1. Which of the following blood vessels carries oxygenated blood away from the lungs?

• A. Pulmonary artery
• B. Aorta
• C. Superior vena cava
• D. Inferior vena cava

Correct answer: B

Rationale: The correct answer is B: Aorta. The aorta is the main artery in the body that carries oxygenated blood away from the heart to the rest of the body. The pulmonary artery, option A, carries deoxygenated blood from the heart to the lungs for oxygenation. The superior vena cava, option C, and inferior vena cava, option D, are veins that carry deoxygenated blood from the upper and lower parts of the body, respectively, back to the heart. Therefore, the aorta is the blood vessel that carries oxygenated blood away from the lungs.

2. He wants to influence the customary way of thinking and behaving that is shared by the

• A. Organizational chart
• B. Cultural network
• C. Organizational structure
• D. Organizational culture

Correct answer: A

Rationale: The correct answer is A: "Organizational chart." In the context of the question, the individual is aiming to impact the established patterns of thinking and behavior within a group or organization. An organizational chart typically depicts the formal structure of an organization, including roles, relationships, and reporting lines. By influencing the organizational chart, the individual can potentially shape the hierarchical structure and decision-making processes, thereby impacting the customary way of thinking and behaving within the organization. Options B, C, and D do not directly refer to the visual representation of roles and relationships within an organization, making them incorrect choices for this question.

3. A playground fence has a rectangular section (5m by 3m) attached to a semicircular section with a radius of 2m. What is the total perimeter?

• A. 13m
• B. 16m
• C. 19m
• D. 22m

Correct answer: D

Rationale: Calculate the semicircle perimeter (π * radius) and add it to the rectangular perimeter: perimeter = π * radius + 2 (length + width) ≈ 3.14 * 2m + 2 (5m + 3m) ≈ 6.28m + 16m ≈ 22.28m ≈ 22m (rounded).

4. Which muscular pouch in the upper left abdomen stores food after swallowing and begins mechanical and chemical digestion?

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

Correct answer: B

Rationale: The correct answer is B: Stomach. The stomach is the muscular pouch in the upper left abdomen that stores food after swallowing. It is responsible for beginning both mechanical and chemical digestion processes. Once food enters the stomach, it is mixed with gastric juices and enzymes that break down the food into smaller particles. The stomach also contracts and relaxes to further mix the food with digestive juices. The esophagus is a tube that connects the throat to the stomach and does not store food or participate in digestion. The small intestine and large intestine are parts of the digestive system, but they are not muscular pouches in the upper left abdomen responsible for storing and digesting food.

5. The process of mixing two or more substances to form a heterogeneous mixture is called:

• A. Dissolving
• B. Diluting
• C. Mixing
• D. Reacting

Correct answer: C

Rationale: Mixing results in a heterogeneous mixture where the components are physically distinguishable, unlike solutions where everything dissolves uniformly

6. Which of the following is TRUE about functional nursing?

• A. Concentrates on tasks and activities
• B. Emphasizes use of group collaboration
• C. One-to-one nurse-patient ratio
• D. Provides continuous, coordinated and comprehensive nursing services

Correct answer: B

Rationale: The correct answer is B: "Emphasizes use of group collaboration." Functional nursing is a task-oriented approach where team members specialize in specific tasks or activities. In this model, nurses work together in groups to provide care to a larger number of patients efficiently. This differs from the one-to-one nurse-patient ratio (C) and the continuous, coordinated, and comprehensive nursing services (D). While functional nursing concentrates on tasks (A), the key feature emphasized in this care delivery model is the use of group collaboration to provide care effectively.
