1. Edema is a condition characterized by swelling caused by a buildup of lymph fluid. What factors can contribute to edema?

• A. Regular exercise
• B. Maintaining a healthy weight
• C. Poor circulation or blockage in the lymphatic system
• D. Proper hydration

Correct answer: C

Rationale: Edema is a condition where there is an abnormal accumulation of fluid in the body tissues, leading to swelling. Poor circulation or blockage in the lymphatic system can contribute to edema by hindering the proper drainage of lymph fluid. When the lymphatic system is not functioning efficiently, it can result in fluid retention and swelling in the affected areas. Regular exercise and maintaining a healthy weight can actually help improve circulation and lymphatic flow, reducing the risk of edema. Proper hydration is important for overall health but specifically does not directly contribute to the development of edema as poor circulation or lymphatic blockages do.

2. The dome-shaped muscular structure that separates the chest cavity from the abdominal cavity is the:

• A. Diaphragm
• B. Sternum
• C. Pericardium
• D. Trachea

Correct answer: A

Rationale: The correct answer is A: Diaphragm. The diaphragm is a dome-shaped muscular structure that plays a crucial role in respiration by contracting and flattening during inhalation to increase the volume of the thoracic cavity, allowing the lungs to expand and fill with air. It separates the chest cavity (thoracic cavity) from the abdominal cavity. The sternum (B) is a flat bone in the center of the chest, the pericardium (C) is a double-layered sac that surrounds the heart, and the trachea (D) is the windpipe that connects the larynx to the bronchi. Therefore, the diaphragm is the correct answer in this case.

3. As a manager, she focuses her energy on both the quality of services rendered to the patients

• A. Country club management
• B. Organization man management
• C. Team management
• D. Authority-obedience management

Correct answer: B

Rationale: The correct answer is 'B: Organization man management.' This type of management focuses on maintaining the efficiency and structure of an organization. In this scenario, the manager's emphasis on the quality of services aligns with the principles of organization man management, which prioritizes the coordination of tasks and resources to achieve optimal results within the organization. This contrasts with 'Country club management,' which emphasizes employee satisfaction over task accomplishment; 'Team management,' which focuses on collaboration and teamwork; and 'Authority-obedience management,' which centers on strict hierarchical control. Therefore, the most appropriate choice is 'B: Organization man management.'

4. What is the difference between a phylum and a class?

• A. Phylums are broader and more general
• B. Classes are broader and more general
• C. They are synonyms, used for the same groups
• D. Phylums are for plants, classes are for animals

Correct answer: A

Rationale: Rationale: In biological classification, a phylum is a higher taxonomic rank than a class. Phylum is a broader category that includes multiple classes within it. Phylum represents a group of organisms sharing a common body plan or evolutionary history, while a class is a more specific category within a phylum that includes organisms with similar characteristics. Therefore, phylums are broader and more general compared to classes.

5. Percent Increase/Decrease: A medication dosage is increased by 20%. If the original dosage was 100mg, what is the new dosage?

• A. 80mg
• B. 100mg
• C. 120mg
• D. 140mg

Correct answer: C

Rationale: Multiply the original dosage (100mg) by 1 + the percentage increase (20% = 0.2) to get 120mg.

6. What mineral is essential for muscle function and can cause cramps if deficient?

• A. Sodium
• B. Calcium
• C. Potassium
• D. Magnesium

Correct answer: B

Rationale: The correct answer is B: Calcium. Calcium is essential for muscle function, including muscle contraction and relaxation. A deficiency in calcium can lead to muscle cramps and spasms. While sodium, potassium, and magnesium are also important for muscle function, calcium specifically plays a crucial role in muscle contractions. Therefore, calcium is the mineral that is essential for muscle function and can cause cramps if deficient.
