A client with a history of pulmonary embolism asks the nurse about ways to prevent future episodes. What should the nurse include in the response?

A) Incorrect. Jaundice is a yellowing of the skin and sclera due to elevated bilirubin levels, which is not described in the client's symptoms.

B) Incorrect. Pallor refers to paleness of the skin, which is not consistent with the client's cyanosis.

C) Incorrect. Erythema refers to redness of the skin due to increased blood flow, which is not the best description of the client's symptoms.

D) Correct. Cyanosis is the bluish discoloration of the skin, lips, and nail beds due to decreased oxygen saturation in the blood, which is indicative of a severe oxygen deficit often seen in pulmonary embolism.

A) Incorrect. Mild shortness of breath during activities may not be unusual, but sudden or severe shortness of breath should be reported.

B) Correct. Chest pain that worsens with deep breathing or coughing may indicate a worsening of the pulmonary embolism and should be reported immediately.

C) Incorrect. Mild swelling in the ankles is not typically a sign of a pulmonary embolism. However, severe leg swelling or pain should be evaluated.

D) Incorrect. An occasional cough with clear sputum is not necessarily a sign of a pulmonary embolism. However, if the cough becomes severe or is associated with other symptoms, it should be reported.
