Question

a patient presents with laboratory abnormalities including increased blood urea nitrogen and increased sodium and potassium. what follow - up test would be appropriate to run?
a) protein electrophoresis
b) hepatitis panel
c) kub x - ray
d) creatinine clearance rate
e) ekg

Explanation:

• Increased blood urea nitrogen (BUN) and electrolyte (sodium and potassium) abnormalities often suggest kidney dysfunction.
• Creatinine clearance rate is a key test to assess kidney function.
• Protein electrophoresis is more for analyzing proteins in the blood (e.g., in multiple myeloma).
• Hepatitis panel is for liver - related hepatitis viruses.
• KUB x - ray (Kidneys, Ureters, Bladder) gives a structural view but not a functional assessment like creatinine clearance.
• EKG is for heart electrical activity.

Answer:

d) Creatinine Clearance Rate
