Answer to Question 1

C
Feedback:
Sodium polystyrene sulfonate (Kayexalate), a cation exchange resin, administered orally, removes potassium from the body in the stool. Kayexalate does not decrease the absorption of potassium. Kayexalate does not increase urinary excretion of potassium. Kayexalate does not release sodium to acidify urine with potassium.

Answer to Question 2

B
Feedback:
It is essential to discontinue metformin if renal impairment occurs. The other listed changes in laboratory values do not necessarily indicate that metformin should be discontinued.
