Correct Answer: D

Rationale: After a line is placed for hemodynamic monitoring, it is crucial to confirm its correct placement. The definitive way to verify the placement is through a chest x-ray. This ensures that the line is appropriately positioned without complications. Options A, B, and C do not address the essential step of confirming the line's placement, making them incorrect choices.

Correct Answer: B

Rationale: Vecuronium is a neuromuscular blocking agent that is used to facilitate ventilation by inducing muscle paralysis, which can help improve oxygenation in patients with ARDS. It does not treat infection, decrease inflammation, or reduce anxiety. Understanding the purpose of vecuronium administration is crucial for providing safe and effective care to patients with respiratory distress.

Correct Answer: C

Rationale: In this scenario, the client is presenting with signs of respiratory distress, including absent breath sounds, dyspnea, and a low SaO2 level. The priority action should be to improve oxygenation by administering oxygen via a high-flow mask. This intervention aims to increase the oxygen supply to the client's lungs, helping to address the hypoxemia. Once oxygenation is optimized, further interventions, such as obtaining a chest X-ray, preparing for chest tube insertion, or initiating IV access, can be considered based on the client's condition and healthcare provider's orders.

Correct Answer: C

Rationale: Albuterol is a bronchodilator commonly used to treat conditions like COPD. One of its common side effects is an increase in heart rate (tachycardia) due to its action on beta-2 receptors in the body. This statement by the client demonstrates an understanding of a potential side effect of albuterol, indicating comprehension of the discharge teaching provided by the healthcare provider.

Correct Answer: C

Rationale: Acute respiratory distress syndrome (ARDS) is a severe lung condition that can be triggered by various factors such as near-drowning incidents, surgeries like coronary artery bypass graft, and underlying conditions like dysphagia. Hemoglobin levels do not directly influence the risk of developing ARDS. A hemoglobin level of 15.1 g/dL falls within the normal range and does not predispose an individual to ARDS.
