1. What type of reaction is represented by the following equation: Fe2O3 (s) + 3H2 (g) -> 2Fe (s) + 3H2O (g)

• A. Combustion
• B. Decomposition
• C. Single displacement
• D. Redox reaction

Correct answer: D

Rationale: The given equation involves a transfer of electrons from iron oxide (Fe2O3) to hydrogen gas (H2), resulting in the formation of iron (Fe) and water (H2O). This transfer of electrons indicates a redox reaction, where oxidation and reduction occur simultaneously. In this case, iron is reduced from a higher oxidation state in Fe2O3 to a lower oxidation state in Fe, while hydrogen is oxidized from its elemental state in H2 to form water. Therefore, the correct answer is D: Redox reaction.

2. Eliminate the function NOT attributed to the lymphatic system.

• A. Fluid drainage from tissues
• B. Immune response via white blood cell production
• C. Nutrient transport throughout the body
• D. Waste removal through lymph nodes

Correct answer: C

Rationale: Rationale: A) Fluid drainage from tissues: This function is attributed to the lymphatic system. Lymphatic vessels collect excess fluid from tissues and return it to the bloodstream. B) Immune response via white blood cell production: The lymphatic system plays a crucial role in the body's immune response by producing and transporting white blood cells, such as lymphocytes, which help fight infections. C) Nutrient transport throughout the body: Nutrient transport is primarily carried out by the circulatory system (blood vessels), not the lymphatic system. The circulatory system transports nutrients, oxygen, and hormones to cells and removes waste products. D) Waste removal through lymph nodes: The lymphatic system helps remove waste and toxins from the body by filtering lymph through lymph nodes, where harmful substances are trapped and destroyed by immune cells. Therefore, the function NOT attributed to the lymphatic system is C) Nutrient transport throughout the body.

3. Vacuoles are large sacs for storage in plant cells. What is their main function in animal cells?

• A. Protein synthesis
• B. Waste storage and disposal
• C. Photosynthesis
• D. Cellular respiration

Correct answer: B

Rationale: Vacuoles in plant cells are primarily used for storage of water, nutrients, and waste products. In animal cells, vacuoles are smaller and serve various functions, including waste storage and disposal. Option B, 'Waste storage and disposal,' is the correct answer because vacuoles in animal cells help maintain cellular homeostasis by storing and breaking down waste materials. This process aids in detoxification and maintaining proper cellular function in animal cells, similar to the role of vacuoles in plant cells.

4. The statement, “The Good Shepherd Medical Center aims to provide patient-centered care in

• A. Vision
• B. Goal
• C. Philosophy
• D. Mission

Correct answer: A

Rationale: The correct answer is A: "Vision." A vision statement describes the desired future state or long-term goal of an organization. It outlines the aspirations and purpose of the organization, such as providing patient-centered care in this case. Vision statements are forward-looking and inspirational, guiding the organization towards achieving its ultimate objectives. In contrast, a goal is a specific, measurable, and achievable target within a set timeframe. A philosophy is a set of beliefs or guiding principles, while a mission statement defines the organization's core purpose and focus. Therefore, the statement about providing patient-centered care aligns with the concept of a vision statement.

5. She surfs the internet for more information about leadership styles. She reads about shared

• A. Leadership behavior is generally determined by the relationship between the leader’s
• B. Leaders believe that people are basically good and need not be closely controlled
• C. Leaders rely heavily on visioning and inspire members to achieve results
• D. Leadership is shared at the point of care.

Correct answer: B

Rationale: The correct answer is B because the statement 'Leaders believe that people are basically good and need not be closely controlled' aligns with the concept of shared leadership. Shared leadership involves distributing leadership responsibilities and authority among team members based on the belief that everyone has valuable contributions to make. This approach fosters a sense of trust and empowerment within the team, allowing individuals to take initiative and collaborate effectively. In contrast, option A refers to leadership behavior being determined by the relationship between the leader and followers, which is not directly related to the concept of shared leadership. Option C emphasizes visioning and inspiration, which are important aspects of leadership but do not specifically address the shared nature of leadership. Option D mentions leadership being shared at the point of care, which is too specific and does not encompass the broader concept of shared leadership.

6. What is the relationship between the Pauli exclusion principle and the structure of the atom?

• A. It defines the maximum number of electrons allowed in each energy level.
• B. It explains why oppositely charged particles attract each other.
• C. It describes the wave-particle duality of electrons.
• D. It determines the arrangement of protons and neutrons in the nucleus.

Correct answer: A

Rationale: It defines the maximum number of electrons allowed in each energy level. The Pauli exclusion principle states that no two electrons in an atom can occupy the same quantum state, which explains the specific sequence and structure of electron shells within the atom.
