Nursing Elites

1. He raised the issue on giving priority to patient needs. Which of the following offers the best

• A. Assessing nursing needs and problems
• B. Giving instructions on how nursing care needs are to be met
• C. Controlling and evaluating the delivery of nursing care
• D. Assigning safe nurse: patient ratio

Correct answer: A

Rationale: In the context of the sentence 'He raised the issue on giving priority to patient needs,' the best option is 'Assessing nursing needs and problems' (Option A). This option directly aligns with the idea of prioritizing patient needs by first understanding and assessing the specific nursing needs and problems. By assessing these needs, healthcare providers can tailor their care to address the most pressing concerns of the patients, thus effectively giving priority to patient needs. The other options, such as giving instructions on how nursing care needs are to be met (Option B), controlling and evaluating the delivery of nursing care (Option C), and assigning safe nurse: patient ratio (Option D), do not directly address the importance of assessing patient needs as a crucial step in prioritizing patient care. Therefore, Option A is the most suitable choice in this scenario.

2. Epithelial tissue, which covers surfaces, is further classified based on the number of cell layers. Simple epithelium has:

• A. No layers
• B. One layer
• C. Two to several layers
• D. Many tightly packed layers

Correct answer: B

Rationale: The correct answer is B: 'One layer.' Simple epithelium is characterized by having a single layer of cells. This type of epithelial tissue is found in areas where diffusion, filtration, or absorption are primary functions. Simple epithelium allows for efficient exchange of substances across the cell layer due to its thin structure and close proximity to underlying tissues. Examples of locations where simple epithelium is found include the lining of blood vessels (endothelium) and air sacs of the lungs (alveoli). In contrast, stratified epithelium consists of multiple layers of cells and is commonly found in areas that require protection against mechanical or chemical stress, such as the skin and the lining of the esophagus.

3. Edema is a condition characterized by swelling caused by a buildup of lymph fluid. What factors can contribute to edema?

• A. Regular exercise
• B. Maintaining a healthy weight
• C. Poor circulation or blockage in the lymphatic system
• D. Proper hydration

Correct answer: C

Rationale: Edema is a condition where there is an abnormal accumulation of fluid in the body tissues, leading to swelling. Poor circulation or blockage in the lymphatic system can contribute to edema by hindering the proper drainage of lymph fluid. When the lymphatic system is not functioning efficiently, it can result in fluid retention and swelling in the affected areas. Regular exercise and maintaining a healthy weight can actually help improve circulation and lymphatic flow, reducing the risk of edema. Proper hydration is important for overall health but specifically does not directly contribute to the development of edema as poor circulation or lymphatic blockages do.

4. The deeper layer of the skin, containing connective tissue, blood vessels, and nerve endings, is called the:

• A. Epidermis
• B. Dermis
• C. Hypodermis
• D. Stratum corneum

Correct answer: B

Rationale: The correct answer is B: Dermis. The dermis is the deeper layer of the skin that contains important structures such as connective tissue, blood vessels, and nerve endings. It plays a crucial role in providing support and nourishment to the epidermis, the outermost layer of the skin. The epidermis, option A, is actually the outermost layer responsible for protecting the body from environmental factors. The hypodermis, option C, is the deepest layer of the skin that primarily consists of fat and connective tissue. Stratum corneum, option D, is the outermost layer of the epidermis composed of dead skin cells. Therefore, the dermis is the correct answer in this case.

5. Which additional information would be MOST helpful in further understanding the issue of microplastics?

• A. The economic costs associated with plastic pollution cleanup.
• B. The specific types of microbes used in bioremediation processes.
• C. The historical timeline of plastic production and its global distribution.
• D. The aesthetic impact of plastic pollution on beaches and tourism.

Correct answer: B

Rationale: Understanding the specific microbes used in bioremediation would directly contribute to knowledge about the solution proposed in the passage.

6. What is the process by which a cell divides into two or more new cells?

• A. Mitosis
• B. Meiosis
• C. Both mitosis and meiosis
• D. None of the above

Correct answer: A

Rationale: Rationale: Mitosis is the process by which a cell divides into two identical daughter cells. This type of cell division is essential for growth, repair, and maintenance of multicellular organisms. Meiosis, on the other hand, is a type of cell division that produces gametes (sperm and egg cells) with half the number of chromosomes as the parent cell. Therefore, meiosis is not the process by which a cell divides into two or more new cells. Option C is incorrect because meiosis is not involved in the general process of cell division to produce new cells. Option D is incorrect because mitosis is the correct process for cell division.
