1. What is 0.075 mg in mcg?

• A. 0.075 mcg
• B. 7.5 mcg
• C. 0.75 mcg
• D. 750 mcg

Correct answer: D

Rationale: To convert milligrams to micrograms, you need to multiply by 1000 since 1 mg = 1000 mcg. Therefore, 0.075 mg equals 75 * 1000 = 750 mcg. The correct answer is 750 mcg. Choices A, B, and C are incorrect because they do not apply the correct conversion factor of 1000. It is essential to understand these conversions, especially in medical settings where accurate dosing is crucial to avoid errors and ensure patient safety.

2. Convert 345 centimeters to kilometers (km).

• A. 0.00345 km
• B. 0.0345 km
• C. 0.345 km
• D. 34.5 km

Correct answer: B

Rationale: To convert centimeters to kilometers, you need to divide by 100,000 since there are 100,000 centimeters in a kilometer. Therefore, 345 cm ÷ 100,000 = 0.00345 km. The correct answer is 0.0345 km, which is obtained by accurately dividing 345 by 100,000. Choices A, C, and D are incorrect because they do not correctly apply the conversion factor and result in inaccurate values for kilometers.

3. What is the metric prefix for 10^-12 and how does it relate to meters?

• A. pico- (p) = 10^-12 meters
• B. nano- (n) = 10^-12 meters
• C. femto- (f) = 10^-12 meters
• D. pico- (p) = 10^-15 meters

Correct answer: C

Rationale: The prefix 'femto-' stands for 10^-15, making femtometer equal to 10^-15 meters. The incorrect choices are A and B because 'pico-' represents 10^-12 (picometer) and 'nano-' represents 10^-9 (nanometer), respectively. Choice D is also incorrect as 'pico-' is associated with 10^-12, not 10^-15.

4. 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.

5. How many quarts are in 1 gallon?

• A. 2 quarts
• B. 4 quarts
• C. 3 quarts
• D. 1 quart

Correct answer: B

Rationale: The correct answer is B: 4 quarts. There are 4 quarts in 1 gallon. This conversion is based on the fact that 1 gallon is equivalent to 4 quarts. Choice A is incorrect as 2 quarts are half of a gallon, not a whole gallon. Choice C is incorrect as 3 quarts is less than a gallon. Choice D is incorrect as it represents only one quart, whereas the question asks for the quantity in a gallon.
