1. A healthcare professional prepares to administer a scheduled dose of labetalol by mouth to a client with hypertension. The client's heart rate is 48 beats/min, respirations are 16 breaths/min, and blood pressure is 150/90 mmHg.
- A. Administer the dose and monitor the client's blood pressure regularly
- B. Apply a telemetry monitor before administering the dose
- C. Assess for orthostatic hypotension before administering the dose
- D. Withhold the scheduled dose and notify the healthcare provider
Correct answer: D
Rationale: The client's low heart rate of 48 beats/min indicates bradycardia, a potential side effect of labetalol. Administering the dose in this case could further lower the heart rate, potentially causing adverse effects. Therefore, it is crucial to withhold the scheduled dose and notify the healthcare provider for further assessment and guidance. Choice A is incorrect because administering the dose without addressing the bradycardia can exacerbate the condition. Choice B is not relevant in this situation as telemetry monitoring is not the priority. Choice C is also not the priority in this case, as the focus should be on the client's bradycardia and the potential adverse effects of administering labetalol.
2. A client reports abdominal pain. An assessment by the nurse reveals a temperature of 39.2 degrees C (102 degrees F), heart rate of 105/min, a soft tender abdomen, and menses overdue by 2 days. Which of the following findings should be the nurse's priority?
- A. Temperature
- B. Heart rate
- C. Abdominal tenderness
- D. Overdue menses
Correct answer: A
Rationale: The nurse's priority should be the client's temperature. A high temperature of 39.2 degrees C (102 degrees F) indicates a potential infection or inflammation that requires immediate attention. While heart rate and abdominal tenderness are important assessments, the temperature takes precedence as it signals a more urgent issue. Overdue menses, although significant, are not the priority in this scenario when compared to the possibility of an acute infection or inflammatory process.
3. Under the provisions of the Americans with Disabilities Act, what are nurse managers required to do?
- A. Maintain an environment free from associated hazards
- B. Provide reasonable accommodations for disabled individuals
- C. Make all necessary accommodations for disabled individuals
- D. Consider both mental and physical disabilities
Correct answer: B
Rationale: The correct answer is B: 'Provide reasonable accommodations for disabled individuals.' The Americans with Disabilities Act (ADA) mandates nurse managers to offer reasonable accommodations for disabled individuals to ensure equal opportunities in the workplace. Choice A is incorrect because although maintaining a hazard-free environment is essential, the focus of the ADA is on accommodations for disabled individuals. Choice C is incorrect as it overly generalizes the accommodations without specifying the need for them to be 'reasonable.' Choice D is incorrect because the ADA does not specify a requirement to consider both mental and physical disabilities; instead, it emphasizes providing reasonable accommodations regardless of the disability type.
4. Diabetes insipidus is the result of:
- A. A diet high in sugar and carbohydrates.
- B. A complicated pregnancy.
- C. A disorder of the pancreas.
- D. A disorder of the pituitary gland.
Correct answer: D
Rationale: Diabetes insipidus is caused by a disorder of the pituitary gland affecting ADH regulation. This disorder results in the decreased production or release of antidiuretic hormone (ADH), leading to the inability of the kidneys to concentrate urine properly. Choices A, B, and C are incorrect as they do not relate to the underlying cause of diabetes insipidus.
5. A client reports feeling dizzy and light-headed when standing up. What is the nurse's best initial action?
- A. Instruct the client to sit or lie down
- B. Monitor blood pressure and pulse
- C. Administer an anti-dizziness medication
- D. Increase fluid intake
Correct answer: B
Rationale: The correct answer is B: Monitor blood pressure and pulse. When a client reports feeling dizzy and light-headed when standing up, the nurse's best initial action should be to monitor the client's blood pressure and pulse. These symptoms are indicative of orthostatic hypotension, which can be confirmed by changes in blood pressure and pulse when moving from lying to standing positions. Instructing the client to sit or lie down may provide temporary relief but does not address the underlying cause. Administering an anti-dizziness medication should not be the initial action without assessing vital signs first. Increasing fluid intake is important for overall health but is not the priority in this situation where vital sign monitoring is needed to assess for orthostatic hypotension.
