HESI A2 Vocabulary Practice Test

Correct Answer: B

Rationale: The correct answer is B: Enlarged. 'Distended' means swollen or enlarged, which fits the context of the sentence describing the patient's veins. Veins can become distended when there is increased pressure or volume of blood within them. Bleeding (A) does not relate to the meaning of distended. Pressure (C) is related but doesn't capture the full meaning of swollen or enlarged. Minuscule (D) means very small, which is the opposite of distended. Therefore, choice B is the most appropriate meaning for 'distended' in this context.

Correct Answer: B

Rationale: The correct answer is B: Produced within the body. Endogenous refers to something that originates or is produced internally by the body. In this context, endogenous substances are naturally produced by the body's cells or organs. Choices A, C, and D are incorrect because endogenous specifically refers to internal production and is not related to being produced outside the body, taken from an external source, or linked to environmental factors. Therefore, the correct choice is B as it accurately reflects the definition of endogenous.

Correct Answer: B

Rationale: The correct answer is B: A deficiency or lack of something. 'Deficit' refers to a shortage or insufficiency of a particular quantity or quality. It is the opposite of an excess (choice A), abundance (choice C), or a stable amount (choice D). The term 'deficit' specifically implies a lack or inadequacy in comparison to what is required or expected.

Correct Answer: A

Rationale: The correct answer is A: Breathe. In this context, the child with a stuffy nose would find it hard to perform the action of breathing due to nasal congestion. "Breathe" is the correct verb form that indicates the act of inhaling and exhaling. The other choices are incorrect: B: Breathing is a noun form, C: Breath is a noun form, and D: Breadth refers to the extent or measure of something, none of which fit the context of the sentence. Thus, the correct answer is A as it accurately describes the difficulty the child would face due to a stuffy nose.

Correct Answer: B

Rationale: The correct answer is B: Confinement away from the general population. Quarantine refers to the isolation of individuals who may have been exposed to a contagious disease to prevent the spread to others. This choice is correct because quarantine involves separating potentially infected individuals from the rest of the population. Choice A (Isolation) is similar but not specific to disease control measures. Choice C (Treatment) does not capture the concept of separation. Choice D (Exposure) is incorrect as quarantine is about preventing exposure, not promoting it.
