6 Which of the following statements describes how thromboembolism affects stroke patients? A) Venous thromboembolism (VTE) is difficult to diagnose in older patients, in part due to reduced sensitivity in patients B) VTE is an uncommon problem in stroke patients whereas symptomatic thromboembolism is nearly guaranteed C) Fatal pulmonary embolism occurs in 50% of all patients suffering from untreated deep vein thrombosis (DVT) D) Heparin is not effective at treating DVT, and it increases the risk of hemorrhage

An 18-year-old high school football player suffered a torn anterior cruciate ligament (ACL) in the state playoffs. After undergoing repair, he found it difficult to ambulate with the knee brace. Weighing close to 140 kg (approximately 300 pounds), the athlete found it difficult to stand and balance on one leg. His mother was unable to support him by herself. After 1 week, the young man began to have increased pain and swelling in the calf of his affected leg. In the middle of the night, the teen called out to his mother, complaining of shortness of breath and unexplained anxiety. His mother called 9-1-1, and he was taken to a local hospital. In the emergency department, he was diagnosed with a deep vein thrombosis and a pulmonary embolism. Oxygen and low-molecular-weight heparin were administered, and the young man was admitted to the intensive care unit. As a result of the thrombus lodging in the pulmonary circulation, the sympathetic nervous system is activated. Hemodynamically, this results in: A. vasodilation. B. embolization. C. decreased pulmonary artery pressure. D. right heart failure.

A 25-year-old white female reports to the Emergency Room because of sharp left-sided chest pain and shortness of breath of one-day duration. The patient was in excellent health until yesterday. She was awakened from her sleep by sharp left-sided chest pain. The pain worsened with motion and deep breathing. The pain has been progressively increasing in severity, and she now has severe left shoulder pain. She complains of shortness of breath and is very apprehensive about dying. She denies any cough, fever, sputum production, or hemoptysis. She is married and had one normal delivery three years ago. She is currently on birth control pills. She has never been hospitalized except for labor and delivery. Review of systems is negative. She denies any past history of venous problems. She reveals having a similar transitory minor episode of chest pain approximately one year ago while she was vacationing in Michigan. She works as a computer programmer. She smokes one pack of cigarettes a day for the past eight years. She considers herself a social drinker. What can you reasonably conclude given the above information: (select all that apply) A. She is at risk for a cerebral vascular accident due to brain embolism if the DVT moves to her brain. B. Her history, signs, and symptoms are consistent with a pulmonary embolism due to an embolized DVT. C. Smoking and a sedentary job that requires hours of sitting have increased her risk for deep vein thrombosis. D. Underlying pathology was most likely due to turbulence (vs stasis) of venous flow. E. If blood flow from the right ventricle is significantly impeded, as in a saddle thrombus, she could be at risk for cardiovascular collapse.

Sensation is decreased over the left upper and lower extremities. Which of the following additional findings is most likely in this patient? A) Patent ductus arteriosus B) Patent ductus venous C) Patent foramen ovale D) Pulmonic stenosis E) Ventricular septal defect
