Nursing Leadership and Management
1. The following are basic steps in the controlling process of the department. Which of the
- A. Measure actual performance
- B. Set nursing standards and criteria
- C. Compare results of performance to standards and objectives
- D. Identify possible courses of action
Correct answer: A
Rationale: The correct answer is A: 'Measure actual performance.' In the controlling process of a department, measuring actual performance is a crucial step to assess how well the department is performing compared to set standards and objectives. By measuring actual performance, managers can identify any deviations from the established criteria and take necessary corrective actions. Setting nursing standards and criteria (option B) is typically done before the controlling process begins, to provide a benchmark for measuring performance. Comparing results of performance to standards and objectives (option C) is done after measuring actual performance. Identifying possible courses of action (option D) is part of the corrective action phase that follows measuring actual performance. Therefore, option A is the most appropriate step in the controlling process of a department.
2. What is the term for the phenomenon when two waves combine to form a new wave?
- A. Diffraction
- B. Interference
- C. Refraction
- D. Dispersion
Correct answer: b
Rationale: Interference occurs when two waves meet and their amplitudes combine, resulting in a new wave.
3. A decorative box has a rectangular base (20cm by 15cm) and a hemispherical top with the same diameter as the base. What is the total surface area of the box (excluding the base)?
- A. 825 sq cm
- B. 1075 sq cm
- C. 1325 sq cm
- D. 1575 sq cm
Correct answer: C
Rationale: Calculate the surface area of the lateral sides and the hemisphere, then add them up.
4. What is the main difference between white and brown adipose tissue?
- A. Location only
- B. Function and energy metabolism
- C. Color only
- D. Both white and brown have the same function
Correct answer: B
Rationale: The main difference between white and brown adipose tissue lies in their function and energy metabolism. White adipose tissue is primarily involved in energy storage, while brown adipose tissue is responsible for energy expenditure through thermogenesis. Brown adipose tissue contains a higher density of mitochondria and a unique protein called uncoupling protein 1 (UCP1) that allows for the generation of heat. This key distinction in function and energy metabolism sets white and brown adipose tissue apart, making option B the correct answer.
5. Which technique best helps maintain consistency in writing style?
- A. Writing freely without a clear outline or structure.
- B. Using different vocabulary and sentence structures in each paragraph.
- C. Establishing a style guide with agreed-upon terminology and formatting.
- D. Relying on thesaurus suggestions for varied word choices.
Correct answer: C
Rationale: A style guide ensures consistency in tone, terminology, and formatting across different pieces of writing.
6. Sebaceous glands, located in the dermis, secrete an oily substance called:
- A. Sweat
- B. Sebum
- C. Cerumen
- D. Mucus
Correct answer: B
Rationale: The correct answer is B: Sebum. Sebaceous glands are located in the dermis layer of the skin and are responsible for producing sebum, an oily substance that helps lubricate and waterproof the skin and hair. Sweat glands, on the other hand, are located in the dermis and subcutaneous layers and produce sweat to help regulate body temperature. Cerumen is produced by ceruminous glands in the ear canal to protect the ear, while mucus is produced by mucous glands in the respiratory system to help trap and remove particles. Therefore, sebum is the oily substance secreted by sebaceous glands in the dermis.
