HESI A2 Practice Vocabulary
1. What does the word 'furnished' mean in the context of the apartment?
- A. Fully renovated
- B. Equipped with furniture
- C. Includes utilities
- D. Has modern decor
Correct answer: B
Rationale: In real estate, when an apartment is described as 'furnished,' it means that it comes equipped with furniture. This typically includes essential items like beds, sofas, dining tables, and more. Therefore, 'Equipped with furniture' is the correct meaning of 'furnished' in this context. Choices A, C, and D are incorrect because being 'furnished' specifically refers to the presence of furniture in the apartment, not renovation status, utilities, or decor style.
2. What is the result of adding 9.43 and 11.3?
- A. 20.73
- B. 21.3
- C. 22
- D. 19.5
Correct answer: A
Rationale: The correct answer is A: 20.73. To calculate the sum of 9.43 and 11.3, you simply add the two numbers together. Therefore, 9.43 + 11.3 equals 20.73. Choice B (21.3) is incorrect because it represents the sum of rounding the numbers up. Choice C (22) and choice D (19.5) are also incorrect as they do not accurately reflect the sum of the provided numbers.
3. Which word in the sentence needs to be corrected for proper grammar?
- A. About it
- B. A
- C. With
- D. Made
Correct answer: B
Rationale: The word 'A' should be corrected to 'an' in the sentence. The sentence should read, 'The nurse made an error with the medication, so the doctor made notes about it in the patient's file.' The article 'an' is used before a noun beginning with a vowel sound, like 'error' in this case. Choices A, C, and D are grammatically correct in the sentence and do not need to be altered.
4. What type of reaction involves atoms attempting to achieve stable electron configurations?
- A. Chemical
- B. Nuclear
- C. Physical
- D. Mechanical
Correct answer: A
Rationale: In a chemical reaction, atoms interact to achieve stable electron configurations through the formation of new chemical bonds or the breaking of existing ones. This process aims to reach a more stable state by filling or emptying electron orbitals, leading to the formation of new substances with more stable configurations. Choice B, nuclear reactions, involve changes in the atomic nucleus rather than electron configurations. Choice C, physical reactions, involve changes in physical state or appearance without changing the chemical makeup. Choice D, mechanical reactions, do not involve the rearrangement of electrons to achieve stable configurations.
5. What is the role of enzymes in the body?
- A. To produce energy
- B. To speed up chemical reactions
- C. To transport molecules
- D. To repair tissues
Correct answer: B
Rationale: Enzymes are biological catalysts that facilitate and speed up chemical reactions in the body. They do not produce energy but enable various processes such as digestion and metabolism by lowering the activation energy required for reactions to occur. Choice A is incorrect because enzymes do not produce energy themselves but assist in energy production through reactions. Choice C is incorrect as enzymes do not primarily function in transporting molecules, although some may have a role in specific transport processes. Choice D is incorrect as the primary role of enzymes is not to repair tissues, but rather to catalyze biochemical reactions.
