HESI CAT Exam
1. A client is admitted to a medical unit with the diagnosis of gastritis and chronic heavy alcohol abuse. What should the nurse administer to prevent the development of Wernicke's syndrome?
- A. Lorazepam (Ativan)
- B. Famotidine (Pepcid)
- C. Thiamine (Vitamin B1)
- D. Atenolol (Tenormin)
Correct answer: C
Rationale: Thiamine supplementation is critical in preventing Wernicke's syndrome, especially in clients with chronic alcohol use. Wernicke's syndrome is a neurological disorder caused by thiamine deficiency. Lorazepam is a benzodiazepine used for anxiety and not for preventing Wernicke's syndrome. Famotidine is an H2 blocker used to reduce stomach acid production but does not prevent Wernicke's syndrome. Atenolol is a beta-blocker used for hypertension and angina, not for preventing Wernicke's syndrome.
2. A client receives a prescription for acetylcysteine (Mucomyst) 1.4 grams per nasogastric tube q4 hours. Acetylcysteine is available as a 10% solution (10 grams/100ml). How many ml of the 10% solution should the nurse administer per dose?
- A. 7
- B. 10
- C. 14
- D. 1.4 grams of acetylcysteine is equivalent to 14 ml of a 10% solution.
Correct answer: D
Rationale: To determine the amount of the 10% acetylcysteine solution to administer, convert the 1.4 grams to milligrams (1.4 grams = 1400 mg). Then, as the 10% solution contains 10 grams (10,000 mg) per 100 ml, it means there are 1000 mg of acetylcysteine in every 10 ml of the solution (10,000 mg / 100 ml = 100 mg/ml). Therefore, to administer 1400 mg (1.4 grams) of acetylcysteine, the nurse should give 14 ml of the 10% solution. Choices A, B, and C are incorrect as they do not accurately convert the amount of acetylcysteine to the corresponding volume of the 10% solution.
3. The parents of a child who had surgical repair of a myelomeningocele are being taught how to change an occlusive dressing on the child’s back. Which statement by the parents indicates that they understand this procedure?
- A. When changing the dressing, the tape should be removed slowly to prevent trauma to the skin
- B. To prevent infection, the dressing should be kept dry to avoid excess moisture
- C. The skin incision should be kept moist to promote healing and prevent dryness
- D. The incision should be protected from fecal contamination by an intact dressing
Correct answer: D
Rationale: The correct answer is D because protecting the incision from fecal contamination is essential to prevent infection and promote healing in a child with a myelomeningocele. This is crucial as fecal matter can introduce harmful bacteria to the wound. Choice A is incorrect as removing the tape slowly to prevent trauma to the skin is a general guideline but not specific to preventing infection. Choice B is incorrect because keeping the dressing dry can lead to complications as the wound needs a moist environment to heal properly. Choice C is incorrect as keeping the skin incision moist may promote infection and delay healing, making it an incorrect statement for postoperative care.
4. When assessing a client's blood pressure and determining an auscultatory gap, which action should the nurse implement?
- A. Compare the palpated systolic blood pressure with the auscultated pressure
- B. Assess the client for lightheadedness upon standing
- C. Determine if an automated blood pressure reading is consistent with the manual reading
- D. Observe for changes in blood pressure between lying and sitting positions
Correct answer: A
Rationale: When an auscultatory gap is present, comparing the palpated systolic blood pressure with the auscultated pressure is crucial. This helps to accurately measure blood pressure and detect any discrepancies caused by the gap. Assessing for lightheadedness upon standing (choice B) is unrelated to addressing an auscultatory gap. Checking the consistency between automated and manual blood pressure readings (choice C) is important for validation but not specifically for managing an auscultatory gap. Observing blood pressure changes between lying and sitting positions (choice D) is relevant for orthostatic hypotension assessment but not for dealing with an auscultatory gap.
5. A client with a severe prostatic infection that caused a blocked urethra is 3 days post-surgical urinary diversion. The healthcare provider directs the nurse to remove the suprapubic catheter to allow the client to void normally. Which intervention should the nurse implement first?
- A. Cleanse the site around the catheter
- B. Use a 20 ml syringe to deflate balloon
- C. Clamp catheter until the client voids naturally
- D. Empty urine from the urinary drainage bag
Correct answer: B
Rationale: The correct answer is to use a 20 ml syringe to deflate the balloon first when removing a suprapubic catheter. This step is essential to ensure the safe removal of the catheter without causing any harm or discomfort to the client. Deflating the balloon allows for the catheter to be easily removed. Option A, cleansing the site around the catheter, is not the initial step in this process and can be done after catheter removal. Option C, clamping the catheter until the client voids naturally, is incorrect as it can lead to complications like urinary retention. Option D, emptying urine from the urinary drainage bag, is not the first step in removing the suprapubic catheter and does not address the need to deflate the balloon for safe removal.
