Correct Answer: A

Rationale: The client's shallow respirations at 9/min indicate hypoventilation, leading to an accumulation of carbon dioxide in the blood, causing respiratory acidosis. In this scenario, the client is at risk for developing respiratory acidosis due to inadequate ventilation and subsequent CO2 retention.

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.

Correct Answer: B

Rationale: When a client develops an airway obstruction and remains conscious, the nurse's initial action should be to administer the abdominal thrust maneuver. This technique, also known as the Heimlich maneuver, can help dislodge the obstructing object and clear the airway. Inserting an oral airway, turning the client to the side, or performing a blind finger sweep are not recommended as the first interventions for a conscious individual with an airway obstruction.

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.
