Nursing Metric Conversion Questions
Question 1 of 5
Convert 345,000 millimeters to centimeters (cm).
Correct Answer: B
Rationale: To convert millimeters to centimeters, we divide by 10 since there are 10 millimeters in a centimeter. So, 345,000 mm ÷ 10 = 34,500 cm. Therefore, the correct answer is B. Choice A is incorrect as it doesn't involve dividing by 10. Choice C is incorrect as it doesn't consider the conversion factor. Choice D is incorrect as it adds extra zeros, which is not necessary for this conversion.
Question 2 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.
Question 3 of 5
What is 0.3 ml in tsp?
Correct Answer: A
Rationale: To convert 0.3 ml to tsp, we need to know that 1 ml is approximately 0.2 tsp. Therefore, 0.3 ml is 0.3 * 0.2 = 0.06 tsp. This is why choice A (0.06 tsp) is correct. Choices B, C, and D are incorrect because they do not follow the correct conversion ratio of 1 ml to 0.2 tsp. B is too high, C is double the correct answer, and D is the same as the original measurement in ml.
Question 4 of 5
What is the equivalent of 3,450 milliliters in liters (L)?
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.
Question 5 of 5
How many grams are in 0.5 kilograms?
Correct Answer: B
Rationale: To convert kilograms to grams, we need to multiply by 1000 since 1 kilogram equals 1000 grams. Therefore, 0.5 kilograms x 1000 = 500 grams. This is why choice B, 500 grams, is correct. Choice A, 50 grams, is incorrect as it is the result of multiplying by 10 instead of 1000. Choice C, 5,000 grams, is incorrect as it is the result of multiplying by 10,000 which is not the correct conversion factor. Choice D, 0.5 grams, is incorrect as it is the original amount in grams, not the converted amount from kilograms.
