HESI A2
Vocabulary for HESI A2
1. What does oral mean?
- A. Through the skin
- B. Given through or affecting the mouth
- C. Injected
- D. Absorbed through digestion
Correct answer: B
Rationale: The correct answer is B: 'Given through or affecting the mouth.' Oral medications are those that are taken by mouth. Choice A is incorrect as 'Through the skin' refers to something being absorbed through the skin, not through the mouth. Choice C, 'Injected,' is incorrect as oral administration does not involve injection but rather ingestion. Choice D, 'Absorbed through digestion,' is partially correct in that oral medications are indeed absorbed through the digestive system, but the term 'oral' specifically refers to the mouth in this context.
2. 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.
3. The jawbone may be called the ___________.
- A. mantis
- B. mantua
- C. mandible
- D. manganite
Correct answer: C
Rationale: The jawbone is commonly referred to as the mandible in anatomy. It is the largest and strongest bone in the human face and forms the lower jaw, holding the lower teeth in place. "Mandible" is the correct anatomical term for this specific bone structure.
4. What is the meaning of Diameter?
- A. The width of a structure
- B. The distance across the center of an object
- C. The height of an object
- D. The radius of a circle
Correct answer: B
Rationale: The correct answer is B. Diameter is defined as the distance across the center of an object, typically a circle. Choice A is incorrect because width refers to the measurement of something from side to side, not necessarily through the center. Choice C is incorrect because height is a measurement from top to bottom, not across the center. Choice D is incorrect because the radius of a circle is the distance from the center to any point on the circle's circumference, not the distance across the center.
5. 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.
