A client with chronic obstructive pulmonary disease (COPD) is prescribed long-term oxygen therapy. What is the most important nursing consideration for this client?

Correct Answer: B

Rationale: 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.

Correct Answer: D

Rationale: Administering humidified oxygen through the cannula helps prevent nasal dryness and ensures comfortable and effective oxygen delivery. (Note: This question lacks a direct answer in the document; rationale is generated based on context from Question 22 and general practice.)

Correct Answer: A

Rationale: Prolonged use of a nasal cannula can lead to dryness and discomfort in the nasal passages due to the direct flow of oxygen. The nurse should provide humidification to prevent or alleviate dryness and nasal irritation.

Correct Answer: B

Rationale: Condensation in the oxygen tubing can impede the flow of oxygen and reduce the effectiveness of oxygen therapy. The nurse should disconnect the tubing and drain the condensation before reconnecting and continuing oxygen therapy.

Correct Answer: C

Rationale: The client reporting nasal dryness and discomfort indicates inadequate humidification of the oxygen. The nurse should assess and adjust the oxygen flow rate or consider providing additional humidification to alleviate the client's discomfort and ensure effective oxygen therapy.
