HESI A2 Practice Test Vocabulary

Correct Answer: A

Rationale: The correct answer is A: Undesirable. In the context of the sentence, 'adverse' refers to negative or harmful effects. The word 'adverse' is commonly used to describe something that is unfavorable or harmful. In this case, the man is experiencing negative side effects from his medication, making 'undesirable' the most fitting interpretation. Incorrect Choices: B: Frequent - Frequency is not the primary meaning of 'adverse' in this context. C: Noticeable - While side effects may be noticeable, 'adverse' implies more than just being noticeable. D: Constant - 'Adverse' does not necessarily mean constant, it means unfavorable or harmful.

Correct Answer: B

Rationale: The correct answer is B: Reason. 'Rational' is related to reason, logic, and sound judgment. It implies making decisions based on logical thinking rather than emotions. Angry (A) does not relate to 'rational.' Rodent (C) and Proportion (D) are also unrelated to the meaning of 'rational.'

Correct Answer: A

Rationale: The correct answer is A: Chronology. Chronology refers to the arrangement of events in the order of their occurrence. This term is specifically used to describe the chronological sequence of events. Notation (B) refers to symbols or marks used to represent something, not the order of events. Documentation (C) refers to the process of recording or providing evidence, not necessarily in chronological order. Helicon (D) is a term not related to the order of events. Therefore, A is the correct answer as it directly relates to the description of events in the order of their occurrence.

Correct Answer: A

Rationale: The correct answer is A: Prefix. A prefix is a word part placed before a base word to change its meaning. It comes before the root word and alters its definition. Prefixes are essential in forming new words and expanding vocabulary. Choice B: Affix is a broad term that refers to both prefixes and suffixes. While technically correct, it is not as specific as prefix in this context. Choice C: Suffix is a word part placed after a base word to change its meaning. It is the opposite of a prefix. Choice D: Vocab is short for vocabulary and does not relate to the word part placed before a word to change its meaning.

Correct Answer: A

Rationale: The correct answer is A: Protective device. A cast is a rigid protective device used to immobilize and support a broken or injured limb during the healing process. The nurse assisted in the removal of the cast, which indicates it was a protective device. The other choices (B: Medicated sleeve, C: Sling, D: Bandage) do not accurately describe a cast and its purpose in immobilizing and supporting a limb. A cast is not a sleeve with medication, a sling for support, or a simple bandage for wound protection.
