Nursing Metric Conversion Questions

Question 1 of 5

How many centimeters are in 1 inch?

Correct Answer: A

Rationale: The correct answer is A: 2.54 cm. To convert inches to centimeters, we use the conversion factor 1 inch = 2.54 cm. This conversion factor is derived from the definition of an inch in the metric system. Therefore, there are 2.54 centimeters in 1 inch. Option B (3 cm) is incorrect because it does not align with the correct conversion factor of 1 inch = 2.54 cm. Option C (2 cm) is also incorrect as it does not match the accurate conversion. Option D (1 cm) is incorrect because it is not the correct conversion factor for inches to centimeters.

Question 2 of 5

How many meters are equivalent to 3 kilometers?

Correct Answer: B

Rationale: To convert kilometers to meters, you multiply by 1000. Therefore, to find how many meters are in 3 kilometers, you would multiply 3 by 1000, resulting in 3,000 meters. Choice B is correct. Choices A, C, and D are incorrect because they do not correctly apply the conversion factor of 1000 for converting kilometers to meters.

Question 3 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 4 of 5

What is 0.004 as a ratio?

Correct Answer: B

Rationale: To express 0.004 as a ratio, we can consider it as 4/1000. Simplifying this gives us 1/250. Therefore, the correct ratio is 1:250. Choice A is incorrect as it simplifies to 1:2. Choice C simplifies to 1:4. Choice D is equivalent to 4:0, which is undefined in ratio form. The correct answer, B, accurately represents 0.004 as a ratio of 1:250.

Question 5 of 5

What is 0.5 L converted to mL?

Correct Answer: A

Rationale: To convert 0.5 L to mL, you multiply by 1000 since there are 1000 mL in 1 L. 0.5 L * 1000 = 500 mL. Therefore, the correct answer is A: 500 mL. Option B, C, and D are incorrect as they do not follow the correct conversion factor.
