A nurse is providing education to a client about the risk factors for deep vein thrombosis (DVT). Which statement made by the client indicates a need for further teaching?

A) This choice is incorrect because age and family history are non-modifiable risk factors for DVT. While they may increase the risk, they cannot be changed or controlled by the client.

B) This choice is incorrect because stopping prescribed anticoagulant medication is not recommended and may increase the risk of DVT. Anticoagulants are often prescribed to prevent or treat DVT and should not be discontinued without healthcare provider guidance.

C) This choice is correct. Smoking is a modifiable risk factor for DVT, and quitting smoking can reduce the risk of blood clot formation and other cardiovascular complications.

D) This choice is incorrect because while the client may have difficulty controlling a sedentary lifestyle, it is still considered a modifiable risk factor for DVT. Engaging in regular physical activity can help reduce the risk of blood clot formation.

A) This choice is incorrect because arterial blood gas (ABG) analysis assesses oxygen and carbon dioxide levels in the blood, primarily used for respiratory and acid-base evaluations, not for confirming DVT.

B) This choice is correct. The D-dimer blood test is a screening test used to detect the presence of blood clot breakdown products in the blood. Elevated levels of D-dimer may suggest the presence of a blood clot, prompting further diagnostic testing for DVT.

C) This choice is incorrect because an electrocardiogram (ECG) primarily assesses the electrical activity of the heart and is not specific to confirming DVT. It may be useful to assess cardiac function in individuals with suspected pulmonary embolism.

D) This choice is incorrect because a chest X-ray is not used to confirm DVT. It is helpful in assessing the lungs and heart, particularly for detecting potential complications of DVT like a pulmonary embolism, but it does not directly diagnose DVT.
