Which patient does the LPN/LVN identify at high risk for hospital-acquired pneumonia?

Correct Answer: C

Rationale: This patient is at high risk for hospital-acquired pneumonia. After a splenectomy (removal of the spleen), patients may experience pain and discomfort, which can make them reluctant to perform necessary activities like coughing and deep breathing. These activities are crucial for preventing lung complications such as atelectasis and pneumonia.

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: In a client with a traumatic brain injury, the primary indication for oxygen therapy is to ensure adequate oxygen supply to the brain and prevent further neurological damage.

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.
