Answer to Question 1
B
Dysrhythmic activity in the atria does not significantly reduce cardiac output but can be danger-ous when dysrhythmic impulses cross the AV node, causing ventricular dysrhythmias, which can be life threatening. Treating ventricular dysrhythmia helps improve ventricular pumping. These drugs do not restore normal sinus rhythm. To prevent stroke, an anticoagulant, such as warfarin, is used. Slowing ventricular contraction does not affect the rate of atrial contraction. Restoring normal sinus rhythm requires cardioversion, short-term treatment with amiodarone or sotalol, or RF ablation of the dysrhythmia source.
Answer to Question 2
OMG..This is soo helpful. Thank you.
Answer to Question 3
B, C, E
The autoimmune response causes the immune system to attack the body's own cells. The hyper-sensitivity response, mediated by IgE, causes the release of harmful chemical mediators. Recog-nition of MHC molecules as nonself in a transplanted organ can cause organ rejection. Activation of the complement system causes a cascade of reactions that assist in the immune response. Opsonization is a process that assists with phagocytosis.
