1. A ball is thrown upwards. At the peak of its trajectory, which of the following forces is acting on the ball?

• A. Gravity only
• B. Gravity and air resistance only
• C. Neither gravity nor air resistance
• D. All of the above

Correct answer: C

Rationale: At the peak of its trajectory, the ball has momentarily stopped moving upwards and has not yet started to fall back down. Therefore, there is no longer a net force acting on the ball at that instant. Gravity is acting downwards, but since the ball is not moving, the force of gravity is balanced by an equal and opposite force, resulting in a net force of zero. Similarly, air resistance only affects the ball when it is in motion, so at the peak where the ball momentarily stops, there is no air resistance force. Therefore, at the peak of its trajectory, neither gravity nor air resistance is acting on the ball, making option C the correct answer.

2. What is the main reason why elements in Group 18 (Noble gases) are generally unreactive?

• A. They have high atomic masses
• B. They lack valence electrons
• C. Their outermost electron shells are completely filled
• D. They exist as single atoms, not molecules

Correct answer: C

Rationale: Noble gases have their outermost electron shells filled with 8 electrons, achieving a stable configuration with minimal urge to gain or lose electrons, making them less prone to chemical reactions.

3. Ms. Valencia develops the standards to be followed. Among the following standards, which is

• A. The patients verbalized satisfaction of the nursing care received
• B. Rotation of duty will be done every four weeks for all patient care personnel.
• C. All patients shall have their weights taken recorded
• D. Patients shall answer the evaluation form before discharge

Correct answer: C

Rationale: The correct answer is C because it is a clear and specific standard that can be easily measured and monitored. Weight recording is a fundamental aspect of patient care and is essential for tracking changes in health status. Verbalized satisfaction (option A) is subjective and may not be consistently measurable. Rotation of duty (option B) is important but may not be a standard developed by a nurse manager. Answering an evaluation form before discharge (option D) is important but may not be a standard created by Ms. Valencia for all patients.

4. A spring is stretched and released, causing an object attached to it to oscillate. What determines the frequency of the oscillations?

• A. The mass of the object
• B. The stiffness of the spring
• C. The initial displacement of the object
• D. All of the above

Correct answer: B

Rationale: The stiffness of the spring. Frequency depends on the spring constant and the mass, but the mass term cancels out in the formula for simple harmonic motion, leaving only the spring constant.

5. What is the myelin sheath and what does it do?

• A. A group of nerve cells that perform a specific function.
• B. A fatty substance that insulates some nerve fibers.
• C. A fluid-filled cavity within the brain.
• D. The junction between two neurons.

Correct answer: B

Rationale: The correct answer is B. The myelin sheath is a fatty substance that insulates some nerve fibers. It is essential for the proper functioning of the nervous system as it acts as an insulator, allowing for faster transmission of nerve impulses along the axon. Without the myelin sheath, nerve signals could be disrupted or weakened, leading to issues with movement, sensation, and other neurological functions. Options A, C, and D are incorrect as they do not accurately describe the myelin sheath or its function.

6. Her former manager demonstrated passion for serving her staff rather than being served. She

• A. Transformational leader
• B. Transactional leader
• C. Servant leader
• D. Charismatic leader

Correct answer: C

Rationale: The correct answer is C: 'Servant leader.' A servant leader prioritizes the needs of their team members, focusing on serving them rather than expecting to be served. This is evident in the scenario where the former manager showed passion for serving her staff. Servant leaders are known for their humility, empathy, and commitment to the growth and well-being of their team. This leadership approach fosters a positive work environment, builds trust, and promotes collaboration among team members.
