Final answer:
High-risk patients for VTE include those who are wheelchair-bound, have undergone prolonged surgeries, are morbidly obese, and those with severe heart failure due to factors such as immobilization and reduced blood flow.
Step-by-step explanation:
Patients at high risk for venous thromboembolism (VTE) include those with certain medical conditions and lifestyle factors that increase their likelihood of developing a thrombus. Specifically, the following patients are considered to be at high risk for VTE:
- Wheelchair-bound patients are at risk due to venous stasis due to immobilization.
- Patients who underwent prolonged surgical procedures are at risk because of the extended period of immobilization during and after surgery which can lead to slower blood flow and potential clot formation.
- Morbidly obese patients have an increased risk as obesity is associated with various factors such as inflammation and increased pressure in the veins that may contribute to the formation of blood clots.
- Patients with a humerus fracture may not be at as high a risk as the other categories unless it results in prolonged immobilization or if other risk factors are present.
- Patients with severe heart failure are at an increased risk due to reduced cardiac function which can result in slower blood flow and potential for venous thrombosis.
From this list, wheelchair-bound patients, patients who underwent prolonged surgical procedures, morbidly obese patients, and patients with severe heart failure are considered to be at high risk for VTE.
