1. Which hormone, produced by the adrenal glands, is essential for the regulation of electrolyte balance, particularly sodium and potassium, in the body?

• A. Aldosterone
• B. Epinephrine
• C. Cortisol
• D. Insulin

Correct answer: A

Rationale: The correct answer is A: Aldosterone. Aldosterone is a hormone produced by the adrenal glands that plays a crucial role in regulating electrolyte balance, especially sodium and potassium levels in the body. It acts on the kidneys to increase the reabsorption of sodium and excretion of potassium, which helps to maintain proper fluid balance and blood pressure. Epinephrine (B) is involved in the 'fight or flight' response, cortisol (C) is a stress hormone, and insulin (D) regulates blood sugar levels, but neither of these hormones primarily regulates electrolyte balance like aldosterone does.

2. Ms. Castro learns that some leaders are transactional leaders. Which of the following does

• A. Focuses on management tasks
• B. Is a caretaker
• C. Uses trade-offs to meet goals
• D. Inspires others with vision

Correct answer: C

Rationale: The correct answer is C: 'Uses trade-offs to meet goals.' Transactional leaders focus on the exchange or transaction that occurs between them and their followers. They set clear expectations and goals for their followers and use rewards and punishments to motivate them. This approach involves making trade-offs to achieve desired outcomes, such as rewarding employees for meeting targets or penalizing them for not meeting expectations. Options A and B do not directly relate to transactional leadership, as it is more about goal achievement and motivation through rewards and punishments. Option D describes a transformational leader, who inspires and motivates others through a shared vision and values, which is different from the transactional leadership style described in the question.

3. What is the term for a solution that has a higher concentration of solute compared to another solution?

• A. Saturated solution
• B. Unsaturated solution
• C. Dilute solution
• D. Concentrated solution

Rationale: A concentrated solution has a higher concentration of solute compared to another solution. The other choices do not accurately describe a concentrated solution.

4. What is the name for the mixture of reactants and products present during a chemical reaction?

• A. Solution
• B. Mixture
• C. Reaction mixture
• D. Precipitate

Rationale: This mixture contains both the starting materials (reactants) and the newly formed substances (products) during the reaction process.

5. The statement, “The Good Shepherd Medical Center aims to provide patient-centered care in

• A. Vision
• B. Goal
• C. Philosophy
• D. Mission

Correct answer: A

Rationale: The correct answer is A: "Vision." A vision statement describes the desired future state or long-term goal of an organization. It outlines the aspirations and purpose of the organization, such as providing patient-centered care in this case. Vision statements are forward-looking and inspirational, guiding the organization towards achieving its ultimate objectives. In contrast, a goal is a specific, measurable, and achievable target within a set timeframe. A philosophy is a set of beliefs or guiding principles, while a mission statement defines the organization's core purpose and focus. Therefore, the statement about providing patient-centered care aligns with the concept of a vision statement.
