1. She reads about Path Goal theory. Which of the following behaviors is manifested by the

• A. Recognizes staff for going beyond expectations by giving them citations
• B. Challenges the staff to take individual accountability for their own practice
• C. Admonishes staff for being laggards.
• D. Reminds staff about the sanctions for non performance.

Correct answer: B

Rationale: The correct answer is B: 'Challenges the staff to take individual accountability for their own practice.' Path-Goal theory emphasizes the leader's role in motivating and guiding their team to achieve goals. This behavior aligns with the theory as it focuses on empowering employees to take ownership of their actions and responsibilities. By challenging staff to be individually accountable, the leader is providing clear direction and support, which can enhance motivation and performance within the team. Recognizing and rewarding staff for going beyond expectations (option A) would be more aligned with a transformational leadership style. Admonishing staff for being laggards (option C) and reminding staff about sanctions (option D) are not effective leadership behaviors according to the Path-Goal theory, as they do not focus on motivating and supporting employees to reach their goals.

2. What effect does doubling the net force applied to an object have on its acceleration, assuming mass remains constant?

• A. Acceleration doubles
• B. Acceleration is halved
• C. Acceleration remains the same
• D. Acceleration quadruples

Correct answer: a

Rationale: According to Newton's second law (F = ma), if mass remains constant and force doubles, acceleration also doubles.

3. Scoliosis is a condition characterized by abnormal lateral curvature of the spine. Which part of the spine is most commonly affected?

• A. Cervical spine (neck)
• B. Thoracic spine (upper back)
• C. Lumbar spine (lower back)
• D. All of the above

Correct answer: B

Rationale: The correct answer is B: Thoracic spine (upper back). Scoliosis typically affects the thoracic spine more commonly than the cervical or lumbar spine. The thoracic spine, which is the upper back region, is the most common area for the abnormal lateral curvature of the spine to occur in cases of scoliosis. This is due to the natural curvature and structure of the spine in this region. While scoliosis can affect other parts of the spine as well, the thoracic spine is most frequently impacted, making it the correct answer in this case.

4. Melatonin is a hormone produced by the pineal gland. What is its primary function?

• A. Regulate blood pressure
• B. Stimulate the digestive system
• C. Control sleep-wake cycles
• D. Maintain bone density

Correct answer: C

Rationale: The correct answer is C: 'Control sleep-wake cycles.' Melatonin is a hormone that plays a key role in regulating the body's sleep-wake cycle, also known as the circadian rhythm. The pineal gland releases melatonin in response to darkness, helping to signal to the body that it is time to sleep. By influencing the timing and quality of sleep, melatonin helps maintain a healthy sleep pattern and overall well-being. While blood pressure, digestive system stimulation, and bone density are important functions in the body, melatonin's primary function is to regulate the sleep-wake cycle.

5. Which sentence uses the past perfect tense correctly?

• A. By the time I arrived, the party had already begun.
• B. I wish I had studied harder for the exam.
• C. We will have finished the project by Monday.
• D. She had been waiting for hours before he finally showed up.

Correct answer: A

Rationale: Option A expresses an action ("party began") completed before another past action ("I arrived").

6. What is the main difference between white and brown adipose tissue?

• A. Location only
• B. Function and energy metabolism
• C. Color only
• D. Both white and brown have the same function

Correct answer: B

Rationale: The main difference between white and brown adipose tissue lies in their function and energy metabolism. White adipose tissue is primarily involved in energy storage, while brown adipose tissue is responsible for energy expenditure through thermogenesis. Brown adipose tissue contains a higher density of mitochondria and a unique protein called uncoupling protein 1 (UCP1) that allows for the generation of heat. This key distinction in function and energy metabolism sets white and brown adipose tissue apart, making option B the correct answer.
