Several daysafter returning home, she awoke with swelling and pain in her right leg and her leg was blue.She went immediately to the emergency room where an examination showed an extensivedeep vein thrombosis involving the femoral and iliac veins on the right side. Followingresolution of the clot, this patient will require which treatment in the future?Select one:a.Aspirinb.Warfarinc.Vitamin Kd.Continual heparin infusionFeedbackYour answer is correct.this clot is due to stasis of blood flow in her venous circulation. Heparin is used forthe prevention of a clot, but has to be infused. is anticoagulation occurs by heparinbinding to antithrombin III and the subsequent inactivation of thrombin. A continuousheparin drip is impractical. Warfarin is used to inhibit the formation of vitamin Kclotting factors and would prevent the formation of any clot. Aspirin is used toprevent activation of platelets. e current clot is not due to activation of platelets.Vitamin K will be used to restore clotting factors that may be decreased after warfarintreatment. is patient has sufficient clotting factors as evidenced by her venous clot.The correct answer is:Warfarin2

e.D → XFeedbackYour answer is correct.A normal Starling curve of the heart, showing stroke volume as a function of end-diastolic volume, is depicted by the curve on which an X is marked. The Starlingcurve below the normal one will result from a decrease in contractility (e.g., withheart failure) or an increase in afterload. The Starling curve above the normal curvewill result from an increase in contractility or a decrease in afterload. Digitalis is apositive inotropic agent that will cause a point on the lower curve to shift to up and tothe left, such that there is an increased stroke volume at a lower preload.The correct answer is:D → XQuestion3CorrectMark 1.00 out of 1.00Flag questionQuestion textWhich of the following agents or changes has a negative inotropic effect on the heart?Select one:
