1. Which hormone, produced by the thyroid gland, plays a key role in regulating calcium levels in the blood by promoting calcium release from bones and increasing calcium reabsorption in the kidneys?

• A. Calcitonin
• B. Parathyroid hormone (PTH)
• C. Thyroxine
• D. Insulin

Correct answer: b

Rationale: The correct answer is B: Parathyroid hormone (PTH). PTH is produced by the parathyroid glands, not the thyroid gland. PTH plays a crucial role in regulating calcium levels in the blood by promoting calcium release from bones and increasing calcium reabsorption in the kidneys. This hormone acts in opposition to calcitonin, which is produced by the thyroid gland and works to lower blood calcium levels by promoting calcium deposition into bones. Thyroxine (C) is a thyroid hormone that regulates metabolism, not calcium levels. Insulin (D) is a hormone produced by the pancreas that regulates blood sugar levels, not calcium levels.

2. She plans of assigning competent people to fill the roles designed in the hierarchy. Which

• A. Staffing
• B. Scheduling
• C. Recruitment
• D. Induction

Correct answer: B

Rationale: The correct answer is B: Scheduling. Scheduling involves assigning people to specific tasks or roles within an organization based on the hierarchy and operational needs. In this scenario, the focus is on assigning competent individuals to fill the roles outlined in the hierarchy, which aligns with the concept of scheduling. Staffing refers to the overall process of acquiring, deploying, and retaining a workforce; recruitment specifically pertains to attracting and selecting candidates for job roles; and induction involves the orientation and integration of new employees into the organization. Therefore, the most relevant term in this context is scheduling.

3. What mineral is essential for muscle function and nerve transmission?

• A. Calcium
• B. Iron
• C. Sodium
• D. Potassium

Correct answer: A

Rationale: The correct answer is A: Calcium. Calcium is essential for muscle function and nerve transmission. Muscles require calcium to contract properly, and nerve cells use calcium ions to transmit signals throughout the body. Without an adequate amount of calcium, muscle cramps and nerve dysfunction can occur. Iron is important for oxygen transport in the blood, sodium and potassium are electrolytes important for fluid balance and nerve function, but they are not primarily responsible for muscle function and nerve transmission like calcium.

4. The epiglottis is a small flap of cartilage located near the base of the tongue. What is its role during swallowing?

• A. Initiates the swallowing reflex
• B. Grinds food into smaller pieces
• C. Covers the trachea to prevent food aspiration
• D. Stores saliva for lubrication

Correct answer: C

Rationale: The epiglottis is a crucial anatomical structure that covers the trachea during swallowing to prevent food aspiration. When we swallow, the epiglottis folds over the trachea, directing food and liquids down the esophagus instead of entering the airway. This action helps to ensure that the food and liquids go to the stomach for digestion and not into the lungs, which can lead to aspiration pneumonia, a serious condition. Therefore, option C, 'Covers the trachea to prevent food aspiration,' is the correct role of the epiglottis during swallowing.

5. Frequent, painful urination is a common symptom of:

• A. Diabetes
• B. Urinary tract infection (UTI)
• C. Kidney stones
• D. All of the above

Correct answer: D

Rationale: The correct answer is D, 'All of the above.' Frequent, painful urination can be a symptom of various conditions affecting the urinary system. In diabetes, high blood sugar levels can lead to increased urine production. UTIs often cause painful urination due to the infection in the urinary tract. Kidney stones can also result in frequent and painful urination as they obstruct the flow of urine. Therefore, all three options can present with the common symptom of frequent, painful urination, making 'All of the above' the correct choice.

6. She finds out that some managers have benevolent-authoritative style of management. Which

• A. Have condescending trust and confidence in their subordinates
• B. Gives economic or ego awards
• C. Communicates downward to the staff
• D. Allows decision making among subordinates

Correct answer: D

Rationale: The correct answer is D because the benevolent-authoritative style of management involves allowing decision-making among subordinates. This style combines a caring attitude towards employees with a level of authority and control. Managers who adopt this style often empower their subordinates to make decisions within a set framework, fostering a sense of autonomy and responsibility among the team. Options A, B, and C do not accurately describe the characteristics of a benevolent-authoritative management style, making them incorrect choices for this question.
