TEAS Test 7 science quizlet

1. Which property of a substance refers to its ability to be stretched into thin wires?

Correct answer: C

Rationale: Ductility is the property of a substance that allows it to be stretched into thin wires without breaking. It is a crucial property for materials used in wire production. Conductivity refers to the ability of a substance to conduct electricity or heat, not to be stretched into wires. Viscosity is the measure of a fluid's resistance to flow, not its ability to be stretched. Malleability is the property of a substance that allows it to be hammered or rolled into thin sheets, not stretched into wires.

2. Which layer of the skin, containing connective tissue, blood vessels, and nerve endings, is located beneath the epidermis?

Correct answer: B

Rationale: The correct answer is the dermis. The dermis is the deeper layer of the skin that contains connective tissue, blood vessels, and nerve endings. It is located beneath the epidermis and provides structural support, nourishment, and sensitivity to the skin. The epidermis is the outermost layer of the skin responsible for protection. The hypodermis, also known as the subcutaneous layer, is the deepest layer that contains fat cells and plays a role in insulation and energy storage. The stratum corneum is the outermost layer of the epidermis composed of dead skin cells that are continually shed and replaced.

3. In which position allows access to the stomach?

Correct answer: B

Rationale: The question now specifies the need for a position that allows access to the stomach. The correct answer is 'B: Prone.' In the prone position, the patient lies face down, which facilitates access to the stomach for various procedures or examinations. Choice A, 'Medial,' refers to a direction rather than a patient position. Choice C, 'Superficial,' describes a superficial depth rather than a patient position. Choice D, 'Supine,' is a position where the patient lies face up, which does not provide easy access to the stomach.

4. What type of bond is formed when electrons are transferred between atoms?

Correct answer: D

Rationale: The correct answer is 'D: Ionic bond.' An ionic bond is formed when electrons are transferred between atoms. In an ionic bond, one atom donates electrons to another atom, resulting in the formation of positively and negatively charged ions that are attracted to each other, creating a strong bond. Choice A, 'Transfer bond,' is incorrect because there is no common term known as a 'Transfer bond' in chemistry. Choice B, 'Static bond,' is incorrect as it does not describe the process of electron transfer between atoms. Choice C, 'Covalent bond,' is incorrect because in a covalent bond, electrons are shared between atoms rather than transferred outright, making it different from an ionic bond.

5. What is the technical term for the free edges of your fingernails and toenails?

Correct answer: C

Rationale: The correct answer is C, hyponychium. The hyponychium is the skin under the free edge of the nail, responsible for sealing the nail to the fingertip and protecting the nail bed from bacteria and debris. The lunula (choice A) refers to the white crescent moon shape at the base of the nail. The matrix (choice B) is the area under the nail where new nail cells are produced. The free edge (choice D) is the part of the nail that extends beyond the fingertip or toe.
