Answer to Question 1

ANS: D
The patient who is vomiting will be unable to tolerate enteral nutrition. Enteral feedings require a functioning gastrointestinal tract. TPN is more costly and does not carry significant benefits when compared with risks, so it should only be used when enteral nutrition cannot be used.

Answer to Question 2

ANS: A
The nurse should determine gastric residual before each feeding when patients are receiving intermittent feedings. A residual greater than 50 of a previous feeding indicates delayed gastric emptying and warrants notifying the provider. This patient has a residual less than 50, so the nurse may proceed with the next feeding. A residual of 50 mL is significant in patients receiving continuous enteral feedings. The nurse cannot change the rate of an enteral infusion without an order from the provider.
