Question

Given below are two statements, one is labelled as Assertion A and the other is labelled as Reason R
Assertion A: Measurement of plasma or serum potassium is not a reliable indicator of body potassium status
Reason R: Potassium being intracellular cation, estimation of potassium in RBCs gives better reflection of body potassium status
In light of the above statements, choose the correct answer from the options given below:

• A. Both A and R are true and R is the correct explanation of A
• B. Both A and R are true but R is NOT the correct explanation of A
• C. A is false but R is true
• D. A is true but R is false

Hint:

Since \( 98\% \) of potassium is intracellular, extracellular (serum) levels can be normal or high even in the presence of severe total-body potassium depletion.

Answer 1

The Correct Option is A
