1. What is the primary function of the liver?

• A. To produce bile, which aids in the digestion of fats
• B. To store energy in the form of glycogen
• C. To produce proteins that assist in blood clotting
• D. To detoxify harmful substances in the body

Correct answer: D

Rationale: The primary function of the liver is to detoxify harmful substances in the body. While the liver does produce bile to aid in the digestion of fats, this is not its primary function. Bile is stored in the gallbladder and released into the small intestine for fat digestion. Storing energy in the form of glycogen is a function of the liver, but not its primary one. Glycogen serves as a reserve of glucose. Although the liver produces proteins that assist in blood clotting, such as fibrinogen and prothrombin, this is not its main function. These proteins play a crucial role in blood clotting to prevent excessive bleeding. Therefore, the primary role of the liver is to detoxify harmful substances by processing and removing toxins, drugs, alcohol, and other harmful substances from the bloodstream, thereby reducing their harmful effects.

2. 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.

3. In which type of cell would you expect to find a high concentration of lysosomes?

• A. Cardiac cells
• B. Glandular cells
• C. Immune cells
• D. Neurons

Correct answer: C

Rationale: The correct answer is C: Immune cells. Immune cells, such as macrophages, contain many lysosomes for breaking down pathogens. Lysosomes are organelles responsible for digestion and waste removal within the cell, and immune cells require a high concentration of lysosomes to aid in their defense mechanisms against pathogens. Choice A, Cardiac cells, is incorrect because lysosomes are not primarily abundant in cardiac cells. Choice B, Glandular cells, is incorrect as well since lysosomes are not specifically concentrated in glandular cells. Choice D, Neurons, is also incorrect because while lysosomes are present in neurons, they are not typically found in high concentrations compared to immune cells.

4. Which term refers to a position toward the feet? For example, the foot is part of the inferior extremity.

• A. Anterior
• B. Posterior
• C. Superior
• D. Inferior

Correct answer: D

Rationale: The correct answer is 'Inferior.' 'Inferior' refers to a position located towards the feet or lower part of the body. This is the opposite of 'superior,' which indicates a position towards the head or upper part of the body. 'Anterior' refers to the front of the body, 'posterior' refers to the back of the body, making them incorrect choices in this context.

5. Which of the following glands produces hormones that regulate metabolism?

• A. Adrenal gland
• B. Pituitary gland
• C. Thyroid gland
• D. Liver

Correct answer: C

Rationale: The thyroid gland is responsible for producing hormones that play a crucial role in regulating metabolism. One of the key hormones produced by the thyroid gland is thyroxine, which directly influences the body's metabolic rate. Therefore, the correct answer is the thyroid gland. The adrenal gland produces hormones like adrenaline, which are associated with the stress response and not primarily metabolic regulation. The pituitary gland regulates various other hormones but is not primarily responsible for metabolic regulation. The liver has a role in metabolism, mainly in processes like detoxification and nutrient storage, but it is not a gland that primarily produces hormones for metabolic regulation, making it an incorrect choice in this context.
