1. A car is traveling at a constant speed on a straight road. What is the net force acting on the car?

• A. A force equal to its weight pushing upwards
• B. A force equal to its weight pushing downwards
• C. A force equal to its engine power pushing forward
• D. No net force

Correct answer: D

Rationale: Since the car's speed is constant, there is no acceleration, and according to Newton's first law, a net force of zero is required.

2. Which of the following is evidence that the controlling process is effective?

• A. The things that were planned are done
• B. Physicians do not complain.
• C. Employees are contended
• D. There is an increase in customer satisfaction rate.

Correct answer: A

Rationale: The correct answer is A: 'The things that were planned are done.' This is evidence that the controlling process is effective because it indicates that the organization is able to execute its plans successfully. When planned tasks and activities are completed as intended, it shows that the controlling function is ensuring that operations are on track and that deviations are being corrected. The completion of planned tasks also demonstrates that resources are being effectively utilized and that performance is being monitored and controlled. The other options do not directly relate to the effectiveness of the controlling process. Physicians not complaining, employees being contented, and an increase in customer satisfaction rate could be influenced by various factors and may not necessarily be solely attributed to the effectiveness of the controlling process.

3. The fluid-filled sacs that cushion the brain within the skull are called:

• A. Meninges
• B. Cerebrospinal fluid
• C. Dura mater
• D. Arachnoid mater

Correct answer: B

Rationale: The correct answer is B: Cerebrospinal fluid. Cerebrospinal fluid is a clear, colorless fluid that surrounds the brain and spinal cord, acting as a cushion to protect the central nervous system from injury. Meninges (Option A) are the protective membranes that cover the brain and spinal cord, while the dura mater (Option C) and arachnoid mater (Option D) are specific layers of the meninges. However, cerebrospinal fluid is the fluid-filled sac that directly cushions the brain within the skull, making it the most appropriate answer for this question.

4. In the phrase "a drop in the bucket," "bucket" represents:

• A. A literal container
• B. A large quantity
• C. A specific goal
• D. An obstacle

Correct answer: B

Rationale: The phrase signifies that something is insignificant compared to a much larger amount.

5. Aseptic meningitis is an inflammation of the meninges caused by:

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

Correct answer: B

Rationale: Rationale: Aseptic meningitis is typically caused by viral infections, such as enteroviruses (e.g., coxsackievirus, echovirus), herpes simplex virus, varicella-zoster virus, and others. These viruses can infect the meninges, leading to inflammation and symptoms of meningitis without the presence of bacteria. While bacterial meningitis is a serious and life-threatening condition, aseptic meningitis caused by viruses is usually less severe and has a better prognosis. Fungi and parasites are less common causes of meningitis compared to bacteria and viruses.

6. The three main types of muscle tissue in the human body are:

• A. Smooth, cardiac, and voluntary skeletal
• B. Smooth, skeletal, and involuntary cardiac
• C. Voluntary smooth, cardiac, and skeletal
• D. Striated, non-striated, and epithelial

Correct answer: A

Rationale: The correct answer is A: Smooth, cardiac, and voluntary skeletal. Smooth muscle is found in the walls of internal organs and blood vessels, cardiac muscle makes up the heart, and voluntary skeletal muscle is attached to the bones and responsible for movement. Choice B is incorrect because cardiac muscle is involuntary, not voluntary. Choice C is incorrect because smooth muscle and cardiac muscle are involuntary, not voluntary. Choice D is incorrect because 'striated' and 'non-striated' refer to the appearance of muscle fibers, not the main types of muscle tissue in the body.
