• A. Organizational structure

It serves as a valuable resource for new hires to understand the standard operating procedures and expectations within the hospital setting, making it a crucial document to reference during orientation.

4. Which vitamin is known to play a vital role in immune function?

• A. Vitamin A
• B. Vitamin B12
• C. Vitamin D
• D. Vitamin E

Correct answer: D

Rationale: The correct answer is Vitamin D. Vitamin D is known to play a vital role in immune function as it helps regulate the immune system's response to infections and reduces inflammation. It is involved in the production of antimicrobial peptides that help fight off pathogens. Vitamin A is important for vision and skin health, Vitamin B12 is essential for red blood cell formation and neurological function, and Vitamin E is an antioxidant that protects cells from damage. However, Vitamin D specifically stands out for its crucial role in supporting the immune system, making it the correct answer in this context.

5. What is the protective fluid that surrounds the brain and spinal cord?

• A. Blood
• B. Cerebrospinal fluid
• C. Myelin sheath
• D. Insulin

Correct answer: B

Rationale: The correct answer is B: Cerebrospinal fluid. This fluid acts as a cushion for the brain and spinal cord, providing protection from impacts. Blood is essential for transporting nutrients and oxygen, but it does not directly surround or protect these vital nervous system structures. Myelin sheath is a fatty substance that insulates nerve fibers, not the fluid surrounding the nervous system. Insulin is a hormone involved in regulating blood sugar levels and is not related to protecting the brain and spinal cord.

6. The outermost layer of your skin, responsible for waterproofing and providing a barrier against pathogens, is the:

• A. Stratum basale (Basal layer)
• B. Stratum corneum
• C. Stratum granulosum
• D. Stratum spinosum

Correct answer: B

Rationale: The correct answer is B: Stratum corneum. The stratum corneum is the outermost layer of the epidermis, consisting of dead skin cells (corneocytes) that are continuously shed and replaced. This layer is responsible for waterproofing the skin and providing a barrier against pathogens, UV radiation, and other environmental factors. The stratum basale (A) is the deepest layer of the epidermis where new skin cells are produced. The stratum granulosum (C) is the layer of the epidermis where cells begin to flatten and keratinization begins. The stratum spinosum (D) is the layer above the stratum granulosum, where cells become interconnected by desmosomes. Therefore, the stratum corneum is specifically designed to fulfill the functions of waterproofing and protecting against pathogens.
