Answer to Question 1

Correct Answer: 4
Rationale: Elevated creatine phosphokinase (CPK) levels could indicate myopathy; if this is suspected, hold the drug and notify the physician. The physician must be notified when myopathy is suspected, so the nurse would not hold the drug and obtain another creatine phosphokinase (CPK) level. If myopathy is suspected, the drug must be held, not administered, and the physician notified. The nurse should not administer the drug, the physician must be notified.

Answer to Question 2

Correct Answer: 2
Rationale: Assessment of bowel sounds is a priority because cholestryamine (Questran) could cause obstruction of the intestines. Cholestryamine (Questran) does not affect cardiac status. Cholestryamine (Questran) does not cause peripheral edema. Cholestryamine (Questran) does not cause rhabdomyolysis, so the nurse would not assess for 24-hour urine output.
