1. Which of the following is NOT a risk factor for developing atherosclerosis?
- A. High blood pressure
- B. High levels of LDL cholesterol
- C. Regular physical activity
- D. Smoking
Correct answer: C
Rationale: Regular physical activity is NOT a risk factor for developing atherosclerosis. In fact, engaging in regular physical activity can help reduce the risk of developing atherosclerosis by improving cardiovascular health, lowering blood pressure, and reducing LDL cholesterol levels. High blood pressure, high levels of LDL cholesterol, and smoking are all known risk factors for atherosclerosis. High blood pressure can damage blood vessels, making them more susceptible to plaque buildup. High levels of LDL cholesterol can lead to the accumulation of plaque in the arteries, narrowing the passageways and increasing the risk of atherosclerosis. Smoking is harmful to blood vessels, promoting inflammation and the formation of plaque. Therefore, regular physical activity is actually a protective factor against atherosclerosis rather than a risk factor.
2. What is the unit of measurement for power?
- A. Joule (J)
- B. Newton (N)
- C. Watt (W)
- D. Kilogram-meter (kg·m)
Correct answer: c
Rationale: Power is measured in watts (W) in the SI unit system.
3. Which of the following factors would increase the solubility of a gas in a liquid?
- A. Decreasing temperature
- B. Increasing pressure
- C. Decreasing surface area
- D. Increasing particle size
Correct answer: b
Rationale: Henry's law states that the solubility of a gas in a liquid is directly proportional to the pressure of the gas above the liquid. The other choices would typically decrease solubility.
4. In a chemical reaction, the total amount of:
- A. Matter remains the same
- B. Matter increases
- C. Matter decreases
- D. Energy remains the same
Correct answer: A
Rationale: The Law of Conservation of Mass states that matter cannot be created or destroyed in a chemical reaction, only rearranged
5. How does an unbalanced force affect an object at rest?
- A. It maintains the object's state of rest
- B. It does not affect the object's rest
- C. It moves the object into motion
- D. It decreases the object's mass
Correct answer: c
Rationale: An unbalanced force acting on an object at rest causes it to start moving.
6. Functional nursing has some advantages, which one is an EXCEPTION?
- A. Psychological and sociological needs are emphasized.
- B. Great control of work activities.
- C. Most economical way of delivering nursing services.
- D. Workers feel secure in dependent role
Correct answer: B
Rationale: Functional nursing is a task-oriented approach where each nurse is assigned specific duties, leading to efficient task completion but often resulting in a lack of holistic care. While functional nursing may provide great control over work activities and can be cost-effective due to specialization, it does not emphasize psychological and sociological needs, which is a significant disadvantage. Additionally, the dependent role that workers feel in functional nursing can lead to disempowerment and hinder professional growth and autonomy. Therefore, option A, 'Psychological and sociological needs are emphasized,' is the exception among the advantages of functional nursing.
