ATI RN Adult Medical Surgical Online Practice 2023 A

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.

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: 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: D

Rationale: In acute respiratory distress syndrome (ARDS), placing the client in a prone position helps improve ventilation-perfusion matching and oxygenation. This position can optimize lung function and is a beneficial intervention for clients with ARDS. Administering low-flow oxygen via nasal cannula, encouraging oral intake of excess fluids, or offering high-protein and high-carbohydrate foods are not primary interventions for ARDS and may not directly address the respiratory distress experienced by the client.

Correct Answer: B

Rationale: Atelectasis is a condition where the alveoli in the lungs collapse, leading to impaired gas exchange. As a result, the client may experience increasing dyspnea (difficulty breathing) due to the decreased lung capacity for oxygen exchange. Facial flushing, decreasing respiratory rate, and friction rub are not typically associated with atelectasis.
