Answer to Question 1

ANS: B
Fibrinolytic agents such as streptokinase dissolve or lyse recently formed thrombi. The goals of thrombolytic therapy are to lyse the thrombus during the early stages of clot formation, restore circulation to the areas distal to the thrombus, and reduce morbidity after thromboembolism formation. Fibrinolytic agents do not have an effect on myocardial oxygenation and do not promote platelet aggregation or inhibit clotting mechanisms.

Answer to Question 2

ANS: A, B, D, E
Before beginning therapy with pentoxifylline, the nurse should determine intolerance to caffeine. To evaluate therapeutic effects of prescribed medications, a baseline is needed against which to compare future assessments. Before beginning therapy with pentoxifylline, the nurse should determine baseline gastrointestinal symptoms and assess for cardiac symptoms, pain, and dizziness. Bleeding times do not apply to therapy with this drug. Exercise stress testing is not part of the premedication assessment.
