Answer to Question 1

D
The nurse should explain to the patient the importance of rectally expelling all barium. Large amounts of fluids should be taken to prevent constipation.

Answer to Question 2

D
Feedback:
An increase in the renal threshold for glucose, as often occurs in older adults, is a serious concern. False-negative results in diabetic urine testing can occur for this reason.
