HESI CAT Exam 2024
1. A young adult woman visits the clinic and learns that she is positive for BRCA1 gene mutation and asks the nurse what to expect next. How should the nurse respond?
- A. Explain that counseling will be provided to give her information about her cancer risk.
- B. Gather additional information about the client’s family history for all types of cancer.
- C. Offer assurance that there are a variety of effective treatments for breast cancer.
- D. Provide information about survival rates for women who have this genetic mutation.
Correct answer: A
Rationale: The correct answer is A because counseling will help the woman understand her risk and options for surveillance or preventive measures. At this point, it is crucial to address the woman's immediate concerns related to the BRCA1 gene mutation. Choice B is incorrect as the focus should be on the woman's individual risk due to the specific gene mutation she carries. Choice C is not the priority as treatment options come after assessing the risk and deciding on surveillance or preventive measures. Choice D is incorrect because discussing survival rates is not the immediate need for someone who has just received information about having a genetic mutation.
2. After mitosis, the genetic code is identical in new cells unless _________ occur through radiation or other environmental influences.
- A. reductions
- B. expulsions
- C. conceptions
- D. mutations
Correct answer: D
Rationale: After mitosis, the genetic code is typically preserved and remains identical in the new cells. However, mutations can occur due to radiation or environmental influences, leading to changes in the DNA sequence and potentially altering the genetic code. Therefore, the correct answer is 'mutations.' Choices A, B, and C are incorrect because reductions, expulsions, and conceptions do not accurately describe the changes in the genetic code that can result from external factors. Mutations are the only option that reflects the alteration in the genetic code caused by external influences, making it the correct choice in this context.
3. While providing oral care for a client who is unconscious, the nurse positions the client laterally and uses a basin to collect secretions. Which intervention is best for the nurse to implement?
- A. Swab the oral cavity with a washcloth
- B. Use oral swabs with normal saline
- C. Provide a Yankauer tip for oral suction
- D. Support the head with a small pillow
Correct answer: B
Rationale: Using oral swabs with normal saline is the best intervention in this scenario as it effectively cleans the oral cavity without causing irritation or dryness, which is crucial for an unconscious client. Swabbing the oral cavity with a washcloth may not provide thorough cleaning, and it can potentially cause irritation. Providing a Yankauer tip for oral suction is not necessary unless there are excessive secretions that need to be suctioned. Supporting the head with a small pillow, although important for comfort, is not directly related to oral care in an unconscious client.
4. What is an important nursing consideration for a child with a diagnosis of juvenile idiopathic arthritis (JIA) being treated with methotrexate?
- A. Monitor liver function tests regularly
- B. Encourage regular exercise
- C. Provide high-calorie snacks
- D. Encourage frequent handwashing
Correct answer: A
Rationale: The correct answer is to monitor liver function tests regularly. Methotrexate, commonly used in JIA, can be hepatotoxic. Regular monitoring of liver function tests is crucial to detect any signs of liver damage early. While encouraging regular exercise (choice B) is generally beneficial for overall health, it is not directly related to methotrexate therapy. Providing high-calorie snacks (choice C) is not a necessary consideration in this context and can be misleading. Encouraging frequent handwashing (choice D) is important for infection control but is not specifically related to the medication methotrexate.
5. The school nurse is caring for a boy with hemophilia who fell on his arm during recess. What supportive measures should the nurse use until factor replacement therapy can be instituted?
- A. Apply warm, moist compresses
- B. Apply pressure for at least 1 minute
- C. Elevate the area above the level of the heart
- D. Begin passive range-of-motion unless the pain is severe
Correct answer: C
Rationale: Elevating the affected area above the level of the heart is the correct supportive measure for a child with hemophilia who has experienced trauma. This action helps reduce bleeding and swelling by promoting venous return and preventing further pooling of blood in the affected area. Applying warm, moist compresses (Choice A) may not be recommended as it can potentially increase bleeding by dilating blood vessels. Applying pressure for at least 1 minute (Choice B) can be helpful for minor cuts or wounds but may not be as effective in managing bleeding in a child with hemophilia. Beginning passive range-of-motion (Choice D) should be avoided as it can exacerbate bleeding and cause further damage in a child with hemophilia.
