HESI A2 Vocabulary 2023
1. What is your “funny bone” actually?
- A. Humerus
- B. Ulnar nerve
- C. Carpal bone
- D. Biceps brachii
Correct answer: B
Rationale: Your 'funny bone' is actually your ulnar nerve, not a bone. The ulnar nerve runs along the inside part of your elbow and is easily bumped or compressed, leading to a tingling or slightly painful sensation that is commonly referred to as hitting your funny bone. The humerus (Choice A) is the long bone in your upper arm, the carpal bone (Choice C) is a bone in your wrist, and the biceps brachii (Choice D) is a muscle in your upper arm. Therefore, the correct answer is the ulnar nerve (Choice B).
2. Choose the meaning of the word 'intramuscularly' in the following sentence: 'This vaccine must only be used intramuscularly and as a single-dose vial.'
- A. Between muscles
- B. Into muscles
- C. Without muscles
- D. On top of muscles
Correct answer: B
Rationale: The word 'intramuscularly' in the sentence indicates that the vaccine should be used by injection directly into the muscles. This means the correct meaning is 'into muscles,' making option B the most suitable choice. Choices A, C, and D are incorrect because 'intramuscularly' specifically refers to administering something inside the muscle, not between muscles, without muscles, or on top of muscles.
3. What does Flaccid mean?
- A. Rigid
- B. Limp or lacking tone
- C. Tense
- D. Swollen
Correct answer: B
Rationale: The correct answer is B: 'Limp or lacking tone.' Flaccid refers to something that is lacking firmness or muscle tone. Choice A, 'Rigid,' is incorrect as it is the opposite of flaccid. Choice C, 'Tense,' is also incorrect as it implies stiffness or tightness, which is different from being flaccid. Choice D, 'Swollen,' is unrelated to the meaning of flaccid.
4. What does Nebulous mean?
- A. Clear
- B. Vague
- C. Distinct
- D. Complex
Correct answer: B
Rationale: The correct answer is B: 'Vague.' Nebulous means something that is vague or unclear. Choices A, C, and D are incorrect because nebulous is the opposite of clear, distinct, and complex. Nebulous refers to something lacking definite form or limits, making it difficult to understand or perceive clearly.
5. HPV is likely to involve the ___________.
- A. skull and spine
- B. mucous membranes
- C. kidneys
- D. heart
Correct answer: B
Rationale: HPV, which stands for Human Papillomavirus, is a virus that commonly affects the skin and mucous membranes. It primarily targets the genital area but can also infect the mouth and throat through oral-genital contact. Therefore, the most likely involvement of HPV is with the mucous membranes, making option B the correct choice. Choices A, C, and D are incorrect because HPV does not typically affect the skull, spine, kidneys, or heart.
