1. What is the term for a group of organisms that can interbreed and produce fertile offspring?

• A. Genus
• B. Phylum
• C. Kingdom
• D. Species

Correct answer: D

Rationale: Rationale: A species is defined as a group of organisms that can interbreed and produce fertile offspring. This ability to interbreed and produce fertile offspring is a key characteristic that distinguishes one species from another. In contrast, a genus (option A) is a taxonomic rank that includes one or more species that are closely related, while a phylum (option B) and a kingdom (option C) are higher taxonomic ranks that encompass multiple species.

2. Functional nursing has some advantages, which one is an EXCEPTION?

• A. Psychological and sociological needs are emphasized.
• B. Great control of work activities.
• C. Most economical way of delivering nursing services.
• D. Workers feel secure in dependent role

Correct answer: B

Rationale: Functional nursing is a task-oriented approach where each nurse is assigned specific duties, leading to efficient task completion but often resulting in a lack of holistic care. While functional nursing may provide great control over work activities and can be cost-effective due to specialization, it does not emphasize psychological and sociological needs, which is a significant disadvantage. Additionally, the dependent role that workers feel in functional nursing can lead to disempowerment and hinder professional growth and autonomy. Therefore, option A, 'Psychological and sociological needs are emphasized,' is the exception among the advantages of functional nursing.

3. Simplify the expression: -5 + (-8)

• A. -13
• B. 8
• C. 13
• D. -5

Correct answer: A

Rationale: Combine the negative signs by adding them together. -5 + (-8) = -13

4. When ice melts, it undergoes a…

• A. Chemical change
• B. Physical change
• C. Nuclear change
• D. Radioactive decay

Correct answer: B

Rationale: Melting is a change in physical state, not a change in the chemical composition of the ice.

5. Which term refers to the measure of the mass of a substance per unit volume and is commonly expressed in kilograms per cubic meter?

• A. Mass
• B. Weight
• C. Density
• D. Volume

Correct answer: c

Rationale: Density is the measure of the mass of a substance per unit volume and is commonly expressed in kilograms per cubic meter (kg/m³).

6. Saliva contains an enzyme that breaks down carbohydrates. What is the name of this enzyme?

• A. Pepsin
• B. Amylase
• C. Lipase
• D. Trypsin

Correct answer: B

Rationale: The correct answer is B: Amylase. Saliva contains the enzyme amylase, which is responsible for breaking down carbohydrates into simpler sugars like maltose and glucose. Pepsin (A) is an enzyme found in the stomach that breaks down proteins. Lipase (C) is an enzyme that breaks down fats, and trypsin (D) is another enzyme that breaks down proteins, but both of these are not found in saliva. Knowing the function of amylase in saliva helps in the digestion of carbohydrates, making it the correct answer.
