.Ensuring an adequate supply of oxygen is a general consideration for all clients receiving oxygen therapy and is not specific to clients with COPD.
