Nursing Elites

ATI TEAS 7

Anatomy

1. The outermost layer of your skin is an example of which epithelial tissue type?

Correct answer: B

Rationale: The correct answer is B: Stratified squamous. The outermost layer of the skin, known as the epidermis, is primarily composed of stratified squamous epithelium. This type of epithelial tissue is designed to protect underlying tissues from abrasion and external factors. Simple cuboidal epithelium (option A) is typically found in areas where secretion and absorption occur, like in kidney tubules. Simple columnar epithelium (option C) lines the intestines and aids in absorption. Stratified columnar epithelium (option D) is relatively rare in the body and is found in limited areas such as parts of the male urethra. Hence, option B is the best choice as it accurately reflects the specific type of epithelial tissue that forms the outer layer of the skin.

2. One staff suggests that they review the pattern of nursing care that they are using, which is

Correct answer: B

Rationale: The correct answer is B: 'system used to deliver care.' When a staff member suggests reviewing the pattern of nursing care being used, they are referring to the overall system or method in place for delivering care to patients. This includes the processes, protocols, and techniques used to provide nursing care. It goes beyond just following a job description, manual of procedure, or rules. By evaluating and potentially revising the system used to deliver care, staff can ensure that best practices are in place to provide high-quality and effective care to patients.

3. The energy released in nuclear fusion originates from:

Correct answer: B

Rationale: The correct answer is B: 'The binding energy released during the fusion of light nuclei.' Nuclear fusion is the process where light nuclei combine to form a heavier nucleus, releasing energy in the form of binding energy. This energy comes from the conversion of mass into energy as per Einstein's famous equation E=mc^2. In contrast, option A refers to nuclear fission, where heavy nuclei split into lighter nuclei, releasing energy. Option C is related to atomic energy levels, and option D involves the complete conversion of matter into energy, not specific to nuclear fusion. Therefore, the energy released in nuclear fusion originates from the binding energy released during the fusion of light nuclei.

4. What does "monophyletic" mean in the context of classification?

Correct answer: D

Rationale: Rationale: In the context of classification, "monophyletic" refers to a group that includes a common ancestor and all of its descendants. This group shares a single evolutionary origin and forms a complete branch on a phylogenetic tree. Monophyletic groups are considered natural and valid taxonomic units because they reflect evolutionary relationships accurately. Option D is the correct choice as it accurately defines the term "monophyletic" in the context of classification.

5. What property of a substance remains constant regardless of its location in the universe?

Correct answer: a

Rationale: Mass is an intrinsic property of matter that remains constant regardless of its location in the universe.

6. Hematopoietic tissue is responsible for

Correct answer: C

Rationale: Hematopoietic tissue is responsible for the production of blood cells. This specialized tissue is found in the bone marrow and is crucial for the continuous generation of red blood cells, white blood cells, and platelets. These blood cells play essential roles in oxygen transport, immune defense, and blood clotting. Building and repairing bone (option A) is primarily the function of osteoblasts and osteoclasts in bone tissue. Supporting and connecting tissues (option B) is the role of connective tissues like tendons and ligaments. Contracting for movement (option D) is the function of muscle tissue. Therefore, the correct answer is C, as hematopoietic tissue specifically focuses on blood cell production.
