1. Among many Asians there is a belief in the yin\yang theory, rooted in the ancient Chinese philosophy of Tao. The nurse recognizes which statement that most accurately reflects "health" in an Asian with this belief?
- A. A person is able to work and produce.
- B. A person is happy, stable, and feels good.
- C. All aspects of the person are in perfect balance.
- D. A person is able to care for others and function socially. - C) All aspects of the person are in perfect balance. Page: 21 Many Asians believe in the yin\yang theory, in which health is believed to exist when all aspects of the person are in perfect balance. The other statements do not describe this theory.
Correct answer: C
Rationale: In Asian belief systems like the yin\yang theory rooted in Tao philosophy, health is seen as existing when all aspects of a person are in perfect balance. This means that physical, mental, emotional, and spiritual elements need to be harmonized for an individual to be considered healthy. The other statements do not encapsulate this holistic perspective on health.
2. Which one is not a reactant in photosynthesis?
- A. Water
- B. Light energy
- C. Glucose
- D. Carbon dioxide
Correct answer: C
Rationale: The correct answer is C: Glucose. Glucose is not a reactant in photosynthesis but a product. During photosynthesis, plants use water, carbon dioxide, and light energy as reactants to produce glucose and oxygen. Water is essential for the process of photosynthesis, along with carbon dioxide and light energy. Light energy is necessary for the light-dependent reactions to occur, which eventually leads to the production of glucose. Carbon dioxide is absorbed by plants through tiny pores called stomata and is used in the Calvin cycle to synthesize glucose. Therefore, glucose is the product of photosynthesis, not a reactant.
3. What is the first step in the conversion of glucose to pyruvate?
- A. Glycolysis
- B. Krebs cycle
- C. Electron transport chain
- D. Aerobic respiration
Correct answer: A
Rationale: The correct answer is Glycolysis. Glycolysis is the initial step in the conversion of glucose to pyruvate. During glycolysis, glucose is broken down into pyruvate through a series of enzymatic reactions. Choice B, the Krebs cycle, occurs after glycolysis in aerobic cellular respiration. Choice C, the Electron transport chain, is the final step in aerobic respiration where the majority of ATP is produced. Choice D, Aerobic respiration, is a broader term that encompasses glycolysis, the Krebs cycle, and the electron transport chain, but it is not the specific first step in the conversion of glucose to pyruvate.
4. If you are an assiduous worker, you are probably ____?
- A. Lazy
- B. Industrious
- C. Inconsistent
- D. Procrastinating
Correct answer: B
Rationale: The correct answer is B. If someone is described as assiduous, it means they are diligent, hardworking, and persistent in their efforts. This aligns with the trait of being 'Industrious.' Choices A, C, and D are incorrect because being lazy, inconsistent, or procrastinating are the opposite characteristics of someone who is assiduous.
5. A set of temperature readings has a range of 5 degrees Celsius. What does this tell you about the data?
- A. The average temperature is 5 degrees Celsius.
- B. All temperatures are within 5 degrees of each other.
- C. The difference between the highest and lowest temperatures is 5 degrees.
- D. There are exactly 5 temperatures in the set.
Correct answer: C
Rationale: Option A is incorrect because the range of 5 degrees does not necessarily mean that the average temperature is 5 degrees Celsius. The average temperature could be any value within the range. Option B is incorrect because the range of 5 degrees does not mean that all temperatures are within 5 degrees of each other. It only indicates the difference between the highest and lowest temperatures. Option C is correct because the range of 5 degrees specifically refers to the difference between the highest and lowest temperatures in the set. This is a common definition of range in statistics. Option D is incorrect because the range of 5 degrees does not determine the number of temperatures in the set. The set could have more or fewer than 5 temperatures.
