HESI RN
HESI Nutrition Practice Exam
1. A client is scheduled for a colonoscopy. Which of these instructions should the nurse provide?
- A. You should avoid eating or drinking anything after midnight the day before the test.
- B. You may have a light breakfast the morning of the test.
- C. You will need to drink a bowel preparation solution the day before the test.
- D. You will need to avoid taking any medications the day before the test.
Correct answer: C
Rationale: The correct answer is C: 'You will need to drink a bowel preparation solution the day before the test.' Before a colonoscopy, it is essential to cleanse the colon thoroughly by drinking a bowel preparation solution. This helps to ensure that the colon is clear for the procedure, allowing for better visualization and examination of the colon. Choices A, B, and D are incorrect because avoiding eating or drinking after midnight, having a light breakfast, and avoiding medications are not specific instructions related to the colonoscopy preparation process.
2. To prevent unnecessary hypoxia during suctioning of a tracheostomy, what must the nurse do?
- A. Apply suction for no more than 10 seconds
- B. Maintain a sterile technique
- C. Lubricate 3 to 4 inches of the catheter tip
- D. Withdraw the catheter in a circular motion
Correct answer: A
Rationale: To prevent unnecessary hypoxia during suctioning of a tracheostomy, the nurse must apply suction for no more than 10 seconds. Prolonged suctioning can lead to hypoxia by removing too much oxygen from the patient. Maintaining a sterile technique (choice B) is important to prevent infection but does not directly relate to preventing hypoxia. Lubricating the catheter tip (choice C) helps with the insertion process but does not specifically address hypoxia prevention. Withdrawing the catheter in a circular motion (choice D) is not a standard practice during tracheostomy suctioning and does not contribute to preventing hypoxia.
3. A healthcare provider is collecting data from a client who is receiving chemotherapy and is showing manifestations of malnutrition. Which of the following indicates a Vitamin C deficiency?
- A. Dry, red conjunctiva
- B. Swollen, bleeding gums
- C. Inflammation of the tongue
- D. Pale, brittle nails
Correct answer: B
Rationale: Swollen, bleeding gums are a classic sign of scurvy, which is caused by a deficiency in Vitamin C. Dry, red conjunctiva, inflammation of the tongue, and pale, brittle nails are not specific manifestations of Vitamin C deficiency, making them incorrect choices.
4. A nurse is caring for four clients. The nurse should observe which of the following clients for a risk of vitamin B6 deficiency?
- A. A client who has cystic fibrosis
- B. A client who has chronic alcohol use disorder
- C. A client who takes phenytoin for a seizure disorder
- D. A client who is prescribed rifampin for tuberculosis
Correct answer: B
Rationale: Chronic alcohol use disorder can lead to vitamin B6 deficiency due to impaired absorption and increased excretion of the vitamin. While clients with cystic fibrosis may be at risk for fat-soluble vitamin deficiencies, such as vitamins A, D, E, and K, they are not specifically at high risk for vitamin B6 deficiency. Clients taking phenytoin are at risk for folate deficiency, not vitamin B6. Clients prescribed rifampin for tuberculosis are at risk for vitamin D deficiency, not vitamin B6.
5. 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.
