1. Julius orients his staff on the patterns of reporting relationship throughout the organization.

• A. Span of control
• B. Hierarchy
• C. Esprit d’ corps
• D. Unity of direction

Correct answer: B

Rationale: The correct answer is B: Hierarchy. Hierarchy refers to the structure of authority and responsibility within an organization, including the levels of management and the reporting relationships. In this scenario, Julius is orienting his staff on the patterns of reporting relationships, which is a key aspect of hierarchy. Span of control refers to the number of employees a manager can effectively supervise, esprit de corps pertains to team spirit and unity among employees, and unity of direction relates to ensuring all activities are focused on the same objectives. Therefore, the most appropriate term for Julius's action is hierarchy.

2. What is the involuntary process of emptying the bladder called?

• A. Filtration
• B. Micturition
• C. Reabsorption
• D. Excretion

Correct answer: B

Rationale: The correct answer is B: 'Micturition.' Micturition, also known as urination, is the involuntary process of emptying the bladder. During micturition, the bladder contracts while the sphincter muscles relax, allowing urine to be expelled from the body. Filtration (A) is the process of separating substances based on their size as they pass through a filter. Reabsorption (C) refers to the process of reclaiming substances from the filtrate in the renal tubules back into the bloodstream. Excretion (D) is the process of eliminating waste products from the body through urine, feces, sweat, or other means. Therefore, micturition is the specific term that describes the act of emptying the bladder involuntarily.

3. Negative feedback mechanisms are crucial in the endocrine system to:

• A. Increase hormone production continuously
• B. Maintain hormone levels within a specific range
• C. Cause a constant release of hormones
• D. Disrupt communication between glands

Correct answer: B

Rationale: The correct answer is B: 'Maintain hormone levels within a specific range.' Negative feedback mechanisms in the endocrine system are essential for regulating hormone levels. These mechanisms work to counteract any deviations from the set point, ensuring that hormone levels remain balanced and within the optimal range for proper physiological function. Continuous hormone production (A) or constant release of hormones (C) would lead to imbalances and potential harm to the body. Disrupting communication between glands (D) would hinder the coordination necessary for maintaining homeostasis. Therefore, option B is the best choice as it highlights the critical role of negative feedback in keeping hormone levels stable and regulated.

4. Acne vulgaris, commonly known as acne, is primarily caused by

• A. Dry skin (Dry skin can worsen acne but isn't the primary cause)
• B. Clogged pores and excess oil production
• C. Bacterial infection alone (Bacteria play a role but not the sole cause)
• D. Vitamin deficiency

Correct answer: B

Rationale: The correct answer is B: 'Clogged pores and excess oil production.' Acne vulgaris, or acne, is primarily caused by a combination of factors including excess sebum (oil) production by the skin's sebaceous glands and the accumulation of dead skin cells, leading to clogged pores. This environment provides a breeding ground for acne-causing bacteria, contributing to inflammation and the formation of pimples. While factors like dry skin, bacterial infections, and even vitamin deficiencies can exacerbate acne, they are not the primary cause. Thus, B is the most accurate option for the primary cause of acne.

5. Calcitonin, a hormone that helps regulate calcium levels, is produced by the:

• A. Thyroid gland
• B. Parathyroid gland
• C. Thymus gland
• D. Adrenal gland

Correct answer: A

Rationale: The correct answer is A: "Thyroid gland." Calcitonin is a hormone produced by the thyroid gland that helps regulate calcium levels in the body. It works in opposition to parathyroid hormone, which is produced by the parathyroid gland. The thymus gland is responsible for immune function, while the adrenal gland produces hormones like cortisol and adrenaline. Therefore, the thyroid gland is the specific gland responsible for producing calcitonin to regulate calcium levels in the body.

6. Ms. Valencia is responsible to the number of personnel reporting to her. This principle refers

• A. Span of control
• B. Unity of command
• C. Carrot and stick principle
• D. Esprit d’ corp

Correct answer: B

Rationale: The correct answer is B: Unity of command. Unity of command is a fundamental principle of management stating that each employee should receive orders from only one supervisor to avoid confusion and ensure clarity in the chain of command. In this scenario, Ms. Valencia's responsibility for the number of personnel reporting to her aligns with the concept of unity of command. Span of control refers to the number of subordinates a supervisor can efficiently manage, while the carrot and stick principle involves motivating employees through rewards and punishments. Esprit d’ corp refers to the sense of unity and camaraderie within a group.
