Classification: cardiovascular agent,cardiac glycoside; antiarrhythmic Generic Name: DIGOXIN Expected Pharmacological Action: Medical definition & Lay terminology; It inhibits Na-K ATPase, which in turn causes an increased availability of intracellular calcium in the myocardium and conduction system. Inotropy and automaticity are subsequently increased while conduction velocity is reduced. Usual Dose: adult; 10-15 mcg/kg [ 1 mg] in divided dose over 24-48 hours Child; ＜ 2y, 40-60mcg/kg, 2-10y,20-40mcg/kg; 10y, 10-15 mcg/kg [ 1.5-2 mg] Neonate; 30-50 mcg/ 0.0625mg[lanoxin only]. Premature; 20 mcg/kg. Tab Usual routes: PO/IV Therapeutic Uses: Adverse Effects: Expected Common Increase the contractility of the heart muscles headache It increase baroreceptor sensitization nausea It allows progressive efflux of intracellular Potassium, which will increase serum potassium level dizziness Adverse Effects Requiring Nursing Action: Adverse Effects Action: Prevention/Assessment/Intervention Heart block Should only be use in heart failure to avoid recurrence of failure of the heart Cardiac dysrhythmia Monitor serum concentration when used to control rate of atrial fibrillation Arrhythmia in children Avoid rapid IV administration in digitalized patients;may produce serious arrhythmias tachycardia Used caution in patient with acute myocardial infarction may increase myocardial oxygen Likely Medication/Food Interactions: Don’t give Parkinson's patients unless conduction accessory pathway has been surgically disable. Use in extreme in the elderly and those with acute myocardia infarction Administration/Interventions/Evaluation of Effectiveness/Laboratory Work Obtain baseline data [HR and rhythm,bp,and electrolyte levels] and ask patient about the use of cardiac glycosides. Take and record apical-redial pulse for sudden increase or decrease in pulse rate,pulse deficit,irregular beat and report to the physician Patient Education: What will the safe nurse teach the client to DO or expect or report? Tell patient to report pulse rate less than 60 bpm or more than 110 bpm Advice patients to avoid using herbal supplements Tell patient not to substitute one brand for another Citations: lippincott advisor for education, Taylor fundamental of nursing, ninth edition
