During patient education, a nurse is discussing the major side effects of thiazide diuretics with a patient who has just begun therapy
The nurse should review the laboratory findings and should be concerned about administering the diuretic if which finding is present? a. Serum glucose of 80 mg/dL
b. Serum potassium of 3 mEq/L
c. Serum sodium of 147 mg/dL
d. Serum potassium of 4.6 mEq/L
B
The nurse should be concerned if the serum potassium level is low, because thiazide diuretics are partially potassium wasting and may exacerbate the hypokalemia.
A serum glucose of 80 mg/dL is normal, and although thiazide diuretics may increase the blood glucose level, this is not a priority at this time.
A serum sodium level of 147 mg/dL is normal and would not be influenced by thiazide diuretics.
A serum potassium level of 4.6 mEq/L is within normal limits and should be monitored in a pa-tient taking thiazide diuretics, but it is not a concern at this time.
