When evaluating an 82-year-old patient receiving hydrochlorothiazide (HydroDIURIL), what laboratory value deviations may be related to the medication?
A) Elevated uric acid levels
B) Reduced blood urea nitrogen (BUN) levels
C) A serum potassium level of 4.7 mEq/L
D) A hemoglobin A1C of 4.8
A
Feedback:
Uric acid excretion is decreased because thiazides interfere with its secretory mechanism. High levels of uric acid can result in a condition called gout. Hydrochlorothiazide does not reduce BUN levels. Thiazide diuretics may lead to hypokalemia and increase blood glucose levels. The potassium and hemoglobin A1C levels are normal and not affected by the medication.
