1. Stephanie is a new Staff Educator of a private tertiary hospital. She conducts orientation

• A. Organizational structure
• B. Policy
• C. Job description
• D. Manual of procedures

Correct answer: D

Rationale: The correct answer is D, 'Manual of procedures.' During orientation, Stephanie as a Staff Educator would likely refer to the manual of procedures to provide new employees with detailed instructions on how to perform their job duties. This manual outlines the specific procedures, protocols, and guidelines that employees are expected to follow within the organization. It serves as a valuable resource for new hires to understand the standard operating procedures and expectations within the hospital setting, making it a crucial document to reference during orientation.

2. Antiparticles possess properties opposite to their corresponding particles. Which of the following is the antiparticle of a neutron?

• A. Antineutrino
• B. Positron
• C. Antiproton
• D. Electron

Correct answer: A

Rationale: The correct answer is A: Antineutrino. Antiparticles possess properties that are opposite to their corresponding particles. A neutron is a neutral subatomic particle found in the nucleus of an atom. Its antiparticle, the antineutrino, has opposite properties, such as having no electric charge compared to the neutron's neutral charge. A positron (B) is the antiparticle of an electron, an antiproton (C) is the antiparticle of a proton, and an electron (D) is not an antiparticle. Therefore, the antiparticle of a neutron is the antineutrino.

3. The following epithelium lines the inner surface of the oral cavity, providing a barrier against external insults. Which type of epithelium best fits this description?

• A. Simple squamous epithelium
• B. Stratified squamous epithelium
• C. Simple columnar epithelium
• D. Pseudostratified columnar epithelium

Correct answer: B

Rationale: The correct answer is B: Stratified squamous epithelium. The oral cavity is subjected to mechanical stress and potential injuries from chewing and abrasive food particles. Stratified squamous epithelium is the best choice for this location due to its multiple layers of cells that provide protection against wear and tear. This type of epithelium is well-suited for areas that require a tough, protective barrier, making it ideal for lining the oral cavity. In contrast, simple squamous epithelium is a single layer of flat cells found in locations where filtration or diffusion occurs, not where protection is needed. Simple columnar epithelium and pseudostratified columnar epithelium are better suited for absorption and secretion functions in areas like the intestines and respiratory tract, respectively.

4. What is the difference between a pure substance and a mixture?

• A. Pure substances have fixed composition, mixtures don't.
• B. Mixtures have fixed composition, pure substances don't
• C. Pure substances are always solids, mixtures can be any state
• D. Pure substances are always elements, mixtures are always compounds

Correct answer: A

Rationale: Rationale: - Pure substances have a definite and constant composition, meaning they are made up of only one type of atom or molecule. This composition does not vary. - Mixtures, on the other hand, are composed of two or more substances physically combined. The components of a mixture can be present in varying proportions, leading to a variable composition. - Option A correctly distinguishes between pure substances and mixtures based on the fixed composition of pure substances and the variable composition of mixtures.

5. A car is traveling on a curved road. What force keeps the car moving along the curved path?

• A. Gravitational force
• B. Normal force from the road
• C. Air resistance
• D. Friction between the tires and the road

Correct answer: D

Rationale: In this case, static friction acts between the tires and the road, providing the centripetal force required to keep the car moving in a circle even though it's traveling in a straight line relative to the ground.

6. What is the main difference between a nuclear reactor and a nuclear bomb?

• A. Reactors use enriched uranium, while bombs use natural uranium.
• B. Reactors have controlled chain reactions, while bombs have uncontrolled chain reactions.
• C. Reactors generate electricity, while bombs cause explosions.
• D. Reactors use moderators, while bombs don't.

Correct answer: B

Rationale: The key difference lies in the control of the fission chain reaction. Reactors have controlled reactions for energy generation, while bombs have rapid, uncontrolled reactions creating explosions.
