1. Express 2/5 as a decimal.

Correct answer: C

Rationale: To express 2/5 as a decimal, you divide the numerator (2) by the denominator (5). 2 ÷ 5 = 0.4. Choice A (0.2) is the decimal equivalent of 1/5, not 2/5. Choice B (0.25) is the decimal equivalent of 1/4, not 2/5. Choice D (2.5) is not the correct decimal equivalent of 2/5 as it is greater than 1.

2. What is the name for the horizontal rows of the periodic table?

Correct answer: B

Rationale: In the periodic table, 'periods' are the horizontal rows. Each period corresponds to the energy level occupied by the elements in that row. The other terms mentioned, such as groups, families, and sets, are not used to describe the horizontal rows but rather refer to different aspects of the periodic table organization. 'Groups' are the vertical columns, 'families' are groups of elements with similar properties, and 'sets' is a more generic term not specifically used in the context of the periodic table.

3. How does the circulatory system work with the digestive system?

Correct answer: C

Rationale: The circulatory system works with the digestive system by transporting absorbed nutrients through the body. After digestion occurs in the digestive system, nutrients are absorbed into the bloodstream. The circulatory system then carries these nutrients to cells throughout the body where they are used for energy, growth, and repair. This process ensures that the necessary nutrients are delivered to where they are needed in the body. Choices A, B, and D are incorrect because the circulatory system is not responsible for removing undigested solids, filtering and collecting digested materials, or releasing enzymes that control digestion. These functions are primarily carried out by the digestive system.

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

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.

5. Which type of radiation involves the emission of helium ions?

Correct answer: B

Rationale: Alpha radiation involves the emission of helium ions. Helium ions are composed of two protons and two neutrons, which is the same as the nucleus of a helium atom. This type of radiation has low penetration power and can be stopped by a piece of paper or human skin, making it less harmful compared to other forms of radiation like beta or gamma radiation. Beta radiation involves the emission of high-speed electrons, while gamma radiation involves electromagnetic waves with high energy. Delta radiation is not a recognized form of radiation in this context, making it an incorrect choice.
