4. What is the gold standard for verifying initial placement of an NG tube?. Air auscultation. X ray radiography. Patient coughing. pH test alone.

5. A gastric aspirate pH of 3.0 most likely indicates the tube is located in the: Lung. Esophagus. Stomach. Intestine.

6. Air auscultation for NG placement confirmation is considered: Most accurate method. Gold standard. Secondary verification. Least reliable method.

7. During enteral feeding the patient's head of bed should be elevated to: 1015. 2025. 3045. 6090.

8. After a bolus feeding, the nurse should keep the patient elevated for: 10 minutes. 30 minutes. 1 hour. 2 hours.

9. A gastric residual volume greater than 250 mL indicates: Normal digestion. Rapid gastric emptying. Delayed gastric emptying. Tube obstruction.

10. What is the appropriate nursing action if GRV is greater than 250 mL?. Continue feeding. Hold feeding and notify provider. Increase feeding rate. Flush tube with saline.

11. Gastric lavage is MOST appropriate for which scenario?. Bleach ingestion. Petroleum ingestion. Pill overdose within 3 hours. Battery ingestion.

12. Gastric lavage is contraindicated in ingestion of: Sedatives. Acid or alkali substances. Aspirin. Food poisoning.

13. The Sengstaken Blakemore tube is primarily used to treat: Gastric obstruction. Esophageal varices bleeding. Bowel obstruction. Peptic ulcers.

14. Which tube includes a dedicated esophageal suction port?. Levin tube. Minnesota tube. Salem sump tube. Ewald tube.

15. When managing a Sengstaken Blakemore tube, the nurse must keep what at the bedside?. Oxygen mask. Suction catheter. Surgical scissors. Feeding pump.

16. Upward migration of an esophageal tamponade tube can cause: Bradycardia. Airway obstruction. Hypoglycemia. Hypertension.

17. A PEG tube is inserted into which location?. Duodenum. Jejunum. Stomach. Esophagus.

18. A J tube delivers nutrition directly into the: Stomach. Colon. Jejunum. Esophagus.

19. Which feeding tube is preferred when aspiration risk is very high?. G tube. J tube. Levin tube. Salem sump tube.

20. Jackson Pratt drains function using: Gravity drainage. Bulb suction. Electric suction. Osmotic pressure.

21. Hemovac drains are typically used for: Very small drainage. Large volume drainage. No drainage. Air drainage.

22. A Penrose drain functions through: Closed suction. Vacuum pressure. Gravity drainage. Pump suction.

23. A biliary T tube is placed after: Appendectomy. Cholecystectomy. Colon surgery. Gastric bypass.

24. Initial drainage from a biliary T tube in the first 24 hours may reach approximately: 50 mL. 100 mL. 500 mL. 1000 mL.

25. During abdominal assessment the correct order is: Inspect, auscultate, percuss, palpate. Palpate, inspect, auscultate, percuss. Inspect, palpate, auscultate, percuss. Auscultate, inspect, palpate, percuss.

26. Why must auscultation occur before palpation during abdominal assessment?. To improve visualization. To stimulate bowel sounds. To prevent artificially stimulating bowel sounds. To increase patient comfort.

27. If a feeding tube migrates outward by about 2 inches, the nurse should: Push it back in. Continue feeding. Stop feeding and prepare for reinsertion. Flush with saline.

28. Reinserting the guide wire into a partially dislodged tube can cause: Infection. Bleeding. Tissue perforation. Dehydration.

29. During feeding tube care, flushing with approximately how much water is typical?. 5 mL. 10 mL. 30 mL. 100 mL.

30. The purpose of the Salem sump air vent is to: Deliver oxygen. Equalize pressure. Deliver medications. Drain bile.
