Nursing Metric Conversion Questions
Question 1 of 5
What is the equivalent of 255.0 pounds in kilograms (1 kg = 2.205 lbs)?
Correct Answer: D
Rationale: To convert pounds to kilograms, divide the weight in pounds by the conversion factor (2.205 lbs/kg). So, 255 lbs ÷ 2.205 lbs/kg = 115.60 kg, which is closest to choice D (115.6 kg). This choice is correct as it accurately converts 255 pounds to kilograms. The other choices are incorrect because they do not provide the correct conversion based on the given conversion factor.
Question 2 of 5
What does 'mm' stand for in the metric system?
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.
Question 3 of 5
How many liters are in 3,000 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.
Question 4 of 5
What is 0.04 grams converted to milligrams?
Correct Answer: A
Rationale: To convert grams to milligrams, you need to multiply by 1000 since there are 1000 milligrams in a gram. So, 0.04 grams * 1000 = 40 milligrams. Therefore, the correct answer is A: 40 mg. Incorrect choices: B: 4 mg - This is incorrect because it does not account for the conversion factor of 1000. C: 400 mg - This is incorrect as it is a result of multiplying by 10 instead of 1000. D: 0.4 mg - This is incorrect as it is the result of dividing by 10 instead of multiplying by 1000.
Question 5 of 5
What is the result of multiplying 0.15 by 3?
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.
