1. Testosterone is a crucial hormone in the male reproductive system. What is its primary function?

A. Egg production
B. Sperm production and development
C. Regulation of the menstrual cycle
D. Milk production

Correct answer: B

Rationale: The correct answer is B: Sperm production and development. Testosterone is a hormone primarily produced in the testes and is essential for the development of male reproductive tissues, including the testes and prostate. It plays a key role in the production of sperm cells (spermatogenesis) and the development of secondary sexual characteristics in males, such as facial hair and muscle mass. Testosterone is not involved in egg production (A), regulation of the menstrual cycle (C), or milk production (D) as these are functions associated with female reproductive hormones.

2. Which property of a substance measures the amount of matter per unit volume?

A. Density
B. Mass
C. Weight
D. Volume

Correct answer: a

Rationale: Density is the property that measures the amount of matter (mass) per unit volume of a substance. It is calculated as mass divided by volume.

3. What happens to the acceleration of an object when the force acting on it is increased, assuming the mass remains constant?

A. Acceleration increases
B. Acceleration decreases
C. Acceleration remains constant
D. Acceleration becomes zero

Correct answer: a

Rationale: According to Newton's second law (F = ma), if mass is constant and force increases, acceleration also increases.

4. What is the term for the shedding of the outermost layer of the epidermis?

A. Desquamation
B. Exfoliation
C. Keratinization
D. Epidermolysis

Correct answer: A

Rationale: The correct term for the shedding of the outermost layer of the epidermis is desquamation. Desquamation is a natural process where old skin cells are shed off to make way for new cells. Exfoliation refers to the removal of dead skin cells through external means like scrubs. Keratinization is the process by which skin cells produce the protein keratin, while epidermolysis is a condition where the epidermis separates from the dermis. Therefore, in this context, desquamation is the most appropriate term for the shedding of the outermost layer of the epidermis.

5. She knows that there are external forces that influence changes in his unit. Which of the

A. Memo from the CEO to cut down on electrical consumption
B. Demands of the labor sector to increase wages
C. Low morale of staff in her unit
D. Exacting regulatory and accreditation standards

Correct answer: A

Rationale: The correct answer is option A: 'Memo from the CEO to cut down on electrical consumption.' This choice represents an external force that can influence changes in the unit by setting a directive from top management to reduce electricity usage, impacting operations and decisions within the unit. While options B, C, and D may also affect the unit to some extent, they are not as directly tied to external influences as the CEO's memo. The demands of the labor sector (option B) and low staff morale (option C) are internal factors, while regulatory and accreditation standards (option D) are more overarching guidelines rather than specific external forces impacting the unit. Therefore, the most direct and relevant external force in this scenario is the directive from the CEO, making option A the correct choice.

6. Which of the following statements is NOT true about performance appraisal?

A. Informing the staff about the specific impressions of their work help improve their
B. A verbal appraisal is an acceptable substitute for a written report
C. Patients are the best source of information regarding personnel appraisal.
D. The outcome of performance appraisal rests primarily with the staff.

Correct answer: A

Rationale: Option A is the correct answer because informing staff about specific impressions of their work can be subjective and may not always lead to improvement. Performance appraisal should be based on objective criteria and feedback. Verbal appraisals can lack documentation and clarity, making a written report a more reliable form of evaluation. Patients may provide valuable input on staff interactions, but they may not have the full context to assess job performance comprehensively. The outcome of performance appraisal should involve both the staff and the appraiser, as it is a collaborative process to identify strengths and areas for development.
