A client with a history of pulmonary embolism reports experiencing sudden shortness of breath, lightheadedness, and rapid heart rate. Which term best describes this clinical presentation?

A) Incorrect. Wheezing is a high-pitched whistling sound that occurs during expiration and is not associated with crackling sounds.

B) Incorrect. Rhonchi are continuous low-pitched sounds heard during both inspiration and expiration, usually due to airway obstruction.

C) Incorrect. Stridor is a high-pitched, crowing sound that occurs during inspiration and suggests upper airway obstruction.

D) Correct. Rales, also known as crackles, are crackling or popping sounds heard during inspiration and can be indicative of fluid or inflammation in the lungs, which can occur with pulmonary embolism.

A) Incorrect. While pain management is important, providing supplemental oxygen to address severe shortness of breath takes priority.

B) Incorrect. Initiating anticoagulant therapy is essential but may take some time to have an effect. Oxygen therapy should be provided immediately to address the client's oxygenation.

C) Correct. Providing supplemental oxygen is the priority intervention for a client with severe

shortness of breath to ensure adequate oxygenation.

D) Incorrect. Encouraging ambulation is not appropriate in a client with severe shortness of breath. Stabilizing the client's oxygenation and condition is the immediate concern.
