Vocabulary HESI A2 Practice Test

Correct Answer: A

Rationale: The correct answer is A: Complaining. Querulous means constantly complaining or irritable. Therefore, a patient who is querulous is likely to be guilty of complaining frequently. The other choices are incorrect because sleeping, shouting, or crying do not directly relate to the behavior of being querulous. Sleeping is unrelated, shouting is more about expressing anger or frustration, and crying is about showing emotion rather than complaining.

Correct Answer: B

Rationale: The correct answer is B: Emetic. An emetic is a medicine that induces vomiting. This is achieved by irritating the stomach lining, leading to the body expelling its contents. A: Laxative helps with bowel movements, not vomiting. C: Vaccine is a substance that stimulates the immune system to produce immunity to a specific disease, not induce vomiting. D: Analgesic is a pain-relieving medication, not used for inducing vomiting.

Correct Answer: B

Rationale: The correct answer is B: A guiding principle. A precept is a fundamental belief or rule guiding behavior. It is not simply a rule (choice A) but a broader guiding principle. It also does not refer to a habit (choice C) or a punishment (choice D), as precepts are more about moral or ethical guidance rather than behavioral patterns or penalties. Overall, the term 'precept' is best defined as a guiding principle due to its foundational and instructive nature.

Correct Answer: A

Rationale: The correct answer is A: fattening. Adding sugar to coffee increases its calorie content, contributing to weight gain if consumed in excess. Choice B: healthy is incorrect as sugar is not a nutritious component. Choice C: rich is subjective and does not relate to the impact of sugar on the coffee. Choice D: flavorful is not directly related to the potential negative health effects of consuming sugar.

Correct Answer: B

Rationale: The correct answer is B: Degree of viscosity, how thick or thin a fluid is. Consistency refers to the thickness or thinness of a fluid, which is directly related to its viscosity. Viscosity is a measure of a fluid's resistance to flow, with thicker fluids having higher viscosity. Color (option A), taste (option C), and smell (option D) are not related to the concept of consistency in fluids. Color is a visual property, taste is a sensory perception, and smell is an olfactory sensation, none of which are indicative of a fluid's consistency.
