Nursing Metric Conversions Questions

Question 1 of 5

What is 0.45 liters in milliliters?

Correct Answer: A

Rationale: To convert liters to milliliters, we multiply the value by 1000 because 1 liter equals 1000 milliliters. Therefore, 0.45 liters is equal to 0.45 x 1000 = 450 milliliters. Choice A (450 ml) is correct. Choices B, C, and D are incorrect because they do not follow the correct conversion factor from liters to milliliters.

Question 2 of 5

What is 0.05 mg in mcg?

Correct Answer: A

Rationale: To convert mg to mcg, we multiply by 1000. So, 0.05 mg x 1000 = 50 mcg. Therefore, the correct answer is A: 50 mcg. Choice B (500 mcg) is incorrect as it would be the result if we mistakenly multiplied by 10, not 1000. Choice C (5 mcg) is incorrect as it represents the original value in mcg, not the converted value. Choice D (0.5 mcg) is incorrect as it is the result if we mistakenly divided by 1000 instead of multiplying.

Question 3 of 5

Convert 0.5 centimeters to millimeters.

Correct Answer: A

Rationale: To convert centimeters to millimeters, you multiply by 10 since 1 cm = 10 mm. Therefore, 0.5 cm * 10 mm/cm = 5 mm. Choice A (5 mm) is correct. Choice B (0.5 mm) is incorrect as it represents the original value in millimeters. Choice C (50 mm) is incorrect as it is 10 times greater than the correct value. Choice D (0.05 mm) is incorrect as it is 100 times smaller than the correct value.

Question 4 of 5

What is 0.45 liters in milliliters?

Correct Answer: A

Rationale: To convert liters to milliliters, we multiply the value by 1000 because 1 liter equals 1000 milliliters. Therefore, 0.45 liters is equal to 0.45 x 1000 = 450 milliliters. Choice A (450 ml) is correct. Choices B, C, and D are incorrect because they do not follow the correct conversion factor from liters to milliliters.

Question 5 of 5

How many grams are in one kilogram?

Correct Answer: B

Rationale: The correct answer is B: 1000 grams. This is because there are 1000 grams in one kilogram. The prefix "kilo-" signifies 1000 in the metric system. Therefore, when converting from kilograms to grams, we multiply by 1000. The other choices are incorrect because A (100 grams) is the conversion from decagrams to grams, C (500 grams) is not the correct conversion from kilograms, and D (2000 grams) is the equivalent of 2 kilograms, not 1 kilogram. Thus, B is the correct answer.
