HESI A2 Vocabulary 2023

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 term 'superior' in anatomy refers to a structure being located above another structure. In the human body, 'superior' typically refers to the top part. For example, the head is superior to the neck. Therefore, the correct answer is A: Top. - B: Bottom is incorrect as 'inferior' is used to refer to the lower part. - C: Front is incorrect as 'anterior' is used to describe the front part. - D: Back is incorrect as 'posterior' is used to describe the back part.

Correct Answer: A

Rationale: The correct answer is A: eyelid. A stye, also known as a hordeolum, is an infection of the eyelid caused by bacteria. It typically forms near the base of the eyelash due to a blocked oil gland. Symptoms include redness, swelling, and pain. The other choices (B, C, D) are incorrect because a stye specifically affects the eyelid and not the eardrum, nostril, or scalp. Each of these areas has its own distinct conditions and infections unrelated to a stye.

Correct Answer: B

Rationale: The correct answer is B: quite stubborn. "Obdurate" means stubborn or refusing to change one's opinion or course of action. Therefore, a patient who is especially obdurate would be characterized as being quite stubborn. The other choices are incorrect because being obdurate does not necessarily have any direct correlation with being very large (A), easily upset (C), or ready to go home (D). It specifically refers to being stubborn or resistant to change, making choice B the most fitting description.

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.
