1. How many centimeters are in one meter?

• A. 1/10 cm
• B. 100 cm
• C. 10 cm
• D. 1000 cm

Correct answer: B

Rationale: The correct answer is B: 100 cm. One meter is equivalent to 100 centimeters. This conversion is based on the metric system, where the prefix 'centi-' represents one hundredth. Choices A, C, and D are incorrect because they do not accurately reflect the conversion of meters to centimeters. Choice A, '1/10 cm,' is incorrect as it represents a fraction of a centimeter, not the full conversion from meters to centimeters. Choice C, '10 cm,' is incorrect as it represents the conversion from decimeters to centimeters, not meters to centimeters. Choice D, '1000 cm,' is incorrect as it represents the conversion from meters to millimeters, not centimeters.

2. How many millimeters are in 5 centimeters?

• A. 50 mm
• B. 500 mm
• C. 5 mm
• D. 500 cm

Correct answer: B

Rationale: To convert centimeters to millimeters, you multiply by 10 since there are 10 millimeters in a centimeter. Therefore, 5 centimeters x 10 = 50 millimeters, making choice A the correct answer. Choice C, '5 mm,' is incorrect as it represents the original quantity in millimeters. Choice D, '500 cm,' is incorrect as it converts the centimeters to centimeters instead of millimeters.

3. Convert 0.075 mg to micrograms.

• A. 75 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, not 10000. Therefore, to convert 0.075 mg to mcg, you multiply 0.075 by 1000, giving you 75 mcg. The correct answer is not provided in the choices, and the correct conversion is 75 mcg, which is not listed as an option. Choices A, B, and C are incorrect because they do not reflect the correct conversion factor. Choice D, 750 mcg, is a common mistake made by incorrectly adding a zero. It is important to remember that the conversion from milligrams to micrograms involves multiplying by 1000, not adding extra zeros.

4. How many cups are in one pint?

• A. 1 cup
• B. 2 cups
• C. 3 cups
• D. 4 cups

Correct answer: B

Rationale: One pint is equivalent to 2 cups. This conversion is a common measurement in cooking and baking. Choice A (1 cup), Choice C (3 cups), and Choice D (4 cups) are incorrect because a pint specifically contains 2 cups according to standard measurement conversions.

5. 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.
