Have patient swallow slowly and frequently
A. Have patient sit up and lean forward
Unstable, plaque, a condition of atherosclerotic heart disease, occurs in unstable angina and myocardial infarction. Unstable plaque can rupture, causing platelet aggregation and thrombus formation. What are the major determinants of the vulnerability of plaque to rupture? Mark all that apply. A. Size of lipid-rich core. B. Preponderance of smooth muscle cells C. Presence of inflammation D. Decrease in blood pressure and coronary blood flow E. Thickness of fibrous cap
A. Size of lipid-rich core. C. Presence of inflammation E. Thickness of fibrous cap
When an acute myocardial infarction (MI) occurs, many physiological changes occur very rapidly. What causes the loss of contractile function of the heart within seconds of the onset of an MI? A. conversion from aerobic to anaerobic metabolism. B. Overproduction of energy capable of sustaining normal myocardial function. C. Conversion from anaerobic to aerobic metabolism. D. Inadequate production of glycogen with mitochondrial shrinkage.
A. conversion from aerobic to anaerobic metabolism.
The diagnosis of chronic stable angina is based on a detailed pain history, the presence of risk factors, invasive and noninvasive studies, and lab studies. What test is not used in the diagnosis of angina? A. serum biocheimcal markers B. Cardiac catheterization C. Echocardiogram D. Nuclear imaging studies
A. serum biocheimcal markers
Unstable angina/non-ST segment elevation myocardial infarction is a clinical syndrome that ranges in severity between stable angina to myocardial infarction (MI). It is classified according to its risk of causing an acute MI and is diagnosed based on what? Mark al that apply. A. severity of pain and abruptness of onset B. Serum biomarkers C. Coexisting chronic conditions D. ECG pattern E. Blood flow angiography
A. severity of pain and abruptness of onset D. ECG pattern
St-elevated myocardial infarction (STEMI) is accompanied by sever, crushing pain. Morphine is the drug of choice used to treat the pain of STEMI when the pain cannot be relieved with oxygen and nitrates. Why is morphine considered the drug of choice in STEMI? A. Action increases autonomic nervous system activity. B. Action decrease metabolic demands of the heart C. Action increases anxiety, thus increasing metabolic demands of heart. D. Action relieves pain and gives sense of depression.
B. Action decrease metabolic demands of the heart
Heart failure in an infant usually manifests itself as tachypnea or dyspnea, both at rest and on exertion. When does this most commonly occur with an infant? A. During bathing B. During feeding. C. During burping D. during sleep
B. During feeding.
It is known that more than 100 distinct myocardial disease can demonstrate clinical features associated with dilated cardiomyopathy DCM. What is the most common identifiable cause of DCM in the US? A. Hepatic cardiomyopathy B. alcoholic cardiomyopathy C. Cardiotoxic cardiomyopathy D. Exercise-induced cardiomyopathy
B. alcoholic cardiomyopathy
During an acute myocardial infarction (MI), there is ischemic damage to the hear muscle. The location and extent of the ischemic damage is the major predictor of complications ranging from cardiac insufficiency to death, following an MI. What is the "window of opportunity" in restoring blood flow to the affected area so as to diminish the ischemic damage to the heart and maintain the viability of the cells? A. 10-20min B. 30-40min C. 20-40min D. 10-30min
C. 20-40min
Tetralogy of Fallow is a congenital condition of the heart that manifests in four distinct abnormalities of the infant heart. It is considered a cyanotic heart defect due to the right to left shunting of the blood through the ventricular septal defect. A hallmark of this condition is the "tet spells" that occur in these children. What is a tet spell? A. A stressful period right after birth that occurs without evidence of cyanosis. B. A hyperoxygenated period when the infant is at rest. C. A hypercyanotic attack brought on by period of stress D. A hyperpneic attack in which the infant loses consciousness.
C. A hypercyanotic attack brought on by period of stress
The scar tissue that occurs between the layers of pericardium becomes rigid and constrictive from scar tissue in constrictive pericarditis. What is a physiologic sign of constrictive pericarditis? A. Kussmaul breathing B. Pulsus paradoxus C. Kussmaul sign D. Widening pulse pressure
C. Kussmaul sign
In infective endocarditis, vegetative lesions grow on the valves of the heart. These vegetative lesions consist of a collection infectious organisms and cellular debris enmeshed in the fibrin strands of clotted blood. What are the possible systemic effects of these vegetative lesions? A. They can block the heart valves from closing completely. B. They can keep the heart valves from opening. C. They can fragment and cause cerebral emboli. D. The can fragment and make lesions larger.
