Metric Conversions for Nursing Questions
Question 1 of 5
Convert 0.29 pounds to ounces.
Correct Answer: B
Rationale: To convert pounds to ounces, you need to know that 1 pound is equal to 16 ounces. So, to convert 0.29 pounds to ounces, you multiply 0.29 by 16. This gives you 4.64 ounces, which is the correct answer (B). Choices A, C, and D are incorrect because they do not correctly apply the conversion factor of 16 ounces per pound.
Question 2 of 5
What is the equivalent of 3.54 millimeters in meters (m)?
Correct Answer: B
Rationale: To convert millimeters to meters, we divide by 1000 since there are 1000 millimeters in a meter. Therefore, 3.54 mm in meters is 3.54/1000 = 0.00354 meters. Choice B is correct as it correctly converts 3.54 mm to meters. Choices A, C, and D are incorrect because they do not apply the correct conversion factor. Choice A incorrectly moves the decimal point two places to the left instead of three. Choice C incorrectly multiplies by 10 instead of dividing by 1000. Choice D incorrectly moves the decimal point one place to the left instead of three.
Question 3 of 5
What is 0.875 as a simplified fraction?
Correct Answer: A
Rationale: To convert 0.875 to a fraction, we note that it is 875/1000. Simplifying this gives 7/8, making A the correct answer. Choice B, 9/10, and C, 5/6, are incorrect as they do not equal 0.875 when converted to decimals. Choice D, 3/4, is also incorrect as it is not equivalent to 0.875.
Question 4 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 5 of 5
What does the prefix 'milli' mean?
Correct Answer: B
Rationale: The prefix 'milli' denotes 1/1000, which is equivalent to 0.001. This means that any unit following 'milli' is divided by 1000. Therefore, the correct answer is B, 0.001. Choice A (0.01) is incorrect as it represents the prefix 'centi,' which means 1/100. Choice C (0.0001) is incorrect as it represents the prefix 'micro,' which means 1/1,000,000. Choice D (0.00001) is incorrect as it represents the prefix 'nano,' which means 1/1,000,000,000.
