A patient with peripheral vascular disease is receiving discharge instructions. Which of the following information should be included?

Correct Answer: C

Rationale: Patients with peripheral vascular disease should be advised to avoid crossing their legs as this can impede blood flow. Peripheral vascular disease, also known as arteriosclerosis obliterans, is primarily caused by atherosclerosis. Atherosclerosis results in the gradual progression of arterial occlusion due to the formation of atheromas. Crossed legs can further restrict blood flow, exacerbating the condition. Walking barefoot should be discouraged to prevent potential injuries to the feet. Using a heating pad can lead to burns and should be avoided to prevent thermal injuries. While using antibacterial ointment for skin lesions may be beneficial, it is not the priority instruction for patients with peripheral vascular disease.

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.

Correct Answer: C

Rationale: Osgood-Schlatter disease occurs in adolescents during the rapid growth phase when the infrapatellar ligament of the quadriceps muscle pulls on the tibial tubercle, causing pain and swelling in the inferior aspect of the knee. The condition is commonly caused by activities that require repeated use of the quadriceps, such as track and soccer. Choice A is incorrect because Osgood-Schlatter disease is not specifically linked to competitive swimming. Choice B is incorrect as surgical intervention is not usually necessary for this condition. Choice D is incorrect as the student is not trying to avoid physical education but is restricted from participating in sports due to the diagnosis of Osgood-Schlatter disease.
