Nursing Metric Conversions - Nurselytic

Correct Answer: A

Rationale: The correct answer is 'meter.' In the metric system, 'm' stands for meter, which is the base unit for length.
Choice B, 'mole,' is a unit used in chemistry to represent an amount of substance.
Choice C, 'milli,' represents a prefix indicating one-thousandth, and choice D, 'micro,' represents a prefix indicating one-millionth.
Therefore, the correct choice is 'A: meter.'

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.

Correct Answer: B

Rationale:
To convert grams to milligrams, you need to multiply by 1,000 since there are 1,000 milligrams in a gram.
Therefore, 2 grams is equal to 2,000 milligrams.
Choice A (200 mg) is incorrect as it represents 0.2 grams.
Choice C (20 mg) is incorrect as it represents 0.02 grams.
Choice D (20,000 mg) is incorrect as it represents 20 grams.

Correct Answer: B

Rationale: The correct formula for calculating the volume of a solid object is V = L x W x H, where L represents the length, W represents the width, and H represents the height.
Choice A (V = W/L) is incorrect as it represents a division operation, not multiplication.
Choice C (V = W/H) is incorrect as it does not account for the width and height.
Choice D (V = L/W) is incorrect as it represents the inverse operation of what is needed to calculate volume.

Correct Answer: A

Rationale:
To convert 0.3 to a fraction, we take 0.3 and express it as 3/10. This fraction is already in its simplest form because 3 and 10 do not have any common factors other than 1.
Choice B, 1/3, is incorrect as it represents a different value.
Choice C, 1/4, and
Choice D, 1/5, are also incorrect as they do not match the equivalent fraction for 0.3.
