Nursing Metric Conversions

Correct Answer: B

Rationale: The correct answer is B: 0.001 m. The prefix 'milli' denotes a factor of 0.001 (10^-3). Therefore, 1 mm is equal to 0.001 meters. To convert millimeters to meters, we use the conversion factor 1 mm = 0.001 m. Choice A (0.01 m) is incorrect as it represents 1 centimeter, choice C (0.1 m) is incorrect as it represents 1 decimeter, and choice D (1 m) is incorrect as it represents 1 meter. The correct conversion from millimeters to meters is achieved by multiplying the value in millimeters by 0.001.

Correct Answer: C

Rationale: The metric prefix Tera is abbreviated as T- and represents 10^12, which means 1 trillion. Tera is derived from the Greek word for "monster" or "giant." Therefore, the correct numerical value for Tera is 10^12. Choice A (10^6) is incorrect as it represents the metric prefix "Mega." Choice B (10^9) is incorrect as it represents the metric prefix "Giga." Choice D (10^3) is incorrect as it represents the metric prefix "Kilo."

Correct Answer: B

Rationale: To convert liters to milliliters, you need to multiply by 1000 because there are 1000 milliliters in 1 liter. So, 3,540 liters x 1000 = 3,540,000 mL. Therefore, choice B (3,540,000 mL) is the correct answer. Choice A (354,000 mL) is incorrect because it doesn't account for the conversion factor. Choice C (35,400 mL) and choice D (35,400,000 mL) are also incorrect as they do not correctly apply the conversion factor.

Correct Answer: B

Rationale: To convert kilograms to grams, we must remember that 1 kilogram is equal to 1000 grams. Therefore, to find how many grams are in 2 kilograms, we multiply 2 by 1000, which equals 2000 grams. This makes choice B the correct answer. Choices A, C, and D are incorrect because they do not correctly convert kilograms to grams. Choice A is the result of mistakenly multiplying by 100 instead of 1000. Choice C is the result of dividing instead of multiplying. Choice D is simply the original amount in kilograms, without conversion.

Correct Answer: B

Rationale: To convert liters to milliliters, you need to multiply by 1000 since there are 1000 milliliters in 1 liter. Therefore, 0.5 liters x 1000 = 500 milliliters. So, the correct answer is B: 500 ml. Choice A (50 ml) is incorrect as it is the result of multiplying by 10 instead of 1000. Choice C (5 ml) is incorrect as it is the result of dividing by 10 instead of multiplying by 1000. Choice D (0.5 ml) is incorrect as it represents the original amount in milliliters instead of the converted value.
