Vocabulary HESI A2 Practice Test

Correct Answer: B

Rationale: The correct answer is B: Complaining. Querulous means constantly complaining or expressing dissatisfaction. This is because the word is derived from the Latin word "queri" which means to complain. Shouting (A), crying (C), and praising (D) do not align with the definition of querulous. Shouting is about making a loud noise, crying is about expressing sadness or distress, and praising is about expressing approval or admiration. Therefore, B is the most appropriate choice that accurately reflects the meaning of querulous.

Correct Answer: B

Rationale: The correct answer is B: Exhausted. Lethargy is a state of extreme tiredness or fatigue, often leading to a lack of energy and motivation. A lethargic individual would exhibit signs of exhaustion rather than being energetic, confused, or restless. Being lethargic implies a lack of physical or mental energy, making the individual more likely to appear exhausted than any other option.

Correct Answer: B

Rationale: The correct answer is B: To begin or put into practice. 'Initiate' means to start something or set a process in motion. This is the correct answer because it accurately reflects the definition of the word. The other choices are incorrect because A: To finish is the opposite of 'initiate', C: To delay is the opposite of starting something, and D: To stop completely is also the opposite of initiating something.

Correct Answer: B

Rationale: The correct answer is B: Larynx. The larynx is commonly known as the voice box because it houses the vocal cords responsible for producing sound. It is located at the top of the trachea and plays a crucial role in speech and breathing. The other choices are incorrect because the trachea (A) is the windpipe, the pharynx (C) is the throat, and the esophagus (D) is the tube that carries food to the stomach. The larynx is specifically associated with vocalization and sound production.

Correct Answer: C

Rationale: The correct answer is C: Flexible. A flexible tube would be most suitable for navigating through a curved pipe as it can bend and adapt to the shape of the pipe, allowing the plumber to maneuver easily. A solid tube (choice A) would not be able to bend, making it difficult to navigate through curves. A rigid tube (choice B) may also have difficulty navigating bends as it is not flexible. Perforated tubes (choice D) have holes and are not suitable for navigation through pipes. In summary, the flexibility of the tube is crucial for navigating through curved pipes efficiently.
