A nurse is assessing a client with suspected deep vein thrombosis (DVT). Which diagnostic test should the nurse anticipate to confirm the presence of DVT?

Arterial blood gas (ABG) analysis.

D-dimer blood test.

Electrocardiogram (ECG).

Chest X-ray.

Answer and Explanation

The Correct Answer is B

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.

Correct Answer is A

Explanation

A) This choice is correct. Gender is a non-modifiable risk factor for DVT, with women generally having a higher risk than men. Hormonal changes, such as those associated with pregnancy, oral contraceptives, and hormone replacement therapy, can contribute to the increased risk in women.

B) This choice is incorrect because obesity is a modifiable risk factor for DVT, not a non-modifiable one. Clients can work to achieve and maintain a healthy weight to reduce their risk.

C) This choice is incorrect because smoking history is a modifiable risk factor for DVT. Clients can quit smoking to decrease their risk of blood clot formation.

D) This choice is incorrect because a sedentary lifestyle is a modifiable risk factor for DVT. Clients can engage in regular physical activity to reduce their risk.

A. "DVT is caused by a bacterial infection in the blood vessels." B. "The exact cause of DVT is unknown, but it can be triggered by injuries." C. "DVT is primarily caused by atherosclerosis in the arteries." D. "The formation of blood clots in the veins is the main cause of DVT."

Correct Answer is D

Explanation

A) This choice is incorrect because DVT is not caused by a bacterial infection in the blood vessels. It is primarily related to the formation of blood clots within the veins due to various risk factors.

B) This choice is incorrect because while injuries may be associated with DVT in some cases, they are not the primary cause. The formation of blood clots in the veins remains the underlying cause.

C) This choice is incorrect because atherosclerosis in the arteries is not the main cause of DVT. Atherosclerosis is a condition that involves the buildup of plaque in the arteries, not the veins.

D) This choice is correct. Deep vein thrombosis (DVT) is primarily caused by the formation of blood clots within the veins, typically in the lower extremities. These clots can obstruct blood flow and may lead to serious complications if not treated promptly.
