HESI A2 Vocabulary Quiz

Correct Answer: D

Rationale: The correct answer is D: urea. Urea is the crystalline compound produced during protein metabolism in the liver. It is excreted in urine. Uracil (A) is a nitrogenous base found in RNA, not a product of protein metabolism. Urine (B) is the liquid waste excreted by the kidneys, not a specific compound. Ureter (C) is a tube that carries urine from the kidneys to the bladder, not a product of protein metabolism. Therefore, urea is the correct answer as it directly relates to protein metabolism and its excretion in urine.

Correct Answer: B

Rationale: The correct answer is B: A type of lipoprotein. LDL stands for Low-Density Lipoprotein, which is a type of cholesterol-carrying particle in the blood. It is often referred to as the "bad" cholesterol because high levels can lead to plaque buildup in arteries. Choice A is incorrect as LDL is not related to denominations. Choice C is incorrect as LDL is not related to self-care mobility skills. Choice D is incorrect as LDL is not a certain digital value.

Correct Answer: C

Rationale: The correct answer is C: Emit. In the sentence provided, the word "vent" is used in the context of releasing or letting out gases to the outside. Therefore, the meaning of "vent" in this sentence is to emit or release. The other choices are incorrect because: A: Block - This does not fit the context of the sentence as vent does not mean to block in this case. B: Trade - This does not make sense in the given context as vent does not refer to trading. D: Inhale - This is the opposite of the correct meaning in the context of the sentence, as vent means to release gases outward, not inhale them.

Correct Answer: C

Rationale: The correct answer is C: Hindering. Inhibiting means to restrain or prevent, which fits the context of the sentence where the medication is stopping the action of an enzyme. Choice A, Occupying, is incorrect because inhibiting does not involve taking up space. Choice B, Speeding, is incorrect as inhibiting means slowing down or preventing, not increasing speed. Choice D, Enhancing, is incorrect as inhibiting is the opposite of enhancing, which means to improve or increase. Therefore, the most suitable meaning for inhibiting in this context is hindering.

Correct Answer: D

In the context of the sentence, the substance breaks down into smaller pieces in the mouth for easy swallowing. A: Evaporates means turning into vapor, not applicable here. B: Fizzes means bubbling or hissing sound, not related to breaking into pieces. C: Deviates means to depart from a standard or path, not relevant to the context.
