Correct Answer: B

Rationale: COPD and emphysema are chronic respiratory conditions that can lead to changes in the shape of the chest. In clients with COPD, the anteroposterior diameter of the chest often increases, giving a barrel chest appearance. This change in chest shape is due to hyperinflation of the lungs and is a common physical finding in clients with COPD and emphysema. The other options are not typically associated with COPD and emphysema. Respiratory alkalosis is not a common finding in these clients. An oxygen saturation level of 96% is within the normal range and does not specifically relate to COPD. Petechiae on the chest are not typically associated with COPD or emphysema.

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.

Correct Answer: B

Rationale: In a client with chronic bronchitis, the nurse or healthcare provider would expect to hear resonant sounds upon percussion. Resonance is the normal percussion sound heard over healthy lung tissue. The other options such as dullness, tympany, and flatness are associated with different conditions or abnormalities, not typically expected in chronic bronchitis.

Correct Answer: B

Rationale: Flail chest is characterized by paradoxical chest movement, where the chest moves inward during inspiration and bulges out during expiration. This occurs due to multiple rib fractures causing a segment of the chest wall to move independently from the rest of the thorax. Atelectasis refers to collapsed lung tissue, hemothorax is blood in the pleural space, and pneumothorax is air in the pleural space. In this scenario, the client's presentation aligns with the characteristic findings of flail chest.

Correct Answer: C

Rationale: It is essential to advise the client to avoid speaking for extended periods after the removal of the endotracheal tube to prevent strain on the vocal cords and allow the airway to recover. Speaking for prolonged periods can lead to irritation and potentially affect the healing process. The other options are also important post-extubation instructions, such as using the incentive spirometer to maintain lung function, positioning in a side-lying position for comfort, and frequent monitoring of vital signs to ensure the client's stability.
