HESI A2 Practice Test Vocabulary

Correct Answer: A

Rationale: The correct answer is A: Toxic. "Injurious" means causing harm or damage. Toxic substances can cause harm to living organisms, making them the best fit for the word. Palatable means pleasant to taste, amenable means willing to agree, and harmless means not causing harm, which do not align with the meaning of injurious.

Correct Answer: C

Rationale: Rationale: 1. 'Impervious' means not affected or unaffected by something. 2. In the given sentence, it implies that the subject is not impacted by something. 3. Choices A, B, and D do not align with the meaning of 'impervious.' 4. Choice A suggests coping well, which is different from being unaffected. 5. Choice B implies enjoyment, unrelated to being unaffected. 6. Choice D suggests being very sensitive, opposite to being impervious.

Correct Answer: D

Rationale: The correct answer is D: Ventral. In anatomy, ventral refers to the front or lower surface of a structure. This term is commonly used to describe the underside of an organism or an anatomical feature. In this context, the lower surface of a structure is typically referred to as the ventral side. The other choices, A: Inferior, B: Transverse, and C: Dorsal, are incorrect in this context as they do not specifically refer to the lower surface of a structure. Inferior refers to being below or lower in position, transverse refers to being situated across something, and dorsal refers to the back or upper surface of a structure.

Correct Answer: C

Rationale: Step-by-step rationale for choice C (Parasite) being correct: 1. A nit is the egg of a louse, which is a parasite that infests the hair or body. 2. Parasites are organisms that live on or in another organism (host) for nourishment. 3. Nits are commonly associated with head lice infestations. 4. Therefore, the correct answer is C (Parasite). Summary of why other choices are incorrect: - Abscess (A): An abscess is a localized collection of pus within tissues, not related to nits. - Bandage (B): Bandage is a material used for covering wounds, not related to nits. - Infection (D): Infection refers to invasion and multiplication of pathogens in the body, not specific to nits.

Correct Answer: A

Rationale: The correct answer is A: She. In this sentence, "Nurse Junko and she" is the subject performing the action. When using a compound subject, the subjective pronoun "she" must be used to refer to Nurse Junko. The subjective pronoun "she" is used for third person singular subjects, while "her" would be used for the object form. Choices B, C, and D are incorrect because they do not match the subject-verb agreement in the sentence. "Them" is plural, "Me" is first person singular, and "Him" is third person singular object form.
