Mathematics

1. A pressure vessel has a cylindrical body (diameter 10cm, height 20cm) with hemispherical ends (same diameter as the cylinder). What is its total surface area?

Correct answer: D

Rationale: Calculate the surface area of the cylinder (base + lateral surface) and two hemispheres. Add them all up for the total surface area.

2. Which sentence uses the past perfect tense correctly?

Correct answer: A

Rationale: Option A expresses an action ("party began") completed before another past action ("I arrived").

3. Electroencephalography (EEG) measures electrical activity in the brain, primarily reflecting the activity of:

Correct answer: A

Rationale: The correct answer is A: Neurons. Electroencephalography (EEG) measures the electrical activity in the brain, which is primarily generated by the neurons. Neurons are the main cells responsible for transmitting electrical signals in the brain, making them the key source of the brain's electrical activity. Astrocytes, oligodendrocytes, and microglia are important supporting cells in the brain but do not generate the electrical impulses that EEG measures. Therefore, the correct choice is A: Neurons.

4. Which of the following is TRUE about functional nursing?

Correct answer: B

Rationale: The correct answer is B: "Emphasizes use of group collaboration." Functional nursing is a task-oriented approach where team members specialize in specific tasks or activities. In this model, nurses work together in groups to provide care to a larger number of patients efficiently. This differs from the one-to-one nurse-patient ratio (C) and the continuous, coordinated, and comprehensive nursing services (D). While functional nursing concentrates on tasks (A), the key feature emphasized in this care delivery model is the use of group collaboration to provide care effectively.

5. Antidiuretic hormone (ADH) plays a crucial role in regulating water balance. When ADH levels are high, what happens to urine production?

Correct answer: B

Rationale: When antidiuretic hormone (ADH) levels are high, it indicates that the body needs to conserve water. ADH works by increasing the permeability of the collecting ducts in the kidneys, allowing more water to be reabsorbed back into the bloodstream. This action leads to a decrease in urine production, as the body retains more water to maintain proper fluid balance. Therefore, the correct answer is B: 'Urine production decreases to conserve water.' High levels of ADH help the body prevent dehydration by reducing the amount of water lost in urine.

6. What is the part of the nervous system responsible for the “fight-or-flight” response?

Correct answer: C

Rationale: The correct answer is C: Sympathetic nervous system. The sympathetic nervous system is responsible for the "fight-or-flight" response, which is the body's automatic response to perceived threat or danger. When activated, this system increases heart rate, dilates airways, and redirects blood flow to muscles to prepare the body for action. The somatic nervous system (A) controls voluntary movements, the parasympathetic nervous system (B) is responsible for the "rest and digest" response, and the enteric nervous system (D) regulates the digestive system. Therefore, the sympathetic nervous system is the specific part of the nervous system involved in the fight-or-flight response.
