A patient has a serum potassium level of 6.4 mmol/L and peaked T waves on the ECG. Which action should the nurse take first?
Correct answer: B. Place the patient on cardiac monitoring and notify the provider
- A. Encourage the patient to drink more water
- B. Place the patient on cardiac monitoring and notify the provider
- C. Ask the patient to walk to improve renal circulation
- D. Document the result and repeat it at the next routine check
Explanation
Severe hyperkalaemia with ECG changes can cause life-threatening cardiac dysrhythmias, so circulation and cardiac monitoring take priority. Increasing water intake or delaying notification does not treat the immediate cardiac risk.
