Nursing Metric Conversion

Correct Answer: A

Rationale: The correct answer is A: millimeter. In the metric system, 'mm' stands for millimeter, which is a unit of length equal to one thousandth of a meter. This is the correct answer because "milli-" is a prefix in the metric system that denotes one thousandth. Megabyte (B) is a unit of digital information storage, not length. Millipede (C) refers to a type of arthropod, not a unit of measurement. Metered (D) is not a recognized unit in the metric system for length.

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, which is choice B. Choices A, C, and D are incorrect because they do not follow the correct conversion factor from liters to milliliters.

Correct Answer: C

Rationale: To convert milliliters to liters, you divide by 1000 since 1 liter equals 1000 milliliters. Therefore, 3000 milliliters divided by 1000 equals 3 liters. Choice C is correct. Choice A is incorrect as it represents 0.3 liters, which is the result of dividing by 10. Choice B is incorrect as it represents 30 liters, which is the result of multiplying by 10. Choice D is incorrect as it represents 0.03 liters, which is the result of dividing by 100.

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.

Correct Answer: B

Rationale: The correct answer is B: 2 pints in one quart. A quart is equivalent to 2 pints. This is because there are 2 pints in a quart by definition. To convert pints to quarts, you divide the number of pints by 2. Therefore, the correct answer is 2 pints. Choices A, C, and D are incorrect because they do not align with the conversion factor of 2 pints in one quart. Answer A is too low, C is too high, and D is also too high based on the conversion factor.
