1. Saliva contains an enzyme that breaks down carbohydrates. What is the name of this enzyme?

• A. Pepsin
• B. Amylase
• C. Lipase
• D. Trypsin

Correct answer: B

Rationale: The correct answer is B: Amylase. Saliva contains the enzyme amylase, which is responsible for breaking down carbohydrates into simpler sugars like maltose and glucose. Pepsin (A) is an enzyme found in the stomach that breaks down proteins. Lipase (C) is an enzyme that breaks down fats, and trypsin (D) is another enzyme that breaks down proteins, but both of these are not found in saliva. Knowing the function of amylase in saliva helps in the digestion of carbohydrates, making it the correct answer.

2. Which orbital can hold a maximum of 8 electrons?

• A. s orbital
• B. p orbital
• C. d orbital
• D. f orbital

Correct answer: C

Rationale: d orbital - Each d orbital can hold a maximum of 2 electrons, and there are 5 d orbitals, totaling 10 possible electrons.

3. As a manager, she focuses her energy on both the quality of services rendered to the patients

• A. Country club management
• B. Organization man management
• C. Team management
• D. Authority-obedience management

Correct answer: B

Rationale: The correct answer is 'B: Organization man management.' This type of management focuses on maintaining the efficiency and structure of an organization. In this scenario, the manager's emphasis on the quality of services aligns with the principles of organization man management, which prioritizes the coordination of tasks and resources to achieve optimal results within the organization. This contrasts with 'Country club management,' which emphasizes employee satisfaction over task accomplishment; 'Team management,' which focuses on collaboration and teamwork; and 'Authority-obedience management,' which centers on strict hierarchical control. Therefore, the most appropriate choice is 'B: Organization man management.'

4. If 3 nurses can care for 15 patients, how many nurses are needed for 25 patients?

• A. 4
• B. 5
• C. 6
• D. 7

Correct answer: B

Rationale: 3 nurses / 15 patients = x nurses / 25 patients. Solve for x.

5. Which of the following is NOT a route of transmission for a sexually transmitted infection (STI)?

• A. Unprotected sexual contact
• B. Sharing contaminated needles
• C. Deep kissing
• D. Mother to child during childbirth

Correct answer: C

Rationale: Rationale: A) Unprotected sexual contact is a common route of transmission for sexually transmitted infections (STIs) as many STIs are spread through genital, anal, or oral sex without the use of barrier protection such as condoms. B) Sharing contaminated needles can also transmit STIs such as HIV and hepatitis B and C, especially among individuals who inject drugs. C) Deep kissing, while it can transmit certain infections like herpes simplex virus (HSV-1) or cytomegalovirus (CMV), is not a common route of transmission for most STIs. D) Mother to child transmission during childbirth can occur with certain STIs such as HIV, syphilis, and herpes, where the infection can be passed from the mother to the baby during delivery. Therefore, deep kissing (option C) is the correct answer as it is not a typical route of transmission for most STIs.

6. An ancient Egyptian pyramid has a square base with side lengths of 20 meters and a remaining height (after erosion) of 10 meters. Its original height was 30 meters. What was the volume of the pyramid in its original state?

• A. 12000 cu m
• B. 6000 cu m
• C. 18000 cu m
• D. 24000 cu m

Correct answer: A

Rationale: Use the formula for the volume of a pyramid with the original height and base area.
