Answer to Question 1
Correct Answer: 1,3,5
The nurse should check the expiration date because the solution is high in sugar, providing an ideal location for pathogen growth. Outdated solutions should never be administered. The primary care provider's order should be checked against the contents of the solution with another nurse to ensure the proper mixture is prepared and administered. A timing tape should be applied to the solution to ensure that the fluid is infused at the proper rate, because it is high in glucose and could induce hyperglycemia if infused too quickly. There is no need to create a sterile field until the fluid is checked for accuracy and the bag prepared. Nurses do not add medications or anything to the prepared TPN, because it must be mixed under sterile technique with a laminar air flow device to prevent introduction of pathogens.
Answer to Question 2
Correct Answer: 3
The most accurate means of assessing placement prior to the first tube feeding is obtaining an x-ray, because this ensures exact location of the tube. Checking pH of stomach contents is the most cost-effective means of assessing placement, and minimizes the client's exposure to radiation. Infusing air and auscultating are not an accurate means of checking placement, because a tube that is high in the esophagus will still sound as though it is properly placed. Checking for residual is also a useful means of assessing placement, but not as accurate as an x-ray.
