Final answer:
The client's lab values indicate hypokalemia, an abnormally decreased level of potassium in the blood, as the K+ level is 1.9 which is below the normal range. There are no indications of hypernatremia, myelosuppression, or leukopenia given the other lab values provided are within or near normal ranges.
Step-by-step explanation:
A client's lab values are presented with certain elements highlighted: Hemoglobin (Hgb) is 12.6, Potassium (K+) is 1.9, Uric Acid is 7.0, Sodium (Na+) is 136, and Platelets are 178. The value of concern here is the potassium level. Normal blood potassium levels are typically between 3.5 to 5.0 milliequivalents per liter (mEq/L), and the client's level is 1.9 mEq/L, which indicates a condition called hypokalemia, characterized by abnormally decreased blood levels of potassium.
Hypernatremia is not indicated as the sodium level is within the normal range (135-145 mEq/L), and there is no suggestion of myelosuppression or leukopenia as the white blood cell count is not provided, but the given information does not point toward these conditions.
The clinical consequences of hypokalemia can be serious, potentially causing muscular weakness, cramps, and cardiac arrhythmias. Treatment of hypokalemia involves correcting the potassium deficit, which may require oral or intravenous potassium supplements, along with addressing the underlying cause of the deficiency.
