Nursing Elites

1. Which conjunction best joins the following sentence: "She loves animals, ____ she volunteers at the shelter."

• A. because
• B. therefore
• C. so
• D. and

Correct answer: D

Rationale: "And" simply adds information about her love for animals without implying cause or effect.

2. Which of the following is TRUE about functional nursing?

• A. Concentrates on tasks and activities
• B. Emphasizes use of group collaboration
• C. One-to-one nurse-patient ratio
• D. Provides continuous, coordinated and comprehensive nursing services

Correct answer: B

Rationale: The correct answer is B: "Emphasizes use of group collaboration." Functional nursing is a task-oriented approach where team members specialize in specific tasks or activities. In this model, nurses work together in groups to provide care to a larger number of patients efficiently. This differs from the one-to-one nurse-patient ratio (C) and the continuous, coordinated, and comprehensive nursing services (D). While functional nursing concentrates on tasks (A), the key feature emphasized in this care delivery model is the use of group collaboration to provide care effectively.

3. The fundamental units of structure and function in all living organisms, including humans, are termed:

• A. Muscles
• B. Organs
• C. Tissues
• D. Cells

Correct answer: D

Rationale: The correct answer is D: Cells. Cells are the fundamental units of structure and function in all living organisms, including humans. They are the building blocks of life, performing various functions necessary for an organism to survive and thrive. Muscles (A) are composed of muscle tissue, which is made up of muscle cells. Organs (B) are structures made up of different types of tissues working together. Tissues (C) are groups of cells that work together to perform specific functions within an organism. However, cells are the smallest unit of life and are responsible for carrying out all the essential processes needed for an organism to function.

4. What type of molecule forms the cell membrane and controls what enters and exits the cell?

• A. Proteins
• B. Carbohydrates
• C. Lipids
• D. Nucleic acids

Correct answer: C

Rationale: The correct answer is C: Lipids. The cell membrane is primarily composed of a double layer of lipids called phospholipids. These phospholipids have a hydrophilic (water-attracting) head and two hydrophobic (water-repelling) tails, which arrange themselves to form a barrier that controls the passage of substances in and out of the cell. While proteins are also present in the cell membrane and play important roles in transport and cell signaling, lipids are the main structural component responsible for the selective permeability of the membrane. Carbohydrates are typically found on the outer surface of the membrane and are involved in cell recognition and communication. Nucleic acids are not a major component of the cell membrane; they are primarily responsible for storing and transmitting genetic information within the cell.

5. Which of the following is NOT a characteristic of mitosis?

• A. The replication of DNA
• B. The condensation of chromosomes
• C. The separation of sister chromatids
• D. The formation of haploid cells

Correct answer: D

Rationale: Rationale: A) The replication of DNA is a characteristic of mitosis. Before cell division occurs, the DNA is replicated to ensure that each daughter cell receives a complete set of genetic information. B) The condensation of chromosomes is a characteristic of mitosis. During mitosis, the chromosomes condense and become visible under a microscope as distinct structures. C) The separation of sister chromatids is a crucial step in mitosis. During anaphase, the sister chromatids are pulled apart and move to opposite poles of the cell to ensure that each daughter cell receives a complete set of chromosomes. D) The formation of haploid cells is NOT a characteristic of mitosis. Mitosis results in the formation of two identical diploid daughter cells, each containing the same number of chromosomes as the parent cell. Haploid cells are typically formed through the process of meiosis, not mitosis.

6. 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.
