HESI A2 Vocabulary Practice Test

1. What does the word Quarantine mean?

A. Isolation
B. Confinement away from the general population
C. Treatment
D. Exposure

Correct answer: B

Rationale: The correct answer is B: 'Confinement away from the general population.' Quarantine is the practice of isolating individuals who may have been exposed to a contagious disease but are not yet ill. This isolation helps prevent the potential spread of the disease. Choice A, 'Isolation,' is partially correct but does not capture the specific aspect of separation from the general population. Choice C, 'Treatment,' is incorrect as quarantine does not involve providing medical care but rather focusing on preventing transmission. Choice D, 'Exposure,' is also incorrect as quarantine is about separating potentially exposed individuals, not intentionally exposing them.

2. How does being overweight predispose a person to a particular condition?

A. Cancer
B. Diabetes
C. Heart disease
D. Obesity

Correct answer: B

Rationale: Being overweight increases the risk of developing conditions like diabetes. Excessive weight can lead to insulin resistance and metabolic dysfunction, which are key factors in the development of type 2 diabetes. While obesity is a result of being overweight, it is not a condition that being overweight predisposes a person to. Cancer and heart disease can also be influenced by weight but are not the primary conditions typically associated with being overweight.

3. What is the meaning of Regulations?

A. Rules for Conduct
B. Official Standards
C. Personal Guidelines
D. Suggestions

Correct answer: A

Rationale: Regulations refer to rules or directives established by authorities to govern conduct or actions. Therefore, the correct answer is A - 'Rules for Conduct.' Choice B, 'Official Standards,' is incorrect as regulations go beyond just setting standards to include specific rules for behavior. Choice C, 'Personal Guidelines,' is incorrect as regulations are not individualized but are generally applicable rules. Choice D, 'Suggestions,' is incorrect as regulations are mandatory and carry legal weight, unlike suggestions which are optional and not binding.

4. When you add sugar to it, your cup of coffee becomes not only sweet but also _____.

A. fattening
B. healthy
C. rich
D. flavorful

Correct answer: A

Rationale: When sugar is added to coffee, it not only becomes sweet but also 'fattening' due to the extra calories added. The term 'fattening' specifically refers to the potential weight gain associated with consuming sugary drinks. Choices B, C, and D do not accurately describe the impact of adding sugar to coffee. 'Healthy' is incorrect because adding sugar typically does not make a beverage healthier. 'Rich' and 'flavorful' may suggest taste qualities but do not address the caloric impact of sugar.

5. What is Diffusion?

A. Movement of materials from low concentration to high concentration
B. Movement of materials from high concentration to low concentration
C. Absorption of nutrients
D. Breaking of materials

Correct answer: B

Rationale: Diffusion is the process where substances move from an area of high concentration to an area of low concentration. This movement occurs due to the random motion of particles and continues until equilibrium is reached. Choice A is incorrect because diffusion occurs down the concentration gradient, from high to low concentration, not from low to high concentration. Choice C is incorrect as it refers to the uptake of substances by cells, not the general process of diffusion. Choice D is incorrect as it does not accurately describe the process of diffusion; diffusion involves the movement of substances, not the breaking of materials.
