1. 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.

2. The Minimum Inhibitory Concentration (MIC) of an antibiotic refers to:

A. The lowest concentration that kills bacteria
B. The dose required for 50% bacterial inhibition
C. The time it takes for an antibiotic to work
D. The spectrum of bacteria the antibiotic targets

Correct answer: B

Rationale: Rationale: A) The lowest concentration that kills bacteria is known as the Minimum Bactericidal Concentration (MBC), not the Minimum Inhibitory Concentration (MIC). MIC is the lowest concentration of an antibiotic that inhibits visible growth of bacteria. B) The MIC of an antibiotic is the concentration at which bacterial growth is inhibited by 50%. This concentration is used to determine the effectiveness of an antibiotic against a specific bacterium. C) The time it takes for an antibiotic to work is not described by the MIC. MIC is a measure of concentration, not time. D) The spectrum of bacteria the antibiotic targets is not defined by the MIC. The MIC value is specific to a particular antibiotic and bacterium, regardless of the spectrum of activity of the antibiotic.

3. Stretch marks occur when

A. The dermis layer becomes inflamed
B. The dermis layer becomes inflamed
C. The dermis layer tears due to rapid stretching
D. Sebaceous glands become clogged

Correct answer: C

Rationale: Stretch marks occur when the dermis layer tears due to rapid stretching. During periods of rapid growth or weight gain, the skin may stretch beyond its capacity, causing the dermis layer to tear and resulting in the formation of stretch marks. Inflammation or clogged sebaceous glands do not directly cause stretch marks, making options A, B, and D incorrect. It is important to understand the physiological process behind stretch marks to identify the correct answer.

4. Define "friction" in terms of opposing motion.

A. A force that increases motion
B. A force that accelerates motion
C. A force that opposes motion
D. A force that creates motion

Correct answer: c

Rationale: Friction acts opposite to the direction of motion, resisting or slowing down the movement of objects.

5. In the female reproductive system, what structure produces eggs (ova)?

A. Fallopian tubes
B. Ovaries
C. Uterus
D. Vagina

Correct answer: A

Rationale: The correct answer is B: Ovaries. The ovaries are the primary reproductive organs in the female body responsible for producing eggs (ova) through a process called ovulation. The fallopian tubes serve as the passageway for the egg to travel from the ovary to the uterus for potential fertilization. The uterus is where a fertilized egg implants and develops into a fetus during pregnancy. The vagina is the muscular canal that connects the uterus to the outside of the body and serves as the birth canal during childbirth. Therefore, the ovaries are specifically responsible for the production of eggs in the female reproductive system.
