Correct answer: A. Place the patient on continuous cardiac monitoring

  • A. Place the patient on continuous cardiac monitoring
  • B. Encourage potassium-rich fruit and fruit juice
  • C. Administer a prescribed potassium supplement
  • D. Remove the cardiac monitor to reduce anxiety

Severe hyperkalaemia with ECG changes can rapidly cause fatal dysrhythmias, so continuous cardiac monitoring and urgent medical escalation are essential. Potassium intake and supplements are unsafe, and removing monitoring increases the risk of missing deterioration.
