HESI RN
HESI Medical Surgical Exam
1. After a myocardial infarction, why is the hospitalized client taught to move the legs while resting in bed?
- A. Prepare the client for ambulation.
- B. Promote urinary and intestinal elimination.
- C. Prevent thrombophlebitis and blood clot formation.
- D. Decrease the likelihood of pressure ulcer formation.
Correct answer: C
Rationale: The correct answer is C. Moving the legs helps prevent thrombophlebitis and blood clot formation by promoting venous return in clients on bed rest. This prevents stasis and clot formation in the lower extremities. Choices A, B, and D are incorrect because the primary goal of moving the legs is to prevent thrombophlebitis and blood clot formation, rather than preparing for ambulation, promoting elimination, or decreasing pressure ulcer formation. Ambulation preparation involves different exercises, urinary and intestinal elimination are not directly related to leg movements, and pressure ulcer prevention is more related to repositioning and skin care.
2. The nurse accepts a transfer to the mental health unit and understands that the client is distractible and is exhibiting a decreased ability to concentrate. The nurse has only 15 minutes to talk with the client. To develop a treatment plan for this client, which assessment is most important for the nurse to obtain?
- A. Motivation for treatment
- B. History of substance use
- C. Medication compliance
- D. Mental status examination
Correct answer: D
Rationale: A mental status examination is the most important assessment for the nurse to obtain in this scenario. It provides a comprehensive view of the client's current cognitive functioning, including their level of alertness, orientation, memory, attention, and thought process. Understanding the client's mental status is crucial for developing an appropriate treatment plan. The other options, such as motivation for treatment, history of substance use, and medication compliance, are important aspects to consider but may not directly address the client's current cognitive state and immediate treatment needs as effectively as a mental status examination.
3. A client is placed on a mechanical ventilator following a cerebral hemorrhage, and vecuronium bromide (Norcuron) 0.04 mg/kg q12 hours IV is prescribed. What is the priority nursing diagnosis for this client?
- A. Impaired communication related to paralysis of skeletal muscles.
- B. High risk for infection related to increased intracranial pressure.
- C. Potential for injury related to impaired lung expansion.
- D. Social isolation related to inability to communicate.
Correct answer: A
Rationale: The priority nursing diagnosis for a client on a mechanical ventilator receiving vecuronium bromide is 'Impaired communication related to paralysis of skeletal muscles.' Vecuronium is a skeletal muscle relaxant that causes diaphragmatic paralysis, leading to the inability of the client to communicate effectively. This is a crucial nursing concern as it impacts the client's ability to express needs and participate in care. Option B 'High risk for infection related to increased intracranial pressure' is not the priority in this scenario as the client's condition is related to the effects of the medication and mechanical ventilation, not directly to increased intracranial pressure. Option C 'Potential for injury related to impaired lung expansion' is important but not the priority over impaired communication. Option D 'Social isolation related to inability to communicate' is not the priority nursing diagnosis in this situation as it focuses more on psychosocial aspects rather than the immediate physiological concern of communication impairment.
4. A client with rheumatoid arthritis is scheduled to receive a dose of methotrexate. Which laboratory result is most important for the nurse to review before administering the medication?
- A. White blood cell count
- B. Liver function tests
- C. Kidney function tests
- D. Complete blood count
Correct answer: B
Rationale: The correct answer is B: Liver function tests. Before administering methotrexate, it is crucial to review liver function tests due to the medication's potential hepatotoxic effects. Methotrexate can cause liver damage, so monitoring liver function is essential to prevent any serious complications. While white blood cell count, kidney function tests, and complete blood count are important parameters to monitor in certain situations, they are not the most critical before administering methotrexate.
5. An 86-year-old nursing home resident who has decreased mental status is hospitalized with pneumonic infiltrates in the right lower lobe. When the nurse assists the client with a clear liquid diet, the client begins to cough. What should the nurse do next?
- A. Add a thickening agent to the fluids
- B. Check the client's gag reflex
- C. Feed the client only solid foods
- D. Increase the rate of intravenous fluids
Correct answer: B
Rationale: Checking the client's gag reflex is the appropriate action in this scenario. It helps assess the client's ability to swallow safely without the risk of aspiration. Adding a thickening agent to the fluids (Choice A) may be considered later if swallowing difficulties persist. Feeding the client only solid foods (Choice C) can increase the risk of aspiration in this case, and increasing the rate of intravenous fluids (Choice D) does not address the swallowing concern.
