WCU Patho 370 CHYU: Week 3 Exam

patient has a history of falls, syncope, dizziness, and blurred vision. The patient's symptomology is most likely related to º hypertension. º hypotension. º deep vein thrombosis. º angina - Answer- Hypotension An example of an acyanotic heart defect is º tetralogy of Fallot. º transposition of the great arteries. º ventricular septal defect. º all right-to-left shunt defects. - Answer- Ventricular septal defect º In this condition, blood from the left ventricle leaks into the right ventricle because of a defect in the ventricular wall. This leakage causes extra pressure in the right ventricle resulting in pulmonary hypertension. Cor pulmonale refers to º bi-ventricular failure. º left ventricular hypertrophy secondary to lung disease. º right ventricular hypertrophy secondary to pulmonary hypertension. º right ventricular failure secondary to right ventricular infarction. - Answer- rRight ventricular hypertrophy secondary to pulmonary hypertension Low cardiac output to the kidneys stimulates the release of _____ from juxtaglomerular cells. º aldosterone º norepinephrine º angiotensinogen º renin - Answer- Renin Which blood pressure reading is considered to be indicative of prehypertension according to the JNC-7 criteria? º 118/78 º 128/82 º 140/88 º 138/94 - Answer- 128/82 In which dysrhythmias should treatment be instituted immediately? º Asymptomatic sinus bradycardia at a heart rate of 50 beats/minute º Fever-induced tachycardia at 122 beats/minute º Premature atrial complexes occurring every 20 seconds º Atrial fibrillation with a ventricular rate of 220 beats/minute - Answer- Atrial fibrillation with a ventricular rate of 220 beats/minute ºIt allows blood to become stagnant in the atria and may lead to formation of thrombi. This condition requires resuscitation because of the reduction in cardiac output 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? º Sitting BP 88/60, HR 118 º Sitting BP 108/68, HR 102 º Sitting BP 110/78, HR 98 º Sitting BP 120/80, HR 100 - Answer- Sitting BP 88/60, HR 118 Restriction of which electrolytes is recommended in the management of high blood pressure? º Calcium º Potassium º Sodium º Magnesium - Answer- Sodium Hypertension with a specific, identifiable cause is known as _____ hypertension. º primary º orthostatic º secondary º malignant - Answer- Secondary Critically ill patients may have parenterally administered vasoactive drugs that are adjusted according to their _____ pressure. º systolic º mean arterial º diastolic º pulse - Answer- Mean arterial ºThe mean arterial pressure is used to make incremental adjustments to vasoactive drugs The majority of cases of anaphylactic shock occur when a sensitized individual comes in contact with º perfumes. º incompatible blood products. º. animal proteins or dander. º antibiotics. - Answer- Antibiotics An abnormally wide (more than 0.10 second) QRS complex is characteristic of º paroxysmal atrial tachycardia. º supraventricular tachycardia. º junctional escape rhythm. º premature ventricular complexes. - Answer- Premature ventricular complexes ºThe QRS of the premature complex is prolonged (greater than 0.10 second) and bizarre in appearance. What compensatory sign would be expected during periods of physical exertion in a patient with limited ventricular stroke volume? º Hypotension º Bradycardia º Aortic regurgitation º Tachycardia - Answer- Tachycardia
