HESI A2 Practice Vocabulary
1. Someone who is Altruistic might also be called ______
- A. Selfish
- B. Charitable
- C. Greedy
- D. Hateful
Correct answer: B
Rationale: Altruistic individuals exhibit selfless concern for others, demonstrating a charitable nature. Therefore, being described as charitable aligns with the trait of altruism. Choice A, 'Selfish,' is the opposite of altruistic as it denotes concern only for oneself. Choice C, 'Greedy,' implies a strong desire for more and is not synonymous with altruism. Choice D, 'Hateful,' suggests a feeling of strong dislike, which is not reflective of altruistic behavior.
2. What is the crystalline compound that is a product of protein metabolism known as?
- A. uracil
- B. urine
- C. ureter
- D. urea
Correct answer: D
Rationale: Urea is the correct answer. It is the crystalline compound formed in the liver from the breakdown of proteins, a byproduct of protein metabolism. Urea is excreted by the kidneys in the form of urine, aiding in the elimination of nitrogenous waste from the body. Uracil (Choice A) is a nitrogenous base found in RNA, not a product of protein metabolism. Urine (Choice B) is the liquid waste excreted by the kidneys but not the crystalline compound resulting from protein metabolism. Ureter (Choice C) is a duct that carries urine from the kidneys to the bladder, not the compound produced from protein metabolism.
3. This medication works by inhibiting the action of a certain enzyme. What does inhibiting mean?
- A. Blocking
- B. Hindering
- C. Energizing
- D. Blocking improvement
Correct answer: B
Rationale: The correct answer is 'B: Hindering.' Inhibiting means to hinder or slow down a process. Choices A and D are similar and imply a complete stop of the process rather than just slowing it down. Choice C, 'Energizing,' is the opposite of inhibiting, as it means to provide energy or stimulate rather than hinder.
4. The abbreviation HPV on a medical form refers to a particular ___________.
- A. blood condition

Rationale: The abbreviation HPV stands for Human Papillomavirus, which is a viral infection commonly transmitted through sexual contact. It is known to cause genital warts and various types of cancers, including cervical cancer. Choice A is incorrect because HPV is not related to a blood condition.

5. What does 'Deficit' mean?
- A. An excess of something
- B. A deficiency or lack of something
- C. An abundance of something
- D. A stable amount
Correct answer: B
Rationale: The correct answer is B: 'A deficiency or lack of something.' The term 'deficit' refers to a shortage or inadequacy of something. Choice A is incorrect because a surplus means an excess, which is the opposite of a deficit. Choice C is incorrect as an abundance signifies a large quantity or more than enough of something. Choice D is incorrect as a stable amount does not convey the concept of a deficit.
