Nursing Metric Conversion Questions
Question 1 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 2 of 5
What is 0.5 liters to milliliters?
Correct Answer: A
Rationale: To convert liters to milliliters, you need to multiply by 1000 since 1 liter equals 1000 milliliters. So, 0.5 liters * 1000 = 500 ml. Therefore, the correct answer is A: 500 ml. Choice B (50 ml) is incorrect as it is 10 times less than the correct answer. Choice C (5 ml) is incorrect as it is 100 times less, and choice D (0.5 ml) is incorrect as it is the original volume in milliliters, not the conversion from liters.
Question 3 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 4 of 5
What is 0.07 expressed as a fraction?
Correct Answer: A
Rationale: To express 0.07 as a fraction, we consider the decimal places. Since there are two decimal places in 0.07, we write it as 7/100. This simplifies to 7/100 as the correct fraction. Option A is correct as it represents 0.07 accurately. Options B, C, and D are incorrect as they do not match the decimal value of 0.07. B is 1/10, C is 1/20, and D is 1/50, which are not equivalent to 0.07.
Question 5 of 5
What is the equivalent of 3,450 milliliters in liters (L)?
Correct Answer: B
Rationale: To convert milliliters to liters, we divide by 1000 since 1 liter is equal to 1000 milliliters. Therefore, 3450 milliliters / 1000 = 3.45 liters. Choice B is correct. Choice A is incorrect as it is off by a factor of 10. Choice C is incorrect as it is off by a factor of 100. Choice D is incorrect as it is off by a factor of 1000.
