Portage Learning Pathophysiology NURS 231 BIOD 331 Module 1-10 Exam with Questions and Answers The nurse is caring for a patient with atrial fibrillation (AF). In addition to an antidysrhythmic, what medication does the nurse plan to administer? a) Atropine b) Dobutamine c) Heparin d) Magnesium sulfate ANSWER c) Heparin *AFib is the loss of coordinated atrial contractions that can lead to pooling of blood, resulting in thrombus formation. The patient is at high risk for pulmonary and systemic embolism. Heparin and other anticoagulants (e.g., enoxaparin [Lovenox], warfarin [Coumadin], dabigatran [Pradaxa], rivaroxaban [Xarelto], apixaban [Eliquis], or edoxaban [Savaysa]) are used to prevent thrombus development in the atrium, leading to the risk of embolization (i.e., stroke) *Atropine is used to treat bradycardia to increase HR, not rapid HR r/t afib *Dobutamine is an inotropic agent used to improve CO; it may cause tachycardia, thereby worsening atrial fibrillation. *Although electrolyte levels are monitored in clients with dysrhythmia, magnesium sulfate is not used unless depletion is noted. Match the following: 1) ____Atrial tachycardia, HR 212, patient lethargic, BP 82/60 2) ____Sinus Bradycardia, patient is diaphoretic, BP 88/50 3) ____Sinus Bradycardia, no symptoms 4) ____Ventricular fibrillation
