Metric Conversions for Nursing Questions
Question 1 of 5
How many mcg are there in 0.2 mg?
Correct Answer: B
Rationale: To convert milligrams (mg) to micrograms (mcg), you need to multiply by 1000. Therefore, to find how many mcg are in 0.2 mg, you would multiply 0.2 by 1000, which equals 200 mcg. Choice B is correct. Choices A, C, and D are incorrect as they do not accurately convert 0.2 mg to mcg. Choice A is too low, choice C is too high, and choice D is too low.
Question 2 of 5
How many milliliters are in 2 liters?
Correct Answer: C
Rationale: The correct answer is C: 2,000 mL. To convert liters to milliliters, you need to multiply by 1,000 since there are 1,000 milliliters in 1 liter. So, 2 liters x 1,000 mL = 2,000 mL. Explanation for Other Choices: A: 20 mL - This is incorrect as it is just 1% of 2 liters. B: 200 mL - This is also incorrect as it is 10% of 2 liters. D: 20,000 mL - This is incorrect as it is 10 times the correct answer, which is too large for 2 liters.
Question 3 of 5
What is 0.2 liters when converted to milliliters?
Correct Answer: B
Rationale: The correct answer is B: 200 ml. To convert liters to milliliters, you need to multiply by 1000 since 1 liter equals 1000 milliliters. Therefore, 0.2 liters x 1000 = 200 ml. A) 20 ml is incorrect as it is the result of incorrectly converting 0.02 liters. C) 2 ml is incorrect as it is the result of incorrectly converting 0.002 liters. D) 2000 ml is incorrect as it is the result of incorrectly converting 2 liters.
Question 4 of 5
Convert 1.5 kilometers to meters.
Correct Answer: A
Rationale: To convert kilometers to meters, you need to multiply by 1000 since 1 kilometer is equal to 1000 meters. So, 1.5 kilometers x 1000 = 1500 meters, which is choice A. Choice B (150 meters) is incorrect as it is the result if you mistakenly multiplied by 100 instead of 1000. Choice C (15,000 meters) is incorrect as it is the result of multiplying by 10,000. Choice D (1.5 meters) is incorrect as it represents the original distance in meters, not the converted value.
Question 5 of 5
Convert 1.25 kilograms to grams.
Correct Answer: C
Rationale: To convert kilograms to grams, you need to multiply by 1000 since there are 1000 grams in 1 kilogram. So, 1.25 kg x 1000 = 1250 grams, which is choice C. Choice A (12.5 grams) is incorrect as it is 10 times less than the correct answer. Choice B (125 grams) is incorrect as it is missing a zero. Choice D (1250 mg) is incorrect as it is in milligrams, not grams.
