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. Based on the principles of asepsis, the nurse should consider a sterile packet below waist level to be _____.
- A. contaminated
- B. sterilized
- C. clean
- D. untouched
Correct answer: A
Rationale: In aseptic techniques, maintaining the sterility of items is crucial. Placing a sterile packet below waist level exposes it to potential contamination from non-sterile surfaces or objects. Therefore, the correct term to describe the sterile packet in this situation is 'contaminated.' 'Sterilized' (choice B) is incorrect as it implies the packet has undergone a sterilization process, which may not be the case if it is now considered contaminated. 'Clean' (choice C) is incorrect because although the packet was initially sterile, placing it below waist level compromises its cleanliness. 'Untouched' (choice D) is incorrect as the packet has been touched or exposed to non-sterile areas, leading to potential contamination.
3. What is the primary role of hemoglobin in red blood cells?
- A. Carrying oxygen
- B. Carrying nutrients
- C. Carrying carbon dioxide
- D. Carrying waste products
Correct answer: A
Rationale: The correct answer is A: Carrying oxygen. Hemoglobin's primary function in red blood cells is to bind with oxygen in the lungs and transport it to the body's tissues and cells. This process is crucial for cellular respiration and the overall oxygenation of the body. Choices B, C, and D are incorrect because hemoglobin primarily carries oxygen, not nutrients, carbon dioxide, or waste products.
4. What charge do Group VIIA elements have?
- A. -1
- B. -2
- C. 0
- D. 1
Correct answer: A
Rationale: Group VIIA elements, also known as halogens, have a tendency to gain one electron to achieve a stable electron configuration, resulting in a -1 charge. This is because they have seven valence electrons and need one more to complete their octet, making them highly reactive in forming -1 ions. Therefore, the correct answer is A. Choice B (-2) is incorrect because Group VIIA elements typically gain one electron, not two. Choice C (0) is incorrect as these elements tend to form -1 ions by gaining one electron. Choice D (1) is incorrect because Group VIIA elements gain electrons to form negative ions, not positive ones.
5. A 3-volt flashlight uses a bulb with 60-ohm resistance. What current flows through the flashlight?
- A. o.05 amp
- B. o.5 amp
- C. 1.8 amp
- D. 18 amp
Correct answer: A
Rationale: : Using Ohm's Law, I = V / R: I = 3 / 60 = 0.05 amp. So, the correct current is 0.05 amp.
