1. Define the term "velocity" in relation to motion.

• A. Speed in a specific direction
• B. Distance traveled in a given time
• C. Rate of change of position
• D. Acceleration due to gravity

Correct answer:

Rationale: Velocity is the rate of change of position concerning direction, unlike speed which only refers to distance traveled per unit time.

2. The transfer of energy through feeding relationships in an ecosystem is called a:

• A. Food Chain
• B. Food Web
• C. Habitat
• D. Biome

Correct answer: A

Rationale: Rationale: A food chain is a linear sequence of organisms where each organism consumes the one below it and is consumed by the one above it. This transfer of energy through feeding relationships is a fundamental concept in ecology to understand how energy flows through an ecosystem. In a food chain, energy is transferred from producers (plants) to primary consumers (herbivores), then to secondary consumers (carnivores), and so on. Each step in the food chain represents a trophic level, and energy is lost as heat at each level, resulting in a pyramid-shaped energy flow. Food webs, on the other hand, represent a more complex network of interconnected food chains within an ecosystem. Habitats refer to the specific environment where an organism lives, and biomes are large geographical areas characterized by specific climate and vegetation types.

3. Which of the following is the best guarantee that the patient’s priority needs are met?

• A. Checking with the relative of the patient
• B. Preparing a nursing care plan in collaboration with the patient
• C. Consulting with the physician
• D. Coordinating with other members of the team

Correct answer: B

Rationale: Preparing a nursing care plan in collaboration with the patient is the best guarantee that the patient's priority needs are met because it involves actively involving the patient in their own care. This approach ensures that the patient's preferences, concerns, and priorities are taken into account when planning their care. Checking with the relative of the patient, consulting with the physician, and coordinating with other team members are important aspects of patient care, but collaborating with the patient directly ensures a patient-centered approach that addresses their individual needs and preferences.

4. What happens to the gravitational potential energy of an object as it falls freely?

• A. It decreases
• B. It increases
• C. It remains constant
• D. It becomes zero

Correct answer: a

Rationale: Gravitational potential energy decreases as an object falls freely due to a decrease in its height.

5. Which sentence uses strong verbs to create a more vivid image?

• A. The car moved slowly down the street.
• B. The car drove sluggishly down the road.
• C. The car inched down the avenue.
• D. The car traveled down the thoroughfare.

Correct answer: C

Rationale: "Inched" creates a stronger image of the car's slow movement compared to "moved" or "drove."

6. What is the name for the balanced equation that represents a chemical reaction?

• A. Hypothesis
• B. Chemical formula
• C. Balanced equation
• D. Reaction mechanism

Correct answer: C

Rationale: A balanced equation shows the reactants, products, and their stoichiometric coefficients, ensuring equal numbers of atoms of each element on both sides.
