1. What is the process of changing from a liquid to a gas called?

• A. Freezing
• B. Condensation
• C. Vaporization
• D. Sublimation

Correct answer: C

Rationale: The correct answer is C: Vaporization. Vaporization is the process by which a substance changes from a liquid state to a gas state. Choice A, Freezing, is incorrect as it refers to the process of changing from a liquid to a solid. Choice B, Condensation, is incorrect as it describes the process of changing from a gas to a liquid. Choice D, Sublimation, is incorrect as it involves changing directly from a solid to a gas without passing through the liquid state.

2. What is the normal (complete) flow of blood through the heart?

• A. Right atrium → lungs → left atrium → body
• B. Left atrium → left ventricle → body → right atrium
• C. Right atrium → right ventricle → lungs → left atrium → left ventricle → aorta → body
• D. Right ventricle → left ventricle → body

Correct answer: C

Rationale: The correct flow of blood through the heart starts with the right atrium receiving deoxygenated blood from the body, followed by the right ventricle pumping blood to the lungs for oxygenation. Oxygenated blood then returns to the heart through the left atrium, then passes to the left ventricle which pumps it out to the body through the aorta. This flow ensures that blood is properly oxygenated before circulating through the body. Choice A is incorrect as the blood does not go directly from the left atrium to the body, skipping the left ventricle. Choice B is incorrect as it does not follow the correct flow sequence in the heart. Choice D is incorrect as it does not include the full pathway of blood through the heart.

3. As a nursing student triaging a patient, which of the following is an example of quantitative data you can gather?

• A. The patient says he feels pain.
• B. The patient says he has stabbing pain.
• C. The patient's temperature is 101.7°F.
• D. The patient reports that he had a fever yesterday.

Correct answer: C

Rationale: The corrected choice C, 'The patient's temperature is 101.7°F,' is an example of quantitative data because it provides a specific numerical value that can be measured. Quantitative data involves measurable and numerical information, making it crucial for assessing a patient's condition objectively. Choices A and B are subjective statements based on the patient's perception of pain and its description, which are qualitative data and may vary between individuals. Choice D provides historical information about a fever, which is not a current measurable value and does not constitute quantitative data for immediate assessment.

4. What is the most basic unit of structure in living things?

• A. Cell
• B. Organelle
• C. Oxygen
• D. Pigment

Correct answer: A

Rationale: The cell is indeed the most basic unit of life, forming the foundation of all living organisms. Cells are the building blocks of all living things, containing organelles that perform specific functions. While oxygen is essential for life, it is not a structural unit. Similarly, pigment is a component found within cells but is not the fundamental unit of structure. Therefore, the correct answer is 'A: Cell.'

5. What is the initial step of the scientific method?

• A. construct a hypothesis
• B. make observations
• C. analyze data
• D. form a question

Correct answer: B

Rationale: The first step of the scientific method is to make observations. This involves collecting data and information about a specific phenomenon or problem. Observations serve as the basis for developing a question to be explored further. Forming a hypothesis (Choice A) comes after making observations, as the hypothesis is an educated guess to explain the observations. Analyzing data (Choice C) occurs later in the scientific method after data has been collected and experiments conducted. Forming a question (Choice D) is a crucial step but typically follows observations in the scientific process.
