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.
Question :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.

to pulmonary hypertension

º 118/78
º 128/82
º 140/88
º 138/94

Question :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

Correct 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
