HESI CAT Exam 2024
1. A young adult client was admitted 36 hours ago for a head injury that occurred as a result of a motorcycle accident. In the last 4 hours, the client’s urine output has increased to over 200 ml/hour. Before reporting the finding to the healthcare provider, which intervention should the nurse implement?
- A. Obtain capillary blood samples for glucose every 2 hours
- B. Measure oral secretions suctioned during the last 4 hours
- C. Evaluate the urine osmolality and serum osmolality values
- D. Obtain blood pressure and assess for dependent edema
Correct answer: C
Rationale: The correct answer is to evaluate the urine osmolality and serum osmolality values. The increased urine output following a head injury could indicate diabetes insipidus, a condition characterized by excessive urination and extreme thirst. Evaluating osmolality is crucial for diagnosing diabetes insipidus. Choice A is incorrect because obtaining capillary blood samples for glucose every 2 hours is not the priority in this situation. Choice B is irrelevant to the client's current symptom of increased urine output. Choice D is also not the most appropriate intervention as the focus should be on assessing for a potential endocrine issue related to the increased urine output.
2. In what order should the nurse perform the steps of a surgical hand scrub prior to entering the operating room?
- A. Rinse from the fingertips to the elbow
- B. Scrape under the nails with a nail pick
- C. Use a soapy brush to scrub the hands
- D. Cleanse the arm with a lathered brush
Correct answer: B
Rationale: The correct order for performing a surgical hand scrub is to first scrape under the nails with a nail pick, then scrub the hands using a soapy brush, cleanse the arms, and finally rinse. This sequence ensures thorough cleaning and minimizes the risk of contamination. Choice A is incorrect because rinsing should be the final step, not the first. Choice C is incorrect as scrubbing the hands comes after scraping under the nails. Choice D is incorrect as cleansing the arms should follow hand scrubbing, not precede it.
3. A client with a large pleural effusion undergoes a thoracentesis. Following the procedure, which assessment finding warrants immediate intervention by the nurse?
- A. The client has asymmetrical chest wall expansion
- B. The client complains of pain at the insertion site
- C. The client's chest x-ray indicates decreased pleural effusion
- D. The client's arterial blood gases show pH 7.35, PaO2 85, PaCO2 35, HCO3 26
Correct answer: A
Rationale: Asymmetrical chest wall expansion is a critical finding post-thoracentesis as it may suggest a pneumothorax, requiring immediate intervention to prevent further complications. The other options, such as pain at the insertion site (Choice B), decreased pleural effusion on chest x-ray (Choice C), and normal arterial blood gases within acceptable ranges (Choice D) do not indicate an immediate need for intervention like asymmetrical chest wall expansion does.
4. A 5-week-old infant who developed projectile vomiting over the last two weeks is diagnosed with hypertrophic pyloric stenosis. Which intervention should the nurse plan to implement?
- A. Instruct the mother to give the child sugar water only
- B. Maintain intravenous fluid therapy per prescription
- C. Provide Pedialyte feedings via the nasogastric tube
- D. Offer the infant Pedialyte feedings every 2 hours
Correct answer: B
Rationale: Maintaining intravenous fluid therapy is crucial for managing dehydration and electrolyte imbalances caused by the vomiting in hypertrophic pyloric stenosis. Instructing the mother to give sugar water only (Choice A) is not appropriate as it does not address the dehydration and electrolyte imbalances adequately. Providing Pedialyte feedings via the nasogastric tube (Choice C) may not be sufficient to manage the severe fluid and electrolyte losses caused by the condition. Offering Pedialyte feedings every 2 hours (Choice D) may not be as effective as maintaining intravenous fluid therapy, especially in cases where rapid rehydration is necessary.
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.
