HESI A2 Practice Test Vocabulary

Correct Answer: C

Rationale: The correct answer is C: Flexible. The plumber used a flexible tube because it can bend and conform to the shape of the curved pipe, making it easier to navigate through the twists and turns. A solid or rigid tube would not be able to maneuver through the curved pipe effectively. Perforated tube has holes and would not be suitable for clearing blockages. In summary, the flexibility of the tube allows it to adapt to the shape of the pipe, making it the most appropriate choice for this task.

Correct Answer: A

Rationale: The correct answer is A: Toxic. "Injurious" means causing harm or damage. Toxic substances can cause harm to living organisms, making them the best fit for the word. Palatable means pleasant to taste, amenable means willing to agree, and harmless means not causing harm, which do not align with the meaning of injurious.

Correct Answer: C

Rationale: The correct answer is C: Easiest. In this sentence, the superlative form "the" is used before the adjective "easiest" to indicate the highest degree of comparison. "Most easiest" (A) is incorrect as "most" is redundant with the superlative form. "Most easy" (B) is incorrect as "easy" should be in the superlative form. "Easy" (D) is incorrect as it is not in the superlative form needed for this context.

Correct Answer: B

Rationale: The term 'residual' refers to what is left behind or remaining after a process. In the context of the sentence, it specifically refers to the urine left in the patient's bladder after voiding. Therefore, choice B, "What is left," is the correct answer. Choice A, "Measurement," is incorrect because 'residual' does not refer to the act of measuring but rather to the remaining amount. Choice C, "Total volume," is incorrect as it does not specifically address what is left behind. Choice D, "Color and clarity," is also incorrect as 'residual' does not pertain to the characteristics of the urine but rather to the quantity remaining.

Correct Answer: C

Rationale: The correct answer is C: Hold fast. Adhere means to stick firmly to something. In this context, "hold fast" best captures the idea of maintaining a strong attachment or connection. Choice A, remain intact, does not convey the idea of sticking or clinging. Choice B, loosen, is the opposite of adhere. Choice D, position next to, does not capture the concept of sticking or adhering to something. Therefore, choice C is the most appropriate synonym for adhere in this context.
