1. What is the formula to calculate gravitational potential energy near the Earth's surface?

• A. Potential Energy=Mass×Acceleration
• B. Potential Energy=Force×Distance
• C. Potential Energy=Mass×Height×Gravity
• D. Potential Energy=Mass×Acceleration due to gravity×Height

Correct answer: d

Rationale: Gravitational potential energy near the Earth's surface is given by the formula PE = � × � × ℎ PE=m×g×h, where � m is mass, � g is acceleration due to gravity, and ℎ h is heigh

2. Which term describes the resistance of a substance to flow?

• A. Density
• B. Viscosity
• C. Conductivity
• D. Malleability

Correct answer: b

Rationale: Viscosity refers to the resistance of a substance to flow. Substances with high viscosity flow slowly, while those with low viscosity flow more easily.

3. On the other hand, Ms. Castro notices that the Chief Nurse Executive has charismatic

• A. Possesses inspirational quality that makes followers gets attracted of him and regards
• B. Acts as he does because he expects that his behavior will yield positive results
• C. Uses visioning as the core of his leadership
• D. Matches his leadership style to the situation at hand.

Correct answer: D

Rationale: The correct answer is D because matching leadership style to the situation at hand is a key aspect of effective leadership. Being able to adapt and adjust leadership approaches based on the specific circumstances and needs of a situation can lead to better outcomes and success. In this scenario, the Chief Nurse Executive's ability to tailor his leadership style to different situations is likely to contribute to his effectiveness in managing various challenges and leading the team effectively.

4. A spring with a spring constant of 100 N/m is stretched 0.2 m from its equilibrium position. What is the potential energy stored in the spring?

• A. 2 J
• B. 4 J
• C. 8 J
• D. 20 J

Correct answer: B

Rationale: Potential energy in a spring is calculated as 1/2 * k * x², where k is the spring constant and x is the displacement from equilibrium. Therefore, the potential energy is 1/2 * 100 N/m * (0.2 m)² = 4 J.

5. Which gland located in the neck is responsible for regulating metabolism, growth, and development?

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

Correct answer: B

Rationale: The correct answer is B: Thyroid gland. The thyroid gland is located in the neck and plays a crucial role in regulating metabolism, growth, and development. It produces hormones such as thyroxine (T4) and triiodothyronine (T3) that control the body's metabolic rate, affecting energy levels and growth. The parathyroid gland (A) regulates calcium levels in the body, the pituitary gland (C) controls several other glands and their hormone production, and the thymus gland (D) is involved in the immune system's development. Therefore, the thyroid gland is the most appropriate choice for the functions described in the question.

6. Which hormone, produced by the adrenal glands, plays a crucial role in the body's response to stress, including the regulation of salt and water balance?

• 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 the body's response to stress by regulating salt and water balance. It acts on the kidneys to increase the reabsorption of sodium and water, helping to maintain blood pressure and electrolyte balance during times of stress. Epinephrine and cortisol are also stress hormones produced by the adrenal glands, but they have different functions. Epinephrine is involved in the fight-or-flight response, while cortisol helps regulate metabolism and immune function. Insulin, produced by the pancreas, is involved in glucose metabolism and not directly related to the body's stress response. Therefore, aldosterone is the most appropriate hormone in this context.
