A patient has been diagnosed with a thrombus in the popliteal vein. When asked what causes deep vein thrombosis (DVT), the nurse would include which factors in a response?

Increased hydrostatic pressure causing twisted and distorted surface veins

Venous congestion and edema

Venous stasis, hypercoagulability, and injury to the blood vessel wall

Plaque rupture, thrombus formation, and infarction

Answer and Explanation

The Correct Answer is C

A. Increased hydrostatic pressure and twisted surface veins are characteristic of varicose veins, not DVT.

B. Venous congestion and edema may be symptoms of DVT but are not primary causes.

C. DVT commonly results from Virchow's triad: venous stasis, hypercoagulability, and injury to the vessel wall, which create an environment for clot formation in deep veins.

D. Plaque rupture, thrombus formation, and infarction are more relevant to arterial conditions, like atherosclerosis, rather than DVT.

Correct Answer is B

Explanation

A. Accessory muscle use is a response to respiratory distress, not the underlying cause of asthma symptoms.

B. Asthma causes inflammation and swelling of the bronchial lining, which narrows the airways and makes it difficult to exhale air from the lungs, leading to prolonged expiration and wheezing.

C. Destruction of elastic recoil is associated with chronic lung conditions like emphysema, not asthma.

D. Stiff alveoli and fluid-filled lungs are more characteristic of restrictive lung diseases or pulmonary edema, not asthma.

A. low preload. B. pleural effusion. C. peripheral edema. D. pulmonary edema.

Correct Answer is D

Explanation

A. Preload is typically increased in LHF, as blood backs up in the left side of the heart.

B. Although pleural effusion can occur as a secondary complication in some cases of heart failure, it is not as directly indicative of LHF as pulmonary edema.

C. Peripheral edema is more characteristic of right heart failure, where blood backs up in the systemic circulation.

D. Pulmonary edema is a hallmark finding in left heart failure as the left ventricle fails to pump effectively, causing fluid to accumulate in the lungs due to back pressure from the left atrium into the pulmonary veins.
