8. A nurse and a registered dietitian are assessing clients for partial parenteral nutrition (PPN). For which client would the nurse suggest another route of providing nutrition? a. Client with congestive heart failure b. Older client with dementia c. Client who has multiorgan failure d. Client who is post gastric resection

ANS: A Clients receiving PPN typically get large amounts of fluid volume, making the client with heart failure a poor candidate. The other candidates are appropriate for this type of nutritional support.

6. A nurse is caring for a client receiving enteral feedings through a Dobhoff tube. What action by the nurse is best to prevent hyperosmolarity? a. Administer free-water boluses. b. Change the clients formula. c. Dilute the clients formula. d. Slow the rate of infusion.

ANS: A Proteins and sugar molecules in the enteral feeding product contribute to dehydration due to increased osmolarity. The nurse can administer free-water boluses after consulting with the provider on the appropriate amount and timing of the boluses, or per protocol. The client may not be able to switch formulas. Diluting the formula is not appropriate. Slowing the rate of the infusion will not address the problem.

9. A client is receiving total parenteral nutrition (TPN). On assessment, the nurse notes the clients pulse is 128 beats/min, blood pressure is 98/56 mm Hg, and skin turgor is dry. What action should the nurse perform next? a. Assess the 24-hour fluid balance. b. Assess the clients oral cavity. c. Prepare to hang a normal saline bolus. d. Turn up the infusion rate of the TPN.

ANS: A This client has clinical indicators of dehydration, so the nurse calculates the clients 24-hour intake, output, and fluid balance. This information is then reported to the provider. The clients oral cavity assessment may or may not be consistent with dehydration. The nurse may need to give the client a fluid bolus, but not as an independent action. The clients dehydration is most likely due to fluid shifts from the TPN, so turning up the infusion rate would make the problem worse, and is not done as an independent action.

5. When working with older adults to promote good nutrition, what actions by the nurse are most appropriate? (Select all that apply.) a. Allow uninterrupted time for eating. b. Assess dentures for appropriate fit. c. Ensure the client has glasses on when eating. d. Provide salty foods that the client can taste. e. Serve high-calorie, high-protein snacks.

ANS: A, B, C, E Older adults need unhurried and uninterrupted time for eating. Dentures should fit appropriately and glasses, if used, should be on. High-calorie, high-protein snacks are a good choice. Salty snacks are not recommended because all adults should limit sodium in their diets.

4. A client is receiving bolus feedings through a Dobhoff tube. What action by the nurse is most important? a. Auscultate lung sounds after each feeding. b. Check tube placement before each feeding. c. Check tube placement every 8 hours.d. Weigh the client daily on the same scale.

ANS: B For bolus feedings, the nurse checks placement of the tube per institutional policy prior to each feeding, which is more often than every 8 hours during the day. Auscultating lung sounds is also important, but this will indicate a complication that has already occurred. Weighing the client is important to determine if nutritional goals are being met.

4. A clients small-bore feeding tube has become occluded after the nurse administered medications. What actions by the nurse are best? (Select all that apply.) a. Attempt to dissolve the clog by instilling a cola product. b. Determine if any of the medications come in liquid form. c. Flush the tube before and after administering medications. d. Mix all medications in the formula and use a feeding pump. e. Try to flush the tube with 30 mL of water and gentle pressu

ANS: B, C, E If the tube is obstructed, use a 50-mL syringe and gentle pressure to attempt to open the tube. Cola products should not be used unless water is not effective. To prevent future problems, determine if any of the medications can be dispensed in liquid form and flush the tube with water before and after medication administration. Do not mix medications with the formula

5. A client having a tube feeding begins vomiting. What action by the nurse is most appropriate? a. Administer an antiemetic. b. Check the clients gastric residual. c. Hold the feeding until the nausea subsides. d. Reduce the rate of the tube feeding by half.

ANS: C The nurse should hold the feeding until the nausea and vomiting have subsided and consult with the provider on the rate at which to restart the feeding. Giving an antiemetic is not appropriate. After vomiting, a gastric residual will not be accurate. The nurse should not continue to feed the client while he or she is vomiting.

7. A nurse is caring for four clients receiving enteral tube feedings. Which client should the nurse see first? a. Client with a blood glucose level of 138 mg/dL b. Client with foul-smelling diarrhea c. Client with a potassium level of 2.6 mEq/L d. Client with a sodium level of 138 mEq/L

ANS: C The potassium is critically low, perhaps due to hyperglycemia-induced hyperosmolarity. The nurse should see this client first. The blood glucose reading is high, but not extreme. The sodium is normal. The client with the diarrhea should be seen last to avoid cross-contamination.

20. A client is receiving total parenteral nutrition (TPN). What action by the nurse is most important? a. Assessing blood glucose as directed b. Changing the IV dressing each day c. Checking the TPN with another nurse d. Performing appropriate hand hygiene

ANS: D Clients on TPN are at high risk for infection. The nurse performs appropriate hand hygiene as a priority intervention. Checking blood glucose is also an important measure, but preventing infection takes priority. The IV dressing is changed every 48 to 72 hours. TPN does not need to be double-checked with another nurse.
