What drug class is digoxin? cardiac glycoside Digoxin mechanism of action 1. Inhibits sodium/potassium pump, thereby increasing intracellular calcium levels 2. Positive inotropic effect, increases cardiac output 3. Decreases chronotropy and dromotropy; slows AV conduction Indications for digoxin systolic heart failure, atrial fibrillation Adverse effects of digoxin Dysrhythmias, cardiotoxicity, hypotension, bradycardia, GI effects (nausea, vomiting, and abdominal pain), CNS effects includin...

MS II Prep U Ch. 26: Management of Patients With Dysrhythmias and Conduction Problems A home care nurse is visiting a left-handed client who has an implantable cardioverter-defibrillator (ICD) implanted in his left chest. The client tells the nurse how excited he is because he's planning to go rifle hunting with his grandson. How should the nurse respond? "Enjoy your time with your grandson." "You can't shoot a rifle left-handed because the rifle's recoil will traumatize the ICD s...
