1. In medicine, to be resistant is to be ___________.

• A. unwilling
• B. unaffected by
• C. opposed to
• D. accepting of

Correct answer: B

Rationale: In medicine, when a microorganism or pathogen is described as resistant, it means that it is not affected by the drug or treatment being used against it. Resistance can develop due to various factors, making the pathogen no longer susceptible to the effects of the treatment. Therefore, the correct answer is 'unaffected by.' The other choices are incorrect: 'unwilling' and 'opposed to' do not accurately describe the concept of resistance in medicine, and 'accepting of' is the opposite of what resistance represents in this context.

2. When a car is driven for a long time, the pressure of air in the tires increases. This is best explained by which of the following gas laws?

• A. Boyle's law
• B. Charles' law
• C. Gay-Lussac's law
• D. Dalton's law

Correct answer: C

Rationale: Gay-Lussac's law, also known as the law of pressure-temperature, states that the pressure of a gas is directly proportional to its absolute temperature when the volume is constant. As a car is driven for a long time, the tires heat up due to friction and increased air pressure inside the tires. This results in an increase in temperature, causing the pressure of the air inside the tires to increase according to Gay-Lussac's law. Choices A, B, and D are incorrect. Boyle's law relates pressure and volume, Charles' law relates volume and temperature, and Dalton's law deals with the partial pressures of gases in a mixture.

3. What is the meaning of qualms?

• A. Misgivings
• B. Habits
• C. Serenity
• D. Dispatches

Correct answer: A

Rationale: Qualms refer to feelings of doubt, hesitation, or uneasiness about something. They are typically used to describe a person's reservations or concerns about a decision or action. This aligns with the meaning of 'misgivings,' making it the correct choice in this context. Choices B, C, and D are incorrect. 'Habits' refer to regular tendencies or practices, 'Serenity' refers to a state of calm or peace, and 'Dispatches' refer to sending off to a destination or taking care of a task promptly, none of which capture the meaning of 'qualms.'

4. Which brain structure is responsible for regulating hunger and thirst?

• A. Hypothalamus
• B. Cerebellum
• C. Medulla oblongata
• D. Cerebrum

Correct answer: A

Rationale: The correct answer is the hypothalamus. This brain structure plays a crucial role in regulating hunger, thirst, body temperature, and various autonomic functions. The hypothalamus is responsible for maintaining homeostasis by responding to sensory signals and releasing appropriate hormones to control these essential physiological processes. The cerebellum (Choice B) is primarily involved in coordinating movement and balance, not hunger and thirst. The medulla oblongata (Choice C) is responsible for regulating vital autonomic functions such as breathing and heartbeat, but not hunger and thirst. The cerebrum (Choice D) is involved in higher brain functions such as thinking, decision-making, and processing sensory information, but it is not primarily responsible for regulating hunger and thirst.

5. An individual who takes the magicoreligious perspective of illness and disease is likely to believe that his or her illness was caused by:

• A. germs and viruses.
• B. supernatural forces.
• C. eating imbalanced foods.
• D. an imbalance within his or her spiritual nature.

Correct answer: B

Rationale: The magicoreligious perspective of illness and disease is based on the belief that supernatural forces play a significant role in causing health problems. Individuals holding this perspective may believe that their illness was caused by curses, evil spirits, or other supernatural factors rather than conventional explanations like germs or viruses. This worldview influences how they perceive and seek treatment for their health conditions. Therefore, the correct answer is B) supernatural forces. Choices A, C, and D are incorrect because they do not align with the supernatural beliefs associated with the magicoreligious perspective. This perspective focuses on attributing illness to supernatural causes rather than biological, dietary, or spiritual imbalances.
