1. A table shows the blood pressure readings for different age groups. How do you determine the patient with the highest systolic pressure?

• A. Find the largest number in the "systolic pressure" column.
• B. Compare the means (averages) of each age group.
• C. Add all systolic pressure values and divide by the total number of patients.
• D. Subtract the lowest systolic pressure from the highest.

Correct answer: A

Rationale: The best way is to compare the average systolic pressure values for each age group to identify the highest.

2. Emerging infectious diseases (EIDs) pose a significant public health threat because they are:

• A. Well-understood by medical professionals
• B. Easily treatable with existing antibiotics
• C. New, rapidly evolving, and can spread quickly
• D. Primarily affect animals and not humans

Correct answer: C

Rationale: Rationale: Emerging infectious diseases (EIDs) are a significant public health threat because they are characterized by being new or newly identified diseases that are rapidly evolving. These diseases can spread quickly within populations due to factors such as globalization, travel, urbanization, and changes in climate. EIDs often present challenges to medical professionals as they may not be well-understood initially, making it difficult to develop effective treatments or preventive measures. While some EIDs can be treatable with existing antibiotics, the rapid evolution of these diseases can lead to the development of drug resistance, further complicating treatment efforts. Additionally, EIDs are not limited to affecting animals; they can also have serious implications for human health and well-being.

3. A blog post criticizes a scientific study due to the author's political views. Is this a valid critique?

• A. Yes, if the author identifies specific flaws in the methodology.
• B. Yes, if the author disagrees with the study's conclusions.
• C. o, scientific evaluation should be based on evidence, not personal beliefs.
• D. No, unless the author has scientific expertise themselves.

Correct answer: C

Rationale: Criticism in science should focus on methodology, data analysis, and evidence, not personal agendas or political opinions.

4. The intricate network of blood vessels responsible for transporting blood throughout the body is the:

• A. Lymphatic system
• B. Circulatory system
• C. Nervous system
• D. Respiratory system

Correct answer: B

Rationale: The correct answer is B: Circulatory system. The circulatory system is responsible for transporting blood, oxygen, nutrients, and other substances throughout the body. It consists of the heart, blood vessels (arteries, veins, and capillaries), and blood. The lymphatic system (A) is a separate system that helps to maintain fluid balance in the body and plays a role in the immune response. The nervous system (C) is responsible for transmitting signals between different parts of the body and the brain. The respiratory system (D) is responsible for the exchange of oxygen and carbon dioxide in the body through breathing. In this question, the circulatory system is specifically mentioned as the network of blood vessels responsible for transporting blood, making it the correct answer.

5. Which of the following is NOT a function of the integumentary system?

• A. Regulation of body temperature
• B. Protection from pathogens
• C. Synthesis of vitamin D
• D. Production of digestive enzymes

Correct answer: D

Rationale: The correct answer is D: "Production of digestive enzymes." The integumentary system primarily consists of the skin, hair, nails, and glands. Its main functions include regulating body temperature through processes like sweating and shivering, protecting the body from pathogens and external threats, and synthesizing vitamin D when exposed to sunlight. However, the production of digestive enzymes is not a function of the integumentary system. Digestive enzymes are primarily produced by organs such as the pancreas and salivary glands to aid in the breakdown of food in the digestive system, which is separate from the functions of the integumentary system.

6. What is the electron configuration of an atom?

• A. The arrangement of electrons in an atom's orbitals.
• B. The number of protons in an atom's nucleus.
• C. The number of neutrons in an atom's nucleus.
• D. The number of electrons in an atom's valence shell.

Correct answer: A

Rationale: The electron configuration of an atom refers to the arrangement of electrons in the atom's orbitals. This arrangement determines the atom's chemical properties and behavior. The number of protons in an atom's nucleus (option B) is known as the atomic number, while the number of neutrons in an atom's nucleus (option C) contributes to the atom's mass number. The number of electrons in an atom's valence shell (option D) is important for understanding the atom's reactivity and bonding behavior.
