HESI RN Exit Exam 2023
1. A client with a history of chronic obstructive pulmonary disease (COPD) is admitted with an exacerbation. Which laboratory value should be monitored closely?
- A. Arterial blood gas (ABG) values
- B. Serum potassium level
- C. Serum sodium level
- D. Serum magnesium level
Correct answer: B
Rationale: The correct answer is B: Serum potassium level. In COPD, especially when the client is receiving diuretics or corticosteroids, monitoring serum potassium levels is crucial. These medications can lead to potassium loss, potentially causing hypokalemia. Arterial blood gas (choice A) values are important in assessing respiratory status but are not the primary concern related to medication side effects. Serum sodium (choice C) and magnesium (choice D) levels are also important, but in the context of COPD exacerbation and medication effects, potassium monitoring takes precedence.
2. A client is diagnosed with methicillin-resistant Staphylococcus aureus pneumonia. What type of isolation is most appropriate for this client?
- A. Reverse
- B. Airborne
- C. Standard precautions
- D. Contact
Correct answer: D
Rationale: The correct answer is 'D: Contact.' Contact precautions are necessary for clients with MRSA pneumonia to prevent the spread of the resistant bacteria. MRSA is primarily spread by direct contact, so using contact precautions, such as wearing gloves and gowns, is essential. Choice A, 'Reverse,' is not a type of isolation precaution. Choice B, 'Airborne,' is not the appropriate isolation for MRSA pneumonia, as MRSA is not transmitted through the airborne route. Choice C, 'Standard precautions,' are important for all clients, but for MRSA pneumonia specifically, contact precautions are more targeted and necessary.
3. A client with a history of substance abuse is admitted to the hospital for treatment of a new illness. Which of the following is the most important to assess upon admission?
- A. History of recent drug use.
- B. Current employment status.
- C. Family history of mental illness.
- D. Recent weight changes.
Correct answer: A
Rationale: Assessing the history of recent drug use is crucial when admitting a client with a history of substance abuse. Understanding recent drug use helps in managing potential withdrawal symptoms, preventing drug interactions with the new treatment, and ensuring appropriate care. Assessing current employment status (choice B) is important for social and financial support but is not as crucial as assessing recent drug use in this scenario. Family history of mental illness (choice C) and recent weight changes (choice D) are also important aspects of assessment but are not as immediate and critical as evaluating recent drug use in a client with a history of substance abuse.
4. A client with chronic renal failure is prescribed a low-protein diet. The nurse should explain to the client that the purpose of this diet is to:
- A. Prevent fluid overload.
- B. Reduce the workload on the kidneys.
- C. Prevent dehydration.
- D. Maintain electrolyte balance.
Correct answer: B
Rationale: The correct answer is B: 'Reduce the workload on the kidneys.' A low-protein diet is prescribed for clients with chronic renal failure to decrease the production of urea and other nitrogenous wastes, which can accumulate in the body when the kidneys are not functioning properly. This reduction in protein intake helps to lessen the burden on the kidneys, as they may have difficulty in filtering and excreting waste products. Choice A is incorrect because fluid overload is more related to restrictions in fluid intake rather than protein intake. Choice C is incorrect as a low-protein diet does not directly prevent dehydration. Choice D is incorrect because while electrolyte balance is essential in renal failure, the primary purpose of a low-protein diet is to reduce the workload on the kidneys by limiting the production of waste products.
5. A client with pneumonia is prescribed antibiotics. What is the most important teaching point for the nurse to provide?
- A. Instruct the client to rest as much as possible.
- B. Encourage increased fluid intake to thin secretions.
- C. Explain the importance of completing the entire course of antibiotics.
- D. Instruct the client to stop taking antibiotics once symptoms subside.
Correct answer: C
Rationale: The correct answer is C. Antibiotics must be taken for the entire prescribed duration to ensure that the infection is completely eradicated. Stopping antibiotics early, even if symptoms improve, can lead to a recurrence of the infection or antibiotic resistance. Choice A is incorrect because though rest is important, completing the antibiotic course is crucial. Choice B is incorrect as while hydration is beneficial, completing the antibiotics is the priority. Choice D is incorrect as stopping antibiotics prematurely can have negative consequences.
