Answer to Question 1

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.

Answer to Question 2

A
Feedback:
Caution should be used with the following conditions, which include systemic lupus erythematosus (SLE), which frequently causes glomerular changes and renal dysfunction that could precipitate renal failure in some cases; glucose tolerance abnormalities or diabetes mellitus, which is worsened by the glucose-elevating effects of many diuretics; and gout, which reflects an abnormality in normal tubule reabsorption and secretion. There would be no reason to check ketones four times daily or to have a creatinine clearance once a month.
