Reading
1. What is the author's stance towards the idea of smart cities?
- A. Strongly supportive, emphasizing only the benefits.
- B. Strongly critical, focusing solely on the drawbacks.
- C. Balanced and objective, highlighting both potential and concerns.
- D. Indecisive and unclear about the overall value of smart cities.
Correct answer: C
Rationale: The passage acknowledges both the promise and challenges of smart cities, demonstrating a balanced perspective.
2. In the reaction 2H2 + O2 → 2H2O, how many moles of oxygen are required to react completely with 4 moles of hydrogen?
- A. 1
- B. 2
- C. 3
- D. 4
Correct answer: 2
Rationale: The balanced equation indicates a 1:1 ratio between H2 and O2, so 4 moles of H2 require 4 moles of O2, and 2 moles of H2 require 2 moles of O2.
3. Kidney stones are formed when:
- A. Excess water is not reabsorbed
- B. Minerals crystallize in the urine
- C. Electrolytes become too concentrated
- D. All of the above
Correct answer: B
Rationale: The correct answer is B: "Minerals crystallize in the urine." Kidney stones are formed when minerals in the urine combine and crystallize, forming solid masses. This process can occur due to various factors, such as high levels of calcium, oxalate, or uric acid in the urine. Options A and C are not directly related to the formation of kidney stones. Option D is incorrect because not all the statements are true; only minerals crystallizing in the urine lead to kidney stone formation.
4. A medication order is written as 3/4 of a tablet. If each tablet is 500mg, what is the equivalent dosage in milligrams?
- A. 375mg
- B. 425mg
- C. 450mg
- D. 475mg
Correct answer: A
Rationale: Multiply the tablet strength (500mg) by the fractional dose (3/4) to get 375 milligrams.
5. Which neurotransmitter is associated with mood, sleep, and memory?
- A. Dopamine
- B. Serotonin
- C. Acetylcholine
- D. Glutamate
Correct answer: B
Rationale: The correct answer is B: Serotonin. Serotonin is a neurotransmitter that plays a crucial role in regulating mood, sleep, and memory. It is known as the 'feel-good' neurotransmitter because it helps to promote feelings of well-being and happiness. Serotonin also contributes to the regulation of sleep patterns and plays a role in memory and learning processes. Dopamine is associated with reward and motivation, acetylcholine with muscle movement and cognitive functions, and glutamate with learning and memory as an excitatory neurotransmitter. Therefore, of the options provided, serotonin is the neurotransmitter most closely linked to mood, sleep, and memory.
6. Stephanie delegates effectively if she has authority to act, which is BEST defined as:
- A. having responsibility to direct others
- B. being accountable to the organization
- C. having legitimate right to act
- D. telling others what to do
Correct answer: A
Rationale: The correct answer is A: 'having responsibility to direct others.' Effective delegation involves entrusting tasks and responsibilities to others while still maintaining ultimate accountability. Authority to act means having the responsibility to direct others, making decisions, and overseeing the completion of tasks. This definition aligns with the core concept of delegation, where individuals are empowered and authorized to carry out specific duties. Being accountable to the organization (option B) is important but does not fully capture the proactive nature of delegation. Having a legitimate right to act (option C) is essential for effective delegation, but it is more about the formal authorization rather than the active responsibility to direct others. Simply telling others what to do (option D) is a narrow and authoritarian view of delegation that does not encompass the collaborative and empowering nature of effective delegation.
