A patient in the cardiac unit is concerned about the risk factors associated with atherosclerosis. Which of the following are hereditary risk factors for developing atherosclerosis?

Correct Answer: A

Rationale: A family history of heart disease is an inherited risk factor for developing atherosclerosis. This factor is not modifiable through lifestyle changes. Studies have shown that having a first-degree relative with heart disease significantly increases the individual's risk of developing atherosclerosis. Overweight, smoking, and age are not hereditary risk factors for atherosclerosis. Overweight and smoking are lifestyle-related risk factors, while age is a non-modifiable risk factor that increases with time but is not directly inherited.

Correct Answer: C

Rationale: The correct answer is 'A young woman.' Raynaud's disease is most common in young women and is often associated with rheumatologic disorders like lupus and rheumatoid arthritis. This disorder involves vasospasm of the arteries, leading to reduced blood flow to the fingers and toes. Typically, Raynaud's affects the fingers, and in some cases, it can affect the toes. Only rarely does it involve other body parts such as the nose, ears, nipples, and lips. Choices B, C, and D are less likely as Raynaud's disease predominantly affects young women, although it can occur in other demographic groups as well.

Correct Answer: B

Rationale: In a hospitalized patient on prolonged bed rest, the most likely cause of sudden onset shortness of breath and chest pain is pulmonary embolism. Pregnancy and prolonged inactivity both increase the risk of clot formation in the deep veins of the legs, known as deep vein thrombosis (DVT). These clots can dislodge and travel to the lungs, causing a pulmonary embolism. Myocardial infarction (Choice A) is less likely in a young patient without a significant history of atherosclerosis. Anxiety attacks (Choice C) may present with similar symptoms but are less likely in this context. Congestive heart failure (Choice D) is less probable given the acute onset of symptoms and absence of typical signs like peripheral edema in this case.

Correct Answer: B

Rationale: Cerebral hemorrhage is a significant complication associated with thrombolytic therapy in stroke treatment. Thrombolytic therapy aims to dissolve clots, but it increases the risk of bleeding, including cerebral hemorrhage. This risk is especially high when the therapy is administered quickly after a stroke, sometimes before confirming the type of stroke. Air embolism (Choice A) is not a common complication of thrombolytic therapy. Expansion of the clot (Choice C) and resolution of the clot (Choice D) are not expected outcomes of thrombolytic therapy; the therapy is specifically used to dissolve clots, not to expand or resolve them.

Correct Answer: A

Rationale: The correct answer is torticollis, characterized by the shortening of the sternocleidomastoid muscle, limiting the range of motion of the neck and causing the chin to point to the opposing side. Craniosynostosis is the premature closure of cranial sutures, leading to an abnormal head shape but not necessarily affecting head position. Plagiocephaly is flattening of one side of the head due to external forces or positioning, not muscle shortening. Hydrocephalus presents with an increased head size due to the accumulation of cerebrospinal fluid, not with a fixed head position.
