Correct Answer: B

Rationale:

Correct Answer: A

Rationale: In a client with multiple injuries following a motor vehicle crash, the priority is to assess for any compromised airway or breathing. Evaluating chest expansion helps the nurse determine if the client is having any difficulty breathing, which is essential for immediate intervention to maintain adequate oxygenation. Checking pupillary response, assessing capillary refill, and checking the client's orientation to place and time are important assessments but are of lower priority compared to ensuring the client's airway and breathing are intact.

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: 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: A

Rationale: After a flexible bronchoscopy, it is crucial to withhold food and liquids until the client's gag reflex returns to prevent aspiration. Irrigating the client's throat every 4 hours, having the client refrain from talking for 24 hours, and frequent suctioning of the oropharynx are not indicated post-bronchoscopy and may even pose risks to the client's recovery.
