HESI Nutrition Practice Exam
1. A client is receiving total parenteral nutrition (TPN). Which of these interventions should the nurse perform to reduce the risk of infection?
- A. Changing the TPN tubing and solution every 24 hours
- B. Monitoring the TPN infusion rate closely
- C. Keeping the head of the bed elevated
- D. Ensuring the solution is at room temperature before infusing
Correct answer: A
Rationale: The correct answer is to change the TPN tubing and solution every 24 hours to reduce the risk of infection. This practice helps prevent microbial growth and contamination in the TPN solution. Monitoring the infusion rate closely (choice B) is important for preventing metabolic complications but does not directly reduce the risk of infection. Keeping the head of the bed elevated (choice C) is beneficial for preventing aspiration in feeding tube placement but is unrelated to reducing infection risk in TPN. Ensuring the solution is at room temperature before infusing (choice D) is essential for patient comfort and preventing metabolic complications but does not specifically address infection risk reduction.
2. A client with diabetes is being educated about the dietary source that should provide the greatest percentage of their calories. Which of the following statements by the client indicates an understanding of the teaching?
- A. Most of my calories each day should be from fats.
- B. I should eat more calories from complex carbohydrates than anything else.
- C. Simple sugars are needed more than other calorie sources.
- D. Protein should be my main source of calories.
Correct answer: B
Rationale: The correct answer is B. In diabetes management, complex carbohydrates should constitute the largest portion of the diet as they help in maintaining steady energy levels and managing blood sugar. Choice A is incorrect because a high-fat diet can lead to complications in diabetes. Choice C is incorrect as simple sugars can cause rapid spikes in blood sugar levels. Choice D is incorrect as protein, while important, should not be the main source of calories for a diabetic individual.
3. In a client with chronic kidney disease having a serum potassium level of 6.5 mEq/L, which assessment is the most critical for the nurse to perform?
- A. Neurological status
- B. Cardiac status
- C. Respiratory status
- D. Gastrointestinal status
Correct answer: B
Rationale: Corrected Rationale: Assessing cardiac status is crucial in hyperkalemia as high potassium levels can result in life-threatening arrhythmias. Monitoring the heart rhythm and ECG findings is essential to prevent cardiac complications. Neurological status, respiratory status, and gastrointestinal status are important assessments too, but in the context of hyperkalemia, cardiac status takes precedence due to the immediate risk of cardiac arrhythmias.
4. A client has a history of chronic obstructive pulmonary disease (COPD). As the nurse enters the client's room, the oxygen is running at 6 liters per minute, the client's color is flushed, and his respirations are 8 per minute. What should the nurse do first?
- A. Obtain a 12-lead EKG
- B. Place the client in high Fowler's position
- C. Lower the oxygen rate
- D. Take baseline vital signs
Correct answer: C
Rationale: In a client with COPD, it is crucial to prevent carbon dioxide retention by avoiding high oxygen levels. As the client's oxygen is running at 6 liters per minute and he is showing signs of oxygen toxicity, such as flushed color and low respirations, the nurse's priority should be to lower the oxygen rate. This action helps prevent worsening the client's condition. Obtaining an EKG, placing the client in high Fowler's position, or taking baseline vital signs are important assessments but addressing the potential oxygen toxicity takes precedence in this scenario.
5. When assessing a client for signs and symptoms of a fluid volume deficit, the nurse would be most concerned with which finding?
- A. Blood pressure of 90/60 mm Hg
- B. Heart rate of 110 beats per minute
- C. Respiratory rate of 24 breaths per minute
- D. Urine output of 30 mL per hour
Correct answer: A
Rationale: Corrected Rationale: A low blood pressure of 90/60 mm Hg is a significant finding indicating fluid volume deficit. In fluid volume deficit, the body tries to compensate by increasing heart rate (choice B) to maintain cardiac output. Respiratory rate (choice C) may increase as a compensatory mechanism, but it is not the primary concern in fluid volume deficit. Urine output (choice D) may decrease in response to fluid volume deficit, but it is a late sign and not the most concerning finding.
