HESI CAT Exam
1. The healthcare provider prescribes a fluid challenge of 0.9% sodium chloride 1,000 ml to be infused over 4 hours. The IV administration set delivers 10gtt/ml. How many gtt/minute should the nurse regulate the infusion? (Enter a numeric value only. If rounding is required, round to the nearest whole number.)
- A. 42
- B.
- C.
- D.
Correct answer: A
Rationale: To calculate the rate: (1000 ml / 4 hours) = 250 ml/hour; (250 ml/hour) / (60 minutes/hour) = 4.17 ml/minute; (4.17 ml/minute) * (10 gtt/ml) = 41.7 gtt/minute, rounded to 42 gtt/minute. Therefore, the nurse should regulate the infusion at 42 gtt/minute to deliver the prescribed fluid challenge accurately. The other choices are incorrect as they do not reflect the correct calculation based on the given information.
2. The client who had a below-the-knee (BKA) amputation is being prepared for discharge to home. Which recommendation should the nurse provide this client?
- A. Inspect skin for redness
- B. Use a residual limb shrinker
- C. Apply alcohol to the stump after bathing
- D. Wash the stump with soap and water
Correct answer: D
Rationale: The correct recommendation for a client with a below-the-knee amputation preparing for discharge is to wash the stump with soap and water. This helps maintain cleanliness and prevent infection. Inspecting the skin for redness is important to monitor for signs of infection, but it is not a specific recommendation for a BKA amputation. Using a residual limb shrinker can aid in shaping and reducing swelling in the residual limb but is not usually done immediately after a BKA amputation. Applying alcohol to the stump after bathing is not recommended as it can lead to skin irritation and dryness.
3. The parents of a 6-year-old child recently diagnosed with Duchenne muscular dystrophy tell the nurse that their child wants to continue attending swimming classes. How should the nurse respond?
- A. Encourage the parents to allow the child to continue attending swimming lessons with supervision
- B. Suggest that the child be encouraged to participate in a team sport to promote socialization
- C. Explain that their child is not mature enough to understand the risks associated with swimming
- D. Provide a list of alternative activities that are less likely to cause the child to experience fatigue
Correct answer: A
Rationale: Encouraging the parents to allow the child to continue attending swimming lessons with supervision is the most appropriate response. Swimming can be beneficial for the child, providing both exercise and enjoyment. Supervision can help manage any risks associated with swimming. Choice B is incorrect because the child's preference for swimming should be respected, and swimming can still offer socialization opportunities. Choice C is incorrect as it undermines the child's capability to understand the situation. Choice D is less appropriate as it does not address the child's interest in swimming and may limit beneficial physical activity.
4. A client admitted to the intensive care unit with syndrome of inappropriate antidiuretic hormone (SIADH) has developed osmotic demyelination. Which intervention should the nurse implement first?
- A. Patch one eye.
- B. Reorient often.
- C. Range of motion.
- D. Evaluate swallow
Correct answer: B
Rationale: Frequent reorientation is crucial for clients with neurological impairments from osmotic demyelination to prevent confusion and assist with orientation. It helps maintain a proper sense of time, place, and person, reducing disorientation. Patching one eye (Choice A) is not a priority intervention for osmotic demyelination and does not address the immediate need for reorientation. Range of motion exercises (Choice C) may be important for overall care, but reorientation takes precedence due to its impact on neurological functioning. Evaluating swallow (Choice D) is not the primary intervention needed for osmotic demyelination; it is essential but not the first priority.
5. Identify the placement of the stapes footplate into the bony labyrinth.
- A. Fenestra vestibuli
- B. Fenestra cochleae
- C. Tympanic membrane
- D. Round window
Correct answer: A
Rationale: The correct answer is A: Fenestra vestibuli. The stapes footplate is placed into the fenestra vestibuli of the bony labyrinth. This structure is also known as the oval window and is located at the junction of the middle ear and inner ear. Choice B, Fenestra cochleae, is incorrect as this opening is also known as the round window and is located near the base of the cochlea. Choice C, Tympanic membrane, is incorrect as it is also known as the eardrum and separates the external ear from the middle ear. Choice D, Round window, is incorrect as it is the opening covered by the secondary tympanic membrane and is important for the dissipation of sound waves in the cochlea.
