HESI A2 Vocabulary 2024
1. What is the meaning of verified?
- A. Belittled
- B. Confirmed
- C. Anecdotal
- D. Implicit
Correct answer: B
Rationale: Verified means confirmed or proven to be true. When something is verified, it has been established as factual or accurate through thorough examination or evidence. It is the opposite of belittled, anecdotal, or implicit, as those terms do not convey the sense of confirmation or validation that verified does.
2. What is the meaning of Gender?
- A. A medical condition
- B. Sex of an individual
- C. Emotional state
- D. A psychological term
Correct answer: B
Rationale: Gender refers to the biological and social characteristics that define male and female identities. It is not a medical condition, emotional state, or psychological term. The term 'gender' specifically relates to the sex of an individual, distinguishing between traits associated with being male or female. Therefore, the correct answer is B.
3. Which part of the nervous system includes the femoral, radial, and ulnar nerves?
- A. Somatic
- B. Autonomic
- C. Sympathetic
- D. Parasympathetic
Correct answer: A
Rationale: The correct answer is A: Somatic. The femoral, radial, and ulnar nerves are all part of the somatic nervous system, responsible for controlling voluntary movements and sensory input. These nerves innervate muscles and skin throughout the body, allowing conscious control of movements and sensations. The somatic nervous system is distinct from the autonomic nervous system, which regulates involuntary bodily functions. Choices B, C, and D are incorrect because the autonomic nervous system (B) is responsible for involuntary functions, while the sympathetic (C) and parasympathetic (D) divisions are subdivisions of the autonomic nervous system, not the somatic nervous system.
4. Convert 3/8 to a decimal.
- A. 0.25
- B. 0.25
- C. 0.3
- D. 0.375
Correct answer: D
Rationale: To convert 3/8 to a decimal, divide 3 by 8: 3 รท 8 = 0.375. The correct answer is 0.375. Choice A (0.25), Choice B (0.25), and Choice C (0.3) are incorrect because they do not represent the equivalent decimal value of 3/8.
5. During protein synthesis, what process uses an RNA strand to produce a complementary strand of DNA?
- A. Transcription
- B. Translation
- C. Transfer synthesis
- D. Codon synthesis
Correct answer: A
Rationale: The correct answer is 'Transcription.' During transcription, an RNA strand is used to produce a complementary strand of DNA. This process is essential for converting the genetic information stored in DNA into RNA. Choice B, 'Translation,' is incorrect as it involves the synthesis of proteins from mRNA. Choice C, 'Transfer synthesis,' is not a recognized term in molecular biology. Choice D, 'Codon synthesis,' is also incorrect as it does not refer to the process of using an RNA strand to produce a complementary DNA strand.
