ATI RN Adult Medical Surgical Online Practice 2023 A

Correct Answer: A

Rationale: In this situation, the priority action is to provide high-flow oxygen to the client. Sudden onset dyspnea and severe chest pain can be indicative of a pulmonary embolism, which is a life-threatening emergency. Oxygen therapy helps improve oxygenation and stabilizes the client's condition. Checking for Chvostek's sign, administering IV vasopressors, or monitoring for a headache are not the immediate priorities in this critical situation.

Correct Answer: B

Rationale: In a client with a high respiratory rate, low PaO2, and low SaO2, the priority intervention is to improve oxygenation. Administering oxygen via a face mask will help increase the oxygen supply to the client's lungs and tissues, addressing the hypoxemia. While mechanical ventilation may be necessary in severe cases, administering oxygen is the initial and most appropriate intervention to address the client's respiratory distress. Sedatives should not be given without ensuring adequate oxygenation. Assessing for pulmonary embolism is important but not the priority at this moment when the client is experiencing respiratory distress and hypoxemia.

Correct Answer: A

Rationale: In a client with multiple system trauma, airway protection is the priority focus of care. Ensuring a patent airway is crucial for oxygenation and ventilation, which are essential for maintaining vital functions. Without a clear airway, the client's oxygenation and ventilation could be compromised, leading to severe consequences. While decreasing intracranial pressure, stabilizing cardiac arrhythmias, and preventing musculoskeletal disability are important aspects of care, ensuring airway protection takes precedence in this emergency situation.

Correct Answer: C

Rationale: During an asthma attack, hypoxemia can lead to inadequate oxygen supply to the brain, causing symptoms like restlessness, confusion, and agitation. These manifestations result from the body's response to low oxygen levels, aiming to increase oxygenation. Nausea, dysphagia, and hypotension are not typical manifestations of hypoxemia during an asthma attack.

Correct Answer: B

Rationale: The absence of fluctuations in the water seal chamber indicates that the client's lung has re-expanded. This finding suggests that the negative pressure in the pleural space is restored, preventing air from entering the system. Oxygen saturation, absence of pleuritic chest pain, and occasional bubbling in the water-seal chamber are important assessments but do not specifically indicate lung re-expansion.
