Correct Answer: B

Rationale: In acute respiratory failure, the body is not getting enough oxygen, leading to hypoxia. Symptoms of hypoxia include severe dyspnea (A), decreased level of consciousness (C), and headache (D) due to inadequate oxygen supply to the brain. Nausea (B) is not a typical manifestation of acute respiratory failure and is not directly related to the lack of oxygen in the body. Therefore, the nurse should not monitor the client for nausea as a direct consequence of ARF.

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: Following a bronchoscopy, the priority for the nurse is to confirm the gag reflex in the older adult client. This is crucial to ensure that the client's airway is protected and free from any obstruction or aspiration. Monitoring the gag reflex helps in preventing complications such as aspiration pneumonia. While auscultating breath sounds, observing for confusion, and measuring blood pressure are important assessments, confirming the gag reflex takes precedence in this situation to maintain airway patency and prevent potential respiratory complications.

Correct Answer: A

Rationale: In cardiogenic pulmonary edema, the priority intervention is to improve oxygenation and reduce the workload on the heart. Providing supplemental oxygen at 5 L/min via facemask helps increase oxygen levels and alleviate respiratory distress. This intervention can help improve oxygen saturation, alleviate dyspnea, and support the client's respiratory function. Placing the client in a high-Fowler's position with legs dependent can also help with respiratory effort, but ensuring adequate oxygenation takes precedence. Sublingual nitroglycerin and IV morphine sulfate are commonly used interventions for cardiac-related conditions, but in this case, addressing oxygenation is the priority to prevent further deterioration.
