Nursing Leadership and Management
1. Which of the following guidelines should be least considered in formulating objectives for
- A. Written nursing care plan
- B. Holistic approach
- C. Prescribed standards
- D. Staff preferences
Correct answer: D
Rationale: When formulating objectives for a written nursing care plan, staff preferences should be least considered. Objectives should be based on patient needs, evidence-based practice, and professional standards rather than personal preferences of the staff. Prescribed standards ensure quality care and adherence to best practices. A holistic approach considers the whole patient, including physical, emotional, and spiritual aspects. Staff preferences may introduce bias and should not dictate patient care objectives.
2. What is the scientific term for scar tissue?
- A. Epithelial tissue
- B. Fibrous connective tissue
- C. Cartilage
- D. Adipose tissue
Correct answer: B
Rationale: The correct answer is B: Fibrous connective tissue. Scar tissue is formed during the process of wound healing, where fibroblasts produce collagen fibers to repair damaged tissue. This results in the formation of fibrous connective tissue, which is different from epithelial tissue (A), cartilage (C), and adipose tissue (D). While epithelial tissue lines surfaces and organs, cartilage is a type of connective tissue found in joints, and adipose tissue is a type of connective tissue that stores energy in the form of fat. Scar tissue, on the other hand, is primarily composed of collagen fibers and is classified as fibrous connective tissue.
3. Which of the following is the main function of the kidneys?
- A. To filter waste products from the blood
- B. To produce urine
- C. To regulate blood pressure
- D. To produce hormones that help to control blood sugar levels
Correct answer: A
Rationale: Rationale: A) To filter waste products from the blood: The main function of the kidneys is to filter waste products, excess ions, and water from the bloodstream to form urine, which is then excreted from the body. This process helps maintain the body's internal environment by regulating the balance of electrolytes, fluid volume, and pH levels. B) To produce urine: While the kidneys do produce urine as a result of filtering the blood, the primary function is to filter waste products rather than solely producing urine. C) To regulate blood pressure: The kidneys do play a role in regulating blood pressure by controlling the volume of blood and the concentration of electrolytes in the body, but their main function is waste filtration. D) To produce hormones that help to control blood sugar levels: While the kidneys do produce hormones like erythropoietin and renin that play a role in various physiological processes, such as red
4. The fossil record shows that dinosaurs with feathers existed millions of years before birds. This is evidence for
- A. Convergent evolution (unrelated organisms evolving similar traits)
- B. Divergent evolution (related organisms evolving different traits)
- C. Coevolution (two species influencing each other's evolution)
- D. The extinction of dinosaurs due to an asteroid impact
Correct answer: A
Rationale: Rationale: The fossil record indicating that dinosaurs had feathers before birds suggests convergent evolution. Convergent evolution occurs when unrelated organisms independently evolve similar traits to adapt to similar environmental pressures. In this case, both dinosaurs and birds developed feathers for flight or insulation purposes, even though they are not closely related. This evidence supports the concept of convergent evolution rather than divergent evolution, coevolution, or the extinction of dinosaurs due to an asteroid impact.
5. In a single displacement reaction, one element takes the place of another element in a compound. Which of the following is an example?
- A. 2H2 + O2 -> 2H2O
- B. Zn + 2HCl -> ZnCl2 + H2
- C. CaCO3 -> CaO + CO2
- D. CH4 + 2O2 -> CO2 + 2H2O
Correct answer: B
Rationale: In a single displacement reaction, one element replaces another element in a compound. Option B, 'Zn + 2HCl -> ZnCl2 + H2,' is an example of a single displacement reaction where zinc (Zn) replaces hydrogen (H) in hydrochloric acid (HCl) to form zinc chloride (ZnCl2) and hydrogen gas (H2). The other options do not involve one element displacing another in a compound. Option A is a synthesis reaction, option C is a decomposition reaction, and option D is a combustion reaction. Therefore, option B is the correct answer as it demonstrates the concept of single displacement reactions.
6. Which term describes the ability of a substance to conduct electricity?
- A. Reactivity
- B. Density
- C. Conductivity
- D. Viscosity
Correct answer: c
Rationale: Conductivity refers to a substance's ability to conduct electricity. Substances that conduct electricity well are known as conductors.
