Sample Questions

 

1. A nurse is preparing to place a patient’s ordered nasogastric tube. How should the nurse best determine the correct length of the nasogastric tube?

  1. A)  Place distal tip to nose, then ear tip and end of xiphoid process.
  2. B)  Instruct the patient to lie prone and measure tip of nose to umbilical area.
  3. C)  Insert the tube into the patient’s nose until secretions can be aspirated.
  4. D)  Obtain an order from the physician for the length of tube to insert.

Ans: A

Feedback:

Tube length is traditionally determined by (1) measuring the distance from the tip of the nose to the earlobe and from the earlobe to the xiphoid process, and (2) adding up to 6 inches for NG placement or at least 8 to 10 inches or more for intestinal placement, although studies do not necessarily confirm that this is a reliable technique. The physician would not prescribe a specific length and the umbilicus is not a landmark for this process. Length is not determined by aspirating from the tube.

2. A patient is concerned about leakage of gastric contents out of the gastric sump tube the nurse has just inserted. What would the nurse do to prevent reflux gastric contents from coming through the blue vent of a gastric sump tube?

  1. A)  Prime the tubing with 20 mL of normal saline.
  2. B)  Keep the vent lumen above the patient’s waist.
  3. C)  Maintain the patient in a high Fowler’s position.
  4. D)  Have the patient pin the tube to the thigh.

Ans: B

Feedback:

The blue vent lumen should be kept above the patient’s waist to prevent reflux of gastric contents through it; otherwise it acts as a siphon. A one-way anti-reflux valve seated in the blue pigtail can prevent the reflux of gastric contents out the vent lumen. To prevent reflux, the nurse does not prime the tubing, maintain the patient in a high Fowler’s position, or have the patient pin the tube to the thigh.

3. A patient receiving tube feedings is experiencing diarrhea. The nurse and the physician suspect that the patient is experiencing dumping syndrome. What intervention is most appropriate?

  1. A)  Stop the tube feed and aspirate stomach contents.
  2. B)  Increase the hourly feed rate so it finishes earlier.
  3. C)  Dilute the concentration of the feeding solution.
  4. D)  Administer fluid replacement by IV.

Ans: C

Feedback:

Dumping syndrome can generally be alleviated by starting with a dilute solution and then increasing the concentration of the solution over several days. Fluid replacement may be necessary but does not prevent or treat dumping syndrome. There is no need to aspirate stomach contents. Increasing the rate will exacerbate the problem.

4. A nurse is admitting a patient to the postsurgical unit following a gastrostomy. When planning assessments, the nurse should be aware of what potential postoperative complication of a gastrostomy?

  1. A)  Premature removal of the G tube
  2. B)  Bowel perforation
  3. C)  Constipation
  4. D)  Development of peptic ulcer disease (PUD)

Ans: A

Feedback:

A significant postoperative complication of a gastrostomy is premature removal of the G tube. Constipation is a less immediate threat and bowel perforation and PUD are not noted to be likely complications.

5. A nursing educator is reviewing the care of patients with feeding tubes and endotracheal tubes (ET). The educator has emphasized the need to check for tube placement in the stomach as well as residual volume. What is the main purpose of this nursing action?

  1. A)  Prevent gastric ulcers
  2. B)  Prevent aspiration
  3. C)  Prevent abdominal distention
  4. D)  Prevent diarrhea

Ans: B

Feedback:

Protecting the client from aspirating is essential because aspiration can cause pneumonia, a potentially life-threatening disorder. Gastric ulcers are not a common complication of tube feeding in clients with ET tubes. Abdominal distention and diarrhea can both be associated with tube feeding, but prevention of these problems is not the primary rationale for confirming placement.

6. The nurse is administering total parenteral nutrition (TPN) to a client who underwent surgery for gastric cancer. Which of the nurse’s assessments most directly addresses a major complication of TPN?

  1. A)  Checking the patient’s capillary blood glucose levels regularly
  2. B)  Having the patient frequently rate his or her hunger on a 10-point scale
  3. C)  Measuring the patient’s heart rhythm at least every 6 hours
  4. D)  Monitoring the patient’s level of consciousness each shift

Ans: A

Feedback:

The solution, used as a base for most TPN, consists of a high dextrose concentration and may raise blood glucose levels significantly, resulting in hyperglycemia. This is a more salient threat than hunger, though this should be addressed. Dysrhythmias and decreased LOC are not among the most common complications.
