Nursing Metric Conversion - Nurselytic

Correct Answer: B

Rationale:
To convert millimeters to centimeters, you need to divide by 10 since there are 10 millimeters in 1 centimeter.
Therefore, 345,000 mm · 10 = 34,500 cm.
Choice A is incorrect because it is a factor of 10 higher than the correct answer.
Choice C is incorrect because it represents the original quantity in centimeters, not the converted value.
Choice D is incorrect as it erroneously multiplies the millimeters by 1,000 instead of dividing by 10 to convert to centimeters.

Correct Answer: B

Rationale:
To convert 0.004 to a ratio, first express it as a fraction by writing it as 4/1000. Simplifying this fraction gives 1/250.
Therefore, 0.004 as a ratio is 1:250.
Choice A (5:10) simplifies to 1:2, not equivalent to 0.004.
Choice C (7:28) does not simplify to a value close to 0.004.
Choice D (4:00) is not a valid ratio representation of 0.004.

Correct Answer: B

Rationale:
To convert kilograms to grams, you need to multiply by 1,000 since there are 1,000 grams in a kilogram.
Therefore, 35.40 kg 1,000 = 35,400 grams.
Choice A (354 g) is incorrect because it is off by a factor of 10.
Choice C (3,540 g) is incorrect as it is off by a factor of 100.
Choice D (3.54 g) is incorrect as it represents kilograms instead of grams.

Correct Answer: A

Rationale:
To convert liters to milliliters, you need to multiply by 1,000 since there are 1,000 milliliters in a liter. So, to convert 0.04 liters to milliliters, you would multiply 0.04 by 1,000, giving you 40 milliliters. This means that choice A, '40 ml', is the correct answer.

Choices B, C, and D are incorrect because they do not correctly convert liters to milliliters.
Choice B, '4 ml', is incorrect as it is 10 times smaller than the correct conversion.
Choice C, '400 ml', is incorrect as it is 10 times larger than the correct conversion.
Choice D, '0.4 ml', is incorrect as it is one-tenth of the correct conversion.

Correct Answer: B

Rationale: The correct answer is B: 15 ml. One tablespoon is equivalent to 15 milliliters. The conversion factor for tablespoons to milliliters is 1 tablespoon = 15 milliliters.
Choice A (10 ml) is incorrect because it is not the standard conversion for a tablespoon.
Choice C (5 ml) is incorrect as it is too low for a tablespoon.
Choice D (20 ml) is incorrect as it is too high for a tablespoon.
Therefore, the correct conversion is 15 milliliters for one tablespoon.
