1. What is the name of the microscopic finger-like projections that increase the surface area for absorption in the small intestine?

• A. Goblet cells
• B. Paneth cells
• C. Villi
• D. Crypts of Lieberkühn

Correct answer: C

Rationale: Rationale: A) Goblet cells: Goblet cells are specialized cells that secrete mucus to protect the lining of the digestive tract. While important for maintaining the health of the intestines, goblet cells do not increase the surface area for absorption in the small intestine. B) Paneth cells: Paneth cells are specialized cells found in the small intestine that secrete antimicrobial peptides. They play a role in protecting the intestinal stem cells and maintaining the gut microbiota balance, but they do not increase the surface area for absorption. C) Villi: Villi are microscopic finger-like projections found in the small intestine that increase the surface area available for absorption of nutrients. Each villus contains blood vessels and lacteals (lymphatic vessels) that help absorb nutrients from digested food. D) Crypts of Lieberkühn: Crypts of Lieberkühn are small pits located between the villi

2. He discusses the goal of the department. Which of the following statements is a goal?

• A. Increase the patient satisfaction rate
• B. Eliminate the incidence of delayed administration of medications
• C. Establish rapport with patients.
• D. Reduce response time to two minutes.

Correct answer: A

Rationale: Option A, 'Increase the patient satisfaction rate,' is a goal because it represents an objective that the department aims to achieve. Patient satisfaction is a key indicator of quality care and reflects the department's commitment to providing excellent service. In contrast, options B, C, and D are more focused on specific actions or strategies rather than overarching goals. Eliminating delayed medication administration, establishing rapport with patients, and reducing response time are important tasks that may contribute to achieving the goal of increasing patient satisfaction, but they are not goals in themselves. Therefore, option A is the most appropriate choice as it directly addresses the department's ultimate objective of enhancing patient satisfaction.

3. Why are isotopes of the same element chemically similar?

• A. They have the same number of protons.
• B. They have the same number of electrons.
• C. Their chemical properties are identical.
• D. They share the same electron configuration.

Correct answer: A

Rationale: They have the same number of protons. This determines the element's identity and its interactions with other elements, leading to similar chemical behavior, even if the number of neutrons differs.

4. Two coherent light waves with a slight phase difference interfere. What determines the resulting intensity of the combined wave?

• A. The individual intensities of the waves
• B. The wavelength of the waves
• C. The distance between the waves
• D. The color of the waves

Correct answer: A

Rationale: The intensity of the resulting wave depends on the individual intensities and the phase difference between the interfering waves. Constructive interference leads to higher intensity, while destructive interference leads to lower intensity.

5. Warming up before exercise is important to help prevent

• A. Dehydration
• B. Muscle soreness
• C. Increased heart rate
• D. Low blood sugar

Correct answer: B

Rationale: The correct answer is B: 'Muscle soreness.' Warming up before exercise is crucial as it helps increase blood flow to the muscles, warming them up and making them more flexible. This can help reduce the risk of muscle soreness and injury during and after exercise. Dehydration (A) is more related to maintaining proper fluid balance through hydration. Increased heart rate (C) is a normal response to exercise and can be beneficial. Low blood sugar (D) is more of a concern for individuals with conditions like diabetes. Therefore, the most immediate benefit of warming up is to prevent muscle soreness.

6. What happens to the concentration of hydrogen ions (\([H^+]\)) in a solution as the pH increases?

• A. Increases
• B. Decreases
• C. Remains constant
• D. Becomes neutral

Correct answer: B

Rationale: As the pH increases, the concentration of hydrogen ions decreases. The relationship is inversely proportional
