A client has hypokalemia. Which question by the nurse obtains the most information on a possible cause?
a. "Do you use sugar substitutes?"
b. "Do you use diuretics or laxatives?"
c. "Do you have any kidney disease?"
d. "Have your bowel habits changed recent-ly?"
B
Misuse and overuse of diuretics, especially high-ceiling (loop) and thiazide diuretics, and laxa-tives are common causes of hypokalemia in older adults and in clients with eating disorders. Sugar substitutes and bowel habits are not related to hypokalemia. The client with kidney disease would be more likely to have hyperkalemia.
