HESI A2 vocabulary practice questions set 2

Correct answer:

The word 'sanguinary' is derived from the Latin word 'sanguinarius,' meaning bloodthirsty or bloodshed. In the context of the sentence, 'sanguinary' is used to indicate that surgery is a procedure that involves bloodshed. Therefore, the correct answer is B. Choice A ('Hopeful or cheerful') is incorrect because 'sanguinary' does not convey a positive or cheerful meaning. Choice C ('Difficult and protracted') is incorrect as 'sanguinary' specifically relates to blood or bloodshed, not difficulty or prolongation. Choice D ('Tricky and sensitive') is incorrect as 'sanguinary' does not imply trickiness or sensitivity but rather the presence of blood or bloodshed.

Correct answer:

The correct answer is A: "convulsion." A paroxysm is defined as a sudden spasm or convulsion. The word "convulsion" specifically refers to a violent and involuntary contraction or spasm of muscles, which aligns perfectly with the description of a paroxysm. On the other hand, choices B, C, and D are incorrect. "Symptom" (B) refers to a manifestation of a condition rather than a physical spasm. "Efficacy" (C) relates to effectiveness or success, not a sudden spasm. "Embolism" (D) refers to the obstruction of a blood vessel, which is unrelated to the concept of a sudden spasm. Therefore, convulsion is the most suitable synonym for a paroxysm in this context.

Correct answer:

The correct answer is A: Dejected. After becoming INVALID, one is likely to feel dejected, meaning sad and disheartened due to feeling invalidated or rejected. It is a common emotional response to a situation where one's worth or validity is questioned or denied. Option B, shamefully fearful, does not directly relate to the emotional state associated with being an invalid. Option C, injured, does not capture the emotional aspect but rather focuses on the physical condition. Option D, symbiotic, refers to a mutually beneficial relationship between two different organisms and is not relevant to the emotional state of an individual after becoming an invalid.

Correct answer:

The correct answer is A: 'Is.' In this sentence, 'Economics' is being treated as a singular subject, so the verb should also be singular. 'Is' is the correct singular form of the verb to agree with the singular subject 'Economics.' Choice B, 'Been,' is incorrect because it is the past participle form of the verb 'be' and does not agree with the singular subject 'Economics.' Choice C, 'Am,' is incorrect because it is the first-person singular form of the verb 'be' and does not agree with the singular subject 'Economics.' Choice D, 'Are,' is incorrect because it is the plural form of the verb 'be' and does not agree with the singular subject 'Economics.'

Correct answer:

Hypothetical is best defined as being assumed because it describes something that is based on a theory or assumption rather than solid proof or certainty. Hypothetical situations are used to explore different possibilities or outcomes without being confirmed as true or existing. Choice A, 'rigorous,' does not accurately define hypothetical, as it refers to something that is extremely thorough, accurate, or carefully done. Choice B, 'short-term,' is unrelated to the definition of hypothetical. Choice D, 'convinced,' does not capture the essence of hypothetical, which is more about assumptions and possibilities rather than being convinced of something.

Correct answer:

The word 'deleterious' means causing harm or damage. In this context, the sentence implies that the chemicals in plastic containers can be harmful to children's health. Therefore, the correct meaning of the underlined word is 'harmful,' making option A the most suitable choice. Option B 'Deleting' is incorrect because it refers to removing or erasing, which does not fit the context. Option C 'Delightful' is incorrect as it means causing great pleasure or delight, the opposite of the intended meaning. Option D 'Inoffensive' is incorrect as it means not causing any harm or annoyance, which is contrary to the negative impact described in the sentence.

Correct answer:

In this sentence, the correct option is 'had run' as it is the past perfect tense, which is used to indicate an action completed before another past action. The sentence structure requires the past perfect form to show that the running occurred before catching up with the man. 'Ran' (choice A) is in simple past tense and does not convey the sequence of events correctly. 'Chased' (choice C) is the simple past tense of the verb 'chase' and does not align with the past perfect tense needed in the sentence. 'Drove' (choice D) is incorrect as it refers to using a vehicle to pursue someone, whereas the context of the sentence indicates running on foot.

Correct answer:

The correct answer is D: 'Stoutness.' The word 'corpulence' refers to the state of being excessively fat or overweight, indicating the patient's stoutness or large size due to excess body weight. Choice A, 'Belligerence,' is incorrect as it means aggressive or hostile behavior, which does not fit the context of the sentence. Choice B, 'Gassiness,' is incorrect as it refers to the state of having excessive gas in the digestive system, which is unrelated to the patient's physical size. Choice C, 'Wariness,' is incorrect as it means cautiousness or being alert, which is not relevant to the patient's physical appearance described in the sentence.

Correct answer:

To aspirate fluid, you would typically use a syringe. A syringe is a device consisting of a tube and a plunger, which allows you to draw fluids such as blood or medication into the tube by pulling back on the plunger. This action is called aspiration, and the syringe is a common tool for this purpose in various medical procedures. Choices B, C, and D are incorrect as they are not typically used for aspiration procedures. A beaker is a glass container used for holding liquids, a test tube is used for holding or mixing small quantities of substances, and a flange is a projecting rim or edge used for strength or for attaching to another object.

Correct answer:

In the context of the sentence, the word 'placebo' refers to a substance or treatment that resembles a real medical treatment but has no therapeutic effect. It is used as a standard against which the effects of the experimental drug are compared. A placebo is typically included in a control group in medical research to evaluate the actual effects of the experimental drug. Therefore, in this scenario, the placebo serves as a control to gauge the effectiveness of the experimental drug, making choice C the correct answer. Choices A, B, and D are incorrect because a placebo is not a fallback, substitute, or curative treatment in this context.
