Question 1 of 5
A client with a history of heart failure is receiving Carvedilol (Coreg). The nurse should monitor the client for:
Correct Answer: A
Rationale: Carvedilol, a beta-blocker, can cause hypotension due to vasodilation and reduced heart rate. Hyperglycemia, tachycardia, and weight gain are not primary concerns.
Question 2 of 5
Which finding in the patient's history contraindicates the use of Imitrex (sumatriptan) for the prevention of migraine headaches?
Correct Answer: B
Rationale: Sumatriptan (Imitrex) is a vasoconstrictor contraindicated in patients with angina due to the risk of coronary artery vasoconstriction and ischemia. Diabetes renal calculi and peptic ulcer disease are not contraindications for sumatriptan.

She is scheduled to have a bone marrow aspiration tomorrow. She has had a bone marrow test previously and is apprehensive about having another. Which of the following interventions will be most effective in relieving her anxiety?

Question 5 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.
