During patient education, the nurse discusses the major side effects of thiazide diuretics, because the patient has just begun therapy. The nurse should review the laboratory results for the patient and should be concerned about a finding of a
a. blood sugar level of 80.
b. potassium level of 3.
c. blood pressure of 106/48.
d. potassium level of 5.7.
ANS: B
The nurse should be concerned if the potassium level is low (3), because thiazide diuretics are potassium wasting and will exacerbate any hypokalemia.
A blood sugar level of 80 is normal, and a thiazide diuretic may possibly elevate blood glucose.
A blood pressure of 106/48 may be significant; however, it is not a laboratory value.
A potassium level of 5.7 is high; however the thiazide diuretic should be given to reduce the potassium level.
