HESI RN
HESI Nutrition Practice Exam
1. A nurse checks a client who is on a volume-cycled ventilator. Which finding indicates that the client may need suctioning?
- A. drowsiness
- B. complaint of nausea
- C. pulse rate of 92
- D. restlessness
Correct answer: D
Rationale: Restlessness is often a sign of respiratory distress or secretion build-up, indicating the need for suctioning. While drowsiness (choice A) can be a sign of hypoxia, it is not as immediate an indication for suctioning as restlessness. Complaint of nausea (choice B) and a pulse rate of 92 (choice C) are not directly related to the need for suctioning in a client on a volume-cycled ventilator.
2. The client with chronic renal failure is receiving peritoneal dialysis. Which of the following is the most important action for the nurse to take?
- A. Administer the prescribed antibiotics.
- B. Monitor for signs of infection.
- C. Encourage the client to increase fluid intake.
- D. Monitor the client's weight daily.
Correct answer: B
Rationale: Monitoring for signs of infection is crucial in clients undergoing peritoneal dialysis. Peritonitis is a severe complication associated with peritoneal dialysis, making it essential to promptly identify any signs of infection, such as abdominal pain, cloudy dialysate, fever, and an elevated white blood cell count. Administering antibiotics without proper assessment can lead to antibiotic resistance and should not be the initial action. Encouraging increased fluid intake may not be appropriate without assessing the client's fluid status. Monitoring weight alone does not address the immediate risk of peritonitis in a client undergoing peritoneal dialysis.
3. The nurse is caring for a preterm newborn with nasal flaring, grunting, and sternal retractions. After administering surfactant, which assessment is most important for the nurse to monitor?
- A. Bowel sounds
- B. Heart rate
- C. Arterial blood gases
- D. Apnea episodes
Correct answer: C
Rationale: Corrected Rationale: Surfactant therapy is used to improve lung function and gas exchange in premature infants with respiratory distress. Monitoring arterial blood gases is essential to assess the effectiveness of the treatment and ensure adequate oxygenation. While monitoring heart rate is important in neonatal care, assessing arterial blood gases will provide direct information regarding the infant's oxygenation status post-surfactant administration. Bowel sounds are not directly related to the respiratory distress symptoms described, and monitoring apnea episodes, although important in preterm infants, is not the most crucial assessment immediately following surfactant administration.
4. The nurse is reinforcing home care instructions with a client who is being discharged following a transurethral resection of the prostate (TURP). Which intervention is most important for the nurse to include in the client teaching?
- A. Avoid strenuous activity for 6 weeks.
- B. Report fresh blood in the urine.
- C. Take acetaminophen for a fever over 101°F.
- D. Consume 6 to 8 glasses of water daily.
Correct answer: B
Rationale: Reporting fresh blood in the urine is crucial as it may indicate postoperative complications requiring immediate attention. This symptom can be a sign of bleeding, infection, or other issues that need prompt medical evaluation. Avoiding strenuous activity for 6 weeks is important but not as urgent as reporting fresh blood. Taking acetaminophen for a fever over 101°F is relevant but addressing fresh blood in the urine takes precedence. Consuming an adequate amount of water daily is beneficial but not as critical as recognizing and reporting signs of potential complications.
5. Prophase is the first stage of mitosis. Which of the following best describes chromosomes during this stage?
- A. They are gathered on either side of the separating cell
- B. They are all aligned along the metaphase plate
- C. They are attached to the spindle
- D. They are visibly separate
Correct answer: D
Rationale: The correct answer is D. During prophase, the chromosomes condense and become visible as distinct structures under a microscope. Choice A is incorrect as chromosomes are not gathered on either side of the separating cell during prophase. Choice B is incorrect because chromosomes align along the metaphase plate during the subsequent stage, metaphase. Choice C is incorrect as chromosomes become attached to the spindle fibers during prometaphase, the stage following prophase.
