Answer to Question 1
3
Rationale: The normal heart rate is 60 to 100 beats/min in an adult. If the nurse notes a heart rate that is less than 60 beats/min, the nurse would not administer the digoxin and would further evaluate the client for signs and symptoms of digoxin toxicity. When clients are bradycardic, they may have symptoms of decreased cardiac output so this would also be assessed.
Answer to Question 2
4
Rationale: The normal cardiac output for the adult can range from 4 to 7 L/min. Therefore a cardiac output of 3.2 L/min is below normal range.
