Chemistry

1. What is the term for a solution that has exactly the same concentration of solute as another solution?

Correct answer: c

Rationale: An isotonic solution has the same concentration of solute as another solution. The other choices do not accurately describe an isotonic solution.

2. A set of integers can be classified as positive, negative, or zero. Which of the following statements about multiplying positive and negative integers is ALWAYS true?

Correct answer: B

Rationale: Rationale: When multiplying a positive integer by a negative integer, the product will always be negative. This is a fundamental rule of arithmetic. The sign of the product is determined by the rule that states that a positive number multiplied by a negative number results in a negative number. Therefore, the statement that the product will always be negative is always true when multiplying positive and negative integers.

3. A patient's height is 1.65 meters and their weight is 75kg. Calculate their BMI and interpret the result.

Correct answer: C

Rationale: Divide weight (75kg) by height squared (1.65m^2) to get BMI (27.7). This falls within the "overweight" category (25-29.9 BMI).

4. What is the main target organ for insulin, the hormone produced by the pancreas?

Correct answer: C

Rationale: The correct answer is C: Muscles. Insulin is a hormone produced by the pancreas that plays a crucial role in regulating blood sugar levels. Its main target organs are the liver, muscles, and adipose tissue. Insulin acts on muscle cells to promote glucose uptake and storage as glycogen, helping to lower blood sugar levels. While the liver and adipose tissue are also important targets for insulin, muscles are particularly significant for glucose utilization and storage. Therefore, muscles are considered the main target organ for insulin in the body.

5. As a manager, she focuses her energy on both the quality of services rendered to the patients

Correct answer: B

Rationale: The correct answer is 'B: Organization man management.' This type of management focuses on maintaining the efficiency and structure of an organization. In this scenario, the manager's emphasis on the quality of services aligns with the principles of organization man management, which prioritizes the coordination of tasks and resources to achieve optimal results within the organization. This contrasts with 'Country club management,' which emphasizes employee satisfaction over task accomplishment; 'Team management,' which focuses on collaboration and teamwork; and 'Authority-obedience management,' which centers on strict hierarchical control. Therefore, the most appropriate choice is 'B: Organization man management.'

6. What is the process of cells restoring damaged or lost tissues called?

Correct answer: D

Rationale: Rationale: A) Cell division refers to the process by which a cell divides into two daughter cells. B) Cell differentiation is the process by which cells become specialized for specific functions. C) Cell growth is the increase in cell size or number. D) Cell regeneration is the process of cells restoring damaged or lost tissues by replacing or repairing the damaged cells. This process is essential for healing wounds and maintaining tissue integrity.
