1. Which property of a wave represents the distance between two successive identical points on a wave?

• A. Wavelength
• B. Amplitude
• C. Frequency
• D. Period

Correct answer: a

Rationale: Wavelength is the distance between two identical points (like crests or troughs) on a wave.

2. Which term describes the resistance of a substance to being hammered into different shapes?

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

Correct answer: c

Rationale: Malleability refers to the resistance of a substance to being hammered or pressed into different shapes without breaking.

3. She conducts a 6-month performance review session with a staff member. Which of the

• A. She asks another nurse to attest the session as a witness.
• B. She informs the staff that she may ask another nurse to read the appraisal before the session is
• C. She tells the staff that the session is manager-centered.
• D. The session is private between the two members.

Correct answer: C

Rationale: Option C is the correct answer because telling the staff that the session is manager-centered indicates that the focus will be on the manager's evaluation and feedback rather than promoting a collaborative and transparent review process. This approach can lead to a one-sided assessment and may not foster open communication or growth opportunities for the staff member. Options A and B involve bringing in another nurse, which could potentially compromise the privacy and effectiveness of the performance review. Option D, stating that the session is private between the two members, does not address the issue of the session being manager-centered. Therefore, option C is the most appropriate choice to highlight the importance of a balanced and inclusive performance review process.

4. Which term describes the functional unit of a skeletal muscle responsible for muscle contraction?

• A. Myofibril
• B. Sarcomere
• C. Tendon
• D. Myoglobin

Correct answer: b

Rationale: The correct answer is B: Sarcomere. A sarcomere is the functional unit of a skeletal muscle responsible for muscle contraction. It is made up of overlapping filaments of actin and myosin proteins. Myofibrils are long, cylindrical structures within muscle cells that contain sarcomeres. Tendons are tough bands of fibrous connective tissue that connect muscles to bones and facilitate movement. Myoglobin is a protein found in muscle cells that stores oxygen for muscle use during exercise. Therefore, the sarcomere is specifically responsible for muscle contraction, making it the correct answer in this question.

5. What is the difference between mass and weight?

• A. Mass is the force exerted on an object due to gravity, whereas weight is the amount of matter in an object.
• B. Mass is a measure of inertia, whereas weight is a measure of the force of gravity acting on an object.
• C. Mass is measured in pounds, whereas weight is measured in kilograms.
• D. Mass is a vector quantity, whereas weight is a scalar quantity.

Correct answer: b

Rationale: Mass is the amount of matter in an object, while weight is the force exerted on an object due to gravity.

6. Which of the following is a unit of work and energy?

• A. Pascal (Pa)
• B. Kilowatt-hour (kWh)
• C. Coulomb (C)
• D. Tesla (T)

Correct answer: b

Rationale: Kilowatt-hour is a unit used to measure both work and energy, especially in the context of electricity consumption.
