1. What is the product of the complete combustion of propane (C3H8)?

• A. CO2
• B. CO
• C. CH4
• D. C

Correct answer: a

Rationale: Complete combustion of hydrocarbons produces carbon dioxide (CO2) and water.

2. Identify the preposition in the following sentence: The cat jumped over the fence.

• A. cat
• B. jumped
• C. over
• D. the

Correct answer: C

Rationale: Prepositions show the relationship between a noun or pronoun and another word in the sentence. "Over" indicates the position of the cat in relation to the fence.

3. What describes the change in direction of light when it passes through different mediums, such as air and water?

• A. Diffraction
• B. Reflection
• C. Refraction
• D. Dispersion

Correct answer: c

Rationale: Refraction is the bending of light as it passes from one medium to another with different optical densities, causing a change in direction.

4. Which structure in the respiratory system is responsible for the exchange of oxygen and carbon dioxide between the lungs and the bloodstream?

• A. Trachea
• B. Bronchi
• C. Alveoli
• D. Bronchioles

Correct answer: C

Rationale: The correct answer is C, Alveoli. Alveoli are tiny air sacs located at the end of the bronchioles in the lungs where the exchange of oxygen and carbon dioxide takes place. Oxygen from the air we breathe diffuses into the bloodstream through the alveoli walls, while carbon dioxide from the bloodstream diffuses into the alveoli to be exhaled. The trachea and bronchi are responsible for carrying air to and from the lungs, while bronchioles are small air passages within the lungs that branch off from the bronchi. However, the actual gas exchange occurs in the alveoli, making them crucial for the respiratory system's function.

5. Which type of joint allows for the most movement?

• A. Ball-and-socket joint (shoulder)
• B. Hinge joint (elbow)
• C. Fibrocartilaginous joint (wrists)
• D. Suture joint (skull)

Correct answer: A

Rationale: The correct answer is A: Ball-and-socket joint (shoulder). Ball-and-socket joints allow for the most movement in all directions, such as flexion, extension, abduction, adduction, and rotation. The shoulder joint is a prime example, as it enables a wide range of motion, allowing the arm to move in multiple planes. Hinge joints, like the elbow, primarily allow movement in one direction (flexion and extension). Fibrocartilaginous joints, such as those in the wrists, have limited movement due to the presence of cartilage between the bones. Suture joints, found in the skull, are immovable joints that provide structural support rather than movement. Therefore, ball-and-socket joints like the shoulder joint offer the greatest range of motion among the options provided.

6. 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.
