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: B

Rationale: The correct answer is Fluticasone. Carvedilol, Captopril, and Isosorbide dinitrate are commonly used in heart failure management and do not typically pose significant risks for clients with a history of asthma. However, Fluticasone is a corticosteroid used to manage asthma but can potentially worsen heart failure symptoms due to its anti-inflammatory effects. Therefore, the nurse should seek clarification regarding the prescription of Fluticasone for a client with heart failure and a history of asthma.

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: 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.
