HESI A2 Vocabulary Quizlet

Correct Answer: C

Rationale: The correct answer is C: essential. In the context of the sentence, 'vital' means absolutely necessary or crucial for the victim's well-being. The word 'vital' emphasizes the critical importance of receiving immediate medical attention. It conveys the sense of urgency and importance in this situation. Incorrect choices: A: recommended - This choice suggests something that is advised but not necessarily crucial. It does not capture the urgent nature of the situation as conveyed by 'vital'. B: discouraged - This choice means the opposite of what 'vital' conveys. It implies that receiving medical attention is not desirable, which is not the case in the given sentence. D: sufficient - This choice implies that receiving medical attention is enough, but 'vital' goes beyond being just enough; it emphasizes the absolute necessity of immediate medical attention.

Correct Answer: B

Rationale: The correct answer is B: unnecessary. The word 'unnecessary' is misspelled as 'unneccessary' in the sentence. The correct spelling should have only one 'c' instead of two. The other choices are spelled correctly - A: physician, C: explain, and D: procedure. 'Physician' refers to a medical doctor, 'explain' means to make something clear, and 'procedure' is a series of steps to be followed. Thus, the misspelling in choice B makes it the correct answer.

Correct Answer: C

Rationale: The correct answer is C: pugnacious. Belligerent means hostile and aggressive, which aligns with the definition of pugnacious. Retired (A) means no longer working, sardonic (B) means mocking, and acclimated (D) means adjusted to new conditions, none of which capture the aggressive nature of 'belligerent'.

Correct Answer: B

Rationale: The correct answer is B: Difficult to arouse. Lethargy refers to extreme tiredness or a lack of energy, causing the patient to be difficult to arouse. Pacing the halls (A) indicates restlessness, shaking uncontrollably (C) indicates tremors, and not responding to pain (D) indicates unconsciousness, none of which are characteristic of lethargy.

Correct Answer: A

Rationale: The correct answer is A: ilium. The ilium is one of the three bones that make up the hip bone (along with the ischium and pubis). It is the largest and most superior portion of the hip bone. The lateral portion of the hip bone is indeed the ilium. Choice B: ileum is incorrect because the ileum is part of the small intestine, not a bone in the hip. Choice C: icterus is incorrect because it refers to a medical condition characterized by yellowing of the skin and eyes, not a bone in the hip. Choice D: ileus is incorrect because it is a medical term that refers to a blockage in the intestines, not a bone in the hip.
