1. What do isotopes of the same element have in common?

• A. Identical number of protons and neutrons.
• B. Identical chemical properties.
• C. Identical number of electrons.
• D. Identical mass number.

Correct answer: A

Rationale: Identical number of protons and neutrons - Isotopes have the same atomic number but different mass numbers due to varying neutron counts.

2. A solution is 60% alcohol. If 200ml of the solution are used, how much pure alcohol is present?

• A. 100ml
• B. 120ml
• C. 140ml
• D. 160ml

Correct answer: C

Rationale: Multiply the total solution volume (200ml) by the alcohol percentage (60%)

3. Which of the following statements refers to criteria?

• A. Agreed on level of nursing care
• B. Characteristics used to measure the level of nursing care
• C. Step-by-step guidelines
• D. Statement which guide the group in decision making and problem solving

Correct answer: B

Rationale: Criteria are specific characteristics or standards used to evaluate or measure the quality or level of something. In this case, statement B, 'Characteristics used to measure the level of nursing care,' correctly refers to criteria because it highlights the specific attributes that are used to assess the quality or level of nursing care provided. The other options do not directly address the concept of criteria. Option A describes an agreed-upon level of care but does not specifically refer to criteria. Option C describes step-by-step guidelines, which are more related to processes or procedures. Option D mentions statements that guide decision-making and problem-solving, which are not necessarily criteria. Therefore, option B is the most appropriate choice as it directly aligns with the definition and concept of criteria.

4. What happens to the frequency of a wave if its wavelength decreases while the speed remains constant?

• A. Frequency decreases
• B. Frequency increases
• C. Frequency remains constant
• D. Frequency becomes zero

Correct answer: b

Rationale: If the speed of the wave remains constant while the wavelength decreases, the frequency of the wave increases.

5. A collection of organs working together to perform a specific physiological function is known as a(n):

• A. Tissue
• B. Organ system
• C. Organelle
• D. Organ

Correct answer: B

Rationale: The correct answer is B: Organ system. An organ system is a group of organs that work together to carry out a specific function in the body. While an organ is made up of different types of tissues that work together, an organ system involves multiple organs collaborating to perform more complex tasks. Tissues (option A) are groups of similar cells working together, organelles (option C) are structures within cells that have specific functions, and organs (option D) are made up of tissues and perform specific functions, but the term 'organ system' specifically refers to a higher level of organization involving multiple organs working in coordination.

6. What is the SI unit of measurement for work?

• A. Newton-meter (N·m)
• B. Joule (J)
• C. Watt (W)
• D. Meter per second (m/s)

Correct answer: b

Rationale: Work is measured in Joules (J) in the SI unit system.
