A nurse teaches a client who is prescribed digoxin (Lanoxin) therapy. Which statement should the nurse include in this client's teaching?
a. "Avoid taking aspirin or aspirin-containing products."
b. "Increase your intake of foods that are high in potassium."
c. "Hold this medication if your pulse rate is below 80 beats/min."
d. "Do not take this medication within 1 hour of taking an antacid."
ANS: D
Gastrointestinal absorption of digoxin is erratic. Many medications, especially antacids, interfere with its absorption. Clients are taught to hold their digoxin for bradycardia; a heart rate of 80 beats/min is too high for this cutoff. Potassium and aspirin have no impact on digoxin absorption, nor do these statements decrease complications of digoxin therapy.
