HESI A2 Vocabulary 2024

Correct Answer: C

Rationale: The correct answer is C: formulaic. Systematic refers to being organized and planned, which aligns with the definition of formulaic, suggesting a structured and methodical approach. In contrast, A (involuntary) means not done by choice, B (universal) refers to being applicable everywhere, and D (manual) pertains to being done by hand. Therefore, C is the most suitable synonym for systematic in this context.

Correct Answer: C

Rationale: The correct answer is C: tired. Enervated means lacking in energy or vitality. An enervated patient would exhibit symptoms of fatigue, weakness, and lack of physical or mental strength. Choice A (anxious) refers to a state of worry or unease, not necessarily related to energy levels. Choice B (immature) pertains to lacking maturity, which is unrelated to the patient's energy levels. Choice D (frightened) indicates fear or anxiety, which is also not directly related to the patient's energy levels. Thus, the most appropriate description for an enervated patient is tired due to the associated lack of energy and vitality.

Correct Answer: A

Rationale: The correct answer is A: Unfavorable. In the sentence, 'adverse' is used to describe a reaction caused by the medicine, indicating that it is not beneficial and has negative effects. 'Unfavorable' aligns with this meaning as it conveys something that is not conducive or adverse. The other choices are incorrect because B: Contrary means opposite, C: Noticeable means easily observed, and D: Startling means surprising, none of which capture the negative connotation of 'adverse' in this context.

Correct Answer: B

Rationale: The correct answer is B: Into muscles. 'Intramuscularly' refers to the administration of a substance directly into the muscle tissue. In the context of the sentence, it indicates how the vaccine should be used. Choice A (Between muscles) is incorrect as it does not accurately reflect the meaning of 'intramuscularly.' Choice C (Without muscles) is incorrect as it is the opposite of the intended meaning. Choice D (On top of muscles) is also incorrect as it does not involve penetration into the muscle tissue. Therefore, the correct choice is B because it best aligns with the definition of 'intramuscularly.'

Correct Answer: C

Rationale: The correct answer is C: Remedy. An antidote is a substance that counteracts the effects of a poison or toxin. A remedy is a solution or treatment for a problem or illness, which aligns with the purpose of an antidote. Purity (A) refers to being free from contamination, habitat (B) is the natural environment of an organism, and venom (D) is a poisonous substance injected by animals like snakes or insects. These choices are unrelated to the concept of an antidote.
