1. What does the prefix 'milli' mean?

• A. 0.01
• B. 0.001
• C. 0.0001
• D. 0.00001

Correct answer: B

Rationale: The prefix 'milli' means one-thousandth, which is equivalent to 0.001 of the base unit. For instance, 1 millimeter is equal to 0.001 meters. Choice A (0.01) is incorrect as it represents one-hundredth, not one-thousandth. Choice C (0.0001) is incorrect as it signifies ten-thousandth, not one-thousandth. Choice D (0.00001) is incorrect as it stands for one-hundred-thousandth, not one-thousandth.

2. Convert 5 kilograms to grams.

• A. 50 grams
• B. 500 grams
• C. 5,000 grams
• D. 50,000 grams

Correct answer: C

Rationale: To convert kilograms to grams, you need to multiply by 1000 since there are 1000 grams in a kilogram. Therefore, 5 kilograms is equal to 5,000 grams. Choices A, B, and D are incorrect because they do not correctly convert the given amount of kilograms to grams.

3. What is the equivalent of 0.3 mg in mcg?

• A. 300 mcg
• B. 30 mcg
• C. 3000 mcg
• D. 3 mcg

Correct answer: A

Rationale: To convert milligrams (mg) to micrograms (mcg), you need to multiply by 1000 since 1 mg is equal to 1000 mcg. Therefore, 0.3 mg x 1000 = 300 mcg. This conversion is crucial in healthcare to ensure accurate medication dosages. Choice B (30 mcg) is incorrect as it represents the conversion of 0.03 mg to mcg. Choice C (3000 mcg) is incorrect as it is the result of multiplying 0.3 mg by 10 instead of 1000. Choice D (3 mcg) is incorrect as it is the result of not multiplying by 1000 to convert milligrams to micrograms.

4. What is the result of multiplying 0.15 by 3?

• A. 0.05
• B. 0.15
• C. 0.45
• D. 0.45

Correct answer: C

Rationale: The correct answer is C: 0.45. To find the result of multiplying 0.15 by 3, you simply multiply the two numbers together, which gives you 0.45. Choice A (0.05) is incorrect as it is the result of dividing 0.15 by 3 instead of multiplying. Choice B (0.15) is the original number being multiplied and not the result. Choice D (0.45) is the same as the correct answer but is repeated for redundancy.

5. How many feet are in one mile?

• A. 5000 feet
• B. 5280 feet
• C. 5300 feet
• D. 5500 feet

Correct answer: B

Rationale: The correct answer is B: 5280 feet. One mile is equivalent to 5280 feet. This is a standard conversion that is widely known. Choice A (5000 feet) is incorrect as it is not the exact conversion of a mile. Choice C (5300 feet) and choice D (5500 feet) are also incorrect as they do not represent the accurate conversion from miles to feet.
