HESI A2 Practice Vocabulary

Correct Answer: B

Rationale: Step-by-step rationale: 1. A parameter is a characteristic or constant factor that defines a system. 2. It is not a constant variable (A) as it is not subject to change within a given context. 3. It is not a measurable limit (C) but rather a defining aspect of a system. 4. It is not a calculated risk (D) as it is not related to potential outcomes, but rather a fixed element. In summary, choice B is correct as a parameter is a specific, unchanging factor that characterizes a system, while the other choices do not accurately define the term.

Correct Answer: B

Rationale: The correct answer is B: To press downward. "Depress" means to push or press something downward or lower in position. This is evident in the prefix "de-" which signifies down or away. Choices A, C, and D are incorrect because they do not accurately reflect the meaning of "depress." Choice A, to push forward, is incorrect as it suggests a movement in a different direction. Choice C, to remove, is incorrect as it does not involve pressing down. Choice D, to elevate, is incorrect as it is the opposite of pressing downward.

Correct Answer: A

Rationale: The correct answer is A because it demonstrates empathy by showing understanding and relating to the patient's feelings of being lost in a new town. This response acknowledges and validates the patient's emotions, indicating a compassionate and supportive approach. In contrast, choices B, C, and D lack empathy. B focuses on the symptoms rather than the patient's emotional state, C emphasizes compliance with treatment without considering the patient's feelings, and D shows judgment and disbelief towards the patient's pain, lacking empathy and understanding.

Correct Answer: B

Rationale: The correct answer is B: Charitable. Altruism refers to selfless concern for the well-being of others. Being charitable aligns with this definition as it involves giving to others without expecting anything in return. Choice A (Selfish) is the opposite of altruistic, focusing on self-interest. Choice C (Greedy) and D (Hateful) are also opposite in nature, as they involve a focus on personal gain or negative feelings towards others, which contradict the concept of altruism. Therefore, B is the most suitable term to describe someone who is altruistic.

Correct Answer: B

Rationale: The correct answer is B: To make a liquid less concentrated. Dilute means to reduce the concentration of a substance by adding more solvent. This process results in a less concentrated solution. Choice A is incorrect because it is the opposite of dilute. Choice C, solidify, refers to the process of turning a liquid into a solid, which is not related to dilution. Choice D, evaporate, means to convert a liquid into a gas, which is also not the same as diluting a liquid. In summary, the correct answer, B, is the only choice that accurately defines the term "dilute" by describing the process of making a liquid less concentrated.
