A patient with chronic kidney disease is preparing for hemodialysis. Which laboratory result requires the closest immediate attention before treatment?
Correct answer: A. Serum potassium of 6.2 mmol/L
- A. Serum potassium of 6.2 mmol/L
- B. Haemoglobin of 10.2 g/dL
- C. Serum phosphate of 5.1 mg/dL
- D. Blood urea nitrogen of 58 mg/dL
Explanation
A markedly elevated potassium level can cause life-threatening cardiac dysrhythmias, so it requires urgent assessment and treatment. Anaemia, phosphate elevation, and urea elevation are common in chronic kidney disease but are generally less immediately dangerous than severe hyperkalaemia.
