1. Select the meaning of the underlined word in the following sentence. The patient is lying prone next to the monitor.

• A. Face down
• B. Immovable
• C. Face up
• D. Asleep

Correct answer: A

Rationale: The word 'prone' in the sentence 'The patient is lying prone next to the monitor' indicates that the patient is positioned face down. 'Prone' refers to the body position in which the front surface of the body, such as the chest or abdomen, is facing downwards. Therefore, choice A, 'Face down,' is the correct meaning. Choices B, 'Immovable,' C, 'Face up,' and D, 'Asleep,' are incorrect as they do not accurately describe the meaning of 'prone' in the context of the sentence.

2. Which classification best describes B, Si, As, Te, At, Ge, and Sb that form a staircase pattern on the right side of the periodic table?

• A. Metals
• B. Semimetals
• C. Nonmetals
• D. Ultrametals

Correct answer: B

Rationale: B, Si, As, Te, At, Ge, and Sb are located in a staircase pattern on the periodic table's right side. Elements in this region are known as metalloids or semimetals because they exhibit properties of both metals and nonmetals. They possess characteristics of both metallic and non-metallic elements, making them valuable semiconductors with diverse applications in electronics. Choice A is incorrect because these elements are not considered true metals. Choice C is incorrect as these elements do not display typical nonmetal properties exclusively. Choice D, 'Ultrametals,' is not a recognized classification in chemistry and is therefore incorrect.

3. In a bar graph showing the number of patients admitted to the ER each day for a week, how do you determine the day with the highest number of admissions?

• A. Find the tallest bar in the graph.
• B. Compare the heights of all bars.
• C. Calculate the average number of admissions per day.
• D. Subtract the lowest number of admissions from the highest.

Correct answer: A

Rationale: The correct answer is A: 'Find the tallest bar in the graph.' In a bar graph, the height of each bar represents the quantity being measured. The tallest bar indicates the day with the highest number of admissions. Therefore, this is the most direct and accurate method to determine the day with the highest number of admissions. Choices B, C, and D are incorrect because comparing all bars, calculating the average, or subtracting the lowest from the highest does not directly identify the day with the highest number of admissions in a bar graph.

4. Cobalt-60 has a half-life of 5 years. If you start with 20 g of cobalt-60, how much is left after 10 years?

• A. 15 g
• B. 10 g
• C. 5 g
• D. 2.5 g

Correct answer: C

Rationale: Cobalt-60's half-life of 5 years means that after 5 years, half of the initial amount remains. Therefore, after 10 years, a quarter (half of a half) of the initial amount will remain. Starting with 20 g, after 10 years, 5 g of cobalt-60 will be left. Choice A (15 g) is incorrect because it assumes a linear decrease, not considering the exponential decay characteristic of radioactive substances. Choice B (10 g) is incorrect as it overlooks that after 10 years, more decay has occurred. Choice D (2.5 g) is incorrect as it represents only an eighth of the initial amount after 10 years, not a quarter.

5. Select the phrase in the following sentence that is not used correctly: He had never had to be on his own in the past.

• A. had never
• B. never had
• C. to be
• D. on his own

Correct answer: C

Rationale: The phrase 'to be' is not used correctly in the sentence. The correct phrase should be 'to be' in this context. The infinitive form of the verb 'be' is used after 'to.' In this sentence, the infinitive form 'to be' should follow 'had' to form the correct structure. Choices A, B, and D are all used appropriately in the sentence, focusing on the order and placement of the words in the context provided.
