1. Which of the following represents a form of potential energy?

• A. A moving car
• B. A spinning top
• C. A raised hammer
• D. A rolling ball

Correct answer: c

Rationale: A raised hammer possesses potential energy due to its elevated position relative to the ground.

2. Which element shares the same group (family) on the periodic table with helium (He)?

• A. Neon (Ne)
• B. Boron (B)
• C. Carbon (C)
• D. Oxygen (O)

Correct answer: A

Rationale: Neon (Ne). Both He and Ne belong to Group 18 (Noble Gases) due to their complete and stable outer electron shells.

3. The lymphatic system is primarily responsible for:

• A. Transporting nutrients throughout the body
• B. Removing excess fluids and waste products from tissues
• C. Producing red blood cells
• D. Regulating body temperature

Correct answer: B

Rationale: The correct answer is B: 'Removing excess fluids and waste products from tissues.' The lymphatic system plays a crucial role in maintaining fluid balance in the body by collecting excess interstitial fluid and returning it to the bloodstream. This system also helps in removing waste products, pathogens, and toxins from tissues, contributing to the body's immune response. Options A, C, and D are incorrect because transporting nutrients, producing red blood cells, and regulating body temperature are primarily the functions of other systems in the body such as the circulatory system, bone marrow, and the thermoregulatory system, respectively.

4. Passive transport does not require energy input from the cell. Which of the following is an example of passive transport?

• A. Active transport of ions across a membrane
• B. Diffusion of small molecules across a concentration gradient
• C. Movement of large molecules using vesicles
• D. Endocytosis of particles into the cell

Correct answer: D

Rationale: Passive transport refers to the movement of molecules across a cell membrane without the need for energy input. Endocytosis is an example of passive transport because it involves the cell engulfing particles or molecules from the external environment into vesicles without the direct expenditure of energy. On the other hand, options A, B, and C involve active processes that require energy. Active transport, such as the movement of ions against their concentration gradient, requires energy in the form of ATP. Diffusion of small molecules across a concentration gradient also does not require energy input, but it is a passive process, not active transport. Movement of large molecules using vesicles is a form of active transport called vesicular transport. Therefore, the correct answer is D, endocytosis of particles into the cell, as it exemplifies passive transport without the need for energy consumption by the cell.

5. 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.

6. What type of force opposes the motion of an object moving through a fluid (liquid or gas)?

• A. Gravitational force
• B. Tension force
• C. Viscous force
• D. Magnetic force

Correct answer: c

Rationale: Viscous force is the resistance experienced by an object moving through a fluid due to internal friction.
