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: 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: Before initiating percussion, vibration, and postural drainage, the nurse should first auscultate the lung fields to assess the baseline lung sounds and identify areas of congestion or abnormality. This initial assessment helps the nurse to tailor the percussion and drainage techniques effectively. Assessing pulse and respirations, sputum characteristics, and providing instructions to the client for exhalation are important steps in the procedure but should follow the initial auscultation to ensure a comprehensive and individualized care approach.

Correct Answer: D

Rationale: When a client expresses being short of breath, it may indicate a serious condition requiring immediate attention to ensure adequate oxygenation. This client should be seen first to assess the severity of the situation and initiate appropriate interventions. The other options, such as awaiting transport for an x-ray, having a prescription for discharge, or receiving oral pain medication 30 minutes ago, do not present immediate life-threatening concerns compared to a client experiencing shortness of breath.

Correct Answer: B

Rationale: When suspecting anaphylaxis, the priority intervention is to assess the client's respiratory status by counting the respiratory rate. Respiratory distress is a hallmark sign of anaphylaxis, and prompt recognition and management are crucial. Administering oxygen may be necessary, but assessing the respiratory rate takes precedence to determine the severity of the reaction and the need for immediate intervention. Inserting an IV line and preparing for intubation are important interventions in managing anaphylaxis but are secondary to ensuring adequate ventilation.
