1. The measurable electrical activity of the brain is recorded by a:
- A. CAT scan
- B. MRI scan
- C. Electroencephalogram (EEG)
- D. X-ray
Correct answer: C
Rationale: The correct answer is C: "Electroencephalogram (EEG)". An EEG is a non-invasive test that measures the electrical activity of the brain by placing electrodes on the scalp. It is specifically designed to record brain wave patterns, making it a valuable tool in diagnosing conditions such as epilepsy, sleep disorders, and brain injuries. A CAT scan (A) and MRI scan (B) are imaging techniques that show the structure of the brain, while an X-ray (D) is not typically used to measure brain electrical activity.
2. Which property of a wave represents the distance between two successive identical points on a wave?
- A. Wavelength
- B. Amplitude
- C. Frequency
- D. Period
Correct answer: a
Rationale: Wavelength is the distance between two identical points (like crests or troughs) on a wave.
3. He discusses the goal of the department. Which of the following statements is a goal?
- A. Increase the patient satisfaction rate
- B. Eliminate the incidence of delayed administration of medications
- C. Establish rapport with patients.
- D. Reduce response time to two minutes.
Correct answer: A
Rationale: Option A, 'Increase the patient satisfaction rate,' is a goal because it represents an objective that the department aims to achieve. Patient satisfaction is a key indicator of quality care and reflects the department's commitment to providing excellent service. In contrast, options B, C, and D are more focused on specific actions or strategies rather than overarching goals. Eliminating delayed medication administration, establishing rapport with patients, and reducing response time are important tasks that may contribute to achieving the goal of increasing patient satisfaction, but they are not goals in themselves. Therefore, option A is the most appropriate choice as it directly addresses the department's ultimate objective of enhancing patient satisfaction.
4. The process of a liquid changing into a gas is called:
- A. Evaporation
- B. Boiling
- C. Condensation
- D. Sublimation
Correct answer: A
Rationale: Evaporation occurs at any temperature, while boiling only occurs at the boiling point of the liquid.
5. How is the density of a substance calculated?
- A. Mass / Volume
- B. Volume / Mass
- C. Mass x Volume
- D. None of the above
Correct answer: A
Rationale: Density is the mass per unit volume of a substance.
6. A spring is stretched and released, causing an object attached to it to oscillate. What determines the frequency of the oscillations?
- A. The mass of the object
- B. The stiffness of the spring
- C. The initial displacement of the object
- D. All of the above
Correct answer: B
Rationale: The stiffness of the spring. Frequency depends on the spring constant and the mass, but the mass term cancels out in the formula for simple harmonic motion, leaving only the spring constant.
