1. Which of the following is the main organ responsible for producing bile?
- A. Liver
- B. Gallbladder
- C. Pancreas
- D. Stomach
Correct answer: A
Rationale: Rationale: The liver is the main organ responsible for producing bile. Bile is a greenish-yellow fluid that is produced by the liver and stored in the gallbladder. It plays a crucial role in the digestion and absorption of fats in the small intestine. The gallbladder releases bile into the small intestine when needed to aid in the digestion of fats. The pancreas is responsible for producing digestive enzymes and insulin, not bile. The stomach is primarily involved in the digestion of food through the secretion of gastric juices.
2. How is work defined in terms of force and displacement?
- A. Work is the product of force and displacement in any direction
- B. Work is done only when the displacement is vertical
- C. Work is done only when the force and displacement are perpendicular
- D. Work is the product of force and displacement in the direction of the force
Correct answer: d
Rationale: Work is calculated as the force applied to an object multiplied by the displacement of the object in the direction of the force.
3. Two coherent light waves with a slight phase difference interfere. What determines the resulting intensity of the combined wave?
- A. The individual intensities of the waves
- B. The wavelength of the waves
- C. The distance between the waves
- D. The color of the waves
Correct answer: A
Rationale: The intensity of the resulting wave depends on the individual intensities and the phase difference between the interfering waves. Constructive interference leads to higher intensity, while destructive interference leads to lower intensity.
4. 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.
5. Which of the following terms refers to the degeneration of nerve tissue?
- A. Potentiation
- B. Demyelination
- C. Reuptake
- D. Neurogenesis
Correct answer: B
Rationale: The correct answer is B: 'Demyelination.' Demyelination is the term used to describe the degeneration of the myelin sheath, the protective covering of nerve fibers. This process can lead to impaired nerve signal transmission and potential nerve damage. 'Potentiation' refers to the strengthening of neural connections, 'Reuptake' is the reabsorption of neurotransmitters by the presynaptic neuron, and 'Neurogenesis' is the generation of new nerve cells. In this context, demyelination is the most appropriate term related to nerve tissue degeneration.
6. Diabetic nephropathy, a complication of diabetes, affects the:
- A. Ureters
- B. Bladder
- C. Urethra
- D. Nephrons
Correct answer: D
Rationale: The correct answer is D: Nephrons. Diabetic nephropathy is a type of kidney disease that occurs as a complication of diabetes. It specifically affects the nephrons, which are the functional units of the kidneys responsible for filtering waste and excess fluids from the blood to produce urine. Damage to the nephrons can lead to kidney failure and other serious complications in individuals with diabetes. Therefore, understanding the impact of diabetes on the nephrons is crucial for managing diabetic nephropathy effectively.
