1. A researcher wants to conduct qualitative research. Which method should they use?

• A. Collecting patient narratives
• B. Tracking the dosage of a drug and its blood levels in the patient
• C. Observing a patient's physical changes
• D. Writing journal notes about the research experience

Correct answer: A

Rationale: Qualitative research focuses on gathering non-numerical, descriptive data to explore experiences, behaviors, or perspectives. Collecting patient narratives aligns with qualitative research as it involves capturing detailed accounts of individuals' experiences or viewpoints. Choices B, C, and D involve more quantitative approaches by focusing on measurable quantities, observations, or structured note-taking, which are not characteristic of qualitative research methods.

2. What is the definition of power in physics?

• A. The rate of change of energy
• B. The rate of doing work or transferring energy
• C. The measure of an object's potential energy
• D. The force exerted on an object

Correct answer: B

Rationale: The correct answer is B: 'The rate of doing work or transferring energy.' Power in physics is defined as the rate at which work is done or energy is transferred. It is a measure of how quickly energy is transferred or converted. Power is not the same as energy itself but rather how fast energy is being transferred or converted. Choice A, 'The rate of change of energy,' is incorrect because power is about the rate of work or energy transfer, not just the change in energy. Choice C, 'The measure of an object's potential energy,' is incorrect as power is not a measure of potential energy but rather the rate of energy transfer. Choice D, 'The force exerted on an object,' is incorrect as power is related to work and energy transfer, not just force exerted.

3. What is the term used to describe the inability of the kidneys to effectively filter waste products from the blood?

• A. Dehydration
• B. Kidney failure
• C. Incontinence
• D. Nephritis

Correct answer: B

Rationale: Kidney failure is the term used to describe the inability of the kidneys to effectively filter waste products from the blood. Dehydration refers to insufficient fluid intake and not the kidney's filtering function. Incontinence is the loss of bladder control, not related to kidney filtration. Nephritis is the inflammation of the kidneys, not specifically related to the kidneys' inability to filter waste products.

4. In a study evaluating which type of road salt deices a road most quickly, what is the independent variable?

• A. Deicing time period
• B. Road used for deicing
• C. Type of road salt used
• D. Amount of road salt used

Correct answer: C

Rationale: The correct answer is C, 'Type of road salt used.' In an experiment, the independent variable is the one manipulated by the researcher to observe its impact on the dependent variable. In this study, the researchers are altering the type of road salt used to determine its influence on the deicing speed, thus making it the independent variable. The other choices are not the independent variable as they are not deliberately manipulated in the experiment: A - 'Deicing time period' is an outcome measure dependent on the type of salt used; B - 'Road used for deicing' is not controlled or manipulated; D - 'Amount of road salt used' would be a potential confounding variable rather than the independent variable as it could affect the outcome along with the type of salt.

5. What type of immunity is acquired through vaccination?

• A. Passive natural immunity
• B. Active natural immunity
• C. Active artificial immunity
• D. Passive artificial immunity

Correct answer: C

Rationale: The correct answer is C, Active artificial immunity. Vaccination introduces a weakened or inactive form of the pathogen to stimulate the immune system, leading to the development of immunity. Active artificial immunity is the result of deliberate exposure to an antigen, such as through vaccination, to produce an immune response. Passive immunity, like receiving pre-formed antibodies, does not involve the immune system's activation. Natural immunity is typically acquired through exposure to the pathogen itself, not through vaccination.
