A nurse is caring for a client with suspected pulmonary embolism who is undergoing diagnostic testing. What diagnostic test is often used as an initial screening tool for pulmonary embolism?

A) Incorrect. Prolonged sitting during travel, especially on long flights, can increase the risk of pulmonary embolism due to immobility.

B) Incorrect. Long-term anticoagulant therapy is often prescribed to reduce the risk of pulmonary embolism, not increase it.

C) Correct. Prolonged immobility, such as sitting for long hours or bed rest, is a significant risk factor for pulmonary embolism.

D) Incorrect. Recent surgery, trauma, or hospitalization can increase the risk of developing pulmonary embolism due to factors such as immobility and altered blood clotting.

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.
