Correct Answer: C

Rationale:

Correct Answer: B

Rationale: Administering oxygen therapy is the priority intervention for a client with a pulmonary embolism. Oxygen helps improve oxygenation levels and decrease the workload on the heart. It is crucial to ensure adequate oxygenation before other interventions are initiated. Morphine IV, starting an IV infusion of lactated Ringer's, and initiating cardiac monitoring are important interventions but come after ensuring adequate oxygenation.

Correct Answer: B

Rationale: In a client with chronic bronchitis, the nurse or healthcare provider would expect to hear resonant sounds upon percussion. Resonance is the normal percussion sound heard over healthy lung tissue. The other options such as dullness, tympany, and flatness are associated with different conditions or abnormalities, not typically expected in chronic bronchitis.

Correct Answer: C

Rationale: It is essential to advise the client to avoid speaking for extended periods after the removal of the endotracheal tube to prevent strain on the vocal cords and allow the airway to recover. Speaking for prolonged periods can lead to irritation and potentially affect the healing process. The other options are also important post-extubation instructions, such as using the incentive spirometer to maintain lung function, positioning in a side-lying position for comfort, and frequent monitoring of vital signs to ensure the client's stability.

Correct Answer: A

Rationale: Stridor is a high-pitched, harsh respiratory sound that can indicate airway obstruction. It is a serious finding that requires immediate attention as it may lead to respiratory compromise. Copious oral secretions, hoarseness, and sore throat are common but expected findings after endotracheal tube removal and do not typically require urgent intervention.
