If a study participant were administered 12 μEq/L of a drug in blood.One hour later you found the concentration reduced to 11μEq/L and another hour later you found the concentration reduced to 10μEq/L.Based on these observations,you should conclude:
A) the participant had taken an additional dose of the drug.
B) the drug's elimination rate follows first-order kinetics.
C) the drug's elimination rate follows zero-order kinetics.
D) the participant is a poor metabolizer.

The drug's elimination rate follows zero-order kinetics because the concentration decreases by a constant amount (1 μEq/L) per hour, rather than a percentage of the remaining concentration.
