Correct Answer: A

Rationale: Respiratory acidosis is a condition characterized by increased carbon dioxide levels in the blood, resulting in acidosis. One of the potential consequences of respiratory acidosis is the development of electrolyte imbalances, particularly hyperkalemia. Hyperkalemia can lead to cardiac conduction abnormalities, manifested as widened QRS complexes on an electrocardiogram (ECG). Therefore, in a client with respiratory acidosis, the healthcare professional should expect to find widened QRS complexes as a result of the associated hyperkalemia.

Correct Answer: D

Rationale: In COPD, pursed-lip breathing helps improve breathing efficiency by maintaining positive pressure in the airways, preventing airway collapse, and promoting oxygenation. This technique assists in controlling respiratory rate, reducing dyspnea, and enhancing oxygen saturation levels. Restricting fluid intake is not typically a part of COPD management. Providing a low-protein diet is not a standard intervention for COPD. Early-morning hours are generally not recommended for exercise due to cooler temperatures and higher pollution levels, which can exacerbate COPD symptoms.

Correct Answer: D

Rationale:

Correct Answer: A

Rationale: When auscultating the lungs of a client with pleurisy, the healthcare professional should expect to hear loud, scratchy sounds. These sounds are characteristic of pleurisy, which is an inflammation of the pleura, causing a rough, grating sound during breathing.

Correct Answer: B

Rationale: When a client has burns involving the face, ears, and eyelids, the priority finding to report to the provider is difficulty swallowing. This symptom could indicate potential airway compromise or swelling in the throat, which can lead to serious complications. Monitoring and addressing this issue promptly is crucial to ensure the client's airway remains patent and secure.
