Increase intake of sodium

Contact the health care provider for heart rate less than 60/min

Take the medication with food if you develop nausea

Answer and Explanation

The Correct Answer is C

A. Checking the pulse rate for 30 seconds and multiplying by 2 may not be accurate enough for a medication like digoxin, which requires precise monitoring.
B. Increasing sodium intake is not recommended for heart failure patients as it can worsen fluid retention and exacerbate symptoms.
C. Digoxin can cause bradycardia; therefore, it is crucial for clients to monitor their heart rate and contact their healthcare provider if it falls below 60/min to avoid adverse effects.
D. Taking digoxin with food can help with nausea but is not as critical as monitoring heart rate for potential toxicity.
