Vocabulary HESI A2 Practice Test

Correct Answer: A

Rationale: The correct answer is A: Widespread. Ubiquitous means something that is present or found everywhere. This word conveys the idea of being widespread or omnipresent. The other choices are incorrect because B: Miniscule means very small, C: Invalid means not valid or acceptable, and D: Unit refers to a single entity or a distinct part. Therefore, only choice A aligns with the definition of ubiquitous.

Correct Answer: B

Rationale: The correct answer is B: Continuous. 'Ongoing' refers to something that is continuing or in progress without interruption. It does not mean 'Ended' (A), 'Delayed' (C), or 'Occasional' (D). These options do not align with the definition of ongoing, which implies a continuous and uninterrupted state. Therefore, choice B is the most appropriate based on the meaning of the term 'Ongoing'.

Correct Answer: A

Rationale: The correct answer is A: patient. In this sentence, the word "patient" is misspelled as "paitent." The correct spelling should be "patient." The other choices (B: physician, C: sodium, D: recommended) are all spelled correctly and are relevant to the context of the sentence. Therefore, the correct answer is A as it is the only word that is misspelled in the given sentence.

Correct Answer: B

Rationale: The correct answer is B: Degree of viscosity, how thick or thin a fluid is. Consistency refers to the thickness or thinness of a fluid, which is directly related to its viscosity. Viscosity is a measure of a fluid's resistance to flow, with thicker fluids having higher viscosity. Color (option A), taste (option C), and smell (option D) are not related to the concept of consistency in fluids. Color is a visual property, taste is a sensory perception, and smell is an olfactory sensation, none of which are indicative of a fluid's consistency.

Correct Answer: A

Rationale: The correct answer is A: shelter. Children depend on their parents for providing a safe and secure place to live, which includes shelter from the elements. This is a basic necessity for their well-being and development. Choice B, security, is related but not as essential as shelter. Choice C, guidance, and choice D, affection, are important aspects of parenting but do not directly address the basic need for shelter. Therefore, the correct answer is A as it directly fulfills a fundamental requirement for children's survival and growth.
