WCU Pathophysiology Midterm Exam 2024 A patient is diagnosed with heart failure with normal ejection fraction. This patient is most likely characterized by a(n) - Answer-elderly woman without a previous history of MI. In which dysrhythmias should treatment be instituted immediately? - Answer-Atrial fibrillation with a ventricular rate of 220 beats/minute Aortic regurgitation is associated with - Answer-diastolic murmur. Mitral stenosis is associated with - Answer-a pressure gradient across the mitral valve. First-degree heart block is characterized by - Answer-prolonged PR interval. Which blood pressure reading is considered to be indicative of prehypertension according to the JNC-7 criteria? - Answer-128/82 Increased preload of the cardiac chambers may lead to which patient symptom? - Answer- Edema Beta-blockers are advocated in the management of heart failure because they - Answer-reduce cardiac output. Hypotension associated with neurogenic and anaphylactic shock is because of - Answer- peripheral pooling of blood. While hospitalized, an elderly patient with a history of myocardial infarction was noted to have high levels of low-density lipoproteins (LDLs). What is the significance of this finding? - Answer-Increased LDL levels are associated with increased risk of coronary artery disease. Hypertension is closely linked to - Answer-obstructive sleep apnea. In which stage of shock is a patient who has lost 1200 mL of blood, who has normal blood pressure when supine, but who experiences orthostatic hypotension upon standing? - Answer- Class II, Compensated Stage Administration of which therapy is most appropriate for hypovolemic shock? - Answer- Crystalloids Which finding is indicative of orthostatic hypotension in a person with a supine blood pressure (BP) of 110/70 and a heart rate (HR) of 100? - Answer-Sitting BP 88/60, HR 118 A patient is diagnosed with cardiogenic shock. The patient is hyperventilating and is therefore at risk for the respiratory complication of respiratory acidosis. - Answer-False A patient diagnosed with cardiogenic shock who is hyperventilating is at risk for respiratory alkalosis.
