Question 32 5 /^5 pts
Question 31 5 /^5 pts
Your patient has a diagnosis of atherosclerosis. Is your patient at a higher or lower risk for a thromboembolism? Explain your reasoning. Your Answer: They would be at higher risk of a thromboembolism. This is because one with atherosclerosis has an accumulation of fatty deposits in their arteries, which can build-up, called plaque. The plaque can cause blood clots to form on the wall of the artery and it can even disloge, causing issues for the rest of the body depending on where it settles. 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.
