Metric Conversions for Nursing Questions

Question 1 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.

Question 2 of 5

What is the conversion factor from milliliters to liters?

Correct Answer: A

Rationale: The conversion factor from milliliters to liters is 0.001 liters. This is because there are 1000 milliliters in 1 liter. To convert milliliters to liters, you need to divide the number of milliliters by 1000. Therefore, 1 milliliter is equal to 0.001 liters. Summary: Choice A (0.001 liters) is correct because it accurately reflects the conversion factor. Choices B, C, and D are incorrect as they do not align with the correct conversion ratio of 1 liter being equivalent to 1000 milliliters.

Question 3 of 5

What does the prefix 'Tera' refer to?

Correct Answer: A

Rationale: The prefix 'Tera' corresponds to the value of 10^12. This can be understood by knowing that the International System of Units (SI) prefixes are based on powers of 10. 'Tera' comes after 'Giga' (10^9) and before 'Peta' (10^15). Therefore, the correct choice is A. Summary of other choices: B: Incorrect because 'Giga' represents 10^9. C: Incorrect as 'Peta' represents 10^15, a higher value. D: Incorrect because 'Mega' represents 10^6, a lower value than 'Tera'.

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

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.
