A patient has a serum potassium level of 2.6 mmol/L, muscle weakness and prominent U waves. Potassium chloride is prescribed intravenously. Which action is correct?
Correct answer: B. Dilute it and give it using an infusion pump
- A. Administer it by rapid intravenous push
- B. Dilute it and give it using an infusion pump
- C. Mix it with blood in the transfusion line
- D. Give it without cardiac monitoring if pain occurs
Explanation
Intravenous potassium chloride must be diluted and administered at a controlled rate with appropriate monitoring because rapid administration can cause fatal dysrhythmias. Potassium chloride must never be given by intravenous push.
