Question

How does pseudo-hyperkalemia lead to apparent hyperkalemia on laboratory measurements?

a) Pseudohyperkalemia results from true potassium excess in the blood.
b) Hemolysis during blood sample collection causes potassium to leak from red blood cells into the serum, leading to artificially elevated potassium levels.
c) Pseudohyperkalemia is a medical term for low potassium levels.
d) Pseudohyperkalemia is a genetic condition and not related to blood sample collection.

Answer 1

Pseudo-hyperkalemia is a condition where leakage of potassium from red blood cells into the serum during blood sample collection can artificially elevate measured potassium levels, resulting in apparent hyperkalemia.

Step-by-step explanation:

Pseudo-hyperkalemia is a condition that can lead to apparent hyperkalemia on laboratory measurements. It occurs when there is a leakage of potassium from red blood cells into the serum during blood sample collection. This leakage can artificially elevate the measured potassium levels in the blood, giving the appearance of hyperkalemia.
