Cardiology PACKRAT Questions | 100% Correct Answers | Verified | Latest 2024 Version

1. History & Physical/Cardiology Which of the following conditions would cause a positive Kussmaul's sign on physical examination? Answers A. Left ventricular failure B. Pulmonary edema C. Coarctation of the aorta D. Constrictive pericarditis - (u) A. Left ventricular failure results in the back-up of blood into the left atrium and then the pulmonary system so it would not be associated with Kussmaul's sign. (u) B. Pulmonary edema primarily results in increased pulmonary pressures rather than having effects on the venous inflow into the heart. (u) C. Coarctation of the aorta primarily affects outflow from the heart due to the stenosis resulting in delayed and decreased femoral pulses; it has no effect on causing Kussmaul's sign. (c) D. Kussmaul's sign is an increase rather than the normal decrease in the CVP during inspiration. It is most often caused by severe right-sided heart failure; it is a frequent finding in patients with constrictive pericarditis or right ventricular infarction. 2. History & Physical/Cardiology Anginal chest pain is most commonly described as which of the following? Answers A. Pain changing with position or respirationB. A sensation of discomfort C. Tearing pain radiating to the back D. Pain lasting for several hours - (u) A. Pain changing with position or respiration is suggestive of pericarditis. (c) B. Myocardial ischemia is often experienced as a sensation of discomfort lasting 5-15 minutes, described as dull, aching or pressure. (u) C. Tearing pain with radiation to the back represents aortic dissection. (u) D. Chest pain lasting for several hours is more suggestive for myocardial infarction. 3. History & Physical/Cardiology Eliciting a history from a patient presenting with dyspnea due to early heart failure the severity of the dyspnea should be quantified by Answers A. amount of activity that precipitates it. B. how many pillows they sleep on at night. C. how long it takes the dyspnea to resolve. D. any associated comorbidities. - (c) A. The amount of activity that precipitates dyspnea should be quantified in the history. (u) B. Orthopnea or paroxysmal nocturnal dyspnea can be quantified by how many pillows a patient needs to sleep on to be comfortable. (u) C. How long dyspnea takes to resolve or associated comorbidities has no bearing on quantifying the severity of dyspnea. (u) D. See answer C above.4. History & Physical/Cardiology A 25 year-old female presents with a three-day history of chest pain aggravated by coughing and relieved by sitting. She is febrile and a CBC with differential reveals leukocytosis. Which of the following physical exam signs is characteristic of her problem? Answers A. Pulsus paradoxus B. Localized crackles C. Pericardial friction rub D. Wheezing - (u) A. Pulsus paradoxus is a classic finding for cardiac tamponade. (u) B. Localized crackles are associated with pneumonia and consolidation, not pericarditis. (c) C. Pericardial friction rub is characteristic of an inflammatory pericarditis. (u) D. Wheezing is characteristic for pulmonary disorders, such as asthma. 5. History & Physical/Cardiology A 65 year-old white female presents with dilated tortuous veins on the medial aspect of her lower extremities. Which of the following would be the most common initial complaint? Answers A. Pain in the calf with ambulation B. Dull aching heaviness brought on by periods of standing C. Brownish pigmentation above the ankle D. Edema in the lower extremities - (u) A. Patients with deep venous thrombosis (DVT) may present with complaints of pain in the calf with ambulation. Secondary varicosities may result from DVT's.(c) B. Dull aching heaviness or a feeling of fatigue brought on by periods of standing is the most common complaint of patients presenting initially with varicosities. (u) C. Stasis Dermatitis and edema are most suggestive of chronic venous insufficiency. (u) D. See C for explanation. 6. History & Physical/Cardiology A 22 year-old male received a stab wound in the chest an hour ago. The diagnosis of pericardial tamponade is strongly supported by the presence of Answers A. pulmonary edema. B. wide pulse pressure. C. distended neck veins. D. an early diastolic murmur. - (u) A. Pulmonary edema may result with low output states as seen with myocardial contusions, but it is not strongly suggestive of tamponade.
