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: 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: 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: When encountering a choking individual, the nurse should first assess the person's ability to speak. If the person can speak, it indicates that their airway is partially obstructed, allowing some air to pass. In this case, encouraging the person to continue coughing and monitoring them closely may be appropriate. If the person cannot speak, it may suggest a complete airway obstruction and immediate intervention is required. Instructing the person to call 911 (Choice A) may be necessary if the situation worsens. Using the jaw-thrust maneuver (Choice C) is not appropriate for a choking victim. Performing abdominal thrusts (Choice D) is typically recommended for conscious choking victims, not chest compressions.

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.
