Which of the following conditions would cause a positive Kussmaul's sign on physical examination? A. Left ventricular failure B. Pulmonary edema C. Coarctation of the aorta D. Constrictive pericarditis Explanation 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. B. Pulmonary edema primarily results in increased pulmonary pressures rather than having effects on the venous inflow into the heart. 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. 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. History & Physical/Cardiology Anginal chest pain is most commonly described as which of the following? A. Pain changing with position or respiration B. A sensation of discomfort C. Tearing pain radiating to the back D. Pain lasting for several hours Explanation A. Pain changing with position or respiration is suggestive of pericarditis. B. Myocardial ischemia is often experienced as a sensation of discomfort lasting 5-15 minutes, described as dull, aching or pressure. C. Tearing pain with radiation to the back represents aortic dissection. D. Chest pain lasting for several hours is more suggestive for myocardial infarction. 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 A. amount of activity that precipitates
