HESI RN
HESI Fundamentals Practice Test
1. After hemodialysis, a client with a history of chronic renal failure has just returned to the unit. What is the most important assessment for the nurse to make?
- A. Auscultate the client's lung sounds.
- B. Assess the client's blood pressure.
- C. Monitor the client's weight.
- D. Check the client's fistula for bruit and thrill.
Correct answer: D
Rationale: The most crucial assessment for the nurse to make after hemodialysis in a client with chronic renal failure is to check the client's fistula for bruit and thrill (D). This assessment is essential to ensure the patency of the fistula and adequate blood flow. Auscultating lung sounds (A), assessing blood pressure (B), and monitoring weight (C) are important assessments but are secondary to evaluating the fistula. Checking the fistula is vital as it directly impacts the effectiveness of the client's dialysis treatment and the patency of the vascular access, ensuring successful dialysis sessions.
2. A public health nurse is working with a community to improve access to healthcare services. Which intervention is most likely to be effective?
- A. Setting up mobile clinics in underserved areas
- B. Distributing flyers with information about local clinics
- C. Offering transportation vouchers for medical appointments
- D. Partnering with local businesses to provide healthcare discounts
Correct answer: A
Rationale: Setting up mobile clinics in underserved areas is the most effective intervention to improve access to healthcare services. Mobile clinics directly bring healthcare services to the community, making it convenient for residents to access care without having to travel long distances. Distributing flyers may increase awareness but may not address the barriers to access. Offering transportation vouchers helps with one aspect of access but does not directly provide healthcare services. Partnering with local businesses for discounts may not address the primary issue of physical access to healthcare services in underserved areas.
3. Which of the following is an interpersonal activity of nurse managers, but not necessarily all nurse leaders?
- A. Coaching
- B. Resource allocation
- C. Planning for the future
- D. Monitoring
Correct answer: A
Rationale: The correct answer is A: Coaching. Nurse managers are directly involved in coaching their team members, providing guidance, support, and mentorship. This is a key interpersonal activity that focuses on developing the skills and performance of individual team members. While nurse leaders may also engage in coaching activities, it is a more specific and hands-on role for nurse managers. Choice B, resource allocation, is a managerial function that involves distributing resources effectively and efficiently. Choice C, planning for the future, is a strategic activity that involves setting goals and directions for the organization. Choice D, monitoring, is a supervisory task that involves overseeing and evaluating processes and outcomes. These activities are important for nurse leaders as well as nurse managers, but coaching is a more direct interpersonal interaction typically associated with nurse managers.
4. What characteristic of water allows for hydrogen bonding between molecules?
- A. Its covalent bonds
- B. Its cohesive properties
- C. Its high specific heat
- D. Its polar nature
Correct answer: D
Rationale: The correct answer is D: Its polar nature. Water is a polar molecule with a partial positive charge on hydrogen atoms and a partial negative charge on oxygen atoms. This polarity allows water molecules to form hydrogen bonds with each other. Choice A, covalent bonds, is incorrect because while water indeed has covalent bonds, they do not directly enable hydrogen bonding. Choice B, cohesive properties, is incorrect as cohesion refers to water's ability to stick to other substances, not the specific characteristic that allows for hydrogen bonding. Choice C, high specific heat, is also incorrect as it refers to water's ability to resist changes in temperature, not its property that leads to hydrogen bonding.
5. The nurse is caring for a client post appendectomy. The client has developed a fever, and the incision site is red and swollen. Which of these assessments is a priority for the nurse to perform?
- A. Check the client's blood pressure
- B. Assess the client's pain level
- C. Inspect the incision site
- D. Monitor the client's respiratory status
Correct answer: C
Rationale: Inspecting the incision site is a priority in this situation because the redness and swelling indicate a potential infection. This assessment helps the nurse determine the extent of infection and the appropriate intervention, such as administering antibiotics or notifying the healthcare provider. Checking the client's blood pressure (Choice A) may be important but is not the priority in this scenario where signs of infection are present. Assessing the client's pain level (Choice B) is also important but addressing the infection takes precedence. Monitoring the client's respiratory status (Choice D) is essential but not the priority when dealing with a localized infection at the incision site.
