1. How many liters are there in 2,500 milliliters?

• A. 2.5 liters
• B. 25 liters
• C. 250 liters
• D. 25,000 liters

Correct answer: A

Rationale: There are 1,000 milliliters in a liter. To convert 2,500 milliliters to liters, you divide by 1,000: 2,500 milliliters / 1,000 = 2.5 liters. Therefore, choice A, '2.5 liters,' is the correct answer. Choice B, '25 liters,' is incorrect as it would be the result if you mistakenly multiplied instead of dividing. Choice C, '250 liters,' is incorrect as it is 100 times the correct answer. Choice D, '25,000 liters,' is significantly higher and not a conversion error but an order of magnitude error.

2. In a U-tube manometer, a fluid is used to measure pressure differences. When one side is connected to a pressurized system, the fluid level on that side will:

• A. Remain the same
• B. Decrease
• C. Increase
• D. Depend on the type of fluid used

Correct answer: B

Rationale: In a U-tube manometer, the side connected to a pressurized system will experience a decrease in fluid level due to the pressure exerted by the system. This pressure forces the fluid down, causing the fluid level to decrease. Therefore, choice B is correct. Choices A and C are incorrect because the fluid level will not remain the same or increase when connected to a pressurized system. Choice D is incorrect as the type of fluid used does not determine the direction of the fluid movement in response to pressure.

3. What is the best description for the word 'distal'?

• A. Receives blood from lungs
• B. Farthest from injury
• C. Closest to heart
• D. Empathetic

Correct answer: B

Rationale: The correct answer is B: 'Farthest from injury.' In medical terminology, 'distal' refers to the body part that is farthest from the point of reference or injury. The term is commonly used to describe the location of structures in relation to a point of origin or attachment. Choices A, C, and D are incorrect because 'distal' specifically denotes a spatial relationship in terms of distance from a point of reference, not blood flow, proximity to the heart, or emotional empathy.

4. What takes place in a lysosome?

• A. Ribosomes are made.
• B. Food is produced.
• C. Water is stored.
• D. Food is digested.

Correct answer: D

Rationale: In a lysosome, food particles are digested through the action of enzymes. Lysosomes are membrane-bound organelles containing digestive enzymes that break down large molecules into smaller ones, allowing the cell to utilize the nutrients for energy and other processes. Choices A, B, and C are incorrect because ribosomes are not made in lysosomes, food is not produced in lysosomes, and lysosomes do not store water.

5. The word watchdog as used in the second paragraph of the passage can best be defined as ___________.

• A. companion
• B. guard
• C. manager
• D. punisher

Correct answer: B

Rationale: In this context, "watchdog" refers to a guard or overseer, specifically relating to Lifewings Partners’ mission of ensuring safety and preventing medical errors. The organization acts as a monitor in healthcare settings, which aligns with the definition of a watchdog, confirming that option B is correct.
