Physics

1. A ball is thrown upwards. Which of the following statements is TRUE about its potential energy and kinetic energy at the peak of its trajectory?

Correct answer: B

Rationale: At the peak, the ball momentarily stops moving, minimizing kinetic energy. However, it's still at its highest point, maximizing its potential energy due to gravity.

2. A medication order is for 250 micrograms of a drug to be administered subcutaneously. The available syringe measures in milliliters. How many milliliters should the nurse draw up?

Correct answer: B

Rationale: First convert micrograms to milliliters, knowing 1000 micrograms equal 1 milliliter. Divide the desired dosage (250 micrograms) by the conversion factor (1000 micrograms/milliliter) to find the volume needed: 250 micrograms / 1000 micrograms/milliliter = 0.00025 milliliters. However, drawing such a small volume might be inaccurate, so round to the nearest practical measurement, which is 0.0025 milliliters.

3. Which of the following is NOT a greenhouse gas?

Correct answer: C

Rationale: Rationale: A) Carbon Dioxide: Carbon dioxide is a greenhouse gas that is released into the atmosphere through various human activities such as burning fossil fuels and deforestation. B) Methane: Methane is another greenhouse gas that is released from sources like livestock, landfills, and natural gas production. C) Oxygen: Oxygen is not considered a greenhouse gas. It is a vital component of the Earth's atmosphere that is necessary for respiration and combustion. D) Water Vapor: Water vapor is also a greenhouse gas that plays a significant role in the Earth's climate system by trapping heat in the atmosphere. Therefore, the correct answer is C) Oxygen, as it is not a greenhouse gas.

4. Acknowledge the organ devoted to blood filtration.

Correct answer: B

Rationale: The kidneys are the primary organs responsible for filtering blood and removing waste products, excess fluids, and toxins. They play a crucial role in maintaining the body's internal environment and regulating blood pressure.

5. What type of energy is possessed by an object due to its position or configuration?

Correct answer: c

Rationale: Potential energy is the energy possessed by an object due to its position or state.

6. A medication must be taken twice daily, 12 hours apart. If the first dose is at 8:00 AM, what is the most convenient time for the second dose to avoid disrupting sleep?

Correct answer: B

Rationale: Rationale: To take the medication 12 hours apart from the first dose at 8:00 AM, the second dose should be taken at 8:00 PM. However, to avoid disrupting sleep, it is recommended to take the second dose a bit earlier. Taking the second dose at 6:00 PM ensures that the medication is still being taken 12 hours apart while allowing for a buffer before bedtime to avoid any potential disruptions to sleep.
