Correct Answer: B

Rationale: Water-soluble lubricant is used to lubricate 3 to 4 inches of the tube at the insertion end. An oil lubricant is not used because if the tube accidentally goes into the bronchus, pneumonia can develop. Half-inch tape is used to secure the tube after the correct placement is verified. A 50-mL catheter tip syringe is used to aspirate gastric contents to confirm placement. The client will be asked to take a sip of water through a straw to help with the passage of the tube.

Correct Answer: A

Rationale: Following this procedure, the nurse monitors the client's vital signs closely for indications of hemorrhage and observes the needle insertion site for bleeding and bile leakage. A sandbag is placed over the insertion site to prevent bleeding. The client is maintained on bedrest, and oral intake is avoided in the immediate postprocedure period in case surgery is necessary to control hemorrhage of bile extravasation.

Correct Answer: A

Rationale: Administering pain medication would have the highest priority during the first hour after the client's admission. Pain relief is essential to address the client's immediate discomfort and distress. Completing the admission history, maintaining hydration, and teaching about planned diagnostic tests are important aspects of care but can be addressed after addressing the client's pain and stabilizing their condition.

Correct Answer: A

Rationale: The initial way to determine if a nasogastric tube is in the stomach is to apply suction to the tube with a syringe and observe for the return of stomach contents. Then the pH of the aspirate can be measured. This is the method of choice. One would not irrigate until tube placement is confirmed. Observing for air bubbles when the free end of the tube is placed under water is an unacceptable, unsafe method of determining tube placement. Another method is to instill air into the tube with a syringe while auscultating over the epigastric area. Hearing the air enter the stomach helps ensure proper placement, but the method is not foolproof and is no longer considered an effective or preferred way to determine placement.

Correct Answer: C

Rationale: Peripheral tissue perfusion is a major concern in the postoperative period following an abdominal aneurysm repair. Peripheral pulses should be checked frequently during the first 24 hours. A weak or absent pulse may be a sign of embolization or graft closure, especially if accompanied by a pale, cold, mottled extremity; the nurse should immediately report this to the surgeon. Risk for infection, deficient knowledge, and activity intolerance are all important nursing diagnoses in the postoperative period, but peripheral tissue perfusion is the most immediate concern.
