Nursing Metric Conversion

Correct Answer: C

Rationale: To find the result of multiplying 0.15 by 3, we simply multiply the two numbers together. 0.15 * 3 = 0.45. This is because when you multiply a decimal by a whole number, you multiply the decimal part as usual and then place the decimal point in the product according to the total number of decimal places in the numbers being multiplied. In this case, 0.15 has two decimal places, and 3 is a whole number, so the product is 0.45. Choice A (0.05) is incorrect as it is the result of multiplying 0.15 by 0.33, not 3. Choice B (0.15) is incorrect as it is the original number being multiplied, not the result. Choice D (0.45) is incorrect as it is the same as the correct answer, but repeated in the choices, which usually does not happen in multiple-choice questions.

Correct Answer: B

Rationale: The correct answer is B: 1000 meters in one kilometer. This is because the prefix "kilo-" in the metric system represents a factor of 1000. Therefore, one kilometer is equal to 1000 meters. The other choices are incorrect because they do not align with the standard metric conversion for kilometer. Choice A (100 meters) is too small, choice C (500 meters) is an arbitrary number, and choice D (2000 meters) is double the correct conversion. Thus, the correct answer is B based on the standard metric system conversion.

Correct Answer: B

Rationale: To convert milliliters to liters, we divide by 1000 since 1 liter is equal to 1000 milliliters. Therefore, 3450 milliliters / 1000 = 3.45 liters. Choice B is correct. Choice A is incorrect as it is off by a factor of 10. Choice C is incorrect as it is off by a factor of 100. Choice D is incorrect as it is off by a factor of 1000.

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: 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.
