HESI RN Exit Exam
1. After placing a stethoscope as seen in the picture, the nurse auscultates S1 and S2 heart sounds. To determine if an S3 heart sound is present, what action should the nurse take first?
- A. Slide the stethoscope across the sternum.
- B. Move the stethoscope to the mitral site.
- C. Listen with the bell at the same location.
- D. Observe the cardiac telemetry monitor.
Correct answer: C
Rationale: The nurse uses the bell of the stethoscope to hear low-pitched sounds such as S3 and S4. To determine if an S3 heart sound is present, the nurse should listen at the same location using the bell first. This allows for the accurate identification of low-pitched sounds. Moving the stethoscope across the sternum (Choice A) or to the mitral site (Choice B) would not be the initial actions to assess for an S3 heart sound. Observing the cardiac telemetry monitor (Choice D) is not relevant for assessing S3 heart sounds, as it does not provide direct auscultation of heart sounds.
2. Scientific management and human relations-based approach are two major theoretical management schools of thought. Which of the following best describes the scientific model of management?
- A. A nurse manager considers methods of motivating the staff to do their assigned tasks.
- B. A nurse manager commends staff for the work they do, reminding them of the importance of their work and the lives they have saved.
- C. A nurse manager analyzes the role of each staff member on the unit to determine ways to increase efficiency.
- D. A conflict between two staff nurses has impacted an entire unit. The unit manager meets with the nurses and entire staff to promote mutual understanding.
Correct answer: C
Rationale: The correct answer is C because scientific management focuses on improving efficiency through the analysis of tasks and work processes. Choice A is more aligned with a human relations-based approach, which emphasizes motivation and relationships. Choice B reflects recognition and morale boosting, which is also characteristic of the human relations approach. Choice D involves conflict resolution and promoting mutual understanding, which is related to the human relations approach rather than scientific management.
3. In a patient with asthma, which of the following is the most important indicator of respiratory function?
- A. Oxygen saturation.
- B. Respiratory rate.
- C. Arterial blood gases.
- D. Peak expiratory flow rate.
Correct answer: D
Rationale: The peak expiratory flow rate is the most important indicator of respiratory function in asthma because it measures how quickly air can be exhaled, reflecting the severity of airflow limitation. Oxygen saturation (Choice A) is important in assessing oxygenation, but it does not directly reflect respiratory function. Respiratory rate (Choice B) can provide information on breathing patterns but does not quantify airflow limitation. Arterial blood gases (Choice C) give information about gas exchange but are not as specific for assessing asthma control and severity as peak expiratory flow rate.
4. The nurse is caring for a client following a craniotomy. Which finding should the nurse report immediately?
- A. Pupils equal and reactive to light.
- B. Sudden increase in urine output.
- C. Diminished breath sounds bilaterally.
- D. Increase in blood pressure by 20 mmHg.
Correct answer: C
Rationale: The correct answer is C, 'Diminished breath sounds bilaterally.' This finding should be reported immediately as it could indicate a serious complication such as increased intracranial pressure or respiratory compromise. In a post-craniotomy client, changes in breath sounds may be a sign of developing issues that need prompt intervention. Choices A, B, and D are not as critical in the immediate post-craniotomy period. Pupils equal and reactive to light are expected findings, a sudden increase in urine output may require monitoring but not immediate reporting, and a small increase in blood pressure may not be alarming unless it is significantly high or accompanied by other concerning signs.
5. The client with DM is being taught by the nurse about the importance of monitoring blood glucose levels. The nurse should instruct the client to:
- A. Check blood glucose only when feeling unwell.
- B. Check blood glucose before meals and at bedtime.
- C. Check blood glucose only after meals.
- D. Check blood glucose only in the morning.
Correct answer: B
Rationale: The correct answer is to check blood glucose before meals and at bedtime. Monitoring blood glucose levels before meals allows the client to adjust their insulin or oral antidiabetic medications based on their current levels. Checking at bedtime helps in ensuring blood glucose levels are at a safe range throughout the night. Option A is incorrect because blood glucose should be monitored regularly as part of diabetes management, not just when feeling unwell. Option C is incorrect because checking only after meals does not provide a complete picture of blood glucose control throughout the day. Option D is incorrect as checking only in the morning does not cover the full spectrum of blood glucose variations that can occur during the day.
