Which statement demonstrates correct self-management for a patient on Digoxin?

• A. I should limit foods high in potassium.
• B. I should not take this medication if my heart rate is below 70 bpm.
• C. I should measure my pulse before each dose and hold if below 60 bpm.
• D. I should avoid taking this medication at night.

Answer: (C)

The main idea here is safe self-management with a drug that has a narrow therapeutic window and can slow the heart. Digoxin can cause or worsen bradycardia, so the patient must monitor the heart rate and only take the dose if the rate is not dangerously low. Measuring the pulse before each dose and withholding the dose if the rate is below 60 beats per minute is the prudent, correct action. If the pulse is 60 or higher, take the medication as prescribed and don’t double doses.

It’s also important to maintain normal potassium levels, because electrolyte imbalances can increase the risk of digoxin toxicity, but this doesn’t translate to restricting potassium-rich foods as a blanket rule. Other options aren’t aligned with safe practice: setting a higher threshold like 70 bpm for withholding isn’t supported, and there’s no general rule to avoid taking digoxin at night—the timing should be consistent with the prescribed plan.
