Medical Surgical ATI Proctored Exam

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: A

Rationale: When assessing a client with pulmonary tuberculosis, the nurse should expect lethargy as a common finding. Tuberculosis can cause fatigue and weakness due to the body's efforts to fight the infection. High-grade fever is another common symptom of tuberculosis, not weight gain or dry cough. Weight loss is more typical in tuberculosis due to decreased appetite and systemic effects of the infection. A persistent productive cough with sputum is more characteristic of tuberculosis rather than a dry cough.

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.

Correct Answer: D

Rationale: A pulmonary artery catheter is primarily used to monitor hemodynamic status. It provides essential information on cardiac output, preload, afterload, and overall cardiovascular function. This data helps healthcare providers manage the client's fluid status, cardiac function, and guide treatment interventions in critically ill patients. Monitoring intracranial pressure, spinal cord perfusion, or renal function would require different monitoring devices and techniques, not a pulmonary artery catheter.

Correct Answer: B

Rationale: Administering oxygen therapy is the priority intervention for a client with a pulmonary embolism. Oxygen helps improve oxygenation levels and decrease the workload on the heart. It is crucial to ensure adequate oxygenation before other interventions are initiated. Morphine IV, starting an IV infusion of lactated Ringer's, and initiating cardiac monitoring are important interventions but come after ensuring adequate oxygenation.
