Metric Conversions for Nursing Questions

Question 1 of 5

How many millimeters are in 5 centimeters?

Correct Answer: B

Rationale: To convert centimeters to millimeters, we multiply by 10 since there are 10 millimeters in 1 centimeter. Therefore, 5 cm x 10 = 50 mm. Thus, the correct answer is A. Option B (500 mm) is incorrect as it is the result of multiplying 5 cm by 100 instead of 10. Option C (5 mm) is incorrect as it represents the original value in centimeters, not the converted value in millimeters. Option D (500 cm) is incorrect as it is the original value in centimeters, not the converted value in millimeters.

Question 2 of 5

Convert 5 kilometers to meters.

Correct Answer: C

Rationale: To convert 5 kilometers to meters, you need to multiply by 1000 since 1 kilometer is equal to 1000 meters. Therefore, 5 kilometers x 1000 = 5000 meters. Choice C (5000 meters) is the correct answer. Choices A, B, and D are incorrect because they do not follow the correct conversion factor from kilometers to meters.

Question 3 of 5

Convert 0.07 to a fraction.

Correct Answer: A

Rationale: To convert 0.07 to a fraction, we note that 0.07 = 7/100. The rationale is to move the decimal two places to the right to get the numerator and place it over 100 (10^2) to get the denominator. Option A (7/100) is correct. Option B (1/10) is incorrect because it represents 0.1, not 0.07. Option C (1/20) is incorrect as it represents 0.05. Option D (1/50) is incorrect as it represents 0.02.

Question 4 of 5

How many millimeters (mm) are in 3.45 meters?

Correct Answer: B

Rationale: The correct answer is B: 3,450 mm. To convert meters to millimeters, we know that 1 meter is equal to 1,000 millimeters. Therefore, to find how many millimeters are in 3.45 meters, we multiply 3.45 by 1,000, which equals 3,450 mm. Incorrect choices: A: 345 mm - Incorrect because it is the result of multiplying 3.45 by 100 (not 1,000). C: 345,000 mm - Incorrect as it is the result of incorrectly multiplying 3.45 by 100,000. D: 3.45 mm - Incorrect as it is the original amount in meters, not the converted amount in millimeters.

Question 5 of 5

How many millimeters are in 5 centimeters?

Correct Answer: B

Rationale: To convert centimeters to millimeters, we multiply by 10 since there are 10 millimeters in 1 centimeter. Therefore, 5 cm x 10 = 50 mm. Thus, the correct answer is A. Option B (500 mm) is incorrect as it is the result of multiplying 5 cm by 100 instead of 10. Option C (5 mm) is incorrect as it represents the original value in centimeters, not the converted value in millimeters. Option D (500 cm) is incorrect as it is the original value in centimeters, not the converted value in millimeters.
