Metric Conversions for Nursing Questions

Question 1 of 5

How many milliliters are in 2 liters?

Correct Answer: A

Rationale: To convert liters to milliliters, you multiply by 1000 because 1 liter = 1000 milliliters. Therefore, 2 liters x 1000 = 2000 milliliters. This is why choice A (2000 mL) is correct. Choices B, C, and D are incorrect because they do not correctly convert 2 liters to milliliters using the conversion factor of 1000. Choice B (20,000 mL) is 10 times the correct answer, choice C (200 mL) is 10 times less, and choice D (2 mL) is 1000 times less than the correct answer.

Question 2 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 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

What is 0.2 liters when converted to milliliters?

Correct Answer: B

Rationale: The correct answer is B: 200 ml. To convert liters to milliliters, you need to multiply by 1000 since 1 liter equals 1000 milliliters. Therefore, 0.2 liters x 1000 = 200 ml. A) 20 ml is incorrect as it is the result of incorrectly converting 0.02 liters. C) 2 ml is incorrect as it is the result of incorrectly converting 0.002 liters. D) 2000 ml is incorrect as it is the result of incorrectly converting 2 liters.

Question 5 of 5

Which of the following is equal to 0.16 inches?

Correct Answer: B

Rationale: To convert 0.16 inches to a fraction, we can write it as 16/100 or 4/25. Both 16/100 and 4/25 are equivalent to 0.16. Therefore, the correct answer is B: 0.16 inches. Option A (0.016 inches) is incorrect as it is one-tenth of the correct value. Option C (1.6 inches) is incorrect as it is ten times the correct value. Option D (16 inches) is incorrect as it is one hundred times the correct value.
