Nursing Leadership and Management
1. She decides to have a decentralized staffing system. Which of the following is an advantage
- A. greater control of activities
- B. Conserves time
- C. Compatible with computerization
- D. Promotes better interpersonal relationship
Correct answer: A
Rationale: The correct answer is A: 'greater control of activities.' Having a decentralized staffing system allows for the delegation of decision-making to lower levels of the organization, which can result in greater control over activities. This can lead to quicker responses to issues and better alignment with specific departmental needs. Options B, C, and D do not directly relate to the advantage of a decentralized staffing system. While conserving time, compatibility with computerization, and promoting better interpersonal relationships are important considerations in staffing decisions, they do not specifically align with the advantage of greater control that a decentralized system provides.
2. The author likely intended to use the phrase "interconnected sensors" to emphasize...
- A. The cost-effectiveness of smart city technology.
- B. The complexity and network-based nature of the system.
- C. The potential for environmental harm of sensor installation.
- D. The aesthetic appeal of modern urban infrastructure.
Correct answer: B
Rationale: "Interconnected" highlights the integration and communication between sensors, indicating a complex network approach.
3. What is the least common multiple (LCM) of 4 and 6?
- A. 24
- B. 12
- C. 6
- D. 3
Correct answer: B
Rationale: The LCM is the smallest number that is a multiple of both 4 and 6. We can find this by listing out the multiples of each number until we find a common value. In this case, 12 is the first number divisible by both 4 (4 x 3) and 6 (6 x 2).
4. How is power related to time?
- A. Power is inversely proportional to time
- B. Power is directly proportional to time
- C. Power is unrelated to time
- D. Power is the product of time and work
Correct answer: c
Rationale: Power is the rate at which work is done or energy is transferred, and it is not directly linked to time.
5. Which term refers to the resistance of a liquid to flow?
- A. Density
- B. Viscosity
- C. Surface tension
- D. Boiling point
Correct answer: B
Rationale: Viscosity is the term that refers to the resistance of a liquid to flow. It is a measure of how thick or sticky a fluid is, and it determines how easily a liquid can flow. Density (A) is a measure of how much mass is contained in a given volume, surface tension (C) is the property of a liquid that allows it to resist an external force due to the cohesive nature of its molecules, and boiling point (D) is the temperature at which a liquid changes to a vapor.
6. What is the purpose of the spindle apparatus in cell division?
- A. To separate sister chromatids
- B. To move chromosomes to opposite poles of the cell
- C. To form a new nuclear envelope around each daughter cell
- D. To synthesize new DNA
Correct answer: B
Rationale: Rationale: The spindle apparatus is a structure composed of microtubules that plays a crucial role in cell division (mitosis and meiosis). Its main purpose is to ensure the proper separation and distribution of chromosomes to opposite poles of the cell during cell division. This process is essential for the formation of two genetically identical daughter cells in mitosis or four haploid daughter cells in meiosis. Option A is incorrect because the separation of sister chromatids specifically refers to the role of the kinetochore fibers within the spindle apparatus. Option C is incorrect because the formation of a new nuclear envelope occurs after the chromosomes have been properly segregated. Option D is incorrect because DNA synthesis does not occur within the spindle apparatus; it takes place during the S phase of the cell cycle.
