1. What is the SI unit of measurement for acceleration?

• A. Meters per second (m/s)
• B. Newton (N)
• C. Meters (m)
• D. Meters per second squared (m/s²)

Correct answer: d

Rationale: Acceleration is measured in meters per second squared (m/s²) in the SI unit system.

2. Which type of muscle tissue contracts involuntarily and is found in organs like the heart and intestines?

• A. Skeletal muscle
• B. Cardiac muscle
• C. Smooth muscle
• D. All of the above

Correct answer: C

Rationale: The correct answer is C: Smooth muscle. Smooth muscle tissue contracts involuntarily and is found in organs like the heart and intestines. Skeletal muscle is responsible for voluntary movements, and cardiac muscle is specific to the heart. Therefore, smooth muscle is the only type of muscle tissue that fits the description provided in the question, making it the correct choice. Option D, 'All of the above,' is incorrect as it includes skeletal and cardiac muscles, which do not fit the criteria of being found in organs like the heart and intestines. Understanding the differences between these types of muscle tissue is crucial for comprehending their specific functions in the body.

3. Katherine is a young Unit Manager of the Pediatric Ward. Most of her staff nurses are senior

• A. Identify the source of the conflict and understand the points of friction
• B. Disregard what she feels and continue to work independently
• C. Seek help from the Director of Nursing
• D. Quit her job and look for another employment.

Correct answer: C

Rationale: The correct answer is C: Seek help from the Director of Nursing. As a young Unit Manager managing a team of senior staff nurses, Katherine may face challenges in leading and gaining the respect of her team due to the age and experience gap. Seeking help from the Director of Nursing can provide her with guidance, mentorship, and support in navigating these challenges. It is important for Katherine to communicate openly about any conflicts or issues she may be facing in order to address them effectively and maintain a positive work environment. Quitting her job (option D) should be considered as a last resort after exhausting all other possible solutions.

4. Which statement BEST summarizes the author's perspective on bioremediation for plastic pollution?

• A. It is the only viable solution to the problem and should be prioritized.
• B. It is a promising approach but requires further research and development.
• C. It is less effective than traditional methods and poses environmental risks.
• D. It is irrelevant to the problem and will not make a significant impact.

Correct answer: B

Rationale: The passage acknowledges the potential of bioremediation while highlighting the need for further research, indicating a balanced perspective.

5. The passage implies that achieving energy sustainability requires...

• A. solely relying on renewable energy sources for electricity generation.
• B. a combination of advancements in renewable energy production and management technologies.
• C. prioritizing economic benefits over environmental concerns when making energy choices.
• D. focusing solely on reducing energy consumption without addressing production sources.

Correct answer: B

Rationale: The passage emphasizes the need for both increasing renewable energy and managing its fluctuations, suggesting B as the key to sustainability.

6. During exercise, heart rate increases to deliver more oxygen to the body's tissues. What other cardiovascular response also increases?

• A. Blood pressure decreases
• B. Blood vessel diameter narrows
• C. Blood flow to muscles increases
• D. Blood viscosity thickens

Correct answer: A

Rationale: The correct answer is A: 'Blood pressure decreases.' When the heart rate increases during exercise to deliver more oxygen to the body's tissues, the blood pressure also tends to decrease. This is due to the enhanced efficiency of the heart in pumping blood, resulting in a lower pressure exerted on the blood vessel walls. In contrast, options B and D are incorrect as blood vessel diameter typically widens (dilates) during exercise to facilitate increased blood flow, and blood viscosity does not usually thicken during exercise. Option C is a distractor as blood flow to muscles indeed increases during exercise to meet the higher demand for oxygen and nutrients.
