1. What is the relationship between the speed of a wave, its frequency, and wavelength in a given medium?

• A. Speed = Frequency × Wavelength
• B. Speed = Frequency ÷ Wavelength
• C. Speed = Frequency + Wavelength
• D. Speed = Frequency - Wavelength

Correct answer: a

Rationale: In a given medium, the speed of a wave equals the product of its frequency and wavelength.

2. Which structure in the respiratory system serves as a passageway for both air and food, with a flap-like structure that prevents food from entering the trachea during swallowing?

• A. Larynx
• B. Pharynx
• C. Trachea
• D. Bronchi

Correct answer: B

Rationale: The correct answer is B: Pharynx. The pharynx is a structure in the respiratory system that serves as a passageway for both air and food. It has a flap-like structure called the epiglottis, which prevents food from entering the trachea during swallowing. The larynx is commonly known as the voice box and is responsible for sound production. The trachea is a tube that carries air to and from the lungs, and the bronchi are the two main branches that lead from the trachea to the lungs. Therefore, the pharynx is the correct answer as it specifically fits the description provided in the question.

3. He asserts the importance of promoting a positive organizational culture in their unit. Which

• A. Proactive and caring with one another
• B. Competitive and perfectionist
• C. Powerful and oppositional
• D. Obedient and uncomplaining

Correct answer: A

Rationale: The correct answer is A: 'Proactive and caring with one another.' When promoting a positive organizational culture, it is essential to foster a supportive environment where individuals are proactive in their approach and demonstrate care towards one another. This type of culture encourages collaboration, open communication, and empathy among team members, leading to higher levels of job satisfaction and overall performance. Being competitive and perfectionist (option B) can create a stressful and unhealthy work environment, while being powerful and oppositional (option C) or obedient and uncomplaining (option D) can stifle creativity and innovation. Therefore, the most suitable traits for promoting a positive organizational culture are being proactive and caring with one another.

4. In a food chain, which trophic level captures energy from the sun?

• A. Decomposers
• B. Carnivores
• C. Producers
• D. Omnivores

Correct answer: C

Rationale: Rationale: Producers, such as plants, algae, and some bacteria, are the organisms in a food chain that capture energy from the sun through the process of photosynthesis. They convert sunlight into chemical energy, which is then passed on to other organisms in the food chain. Producers are at the base of the food chain and form the foundation for all other trophic levels to obtain energy. Decomposers (option A) break down organic matter, carnivores (option B) consume other animals, and omnivores (option D) consume both plants and animals, but they do not directly capture energy from the sun.

5. When she presents the nursing procedures to be followed, she refers to what type of

• A. Process
• B. Outcome
• C. Structure
• D. Criteria

Correct answer: D

Rationale: In this scenario, the person is referring to the specific standards or benchmarks that must be met when presenting nursing procedures, which aligns with the definition of 'criteria'. Criteria are the established principles or requirements that serve as a reference point for evaluation or judgment. It is essential for healthcare professionals to adhere to specific criteria when performing procedures to ensure quality care. The other options, such as 'process', 'outcome', and 'structure', do not directly relate to the standards or benchmarks being referenced in this context.

6. What term describes the bending of waves around obstacles or through openings?

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

Correct answer: c

Rationale: Diffraction occurs when waves bend around obstacles or spread after passing through small openings.
