Nursing Metric Conversion

Correct Answer: C

Rationale: To convert mg to mcg, you multiply by 1000 since 1 mg = 1000 mcg. So, 0.175 mg x 1000 = 175 mcg. Therefore, the correct answer is C: 1750 mcg. Choices A, B, and D are incorrect because they do not correctly convert milligrams to micrograms.

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: A

Rationale: To convert liters to milliliters, we know that 1 liter is equal to 1000 milliliters. Therefore, 0.6 liters would be equal to 0.6 x 1000 = 600 milliliters. This makes choice A (600 ml) the correct answer. Choices B, C, and D are incorrect because they do not follow the correct conversion factor of 1 liter to 1000 milliliters. Choice B (60 ml) is ten times less than the correct answer, choice C (6 ml) is one hundred times less, and choice D (0.6 ml) is one thousand times less than the correct conversion.

Correct Answer: B

Rationale: To convert kilograms to grams, you need to multiply by 1000 since there are 1000 grams in 1 kilogram. Therefore, 35.40 kg x 1000 = 35,400 g (Choice B). This is the correct answer because it correctly applies the conversion factor. Choices A, C, and D are incorrect as they do not correctly convert kilograms to grams. Choice A is too small, Choice C is missing a zero, and Choice D incorrectly divides instead of multiplies.

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.
