TEST BANK INTRODUCTORY CLINICAL PHARMACOLOGY 12TH EDITION By Susan M Ford 1. The nurse is preparing to administer protamine emergently to a client per instructions from the health care provider. The nurse concludes this is necessary due to an adverse reaction to which drug? A) Clopidogrel B) Heparin C) Alteplase D) Warfarin Answer: B Rationale: An overdosage of any anticoagulant may result in uncontrolled bleeding in the client. In most cases, discontinuation of the drug is usually sufficient to correct overdosage; however, if the bleeding is severe there are antidotes. Protamine is used to treat overdose of heparin and low– molecular-weight heparins (LMWHs). Vitamin K is used to treat the overdosage of warfarin. Alteplase and clopidogrel do not require antidotes.
