1. 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.

2. The most common cause of hospital-acquired infections (HAIs) are:

• A. Viruses
• B. Bacteria
• C. Fungi
• D. Parasites

Correct answer: B

Rationale: Rationale: Hospital-acquired infections (HAIs), also known as nosocomial infections, are infections that patients acquire during the course of receiving treatment in a healthcare facility. Among the options provided, bacteria are the most common cause of HAIs. Bacteria such as Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa are known to cause a wide range of infections in healthcare settings. While viruses, fungi, and parasites can also cause HAIs, bacteria are the most prevalent and significant pathogens responsible for these infections. Proper infection control measures, including hand hygiene, environmental cleaning, and antimicrobial stewardship, are essential in preventing and controlling HAIs caused by bacteria.

3. 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.

4. Two scientists analyze the same data set on climate change, but they reach different conclusions. What is the MOST likely reason for this difference?

• A. One scientist has more experience than the other.
• B. They used different statistical methods.
• C. They have different personal biases.
• D. One scientist has access to additional data.

Correct answer: B

Rationale: Different analysis methods can lead to different interpretations, even with the same data. Biases and experience might play a role but are less likely the primary cause.

5. Differentiate between epithelial and connective tissue.

• A. Epithelial tissue is exclusively found in the lungs, while connective tissue supports tendons.
• B. Both are composed of cells, but epithelial tissue lines surfaces and glands, while connective tissue binds other tissues.
• C. Epithelial tissue is more vascularized, while connective tissue is responsible for muscle contraction.
• D. Epithelial tissue is the largest tissue type, while connective tissue is the smallest.

Correct answer: B

Rationale: Epithelial tissue covers surfaces and lines organs, while connective tissue provides support and structure throughout the body. Both are composed of cells, but their functions and locations differ.

6. He asserts the importance of promoting a positive organizational culture in their unit. Which

• A. Proactive and caring with one another
• B. Competitive and perfectionist
• C. Powerful and oppositional
• D. Obedient and uncomplaining

Correct answer: A

Rationale: The correct answer is A: 'Proactive and caring with one another.' When promoting a positive organizational culture, it is essential to foster a supportive environment where individuals are proactive in their approach and demonstrate care towards one another. This type of culture encourages collaboration, open communication, and empathy among team members, leading to higher levels of job satisfaction and overall performance. Being competitive and perfectionist (option B) can create a stressful and unhealthy work environment, while being powerful and oppositional (option C) or obedient and uncomplaining (option D) can stifle creativity and innovation. Therefore, the most suitable traits for promoting a positive organizational culture are being proactive and caring with one another.
