Nursing Metric Conversion Questions

Question 1 of 5

What is 1500 milliliters in liters?

Correct Answer: A

Rationale: To convert milliliters to liters, you need to divide by 1000 since there are 1000 milliliters in 1 liter. Therefore, 1500 milliliters divided by 1000 equals 1.5 liters. Choice A (1.5 liters) is correct because it accurately represents the conversion. Choices B, C, and D are incorrect because they do not follow the correct conversion factor of dividing by 1000. Choice B (0.15 liters) is one decimal place off, choice C (15 liters) is an order of magnitude too high, and choice D (0.015 liters) is two decimal places off.

Question 2 of 5

What is 0.02 as a ratio?

Correct Answer: C

Rationale: To express 0.02 as a ratio, we need to convert it to a fraction: 0.02 = 2/100. Simplifying this fraction gives us 2:100, which is the same as 2/100 or 1/50. Therefore, the correct ratio for 0.02 is 2:100 (C). The other choices are incorrect because: A: 1:50 - Incorrect, as 0.02 is equivalent to 2:100, not 1:50. B: 1:20 - Incorrect, as 0.02 is equivalent to 2:100, not 1:20. D: 4:20 - Incorrect, as 0.02 simplifies to 2:100, not 4:20.

Question 3 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 4 of 5

Which conversion is accurate?

Correct Answer: C

Rationale: The correct answer is C because 1 liter is equivalent to 1.057 quarts. To convert liters to quarts, we know that 1 liter is approximately equal to 1.057 quarts. This conversion is accurate because it reflects the actual conversion factor between liters and quarts. A: 1 inch = 2.54 cm, not 2.5 cm. B: 1 meter = 39.37 inches, not an incorrect conversion but not the most accurate one. D: 1 gram = 1000 milligrams, not 100 milligrams. In summary, choices A, B, and D are incorrect due to inaccurate conversion factors, whereas choice C is correct as it provides the accurate conversion between liters and quarts.

Question 5 of 5

How many meters are in one kilometer?

Correct Answer: B

Rationale: The correct answer is B: 1000 meters in one kilometer. This is because the prefix "kilo-" in the metric system represents a factor of 1000. Therefore, one kilometer is equal to 1000 meters. The other choices are incorrect because they do not align with the standard metric conversion for kilometer. Choice A (100 meters) is too small, choice C (500 meters) is an arbitrary number, and choice D (2000 meters) is double the correct conversion. Thus, the correct answer is B based on the standard metric system conversion.
