1. What is the name of the curved bone in the back that provides support and attachment for muscles?

• A. Sternum
• B. Scapula
• C. Clavicle
• D. Vertebral column

Correct answer: D

Rationale: The correct answer is D: Vertebral column. The vertebral column, also known as the spine or backbone, is a series of small bones called vertebrae that provide support and protection for the spinal cord. It also serves as an attachment point for various muscles in the back. The sternum, scapula, and clavicle are all bones in the upper body, but they do not specifically provide support and attachment for muscles in the back like the vertebral column does.

2. What type of enzyme breaks down carbohydrates like starches and sugars in the mouth?

• A. Pepsin
• B. Lipase
• C. Amylase
• D. Trypsin

Correct answer: C

Rationale: The correct answer is C: Amylase. Amylase is an enzyme specifically responsible for breaking down carbohydrates like starches and sugars in the mouth. It is produced by both the salivary glands and the pancreas. Pepsin (A) is an enzyme that breaks down proteins in the stomach, lipase (B) breaks down fats, and trypsin (D) is another enzyme that digests proteins but is produced in the pancreas and works in the small intestine. Therefore, amylase is the enzyme that targets carbohydrates in the mouth, aiding in the initial digestion process of these nutrients.

3. If 3 nurses can care for 15 patients, how many nurses are needed for 25 patients?

• A. 4
• B. 5
• C. 6
• D. 7

Correct answer: B

Rationale: 3 nurses / 15 patients = x nurses / 25 patients. Solve for x.

4. Which of the following represents a form of potential energy?

• A. A moving car
• B. A spinning top
• C. A raised hammer
• D. A rolling ball

Correct answer: c

Rationale: A raised hammer possesses potential energy due to its elevated position relative to the ground.

5. A medication dosage is listed as 1/4 gram. What is the equivalent dosage in milligrams (1 gram = 1000 milligrams)?

• A. 125mg
• B. 250mg
• C. 375mg
• D. 500mg

Correct answer: D

Rationale: Multiply the gram dosage (1/4) by the conversion factor (1000mg/gram) to get 250 milligrams.

6. What is the process by which a cell divides into two or more new cells?

• A. Mitosis
• B. Meiosis
• C. Both mitosis and meiosis
• D. None of the above

Correct answer: A

Rationale: Rationale: Mitosis is the process by which a cell divides into two identical daughter cells. This type of cell division is essential for growth, repair, and maintenance of multicellular organisms. Meiosis, on the other hand, is a type of cell division that produces gametes (sperm and egg cells) with half the number of chromosomes as the parent cell. Therefore, meiosis is not the process by which a cell divides into two or more new cells. Option C is incorrect because meiosis is not involved in the general process of cell division to produce new cells. Option D is incorrect because mitosis is the correct process for cell division.
