HESI RN
Nutrition HESI Practice Exam
1. The nurse is reviewing laboratory results on a client with acute renal failure. Which one of the following should be reported immediately?
- A. Blood urea nitrogen 50 mg/dl
- B. Hemoglobin of 10.3 g/dl
- C. Venous blood pH 7.30
- D. Serum potassium 6 mEq/L
Correct answer: D
Rationale: A serum potassium level of 6 mEq/L indicates hyperkalemia, which can be life-threatening and requires immediate intervention. Hyperkalemia can lead to dangerous cardiac arrhythmias and must be addressed promptly. The other options are not as urgent. A blood urea nitrogen level of 50 mg/dl may indicate kidney dysfunction but does not require immediate intervention. Hemoglobin of 10.3 g/dl may suggest anemia, which needs management but is not an immediate threat. A venous blood pH of 7.30 may indicate acidosis, which is concerning but not as acutely dangerous as hyperkalemia.
2. A 14-year-old with a history of sickle cell disease is admitted to the hospital with a diagnosis of vaso-occlusive crisis. Which statement by the client would be most indicative of the etiology of this crisis?
- A. I knew this would happen. I've been eating too much red meat lately.
- B. I really enjoyed my fishing trip yesterday. I caught 2 fish.
- C. I have really been working hard practicing with the debate team at school.
- D. I went to the healthcare provider last week for a cold, and I have gotten worse.
Correct answer: D
Rationale: The correct answer is D because a recent illness, such as a cold, can trigger a vaso-occlusive crisis in sickle cell disease. This crisis is often precipitated by infections or other illnesses that cause a systemic inflammatory response, leading to vaso-occlusion. Choices A, B, and C do not directly relate to the etiology of a vaso-occlusive crisis in sickle cell disease, making them incorrect.
3. 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.
4. A client has returned from a cardiac catheterization. Which one of the following assessments would indicate the client is experiencing a complication from the procedure?
- A. Increased blood pressure
- B. Increased heart rate
- C. Loss of pulse in the extremity
- D. Decreased urine output
Correct answer: C
Rationale: Loss of pulse in the extremity can indicate an arterial blockage, requiring immediate medical evaluation. Increased blood pressure and heart rate are common physiological responses after cardiac catheterization and may not necessarily indicate a complication. Decreased urine output is more indicative of renal function and may not be directly related to complications from the procedure.
5. During a physical assessment on a client who just had an endotracheal tube inserted, which finding would call for immediate action by the nurse?
- A. Breath sounds are auscultated bilaterally
- B. Mist is visible in the T-Piece
- C. Pulse oximetry of 88%
- D. Client is unable to speak
Correct answer: C
Rationale: A pulse oximetry reading of 88% indicates hypoxemia, which requires immediate intervention to ensure adequate oxygenation. In this scenario, the priority is to address the low oxygen saturation to prevent further complications. Auscultation of bilateral breath sounds is a positive finding as it indicates air entry into both lungs. Mist in the T-piece is expected in clients with an endotracheal tube, and the inability to speak is common due to the tube's placement.
