Nursing Metric Conversion

Correct Answer: B

Rationale: To convert millimeters to meters, you divide by 1000 since there are 1000 millimeters in a meter. So, 354,000 mm ÷ 1000 = 354 m. Choice B is correct as it correctly converts millimeters to meters. Choice A is incorrect as it doesn't account for the conversion. Choice C is incorrect as it converts to kilometers instead of meters. Choice D is incorrect as it is a miscalculation of the conversion.

Correct Answer: A

Rationale: To convert liters to ounces, we need to know that 1 liter is approximately 33.814 ounces. Therefore, 0.5 liters is 0.5 x 33.814 = 16.907 ounces, which is rounded to 16.91 oz. Choice A is correct because it accurately represents the conversion. Choices B, C, and D are incorrect as they do not reflect the accurate conversion from liters to ounces.

Correct Answer: A

Rationale: To convert 0.5 L to mL, you multiply by 1000 since there are 1000 mL in 1 L. 0.5 L * 1000 = 500 mL. Therefore, the correct answer is A: 500 mL. Option B, C, and D are incorrect as they do not follow the correct conversion factor.

Correct Answer: A

Rationale: The correct answer is A: centi. The metric prefix "centi" represents 10^-2, which means one hundredth. This is because "centi" comes from the Latin word for hundred. Therefore, when using this prefix, the base unit is divided by 100. The other choices are incorrect because: B: milli represents 10^-3, which is one thousandth. C: nano represents 10^-9, which is one billionth. D: deci represents 10^-1, which is one-tenth.

Correct Answer: C

Rationale: To convert kilograms to grams, you need to multiply by 1000 since there are 1000 grams in 1 kilogram. So, 5 kilograms x 1000 = 5000 grams, which makes choice C the correct answer. Choices A, B, and D are incorrect as they do not correctly apply the conversion factor of 1000.
