1. What happens to the gravitational potential energy of an object as it falls freely?

• A. It decreases
• B. It increases
• C. It remains constant
• D. It becomes zero

Correct answer: a

Rationale: Gravitational potential energy decreases as an object falls freely due to a decrease in its height.

2. Which vitamin plays a crucial role in calcium absorption in the small intestine?

• A. Vitamin A
• B. Vitamin C
• C. Vitamin D
• D. Vitamin E

Correct answer: C

Rationale: The correct answer is C: Vitamin D. Vitamin D plays a crucial role in calcium absorption in the small intestine because it helps regulate the levels of calcium and phosphorus in the body. When vitamin D is present, it stimulates the production of proteins that facilitate the absorption of calcium from the intestine into the bloodstream. Without adequate levels of vitamin D, the body struggles to absorb calcium efficiently, which can lead to weakened bones and other health issues. While vitamins A, C, and E are important for various functions in the body, they do not directly impact calcium absorption in the same way that vitamin D does.

3. What is the SI unit of measurement for momentum?

• A. Newton (N)
• B. Kilogram-meter per second (kg·m/s)
• C. Joule (J)
• D. Newton-second (N·s)

Correct answer: b

Rationale: Momentum is measured in kilogram-meter per second (kg·m/s).

4. Identify the incorrect usage of punctuation in the following sentence: "The children, eager to play, ran outside. It was a beautiful day."

• A. comma after "children"
• B. comma after "play"
• C. period after "outside"
• D. no errors

Correct answer: C

Rationale: The two sentences are independent clauses and should be separated by a semicolon or period, not a comma.

5. 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.

6. When is work done by a force on an object?

• A. Only when the object moves in the direction of the force
• B. Only when the object moves against the force
• C. Only when the object moves vertically
• D. Only when the force is applied for a specific duration

Correct answer: A

Rationale: Work is done by a force on an object when the object moves in the direction of the force. If the object moves perpendicular to the force, no work is done, as the force does not contribute to the displacement of the object. Similarly, if the object moves against the force, work is done because the force is causing the displacement. The vertical movement of the object does not determine whether work is done; it is the direction of the force relative to the object's displacement that matters. The duration of the force application does not affect whether work is done; as long as the force causes the object to move in its direction, work is being done.
