Nokea
A patient has been brought to the emergency department by EMS after telling a family member that he deliberately took an overdose of NSAIDs a few minutes earlier. If lavage is ordered, the nurse should prepare to assist with the insertion of what type of tube?
- A. Nasogastric tube
- B. Levin tube
- C. Gastric sump
- D. Orogastric tube
Correct Answer: D
Rationale: An orogastric tube is a large-bore tube inserted through the mouth with a wide outlet for removal of gastric contents; it is used primarily in the emergency department or an intensive care setting. Nasogastric, Levin, and gastric sump tubes are not used for this specific purpose.

A nurse is initiating parenteral nutrition (PN) to a postoperative patient who has developed complications. The nurse should initiate therapy by performing which of the following actions?
- A. Starting with a rapid infusion rate to meet the patients nutritional needs as quickly as possible
- B. Initiating the infusion slowly and monitoring the patients fluid and glucose tolerance
- C. Changing the rate of administration every 2 hours based on serum electrolyte values
- D. Increasing the rate of infusion at mealtimes to mimic the circadian rhythm of the body
Correct Answer: B
Rationale: PN solutions are initiated slowly and advanced gradually each day to the desired rate as the patients fluid and glucose tolerance permits. The formulation of the PN solutions is calculated carefully each day to meet the complete nutritional needs of the individual patient based on clinical findings and laboratory data. It is not infused more quickly at mealtimes.
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?
- A. Stop the tube feed and aspirate stomach contents.
- B. Increase the hourly feed rate so it finishes earlier.
- C. Dilute the concentration of the feeding solution.
- D. Administer fluid replacement by IV.
Correct Answer: C
Rationale: 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.
A nurse is creating a care plan for a patient who is receiving parenteral nutrition. The patients care plan should include nursing actions relevant to what potential complications? Select all that apply.
- A. Dumping syndrome
- B. Clotted or displaced catheter
- C. Pneumothorax
- D. Hyperglycemia
- E. Line sepsis
Correct Answer: B,C,D,E
Rationale: Common complications of PN include a clotted or displaced catheter, pneumothorax, hyperglycemia, and infection from the venous access device (line sepsis). Dumping syndrome applies to enteral nutrition, not PN.
A patient has a gastrostomy tube that has been placed to drain stomach contents by low intermittent suction. What is the nurses priority during this aspect of the patients care?
- A. Measure and record drainage.
- B. Monitor drainage for change in color.
- C. Titrate the suction every hour.
- D. Feed the patient via the G tube as ordered.
Correct Answer: A
Rationale: This drainage should be measured and recorded because it is a significant indicator of GI function. The nurse should indeed monitor the color of the output, but fluid balance is normally the priority. Frequent titration of the suction should not be necessary and feeding is contraindicated if the G tube is in place for drainage.
A critical care nurse is caring for a patient diagnosed with acute pancreatitis. The nurse knows that the indications for starting parenteral nutrition (PN) for this patient are what?
- A. 5% deficit in body weight compared to preillness weight and increased caloric need
- B. Calorie deficit and muscle wasting combined with low electrolyte levels
- C. Inability to take in adequate oral food or fluids within 7 days
- D. Significant risk of aspiration coupled with decreased level of consciousness
Correct Answer: C
Rationale: The indications for PN include an inability to ingest adequate oral food or fluids within 7 days. Weight loss, muscle wasting combined with electrolyte imbalances, and aspiration indicate a need for nutritional support, but this does not necessarily have to be parenteral.
