HESI A2 Practice Test Vocabulary
1. Which word best defines the term 'accountable' as used in the following sentence? 'The night nursing staff is accountable for those records.'
- A. Receptive
- B. Notorious
- C. Responsible
- D. Preoccupied with
Correct answer: C
Rationale: The correct answer is C, 'Responsible.' In this context, 'accountable' means being held answerable or responsible for something. The night nursing staff is responsible for maintaining and managing those records. Choice A, 'Receptive,' does not accurately capture the meaning of 'accountable' in this context. Being receptive means being open to new ideas or suggestions, which is not the intended meaning here. Choice B, 'Notorious,' is incorrect as it means famous or well-known for something negative, which is not related to being accountable or responsible. Choice D, 'Preoccupied with,' is also incorrect. 'Preoccupied with' means being excessively concerned or worried about something, which does not align with the meaning of 'accountable' in this sentence.
2. What is Diffusion?
- A. Movement of materials from low concentration to high concentration
- B. Movement of materials from high concentration to low concentration
- C. Absorption of nutrients
- D. Breaking of materials
Correct answer: B
Rationale: Diffusion is the process where substances move from an area of high concentration to an area of low concentration. This movement occurs due to the random motion of particles and continues until equilibrium is reached. Choice A is incorrect because diffusion occurs down the concentration gradient, from high to low concentration, not from low to high concentration. Choice C is incorrect as it refers to the uptake of substances by cells, not the general process of diffusion. Choice D is incorrect as it does not accurately describe the process of diffusion; diffusion involves the movement of substances, not the breaking of materials.
3. What does Manifestation mean?
- A. A symptom or sign of a condition
- B. An indication or sign of a condition
- C. A treatment plan
- D. A type of diagnosis
Correct answer: B
Rationale: Manifestation means an indication or sign of a condition. It is not a treatment plan (choice C) or a type of diagnosis (choice D). While choice A is close, 'symptom' is more specific than 'indication' in this context, making choice B the most accurate.
4. A patient who is lethargic may seem _____?
- A. Energetic
- B. Exhausted
- C. Confused
- D. Restless
Correct answer: B
Rationale: The correct answer is B: 'Exhausted.' Lethargic describes a state of feeling sluggish, tired, and lacking energy, which aligns with being exhausted. Choice A, 'Energetic,' is the opposite of lethargic and does not fit the description. Choice C, 'Confused,' refers to a state of disorientation rather than physical tiredness. Choice D, 'Restless,' implies a state of agitation or inability to relax, which contrasts with the typical presentation of someone who is lethargic.
5. A paroxysm is a sudden spasm. Another word for this might be ___________.
- A. convulsion
- B. symptom
- C. efficacy
- D. embolism
Correct answer: A
Rationale: The correct answer is A: "convulsion." A paroxysm is defined as a sudden spasm or convulsion. The word "convulsion" specifically refers to a violent and involuntary contraction or spasm of muscles, which aligns perfectly with the description of a paroxysm. On the other hand, choices B, C, and D are incorrect. "Symptom" (B) refers to a manifestation of a condition rather than a physical spasm. "Efficacy" (C) relates to effectiveness or success, not a sudden spasm. "Embolism" (D) refers to the obstruction of a blood vessel, which is unrelated to the concept of a sudden spasm. Therefore, convulsion is the most suitable synonym for a paroxysm in this context.
