1. What mnemonic helps in recalling metric conversions?

• A. King Hector Died By Drinking Chocolate Milk
• B. Kittens Have Delighted By Dancing Cool Moves
• C. Memorize Your Units Well
• D. Convert These Every Time

Correct answer: A

Rationale: The mnemonic 'King Hector Died By Drinking Chocolate Milk' aids in recalling metric prefixes in order: kilo-, hecto-, deca-, base (meter, liter, gram), deci-, centi-, milli-. Choice B does not provide a relevant mnemonic for metric conversions. Choices C and D do not offer a helpful phrase for remembering metric prefixes, making them incorrect.

2. How many quarts are equivalent to 2 liters?

• A. 1.06 quarts
• B. 0.5 quarts
• C. 2.1 quarts
• D. 4 quarts

Correct answer: A

Rationale: To convert liters to quarts, we know that 1 liter is approximately equal to 1.06 quarts. Therefore, 2 liters would be around 2.12 quarts. However, for practical purposes, it's often rounded to 2.1 quarts. Option A, '1.06 quarts,' is the closest and most accurate approximation. Option B, '0.5 quarts,' is incorrect as it represents half of the actual conversion. Option C, '2.1 quarts,' is close but slightly higher than the actual conversion. Option D, '4 quarts,' is double the correct conversion and is therefore incorrect.

3. What is equivalent to 1 L?

• A. 1 kilogram
• B. 1 quart
• C. 1 milliliter
• D. 1000 milliliters

Correct answer: D

Rationale: 1 liter is equivalent to 1000 milliliters. This conversion is based on the fact that 1 liter equals 1000 milliliters, a standard metric relationship. Choice A is incorrect because a kilogram is a unit of mass, not volume. Choice B, 1 quart, is a non-metric unit of volume and is not equivalent to 1 liter. Choice C, 1 milliliter, is too small to be equivalent to 1 liter; it takes 1000 milliliters to make up 1 liter.

4. What is 0.05 mcg in mg?

• A. 0.00005 mg
• B. 0.0005 mg
• C. 0.005 mg
• D. 0.05 mg

Correct answer: A

Rationale: To convert micrograms (mcg) to milligrams (mg), you need to divide by 1000. Therefore, 0.05 mcg equals 0.00005 mg. This conversion is crucial in the medical field to ensure accurate dosing. Choice B, 0.0005 mg, is incorrect as it represents 0.5 mcg. Choice C, 0.005 mg, is the equivalent of 5 mcg. Choice D, 0.05 mg, actually represents 50 mcg. It's important to pay attention to decimal placement and unit conversions to avoid medication errors.

5. How many grams are in 2 kilograms?

• A. 200 grams
• B. 2000 grams
• C. 20 grams
• D. 2 grams

Correct answer: B

Rationale: To convert kilograms to grams, you need to multiply by 1000 since there are 1000 grams in a kilogram. Therefore, 2 kilograms is equal to 2 x 1000 = 2000 grams. Choice A (200 grams) is incorrect as it represents the value of 0.2 kilograms. Choice C (20 grams) is incorrect as it represents the value of 0.02 kilograms. Choice D (2 grams) is incorrect as it represents the value of 0.002 kilograms.
