HESI A2 Vocabulary Practice Test

Correct Answer: A

Rationale: First, Regulations are specific and mandatory guidelines set by an authority, similar to rules. Therefore, choice A, "Rules for Conduct," aligns with this definition. Choice B, "Official Standards," may refer to general guidelines, not necessarily mandatory like regulations. Choice C, "Personal Guidelines," implies individual choices, not imposed by an authority. Choice D, "Suggestions," are not mandatory like regulations.

Correct Answer: B

Rationale: The correct answer is B: Significantly important and dangerous. "Ominous" means giving the impression that something bad or unpleasant is going to happen. The word carries a sense of foreboding or threat. Choice A, "insignificant," is incorrect because ominous implies significance. Choice C, "trivial," is incorrect as it suggests unimportance, which is opposite to the meaning of ominous. Choice D, "harmless," is incorrect because ominous implies a potential for harm or danger. Therefore, the correct answer is B as it best captures the meaning of ominous in the context of something being important and dangerous.

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: C

Rationale: Rationale: 1. Contemplating means deep thinking or reflecting. 2. Pondering also means to reflect or consider deeply. 3. Impasse means a deadlock or stalemate, not related to contemplating. 4. Impartial means unbiased, not directly related to contemplating. 5. Emending means to make corrections, not synonymous with contemplating. Summary: - A (Impasse) and D (Emending) are incorrect as they do not relate to contemplating. - B (Impartial) is incorrect as it does not represent the act of deep thinking. - C (Pondering) is correct as it directly aligns with the meaning of contemplating, involving thoughtful consideration.

Correct Answer: A

Rationale: The correct answer is A because absorption refers to the process of nutrients moving from the digestive tube into the bloodstream for utilization by the body. This process occurs primarily in the small intestine through the villi and microvilli. Choice B is incorrect as it describes the secretion of enzymes into the stomach, which is related to digestion, not absorption. Choice C is also incorrect as it describes the absorption of water from the intestines, which is a separate process from the absorption of nutrients. Choice D is incorrect because it refers to the excretion of waste from the body, which is the opposite of absorption. Therefore, the movement of nutrients from the digestive tube into the bloodstream best defines absorption in the context of human physiology.
