HESI A2 Vocabulary 2024
1. What is the meaning of the word 'placebo' in the following sentence: 'Ten patients will receive the experimental drug while 10 take a placebo'?
- A. Fallback
- B. Substitute
- C. Control
- D. Curative
Correct answer: C
Rationale: In the context of the sentence, the word 'placebo' refers to a substance or treatment that resembles a real medical treatment but has no therapeutic effect. It is used as a standard against which the effects of the experimental drug are compared. A placebo is typically included in a control group in medical research to evaluate the actual effects of the experimental drug. Therefore, in this scenario, the placebo serves as a control to gauge the effectiveness of the experimental drug, making choice C the correct answer. Choices A, B, and D are incorrect because a placebo is not a fallback, substitute, or curative treatment in this context.
2. What does Gaping mean?
- A. Partially closed
- B. Wide open
- C. Narrow
- D. Sealed
Correct answer: B
Rationale: The correct answer is B, 'Wide open'. Gaping refers to something being wide open, not partially closed (choice A), narrow (choice C), or sealed (choice D). In the context of the question, 'Gaping' describes something that is open widely.
3. Select the meaning of the underlined word in the following sentence. The children became bellicose after too much time in the moving car.
- A. Beautiful
- B. Selfless
- C. Tolerant
- D. Quarrelsome
Correct answer: D
Rationale: The word 'bellicose' means showing aggression or a willingness to fight. In the context of the sentence, it suggests that the children became argumentative or confrontational after spending too much time in the moving car. Therefore, the correct meaning is 'quarrelsome.' Choices A, B, and C are incorrect because 'bellicose' does not mean beautiful, selfless, or tolerant. It specifically refers to a combative or aggressive behavior, which aligns with 'quarrelsome.'
4. What is another word for toxin?
- A. Impurity
- B. Element
- C. Remedy
- D. Poison
Correct answer: D
Rationale: The correct answer is D, Poison. A toxin is a harmful substance that can cause illness or death, and poison is a synonym commonly used to refer to such substances. Choices A, B, and C are incorrect because impurity refers to something being dirty or unclean, an element is a pure substance that cannot be broken down further, and a remedy is a solution or treatment for a problem, not a harmful substance like a toxin.
5. Choose the best description for the term 'selected plants' in the following sentence: 'Saturated fat comes principally from animal food products and selected plants.'
- A. Plants that have been chosen
- B. Particular plants
- C. Top quality plants
- D. Restricted plants
Correct answer: B
Rationale: The term 'selected plants' in this sentence refers to specific or particular plants that have been chosen intentionally for some reason. It implies that not all plants contribute to saturated fat but only specific ones. The term 'particular plants' best captures this meaning in the context provided. Choices A, C, and D are incorrect because 'selected plants' does not necessarily imply they are of top quality, plants that have been restricted, or chosen without reason. The emphasis is on the specificity of the plants chosen, making 'particular plants' the most suitable description.
