1. Which form of energy is associated with the motion of an object?

• A. Kinetic energy
• B. Potential energy
• C. Thermal energy
• D. Electrical energy

Correct answer: a

Rationale: Kinetic energy is the energy of motion possessed by an object.

2. What is the term for a hydrocarbon chain with no double or triple bonds between carbon atoms?

• A. Saturated
• B. Unsaturated
• C. Aromatic
• D. Alkene

Correct answer: A

Rationale: A saturated hydrocarbon chain has only single bonds between carbon atoms. The other choices are associated with unsaturation or aromaticity.

3. After discussing the possible effects of the low patient satisfaction rate, the staff started to list

• A. Collaboration
• B. Majority rule
• C. Dominance
• D. Compromise

Correct answer: B

Rationale: The correct answer is B: 'Majority rule.' In this scenario, the staff is likely listing potential solutions or actions based on the opinion or agreement of the majority. Collaboration (A) involves working together towards a common goal, while Dominance (C) implies one person or group having control. Compromise (D) suggests finding a middle ground between different viewpoints. Majority rule best fits the situation where a decision or list of actions is being determined by what most people agree on, which is a common approach in group decision-making processes.

4. What is the medical term for heartburn, a burning sensation in the chest caused by stomach acid?

• A. Dysphagia
• B. Gastroesophageal reflux disease (GERD)
• C. Peptic ulcer
• D. Ulcerative colitis

Correct answer: B

Rationale: Rationale: A) Dysphagia refers to difficulty swallowing and is not specifically related to heartburn. B) Gastroesophageal reflux disease (GERD) is the medical term for heartburn, which is a burning sensation in the chest caused by stomach acid flowing back up into the esophagus. C) Peptic ulcer is a sore that develops on the lining of the stomach, small intestine, or esophagus, and it can cause symptoms such as abdominal pain, not specifically heartburn. D) Ulcerative colitis is a type of inflammatory bowel disease that affects the colon and rectum, and it does not typically cause heartburn.

5. Which of the following is the main organ responsible for absorbing nutrients?

• A. Stomach
• B. Small intestine
• C. Large intestine
• D. Pancreas

Correct answer: B

Rationale: Rationale: The small intestine is the main organ responsible for absorbing nutrients from the food we eat. It is where the majority of digestion and absorption of nutrients such as carbohydrates, proteins, fats, vitamins, and minerals occurs. The inner lining of the small intestine is covered in tiny finger-like projections called villi, which increase the surface area available for nutrient absorption. The stomach plays a role in breaking down food into smaller particles, but the actual absorption of nutrients primarily takes place in the small intestine. The large intestine mainly absorbs water and electrolytes, while the pancreas produces digestive enzymes and hormones but is not primarily responsible for absorbing nutrients.

6. Which type of glial cell provides structural support and insulation for neurons in the central nervous system?

• A. Schwann cells
• B. Astrocytes
• C. Oligodendrocytes
• D. Microglia

Correct answer: C

Rationale: The correct answer is C: Oligodendrocytes. Oligodendrocytes are a type of glial cell found in the central nervous system that provide structural support and insulation for neurons by forming myelin sheaths around axons. Schwann cells, on the other hand, are found in the peripheral nervous system. Astrocytes play a role in nutrient transfer and maintaining the blood-brain barrier. Microglia are responsible for immune defense and clearing debris in the CNS. Therefore, oligodendrocytes are specifically responsible for providing structural support and insulation for neurons in the central nervous system.
