(type 4) conversion of lab values

5. mEq and mOsmol 5.1) mEq 5.1.1) mEq - General

5.1.1.1) mEq from weight/volume Normal 1


Total tried:       Correct:       Wrong:

The normal blood level of Cl- is 96 - 106 mEq/L. A patient is suffering from hypochloremia , and the blood level is found to be 82.91 mEq/L. Express this in mg/dL unit.

lb equals 294.3305 mg/dL kg

    The term deci liter (dL) means tenth of a liter, or, 100 mL. For Cl- , the atomic weight is 35.5 and the valence is 1. Therefore, we can write:
    35.5 mg = 1 mEq.
    This fraction `(35.5 \quad mg)/(1 \quad mEq)` will be used in this problem. Using dimensional analysis, we can write: `(82.91 \quad mEq)/(1 \quad L) × (35.5 \quad mg)/(1 \quad mEq) × (1 \quad L)/(1000 \quad mL) × (100 \quad mL)/(1 \quad dL) `

    `= (294.3305 \quad mg)/(dL)` Ans.
