Question 1
Regular
A patient is receiving TPN via a central venous catheter. The patient's wife is concerned about his care and wants to know why the TPN bag is not changed as often as a regular IV bag of solution would be. You respond by telling her the standard for changing the TPN bag is every:
Correct!
Incorrect
The correct answer is: D
Rationale
Every 24 hours. TPN, or total parenteral nutrition, is designed for longer infusion periods to maintain nutritional balance, which allows for a less frequent change compared to standard IV solutions.
A: 6 hours. Frequent changes every 6 hours would lead to unnecessary interruptions in nutrition delivery and could increase the risk of infection through repeated access to the catheter.
B: 8 hours. Changing TPN every 8 hours would not align with the stability of the solution and could compromise the patient’s nutritional intake, which is critical for their recovery.
C: 12 hours. A 12-hour change interval would be inefficient, as TPN is formulated for extended use, making longer intervals more suitable for maintaining nutrient integrity and minimizing infection risk.

Question 2
Regular
You are caring for a patient who is scheduled for surgery. Your teaching will include information about nutrition and healing. You will tell the patient which of the following macronutrients is required for tissue repair?
Correct!
Incorrect
The correct answer is: D
Rationale
D: Protein is essential for tissue repair as it provides the building blocks necessary for the synthesis of new cells and tissues. Adequate protein intake supports recovery and healing after surgery, ensuring optimal recovery outcomes.
A: Carbohydrates primarily serve as an energy source and do not contribute directly to tissue repair processes, which require specific nutrients for healing.
B: Fat plays a role in energy storage and hormone production but lacks the direct involvement in tissue regeneration that protein offers, making it less critical for healing.
C: Vitamin E is an antioxidant that helps protect cells from damage but does not directly aid in the repair of tissues, unlike protein, which is vital for recovery.
E: Vitamin K is important for blood clotting and bone health, yet it does not participate directly in the tissue repair mechanism essential after surgical procedures.

Question 3
Regular
As a home health nurse, you will be caring for the patients noted below. Which patient is at greatest risk for experiencing inadequate nutrition?
Correct!
Incorrect
The correct answer is: B
Rationale
B: A 72-year-old widow who had a mild CVA 3 days ago. This patient is at the highest risk for inadequate nutrition due to potential swallowing difficulties, decreased appetite, and social isolation following the stroke, which complicates meal preparation and consumption.
A: A 60-year-old white male recently diagnosed with type 2 diabetes. While this patient has a new diagnosis, diabetes management often includes dietary education and support, mitigating immediate nutrition risks.
C: A 25-year-old mother with two preschoolers who is recovering from a tonsillectomy. Although she may experience temporary swallowing challenges, her age and support system typically ensure adequate nutrition during recovery.
D: A 55-year-old black male recovering at home following coronary artery bypass surgery. Recovery from surgery involves dietary modifications, but this patient's focus on heart health often leads to improved nutrition awareness and adherence.

Question 4
Regular
Critically ill, tube-fed patients should have the head of the bed raised to during feedings and for up to 1 hour after feedings.
Correct!
Incorrect
The correct answer is: C
Rationale
Patients who are critically ill and tube-fed should have the head of the bed raised to 30 to 45 degrees during feedings and for up to 1 hour after feedings.
This position helps to prevent aspiration and promotes better digestion by allowing gravity to assist in the movement of food through the gastrointestinal tract. It is essential for patient safety and comfort.
A: 5 to 10 degrees This angle is insufficient for preventing aspiration and does not adequately support digestion, posing a risk for critically ill patients during and after feedings.
B: 15 to 25 degrees This elevation does not provide the necessary support for aspiration prevention or effective digestion, leaving patients vulnerable during tube feedings and their aftermath.
D: 50 to 60 degrees This angle may be excessively steep, potentially causing discomfort or complications for patients, thus negating the benefits of a more moderate position during tube feedings.
E: 90 degrees Sitting completely upright can be uncomfortable and impractical for critically ill patients, making it an inappropriate choice for safe tube feeding practices and patient care.

Question 5
Multiple Choice
What intervention(s) should you prepare for when caring for a patient who is 6 hours post burn with 30% seconddegree burns and absent bowel sounds?
Correct!
Incorrect
The correct answer is: A,B
Rationale
Withholding oral intake. This intervention is crucial for a patient with significant burns and absent bowel sounds, as it prevents further gastrointestinal complications and allows the body to stabilize and heal.
C: Starting a diet of clear liquids only. Introducing any oral intake could exacerbate gastrointestinal distress and is contraindicated with absent bowel sounds, indicating potential ileus or other complications.
D: Inserting a feeding tube for nutrition. This approach is inappropriate given the patient's absent bowel sounds, as it could lead to aspiration or further gastrointestinal disruption in an unstable state.
E: Feeding the patient a soft diet. Offering a soft diet disregards the critical need for bowel rest due to absent sounds, risking complications and impeding the healing process after significant burns.

Question 6
Drag and Drop
Which actions are taken to verify the correct placement of a small-bore NG tube immediately after insertion? (Rank your answers in the correct order.)
Drag and drop to arrange in correct order:
A.
Aspirate the gastric contents, check the pH of contents, and observe the color
B.
Confirm the size of the feeding tube after taping
C.
Place the distal end of the tube in a glass of water and observe for bubbles indicating air exchange
D.
Take an x-ray
E.
Flush the tube with 15 to 30 mL of water to ensure its correct placement
Correct!
Incorrect
The correct answer is: D,A,B,E,C
Rationale
Taking an x-ray is the most definitive action to verify the correct placement of a small-bore NG tube immediately after insertion. X-rays provide clear visualization of the tube's location in relation to the stomach, ensuring accurate placement before any feeding or medication administration occurs, thus preventing complications.
B: Confirm the size of the feeding tube after taping. This does not assess tube placement; it merely relates to the tube's dimensions, which doesn't guarantee it is correctly positioned.
E: Flush the tube with 15 to 30 mL of water to ensure its correct placement. Flushing does not confirm placement; it only tests patency, failing to verify the tube's position in the stomach.
C: Place the distal end of the tube in a glass of water and observe for bubbles indicating air exchange. This method lacks reliability and does not provide a clear indication of the tube's accurate placement within the gastrointestinal tract.

Question 7
Multiple Choice
You are working in a pediatric clinic when the mother of a 15-year-old female patient calls with concerns about her daughter. Which behaviors she describes would alert you to a possible eating disorder?
Correct!
Incorrect
The correct answer is: A,C,D
Rationale
A, C, D: She constantly worries about her weight, exercises 2 to 3 hours daily, and often complains of a sore throat and indigestion, all of which are indicators of potential eating disorders. These behaviors reflect unhealthy preoccupations with body image and physical health, which are significant red flags for disordered eating patterns in adolescents.
B: She talks about various foods and their nutritional quality. Discussing nutrition can indicate a healthy interest in eating, rather than an obsession or disorder, which is not inherently alarming.
E: She talks frequently with friends about school activities. Engaging in social interactions about school activities suggests normal adolescent behavior, and does not indicate any concerns related to eating disorders or body image issues.
