HESI A2 Vocabulary Practice Test

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.

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: B

Rationale: The correct answer is B: To swallow for digestion. Ingestion refers to the process of taking food or liquid into the body to be digested. Swallowing is a key component of the ingestion process, which allows the food to move from the mouth to the stomach for digestion. Choice A (To chew) is incorrect as chewing is a preliminary step before ingestion. Choice C (To spit out) is incorrect as it is the opposite of ingestion. Choice D (To vomit) is incorrect as vomiting is the expulsion of contents from the stomach, not the intake process.

Correct Answer: B

Rationale: The correct answer is B because Manifestation refers to an indication or sign of a condition. It is not a treatment plan (C) or a type of diagnosis (D). While A is similar to B, a manifestation is more than just a symptom; it includes any observable sign that can indicate the presence of a condition. Therefore, B is the best choice as it encompasses the broad definition of Manifestation.

Correct Answer: A

Rationale: The correct answer is A: hung up. In this context, "hung up" means to end a phone call abruptly. The phrase "hung up on him" indicates that she ended the call without listening or responding to him. Choices B, C, and D do not fit the context. "Picked" and "held" do not convey the action of ending a call, while "held on" means to stay connected on the call, which contradicts the situation where she was mad at him. Therefore, A is the most appropriate choice.
