1. What is the law of conservation of energy?

• A. Energy cannot be created, only destroyed
• B. Energy can be created but not destroyed
• C. Energy can neither be created nor destroyed, only transformed from one form to another
• D. Energy is always created in any process

Correct answer:

Rationale: According to the law of conservation of energy, the total energy in a closed system remains constant; it can change forms but cannot be created or destroyed.

2. Define the term "velocity" in relation to motion.

• A. Speed in a specific direction
• B. Distance traveled in a given time
• C. Rate of change of position
• D. Acceleration due to gravity

Correct answer:

Rationale: Velocity is the rate of change of position concerning direction, unlike speed which only refers to distance traveled per unit time.

3. Which statement accurately defines power?

• A. Power is the amount of energy stored in an object
• B. Power is the rate at which energy is transferred or work is done
• C. Power is the maximum force exerted by an object
• D. Power is the resistance of an object to change in motion

Correct answer: b

Rationale: Power measures how quickly work is done or energy is transferred or converted.

4. Temperature Conversion & Interpretation: A patient's body temperature is 102°F. Convert this to °C and assess if it indicates a fever.

• A. 37°C (Normal)
• B. 39°C (Low-grade fever)
• C. 39°C (Fever)
• D. 42°C (Hyperthermia)

Correct answer: C

Rationale: Rationale: 1. To convert Fahrenheit to Celsius, you can use the formula: °C = (°F - 32) x 5/9. 2. Given that the patient's body temperature is 102°F, we can calculate the equivalent temperature in Celsius: °C = (102 - 32) x 5/9 °C = 70 x 5/9 °C = 350/9 °C ≈ 38.9°C, which can be rounded to 39°C. 3. A body temperature of 39°C is considered to indicate a fever. Normal body temperature typically ranges from 36.1°C to 37.2°C, so a temperature of 39°C is higher than the normal range and suggests a fever. 4. Options A and B are incorrect as they do not reflect the conversion of 102°F to °C

5. When a blockage forms in a coronary artery, reducing blood flow to the heart muscle, this condition is called:

• A. Atherosclerosis
• B. Myocardial infarction
• C. Angina pectoris
• D. Heart murmur

Correct answer: C

Rationale: The correct answer is C: "Angina pectoris." Angina pectoris is the condition that occurs when there is a blockage in a coronary artery, leading to reduced blood flow to the heart muscle. This decreased blood flow can cause chest pain or discomfort, typically during physical exertion or stress. Atherosclerosis (option A) is the buildup of plaque in the artery walls, which can lead to blockages. Myocardial infarction (option B) refers to a heart attack, which occurs when there is a complete blockage in a coronary artery resulting in damage to the heart muscle. A heart murmur (option D) is an abnormal sound heard during the heartbeat, not directly related to a blockage in a coronary artery. Therefore, the correct term for a blockage in a coronary artery that reduces blood flow to the heart muscle is angina pectoris.

6. She surfs the internet for more information about leadership styles. She reads about shared

• A. Leadership behavior is generally determined by the relationship between the leader’s
• B. Leaders believe that people are basically good and need not be closely controlled
• C. Leaders rely heavily on visioning and inspire members to achieve results
• D. Leadership is shared at the point of care.

Correct answer: B

Rationale: The correct answer is B because the statement 'Leaders believe that people are basically good and need not be closely controlled' aligns with the concept of shared leadership. Shared leadership involves distributing leadership responsibilities and authority among team members based on the belief that everyone has valuable contributions to make. This approach fosters a sense of trust and empowerment within the team, allowing individuals to take initiative and collaborate effectively. In contrast, option A refers to leadership behavior being determined by the relationship between the leader and followers, which is not directly related to the concept of shared leadership. Option C emphasizes visioning and inspiration, which are important aspects of leadership but do not specifically address the shared nature of leadership. Option D mentions leadership being shared at the point of care, which is too specific and does not encompass the broader concept of shared leadership.
