Metric Conversions for Nursing - Nurselytic

Correct Answer: A

Rationale: The correct answer is 'cubic meters' (
A) which is the base unit for volume of a solid in the metric system. Volume is measured in cubic units (length width height) for solids.
Choice B, 'meters cubed,' is not the standard way to express volume in the metric system.

Choices C and D, 'grams' and 'centimeters,' are units of mass and length respectively, not volume.

Correct Answer: B

Rationale:
To convert meters to centimeters, you multiply by 100. In this case, 4 meters x 100 = 400 centimeters.
Therefore, the correct answer is 400 cm.

Choices A, C, and D are incorrect because they do not correctly convert meters to centimeters.

Correct Answer: B

Rationale:
To convert 0.1 liters to milliliters, you need to multiply by 1000, not 10000.
Therefore, 0.1 liter converts to 100 ml.
Choice A (10 ml) is incorrect because it is the equivalent of 0.01 liter.
Choice C (1000 ml) is incorrect as it represents 1 liter.
Choice D (1 ml) is significantly less than the correct conversion.

Correct Answer: B

Rationale:
To convert grams to milligrams, you need to multiply by 1,000 because there are 1,000 milligrams in 1 gram.
Therefore, 1 gram 1,000 = 1,000 milligrams.
Choice A (100 mg) is incorrect as it represents 0.1 grams, not 1 gram.
Choice C (1 mg) is incorrect as it represents a fraction of a gram.
Choice D (10,000 mg) is incorrect as it is 10 times more than the correct conversion.

Correct Answer: A

Rationale: The prefix 'Tera' corresponds to a factor of 10^12, which is equivalent to one trillion. It is commonly used in various fields like data storage to denote large quantities.
Choice B, '10^9,' is incorrect as it corresponds to the prefix 'Giga.'
Choice C, '10^15,' is incorrect as it corresponds to the prefix 'Peta.'
Choice D, '10^6,' is incorrect as it corresponds to the prefix 'Mega.'
Therefore, the correct answer is A.
