s s Your patient has a diagnosis of atherosclerosis. Is your patient at a higher or lower risk for a thromboembolism? Explain your reasoning. Your Answer: Patient with atherosclerosis has the built up fat materials in the vessels, which form plaque in the interior wall. The built up plaque can interfere with the blood flow and have high risk of blood clots. Thromboembolism has the dislodged blood clot lodge the vessel as it travels. Hence, patient with atherosclerosis diagnosis will have higher risk for thromboembolism. Higher risk. Thromboembolism is an embolus that becomes lodged in a vessel as it travels. Atherosclerosis is an accumulation of soft masses of fatty materials, often cholesterol, inside arteries. These deposits called plaque accumulate beneath the inner linings of arteries. Plaque can cause a clot to form on the irregular arterial wall. If the clot becomes dislodged it can travel and clog a smaller artery in its path. ‘Question 32 5/5pts Your patient is admitted to the hospital for a coronary artery bypass.
