Nursing Metric Conversion Questions
Question 1 of 5
Is 0.25 mg equal to 250 mcg?
Correct Answer: A
Rationale: Step 1: Convert 0.25 mg to mcg: 0.25 mg * 1000 mcg/mg = 250 mcg Step 2: Compare the converted value (250 mcg) to 250 mcg. Step 3: Since the converted value matches 250 mcg, the statement "0.25 mg is equal to 250 mcg" is TRUE. Summary: - Option B (FALSE) is incorrect because the conversion shows they are equal. - Option C (Sometimes) doesn't apply as the conversion is a precise equivalence. - Option D (None of the above) is incorrect as option A is true based on the conversion.
Question 2 of 5
What is 0.5 L converted to mL?
Correct Answer: A
Rationale: To convert 0.5 L to mL, you multiply by 1000 since there are 1000 mL in 1 L. 0.5 L * 1000 = 500 mL. Therefore, the correct answer is A: 500 mL. Option B, C, and D are incorrect as they do not follow the correct conversion factor.
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
How many milliliters are in 1 liter?
Correct Answer: C
Rationale: The correct answer is C: 1,000 mL. This is because there are 1,000 milliliters in 1 liter. This conversion is based on the metric system, where the prefix "milli-" represents one-thousandth of the base unit. In this case, the base unit is the liter. To convert from liters to milliliters, you multiply the number of liters by 1,000 since there are 1,000 milliliters in one liter. Therefore, 1 liter is equal to 1,000 milliliters. Choices A, B, and D are incorrect because they do not accurately represent the conversion factor between liters and milliliters.
Question 5 of 5
What is 0.5 liters to milliliters?
Correct Answer: A
Rationale: To convert liters to milliliters, you need to multiply by 1000 since 1 liter equals 1000 milliliters. So, 0.5 liters * 1000 = 500 ml. Therefore, the correct answer is A: 500 ml. Choice B (50 ml) is incorrect as it is 10 times less than the correct answer. Choice C (5 ml) is incorrect as it is 100 times less, and choice D (0.5 ml) is incorrect as it is the original volume in milliliters, not the conversion from liters.
