Which of the following is recommended patient teaching for ARBs?

• A. Avoid salt substitutes and foods high in potassium
• B. Increase potassium-rich foods
• C. Take NSAIDs daily
• D. Stop medication if you feel thirsty

Answer: (B)

ARBs can raise potassium levels because they block angiotensin II receptors, which reduces aldosterone activity and decreases potassium excretion in the kidneys. The main teaching is to limit potassium intake by avoiding potassium-rich foods and salt substitutes that contain potassium, to prevent hyperkalemia. This helps protect against potential heart rhythm problems. Also, don’t add potassium supplements or use potassium-containing salt substitutes without talking to a healthcare provider, especially if kidney function is a concern or other meds that raise potassium are being used. If you notice symptoms like muscle weakness, fatigue, or an irregular heartbeat, seek medical advice promptly.
