Nursing Elites

1. Specialized cell types organized in a way that provides a specific function form

• A. tissues, which build organs.
• B. organs, which build tissues.
• C. organ systems, which build tissues.
• D. atoms, which comprise tissues.

Correct answer: A

Rationale: The correct answer is 'tissues, which build organs.' Specialized cell types organize to form tissues, which in turn build organs. Tissues are groups of cells that work together to perform a specific function. Option B is incorrect because organs are composed of tissues, not the other way around. Option C is incorrect as organ systems consist of multiple organs working together, not building tissues. Option D is incorrect as atoms are the basic building blocks of matter and are not directly involved in forming tissues.

2. Which of the following statements is true concerning the female reproductive system?

• A. It produces female sex cells.
• B. It transports the female sex cells.
• C. It can support the development of an embryo.
• D. All of the above

Correct answer: D

Rationale: The correct answer is 'All of the above.' The female reproductive system produces female sex cells (eggs), transports them through the fallopian tubes, and can support the development of an embryo through the uterus. Choice A is correct because the ovaries produce eggs, choice B is correct as the fallopian tubes transport the eggs, and choice C is correct as the uterus provides the environment for the embryo to develop. Therefore, all of these statements are true regarding the female reproductive system.

3. Blood cells are produced in the organs of the _______ system.

• A. endocrine
• B. skeletal
• C. superior to
• D. inferior to

Correct answer: C

Rationale: Blood cells are produced in the organs of the hematopoietic system. The correct answer is 'superior to' as this refers to the location of the organs responsible for blood cell production, typically bone marrow found in bones such as the vertebrae, ribs, and skull. 'Endocrine' (Choice A) refers to a different system responsible for hormone production. 'Skeletal' (Choice B) relates to bones but not specifically to the production of blood cells. Choices C and D, 'superior to' and 'inferior to,' do not make sense in the context of blood cell production and are incorrect.

4. Maintaining a stable internal environment typically requires

• A. positive feedback mechanisms.
• B. an unstable outside environment.
• C. decreased atmospheric pressure.
• D. negative feedback mechanisms.

Correct answer: D

Rationale: The correct answer is 'negative feedback mechanisms.' In biological systems, negative feedback mechanisms help maintain homeostasis by counteracting any deviations from the set point. They work to stabilize internal conditions and keep them within a narrow range. On the other hand, positive feedback mechanisms amplify changes and are not involved in maintaining stability. Choice B, 'an unstable outside environment,' is incorrect as internal stability is independent of external conditions like weather. Choice C, 'decreased atmospheric pressure,' is also incorrect as it does not directly relate to internal homeostasis.

5. Simple squamous epithelium is an example of a(n)

• A. organ system.
• B. organ.
• C. tissue.
• D. molecule.

Correct answer: C

Rationale: Simple squamous epithelium is a type of tissue, not an organ system, organ, or molecule. Tissues are groups of cells that work together to perform a specific function. In this case, simple squamous epithelium is a thin, single layer of flattened cells that line surfaces involved in passive diffusion, such as the alveoli in the lungs or blood vessels. Therefore, the correct answer is 'tissue.' Choices A, B, and D are incorrect as they do not accurately categorize simple squamous epithelium as a tissue.
