1. She decides to illustrate the organizational structure. Which of the following elements is

• A. Level of authority
• B. Lines of communication
• C. Span of control
• D. Unity of direction

Correct answer: D

Rationale: The correct answer is D, 'Unity of direction.' In the context of illustrating organizational structure, unity of direction refers to the concept that activities within an organization should be directed towards a common goal. It ensures that all efforts are aligned and coordinated towards achieving the organization's objectives. This element helps in avoiding conflicts and confusion by providing clarity and focus on the overall mission of the organization, which is essential for effective organizational performance. Level of authority, lines of communication, and span of control are important elements in organizational structure as well, but in this scenario, unity of direction specifically pertains to the coordination and alignment of activities towards a common purpose.

2. When light interacts with a perfectly smooth surface, like a mirror, the dominant interaction is:

• A. Refraction
• B. Diffraction
• C. Total internal reflection
• D. Specular reflection

Correct answer: D

Rationale: The correct answer is D: Specular reflection. When light interacts with a perfectly smooth surface like a mirror, it undergoes specular reflection, where the light rays are reflected at the same angle as the incident angle. Refraction (option A) occurs when light passes from one medium to another at an angle, causing it to change direction. Diffraction (option B) is the bending of light waves around obstacles or through small openings. Total internal reflection (option C) occurs when light traveling in a medium strikes the boundary with another medium at an angle greater than the critical angle, causing the light to reflect back into the original medium. In the case of a perfectly smooth surface, specular reflection is the dominant interaction as the light rays reflect in a single direction with minimal scattering or diffraction.

3. Which element is used in fire extinguishers to smother flames by displacing oxygen?

• A. Nitrogen
• B. Carbon dioxide
• C. Helium
• D. Argon

Correct answer: B

Rationale: Carbon dioxide extinguishes flames by depriving them of oxygen, preventing the chemical reaction that sustains the fire.

4. What happens to the work done on an object when the angle between force and displacement is 90 degrees?

• A. Maximum work is done
• B. No work is done
• C. Minimum work is done
• D. Work is infinite

Correct answer: b

Rationale: When the angle between force and displacement is 90 degrees, the work done on the object is zero.

5. St. Raphael Medical Center just opened its new Performance Improvement Department. Ms.

• A. Make an interpretation about strengths and weaknesses
• B. Identify the values of the department
• C. Identify structure, process, outcome standards & criteria
• D. Measure actual performances

Correct answer: B

Rationale: The correct answer is B: 'Identify the values of the department.' When a new department is established, it is important to define its core values, beliefs, and principles to guide its operations. This helps create a shared understanding among staff and stakeholders about the department's purpose and priorities. By identifying the values of the Performance Improvement Department at St. Raphael Medical Center, employees can align their actions with the department's mission and goals, fostering a cohesive and effective work environment. Options A, C, and D are not directly related to establishing the foundational values of a new department, making them less relevant in this context.

6. What is the main function of the endoplasmic reticulum (ER) in the cell?

• A. To synthesize and transport proteins and lipids
• B. To package and transport proteins
• C. To break down macromolecules
• D. To store genetic material

Correct answer: A

Rationale: Rationale: A) The endoplasmic reticulum (ER) is a network of membranes within the cell that plays a crucial role in protein and lipid synthesis. It consists of two types: rough ER, which is studded with ribosomes and involved in protein synthesis, and smooth ER, which is involved in lipid synthesis and detoxification. The ER also plays a role in transporting these synthesized proteins and lipids to other parts of the cell or outside the cell. B) While the ER is involved in packaging proteins, the main function is not solely to package and transport proteins. This function is more associated with the Golgi apparatus. C) Breaking down macromolecules is primarily the function of lysosomes, which are membrane-bound organelles containing enzymes for digestion. D) Storing genetic material is the function of the nucleus, which houses the cell's DNA. The ER is not involved in storing
