HESI RN
Evolve HESI Medical Surgical Practice Exam
1. A client tells the nurse that he has been experiencing frequent heartburn and has been 'living on antacids.' For which acid-base disturbance does the nurse recognize a risk?
- A. Metabolic acidosis
- B. Metabolic alkalosis
- C. Respiratory acidosis
- D. Respiratory alkalosis
Correct answer: B
Rationale: The correct answer is B: Metabolic alkalosis. In this scenario, the client's frequent use of antacids containing alkaline components can lead to an excess of bicarbonate in the body, causing metabolic alkalosis. Oral antacids work by neutralizing stomach acid, potentially leading to an alkaline shift in the body's pH balance. Choices A, C, and D are incorrect. Metabolic acidosis is not typically associated with antacid use. Respiratory acidosis and respiratory alkalosis are related to respiratory system dysfunction rather than antacid ingestion.
2. Oligomenorrhea is defined as a cycle longer than:
- A. 28 days
- B. 30 days
- C. 35 days
- D. 40 days
Correct answer: C
Rationale: Oligomenorrhea is defined as a menstrual cycle longer than 35 days. A cycle of 28 days (Choice A) is within the normal range, and not considered oligomenorrhea. Similarly, 30 days (Choice B) and 40 days (Choice D) are also within the normal range. The correct definition of oligomenorrhea specifically refers to cycles longer than 35 days, making Choice C the correct answer.
3. Laboratory findings indicate that a client's serum potassium level is 2.5 mEq/L. What action should the nurse take?
- A. Inform the healthcare provider of the need for potassium replacement.
- B. Prepare to administer a glucose-insulin-potassium replacement.
- C. Change the plan of care to include hourly urinary output measurement.
- D. Instruct the client to increase daily intake of potassium-rich foods.
Correct answer: A
Rationale: A serum potassium level of 2.5 mEq/L is critically low, indicating severe hypokalemia. The immediate action the nurse should take is to inform the healthcare provider of the need for potassium replacement. Option B, preparing to administer glucose-insulin-potassium replacement, is not the first-line intervention; it may be considered in specific situations but requires a healthcare provider's prescription. Option C, changing the plan of care to include hourly urinary output measurement, is not the priority when managing critically low potassium levels. Option D, instructing the client to increase daily intake of potassium-rich foods, is not appropriate in this acute situation where immediate intervention is needed to address the dangerously low potassium level.
4. A client with lung cancer is admitted to palliative care. What is the nurse's priority assessment?
- A. Monitor respiratory status and oxygenation.
- B. Evaluate the client's mental status and cognition.
- C. Check the client’s pain level and provide comfort.
- D. Assess the client’s nutritional status and appetite.
Correct answer: A
Rationale: Correct Answer: Monitoring respiratory status and oxygenation is crucial in clients with lung cancer, as metastasis to the lungs or pleural effusion can compromise breathing. This assessment helps in early identification of respiratory distress and the need for interventions to maintain adequate oxygenation. Choice B is important but not the priority in this situation. Evaluating mental status and cognition should follow after ensuring the client's physiological needs are met. Choice C, checking pain level and providing comfort, is essential but secondary to assessing respiratory status. Choice D, assessing nutritional status and appetite, is also important but not the priority when the client's breathing is at risk.
5. A 20-year-old client has an infected leg wound from a motorcycle accident and has returned home from the hospital. The client is to keep the affected leg elevated and is on contact precautions. The client wants to know if visitors can come. The appropriate response from the home health nurse is that:
- A. Visitors must wear a mask and a gown
- B. There are no special requirements for visitors of clients on contact precautions
- C. Visitors should wash their hands before and after touching the client
- D. Visitors -
Correct answer: C
Rationale: The correct answer is C: 'Visitors should wash their hands before and after touching the client.' When a client is on contact precautions, it is essential for visitors to practice good hand hygiene to prevent the spread of infection. While wearing a mask and a gown might be necessary for healthcare providers, it is not typically required for visitors. Option B is incorrect because there are indeed special requirements for visitors on contact precautions, including practicing good hand hygiene. Option D is incomplete and does not provide any guidance on infection prevention measures.
