HESI A2 Vocabulary 2023

Correct Answer: D

Rationale: The correct answer is D: sternum. The sternum is commonly known as the breastbone in human anatomy. It is a flat bone located in the center of the chest, connecting the rib bones. The term "sternum" is derived from the Greek word "sternon," which means chest. The other choices (A: stelic, B: steres, C: sterol) are not anatomical terms related to the breastbone or chest structure, making them incorrect options in this context.

Correct Answer: B

Rationale: The correct answer is B: viral infection. HPV stands for Human Papillomavirus, a common sexually transmitted infection that can cause genital warts and certain types of cancers. This abbreviation specifically refers to a type of viral infection, not a blood condition (A), heart rate (C), or therapy (D). It is important to understand medical abbreviations to accurately interpret and communicate health information.

Correct Answer: A

Rationale: The correct answer is A: Bitter. Acrid refers to a sharp and unpleasant taste or smell, often associated with bitterness. Bitter is the most synonymous term, as it conveys the same sharp and unpleasant quality. Smoky, nimble, and severe do not align with the definition of acrid, making them incorrect choices. Smoky refers to a smell associated with smoke, nimble relates to agility, and severe conveys seriousness or harshness, none of which capture the essence of acrid. Therefore, option A is the most appropriate synonym for acrid in this context.

Correct Answer: D

Rationale: The correct answer is D: Stoutness. 'Corpulence' means being excessively overweight or obese, which aligns with the patient being difficult to handle due to his size. The other choices are incorrect because: A: Belligerence means aggressiveness, not related to weight. B: Gassiness refers to having excess gas in the digestive system, unrelated to weight. C: Wariness means being cautious or hesitant, not relevant to the context of the sentence.

Correct Answer: A

Rationale: The correct answer is A: Ripple. In this sentence, 'undulate' is used to describe a smooth, wave-like motion of the muscles, which aligns with the meaning of 'ripple.' The word 'undulate' implies a continuous and flowing movement, resembling the gentle and rhythmic movement of waves. The other choices, shake, flatten, and unknot, do not capture the specific fluid and continuous motion described in the sentence. 'Shake' implies a more abrupt and irregular movement, 'flatten' suggests a completely different action of making something flat, and 'unknot' refers to the action of undoing a knot, none of which fit the context of the sentence.
