Vocabulary HESI A2 Practice Test

Correct Answer: B

Rationale: The correct answer is B because hygiene refers to practices that promote cleanliness and good health. This includes actions such as handwashing, proper sanitation, and personal grooming. Option A is close but doesn't emphasize the preventive aspect. Option C is incorrect as hygiene is not specifically related to dietary health. Option D is incorrect as hygiene is not a type of infection but rather a set of practices to prevent infections.

Correct Answer: B

Rationale: The correct answer is B: To begin or put into practice. 'Initiate' means to start something or set a process in motion. This is the correct answer because it accurately reflects the definition of the word. The other choices are incorrect because A: To finish is the opposite of 'initiate', C: To delay is the opposite of starting something, and D: To stop completely is also the opposite of initiating something.

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: 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.

Correct Answer: D

Rationale: The correct answer is D: Ruminate. To ruminate means to think deeply about something before making a decision. This word specifically implies a process of careful consideration and reflection. Choice A, imply, means to suggest indirectly and does not convey the idea of thoughtful consideration. Choice B, transgress, means to violate a rule or boundary, which is unrelated to thinking before making a decision. Choice C, allay, means to alleviate or calm, which is not related to the act of thinking before deciding. Therefore, only choice D, ruminate, aligns with the concept of contemplating before making a decision.
