Nursing Metric Conversion Questions

Question 1 of 5

Convert 25 millimeters to centimeters.

Correct Answer: D

Rationale: To convert millimeters to centimeters, we divide by 10 since there are 10 millimeters in 1 centimeter. Therefore, 25 mm / 10 = 2.5 cm. The correct answer is D: 25 mm, as it represents the initial quantity to be converted. Choices A and B are incorrect as they do not follow the conversion factor. Choice C is incorrect as it represents the original unit rather than the converted unit.

Question 2 of 5

What is the equivalent of 255.0 pounds in kilograms (1 kg = 2.205 lbs)?

Correct Answer: D

Rationale: To convert pounds to kilograms, divide the weight in pounds by the conversion factor (2.205 lbs/kg). So, 255 lbs ÷ 2.205 lbs/kg = 115.60 kg, which is closest to choice D (115.6 kg). This choice is correct as it accurately converts 255 pounds to kilograms. The other choices are incorrect because they do not provide the correct conversion based on the given conversion factor.

Question 3 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 4 of 5

What does 'L' stand for in the metric system?

Correct Answer: A

Rationale: The correct answer is A: liter. In the metric system, 'L' stands for liter, which is a unit of volume. The liter is commonly used to measure liquid volumes. The other choices, B: log, C: link, and D: lever, do not represent units of measurement in the metric system. Log is a mathematical function, link is a unit of distance in surveying, and lever is a simple machine. Therefore, the correct answer is A: liter, as it is the only choice that corresponds to a valid unit of measurement in the metric system.

Question 5 of 5

How many liters are in 750 milliliters?

Correct Answer: B

Rationale: To convert milliliters to liters, we divide by 1000 since there are 1000 milliliters in a liter. So, 750 milliliters ÷ 1000 = 0.75 liters. Therefore, the correct answer is B. Choice A is incorrect as it incorrectly moves the decimal point. Choices C and D are incorrect as they incorrectly add extra zeros and move the decimal point in the wrong direction.
