Quizlet Vocabulary HESI A2
1. What is the term for the lower surface of a structure?
- A. Inferior
- B. Transverse
- C. Dorsal
- D. Ventral
Correct answer: D
Rationale: The term for the lower surface of a structure is 'ventral.' 'Ventral' is used in anatomy to describe the front or lower surface of an organism or structure. In this context, 'inferior' (choice A) is not the correct term as it generally refers to something being below or lower in position but not specifically the lower surface of a structure. 'Transverse' (choice B) refers to a crosswise direction, not the lower surface. 'Dorsal' (choice C) is the term used for the upper or back surface of an organism or structure, opposite to the ventral surface.
2. It's true that children depend on their parents for food, clothing, and ______.
- A. shelter
- B. security
- C. guidance
- D. affection
Correct answer: A
Rationale: Children depend on their parents for providing basic needs like food, clothing, and shelter. 'Shelter' refers to the physical protection and housing that parents are responsible for providing to their children. While security, guidance, and affection are also important aspects of parenting, in the context of the question, the most essential need after food and clothing is shelter.
3. What is the crystalline compound that is a product of protein metabolism known as?
- A. uracil
- B. urine
- C. ureter
- D. urea
Correct answer: D
Rationale: Urea is the correct answer. It is the crystalline compound formed in the liver from the breakdown of proteins, a byproduct of protein metabolism. Urea is excreted by the kidneys in the form of urine, aiding in the elimination of nitrogenous waste from the body. Uracil (Choice A) is a nitrogenous base found in RNA, not a product of protein metabolism. Urine (Choice B) is the liquid waste excreted by the kidneys but not the crystalline compound resulting from protein metabolism. Ureter (Choice C) is a duct that carries urine from the kidneys to the bladder, not the compound produced from protein metabolism.
4. An alarm that is strident is ___________.
- A. shrill
- B. muted
- C. constant
- D. resonant
Correct answer: A
Rationale: A strident alarm is loud, harsh, and piercing. The word 'shrill' specifically denotes a high-pitched and piercing sound, which aligns well with the characteristics of a strident alarm. Therefore, 'shrill' is the most suitable answer in this context. Choices B, C, and D are incorrect because a strident alarm is not quiet (muted), unchanging (constant), or deep and full (resonant), but rather loud and harsh.
5. The abbreviation DTs on a patient’s chart stands for ___________.
- A. deep tendon reflex
- B. descending thorax
- C. delirium tremens
- D. dextrose in water
Correct answer: C
Rationale: The abbreviation DTs on a patient's chart stands for delirium tremens, which is a severe form of alcohol withdrawal. Symptoms of delirium tremens include confusion, hallucinations, severe agitation, seizures, and autonomic instability. This condition requires prompt medical treatment to prevent serious complications. Choices A, B, and D are incorrect. Deep tendon reflex (A) refers to the reflex response elicited by tapping a tendon with a reflex hammer, descending thorax (B) is not a recognized medical term, and dextrose in water (D) is a solution used for various medical purposes but is not represented by the abbreviation DTs.
