Question 1 of 5
The physician has ordered DDAVP (desmopressin acetate) for a client with diabetes insipidus. Which finding indicates that the medication is having its intended effect?
Correct Answer: C
Rationale: DDAVP reduces excessive urination in diabetes insipidus by mimicking antidiuretic hormone, decreasing urinary output. Appetite, blood sugar, and activity are not directly affected.
Question 2 of 5
A female client is started on warfarin (Coumadin) 5 mg po bid. To adequately evaluate the effectiveness of the warfarin therapy, the nurse must know that this medication:
Correct Answer: C
Rationale: Thrombolytic agents (e.g., streptokinase) directly activate plasminogen, dissolving fibrin deposits, which in turn dissolves clots that have already formed. Heparin prevents the formation of clots by potentiating the effects of antithrombin III and the conversion of prothrombin to thrombin. Warfarin prevents the formation of clots by interfering with the hepatic synthesis of the vitamin K-dependent clotting factors. Platelets initiate the coagulation of blood by adhering to each other and the site of injury to form platelet plugs.
