1. If a patient’s condition is deteriorating, he is ___________.

• A. getting worse
• B. improving gradually
• C. resisting medication
• D. failing to eat or drink

Correct answer: A

Rationale: When a patient's condition is deteriorating, it means that their health is declining or worsening. This can involve a range of factors such as worsening symptoms, declining vital signs, or an overall decline in health status. In this context, the phrase 'getting worse' best describes the situation of a patient whose condition is deteriorating. Choices B, C, and D are incorrect because they do not reflect the concept of deterioration in a patient's health. Improving gradually (choice B) indicates a positive trend, resisting medication (choice C) suggests a behavioral response, and failing to eat or drink (choice D) points to a specific issue rather than a general decline in health.

2. A farmer buys 3 bags of feed weighing 50 kilograms each. How much feed does he have in total?

• A. 100 kilograms
• B. 150 kilograms
• C. 200 kilograms
• D. 250 kilograms

Correct answer: B

Rationale: The correct answer is B: 150 kilograms. To find the total amount of feed, you need to multiply the number of bags by the weight of each bag. In this case, 3 bags * 50 kilograms each = 150 kilograms. Therefore, the farmer has a total of 150 kilograms of feed. Choice A (100 kilograms) is incorrect because it doesn't consider the total weight of all 3 bags. Choice C (200 kilograms) and Choice D (250 kilograms) are incorrect as they are miscalculations of the total weight of the feed.

3. What is the main function of white blood cells?

• A. To carry oxygen
• B. To fight infections
• C. To carry nutrients
• D. To remove waste products

Correct answer: B

Rationale: The main function of white blood cells, also known as leukocytes, is to fight infections and foreign invaders to protect the body from harm. They play a crucial role in the immune system by identifying and destroying pathogens like bacteria and viruses, essential for maintaining the body's health and overall immunity. Choices A, C, and D are incorrect as carrying oxygen is primarily done by red blood cells, carrying nutrients is a function of various body systems, and removing waste products is mainly the role of the kidneys and liver, not white blood cells.

4. Choose the meaning of the word 'intramuscularly' in the following sentence: 'This vaccine must only be used intramuscularly and as a single-dose vial.'

• A. Between muscles
• B. Into muscles
• C. Without muscles
• D. On top of muscles

Correct answer: B

Rationale: The word 'intramuscularly' in the sentence indicates that the vaccine should be used by injection directly into the muscles. This means the correct meaning is 'into muscles,' making option B the most suitable choice. Choices A, C, and D are incorrect because 'intramuscularly' specifically refers to administering something inside the muscle, not between muscles, without muscles, or on top of muscles.

5. According to the Law of Universal Gravitation, the gravitational force between two objects is directly proportional to what factor?

• A. the gravitational constant
• B. the distance between them
• C. the product of their masses
• D. the square of the distance between them

Correct answer: C

Rationale: According to the Law of Universal Gravitation, the gravitational force between two objects is directly proportional to the product of their masses. The equation is: F = G × (m₁ × m₂) / r², where F is the gravitational force, G is the gravitational constant, m₁ and m₂ are the masses of the two objects, and r is the distance between them. Choice A is incorrect because the gravitational constant is a constant value. Choice B is incorrect because the distance between the objects affects the strength of the gravitational force inversely proportional to the square of the distance, not directly proportional. Choice D is incorrect as it represents the inverse square law, where the gravitational force decreases with the square of the distance between the objects.
