1. What is the primary purpose of performing range-of-motion (ROM) exercises?
- A. To improve cardiovascular fitness
- B. To prevent muscle atrophy and joint contractures
- C. To increase respiratory function
- D. To enhance cognitive function
Correct answer: B
Rationale: The primary purpose of performing range-of-motion (ROM) exercises is to prevent muscle atrophy and joint contractures. These exercises are crucial in maintaining joint mobility and muscle flexibility, especially in patients who are immobilized or have limited mobility. Improving cardiovascular fitness (Choice A) involves different types of exercises that target the heart and blood vessels, not specifically ROM exercises. Increasing respiratory function (Choice C) is typically achieved through breathing exercises and activities that enhance lung capacity. Enhancing cognitive function (Choice D) is usually addressed through cognitive exercises and activities that stimulate brain function.
2. What title should be given to this professional role in occupational health? A registered nurse who develops researchable questions, conducts research, and communicates the findings to occupational and environmental health professionals, other peers, and the public.
- A. manager
- B. researcher
- C. clinician/practitioner
- D. health promotion specialist
Correct answer: B
Rationale: The correct answer is 'B: researcher.' In this context, the individual is primarily involved in developing research questions, conducting research, and disseminating findings, which aligns with the responsibilities of a researcher. Choice 'A: manager' is incorrect because the role described does not primarily involve managerial duties. Choice 'C: clinician/practitioner' is also incorrect as the focus is on research activities rather than direct clinical practice. Choice 'D: health promotion specialist' does not encompass the full scope of responsibilities described in the scenario.
3. 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.
4. During the manic phase of bipolar disorder, what is the priority nursing intervention for a female client who has not slept for the past 48 hours, is hyperactive, talkative, and engaging in risky behaviors?
- A. Encourage the client to participate in a quiet activity.
- B. Provide a safe environment and limit stimuli.
- C. Administer a sedative to help the client sleep.
- D. Discuss the consequences of her risky behaviors.
Correct answer: B
Rationale: The correct priority nursing intervention for a female client in the manic phase of bipolar disorder, who has not slept for 48 hours, is hyperactive, talkative, and engaging in risky behaviors, is to provide a safe environment and limit stimuli. This approach is crucial to prevent harm to the client and others. Encouraging a quiet activity (Choice A) may not effectively address the need for safety during the manic phase. Administering a sedative (Choice C) should be done under the guidance of a healthcare provider and does not address the immediate safety concerns. Discussing consequences of risky behaviors (Choice D) may not be effective during the manic phase when the client's judgment is impaired.
5. The healthcare provider is evaluating the effectiveness of metaproterenol for how do you know it's been effective?
- A. Increased heart rate and blood pressure
- B. Decreased white blood cell count
- C. Decreased wheezing upon auscultation
- D. Decreased respiratory rate
Correct answer: C
Rationale: The effectiveness of metaproterenol, a bronchodilator, is assessed by a decrease in wheezing upon auscultation. Wheezing indicates airway constriction, and a reduction in wheezing signifies improved airflow and bronchodilation due to the medication's action. Therefore, choices A, B, and D are incorrect as they do not directly relate to the expected outcome of metaproterenol therapy.
