A patient with renal failure has a potassium level of 6.8 mmol/L and peaked T waves on the ECG. Which action should the nurse take first?
Correct answer: A. Place the patient on continuous cardiac monitoring
- A. Place the patient on continuous cardiac monitoring
- B. Encourage the patient to eat potassium-rich fruit
- C. Administer prescribed potassium replacement immediately
- D. Give a salt substitute instead of the prescribed diet
Explanation
Severe hyperkalaemia with peaked T waves indicates an immediate risk of life-threatening cardiac dysrhythmia. Continuous cardiac monitoring and urgent notification support rapid treatment, which may include intravenous calcium and measures to shift or remove potassium. Potassium-rich foods, potassium replacement and many salt substitutes can worsen the condition.
