Vocabulary HESI A2 Practice Test

1. What are the soft spots on the head of a newborn called?

Correct answer: B

Rationale: The correct answer is B: Fontanel. Fontanels are spaces between the bones of a newborn's skull that allow for brain growth and development. The term 'fistula' (choice A) refers to an abnormal passageway between two organs or between an organ and the body surface, not related to newborn soft spots. 'Follicle' (choice C) is a structure in the skin that contains the hair root, not related to the skull. 'Fissure' (choice D) refers to a narrow opening or crack, which is not the term used for the soft spots on a newborn's head.

2. Which law states that matter can neither be created nor destroyed during a chemical reaction?

Correct answer: B

Rationale: The correct answer is B, the Law of Conservation of Mass. This law, formulated by Antoine Lavoisier, states that matter cannot be created or destroyed in a chemical reaction. It is a fundamental principle in chemistry that explains the preservation of mass during chemical reactions, indicating that the total mass of the reactants is equal to the total mass of the products. The other choices are incorrect because: A: The Law of Conservation of Energy states that energy cannot be created or destroyed, not matter. C: The Law of Constant Composition refers to compounds having the same composition by mass regardless of their source or how they were prepared, not about the conservation of matter in reactions. D: The Law of Multiple Proportions describes the ratios in which elements combine to form compounds, not the conservation of mass.

3. What is a Contraindication?

Correct answer: B

Rationale: A contraindication is a specific situation in which a drug, procedure, or treatment should not be used because it may be harmful. Choice A is incorrect because a contraindication advises against performing an action. Choice C is incorrect as it refers to a precaution regarding side effects rather than a reason not to proceed. Choice D is incorrect because a contraindication does not advise the use of something.

4. What is the meaning of the word diminished as used in the passage about Concussions?

Correct answer: B

Rationale: In this context, "diminished" means reduced. Substituting the other choices into the sentence does not make sense contextually, whereas "reduced" fits appropriately, confirming B as the correct answer.

5. The C in C-section stands for ___________.

Correct answer: B

Rationale: The correct answer is B: Caesarean. The C in C-section stands for 'Caesarean' after Julius Caesar, who was rumored to have been born via this surgical procedure. The term 'Caesarean' is derived from the Latin word 'caesus,' meaning cut or incised. Choice A, Carthusian, is incorrect as it does not relate to childbirth. Choice C, Cartesian, is unrelated to the medical procedure. Choice D, Caedmon, is also irrelevant in the context of C-sections.
