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 muscular tube that connects the outer surface to the cervix in a woman's birth canal referred to as?

• A. The uterus
• B. The cervix
• C. The vagina
• D. The ovaries

Correct answer: C

Rationale: The correct answer is C, 'The vagina.' The muscular tube that connects the outer surface to the cervix in a woman's birth canal is called the vagina. The vagina serves as the passageway for menstrual flow, sexual intercourse, and childbirth. The cervix, not the uterus, connects the vagina to the uterus. The ovaries, on the other hand, are the organs responsible for producing eggs and female hormones, but they are not the muscular tube connecting the outer surface to the cervix in the birth canal.

3. Which structure in the eye is responsible for detecting light?

• A. Cornea
• B. Retina
• C. Lens
• D. Iris

Correct answer: B

Rationale: The retina is the correct answer as it is the light-sensitive structure in the eye that detects light and converts it into signals for the brain to process visual information. The cornea is the transparent outer covering of the eye that helps to focus incoming light onto the lens. The lens further focuses the light onto the retina, which is where the actual light detection and signal conversion occur. The iris, on the other hand, controls the amount of light entering the eye by adjusting the size of the pupil but is not directly responsible for detecting light.

4. What is the primary function of the lymphatic system?

• A. Transporting nutrients throughout the body
• B. Removing excess fluids and waste products from tissues
• C. Producing red blood cells
• D. Regulating body temperature

Correct answer: B

Rationale: The primary function of the lymphatic system is to remove excess fluids, waste products, and toxins from tissues. It maintains fluid balance and supports the immune system by transporting lymph, which contains white blood cells, throughout the body. Choice A is incorrect as nutrient transport is primarily handled by the circulatory system. Choice C is incorrect because red blood cells are produced in the bone marrow, not the lymphatic system. Choice D is incorrect as the regulation of body temperature is mainly controlled by the endocrine system and thermoregulatory mechanisms in the body. Therefore, the correct answer is B.

5. What does potency refer to in regards to cells?

• A. The cell's ability to survive
• B. The cell's ability to move
• C. The cell's ability to divide rapidly
• D. The cell's ability to differentiate

Correct answer: D

Rationale: Potency refers to a cell's potential to differentiate into different cell types. It is not related to the cell's ability to survive (Choice A), move (Choice B), or divide rapidly (Choice C). Stem cells, for example, exhibit varying degrees of potency based on their capacity to give rise to various cell types. Therefore, the correct answer is D as it accurately defines the concept of potency in cells.
