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. A client with type 1 diabetes is found unconscious with a blood glucose of 40 mg/dL. What is the nurse's priority intervention?
- A. Administer a 50% dextrose bolus intravenously.
- B. Administer glucagon intramuscularly.
- C. Provide oral glucose gel.
- D. Recheck the blood glucose level in 15 minutes.
Correct answer: A
Rationale: The correct answer is to administer a 50% dextrose bolus intravenously. In unconscious clients with hypoglycemia, IV dextrose rapidly raises the blood glucose level. Glucagon would be a slower option and is typically used if IV access is unavailable. Oral glucose gel is not appropriate for an unconscious client as it requires swallowing and may cause aspiration. Rechecking the blood glucose level in 15 minutes delays immediate treatment and could lead to further deterioration.
3. A client who is taking clonidine (Catapres, Duraclon) reports drowsiness. Which additional assessment should the nurse make?
- A. How long has the client been taking the medication?
- B. Assess the client's dietary habits.
- C. Check for signs of infection.
- D. Evaluate the client's sleep pattern.
Correct answer: A
Rationale: The correct answer is A. When a client reports drowsiness while taking clonidine, the nurse should assess how long the client has been taking the medication. Drowsiness is a common side effect that can occur in the early weeks of treatment with clonidine. By understanding the duration of medication use, the nurse can determine if the drowsiness is a temporary effect that may decrease over time. Choices B, C, and D are incorrect because assessing the client's dietary habits, checking for signs of infection, or evaluating the client's sleep pattern would not directly address the drowsiness associated with clonidine use.
4. The nurse is assessing a client who has schizophrenia and is exhibiting symptoms of paranoia. Which behavior would the nurse most likely observe?
- A. The client is seen as unmotivated and withdrawn.
- B. The client is preoccupied with a fear of being harmed.
- C. The client displays a blunted affect and lacks emotional response.
- D. The client avoids group activities and shows decreased appetite.
Correct answer: B
Rationale: In clients with paranoia, they typically exhibit an intense fear of being harmed, persecuted, or targeted by others. This fear often dominates their thoughts and can significantly impact their daily functioning and interactions. Choice A, being unmotivated and withdrawn, is more indicative of negative symptoms of schizophrenia, such as avolition and social withdrawal. Choice C, displaying a blunted affect and lacking emotional response, is associated with flat affect, a symptom commonly seen in schizophrenia but not specific to paranoia. Choice D, avoiding group activities and showing decreased appetite, may be related to various symptoms or side effects, but it is not a defining characteristic of paranoia in schizophrenia.
5. Which of the following conditions is most commonly associated with a high risk of stroke?
- A. Hypertension.
- B. Diabetes.
- C. Obesity.
- D. Smoking.
Correct answer: A
Rationale: Hypertension is the correct answer. Hypertension, also known as high blood pressure, is a major risk factor for stroke because it puts increased pressure on blood vessels in the brain, making them more prone to damage and increasing the likelihood of a stroke. While diabetes, obesity, and smoking are also risk factors for stroke, hypertension is the most commonly associated condition with a high risk of stroke due to its direct impact on the blood vessels.
