Nursing Metric Conversion Questions
Question 1 of 5
What unit is used to measure density in the metric system?
Correct Answer: A
Rationale: Failed to generate a rationale after 5 retries.
Question 2 of 5
What is 1500 milliliters in liters?
Correct Answer: A
Rationale: To convert milliliters to liters, you need to divide by 1000 since there are 1000 milliliters in 1 liter. Therefore, 1500 milliliters divided by 1000 equals 1.5 liters. Choice A (1.5 liters) is correct because it accurately represents the conversion. Choices B, C, and D are incorrect because they do not follow the correct conversion factor of dividing by 1000. Choice B (0.15 liters) is one decimal place off, choice C (15 liters) is an order of magnitude too high, and choice D (0.015 liters) is two decimal places off.
Question 3 of 5
What does 'mg' stand for in the metric system?
Correct Answer: B
Rationale: The correct answer is B: milligram. In the metric system, 'mg' stands for milligram, which is a unit of mass equal to one thousandth of a gram. To determine the correct answer, you need to understand the metric prefixes. 'Micro' means one millionth, 'milli' means one thousandth, 'giga' means one billion, and 'mega' means one million. Therefore, A is incorrect because 'micro' is smaller than 'milli', C is incorrect because 'giga' is much larger than 'milli', and D is incorrect because 'megagram' is a unit equal to one million grams, not milligrams.
Question 4 of 5
Which metric prefix represents 10^-2?
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.
Question 5 of 5
How many ounces are in 0.5 liters?
Correct Answer: A
Rationale: To convert liters to ounces, we need to know that 1 liter is approximately 33.814 ounces. Therefore, 0.5 liters is 0.5 x 33.814 = 16.907 ounces, which is rounded to 16.91 oz. Choice A is correct because it accurately represents the conversion. Choices B, C, and D are incorrect as they do not reflect the accurate conversion from liters to ounces.
