1. 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.

2. Which of the following is NOT a function of the integumentary system?

• A. Regulation of body temperature
• B. Protection from pathogens
• C. Synthesis of vitamin D
• D. Production of digestive enzymes

Correct answer: D

Rationale: The correct answer is D. The production of digestive enzymes is not a function of the integumentary system. The integumentary system is responsible for regulating body temperature, protecting the body from pathogens, and synthesizing vitamin D. Digestive enzymes are produced by organs in the digestive system, such as the pancreas and stomach, and not by the integumentary system.

3. 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.

4. Which of the following joints is an example of a hinge joint?

• A. Hip joint
• B. Elbow joint
• C. Shoulder joint
• D. Knee joint

Correct answer: B

Rationale: The correct answer is B: Elbow joint. A hinge joint allows movement primarily in one plane, enabling bending and straightening actions. The elbow joint specifically functions as a hinge joint, facilitating the bending and straightening of the arm. The other options, such as the hip joint (A), shoulder joint (C), and knee joint (D), are not examples of hinge joints as they allow movement in multiple planes with more complex motions.

5. What are substances that stimulate adaptive immunity called?

• A. Peptides
• B. Phagocytes
• C. Prions
• D. Platelets

Correct answer: A

Rationale: Substances that stimulate adaptive immunity are called peptides. Peptides are short chains of amino acids that play a crucial role in activating the immune response by interacting with immune cells such as T cells and B cells. Peptides are important in antigen presentation and recognition, leading to the development of specific immune responses against pathogens. Choice B, phagocytes, are cells that engulf and digest pathogens but are not substances that stimulate adaptive immunity. Choice C, prions, are infectious agents made of misfolded proteins and are not related to stimulating adaptive immunity. Choice D, platelets, are cell fragments involved in blood clotting and have no direct role in stimulating adaptive immunity.
