Chemistry
1. An element with atomic number 26 and mass number 56 is most likely to be:
- A. Iron (Fe)
- B. Cobalt (Co)
- C. Nickel (Ni)
- D. Manganese (Mn)
Correct answer: A
Rationale: Iron (Fe) - Fe-56 has 26 protons and aligns with the given atomic number and mass number.
2. What are enzymes?
- A. Building blocks of muscle
- B. Biological catalysts
- C. Energy source
- D. Antibodies
Correct answer: B
Rationale: Enzymes are proteins that speed up chemical reactions in our cells. They act like tiny factories, fitting specific molecules (substrates) into their active site to facilitate reactions.
3. A car is traveling at a constant speed on a straight road. What is the net force acting on the car?
- A. A force equal to its weight pushing upwards
- B. A force equal to its weight pushing downwards
- C. A force equal to its engine power pushing forward
- D. No net force
Correct answer: D
Rationale: Since the car's speed is constant, there is no acceleration, and according to Newton's first law, a net force of zero is required.
4. Which of the following statements about fungi is FALSE?
- A. They can be unicellular or multicellular
- B. They are all parasitic and cause disease in humans
- C. They play a vital role in decomposition and nutrient cycling
- D. Some are used in food production, like mushrooms
Correct answer: B
Rationale: Rationale: A) This statement is true. Fungi can exist in both unicellular (yeast) and multicellular (molds and mushrooms) forms. B) This statement is false. While some fungi can be parasitic and cause diseases in humans, not all fungi exhibit this behavior. Many fungi are beneficial and play essential roles in ecosystems. C) This statement is true. Fungi are crucial for decomposition and nutrient cycling in ecosystems. They break down organic matter and recycle nutrients back into the environment. D) This statement is true. Some fungi, like mushrooms, are used in food production and are consumed by humans.
5. The thymus gland, crucial for immune system development, is located in the:
- A. Chest
- B. Abdomen
- C. Pelvis
- D. Head and neck
Correct answer: A
Rationale: The thymus gland, an essential organ for immune system development, is located in the chest region, specifically in the upper part of the chest behind the breastbone. It plays a vital role in the maturation of T-cells, a type of white blood cell crucial for immune responses. The thymus gland is part of the lymphatic system and is most active during childhood and adolescence, gradually decreasing in size and function with age. Its location in the chest allows it to interact closely with other immune system components in the body, making it a key player in maintaining overall immune health.
6. 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.
