Nursing Metric Conversions Questions
Question 1 of 5
What is 0.16 as a fraction?
Correct Answer: C
Rationale: To convert 0.16 to a fraction, we consider the decimal places. Since 0.16 has 2 decimal places, we write it as 16/100. Simplifying by dividing both numerator and denominator by 4, we get 4/25. Therefore, the correct answer is C. Option A is incorrect as it does not simplify to the simplest form. Option B is incorrect as it has an additional zero in the denominator. Option D is incorrect as it simplifies to 2/25, not 4/25.
Question 2 of 5
What is 0.2 rounded to the nearest tenth?
Correct Answer: B
Rationale: The number 0.2 rounded to the nearest tenth means rounding to one decimal place. Since the digit after the tenths place is 0, we keep the tenths place as it is. Therefore, the correct answer is B: 0.2. A: 0.1 - Incorrect, this is rounding down to the nearest tenth. C: 0.3 - Incorrect, this is rounding up to the nearest tenth. D: 0.25 - Incorrect, this is rounding to the nearest hundredth, not tenth.
Question 3 of 5
What is the correct formula to convert Fahrenheit to Celsius?
Correct Answer: B
Rationale: The correct formula to convert Fahrenheit to Celsius is C = (F - 32) x 5/9. To convert Fahrenheit to Celsius, you subtract 32 from the Fahrenheit temperature and then multiply by 5/9. This is because the freezing point of water is 32°F and 0°C, and the slope of the Fahrenheit to Celsius conversion is 5/9. Choice A (F = (C x 9/5) + 32) incorrectly reverses the formula for converting Celsius to Fahrenheit. Choice C (C = (F - 32) x 9/5) incorrectly uses the wrong multiplier. Choice D (F = (C + 32) x 5/9) incorrectly adds 32 before multiplying by 5/9.
Question 4 of 5
How many millimeters are in 1 centimeter?
Correct Answer: B
Rationale: The correct answer is B: 10 mm. 1 centimeter is equal to 10 millimeters. This is because the metric system is based on units of 10. Therefore, to convert from centimeters to millimeters, you simply multiply by 10. The other choices are incorrect because: A: 1 mm - This is the equivalent of 1 millimeter, not 1 centimeter. C: 100 mm - This is the equivalent of 100 millimeters, not 1 centimeter. D: 1,000 mm - This is the equivalent of 1,000 millimeters, not 1 centimeter.
Question 5 of 5
What is the equivalent of 0.3 milliliters?
Correct Answer: B
Rationale: The correct answer is B: 0.3 ml. To convert milliliters to milliliters, we don't need to change the value. Therefore, the equivalent of 0.3 milliliters is still 0.3 ml. A: 0.03 ml - This is incorrect as it represents a value that is one-tenth of the original amount. C: 3 ml - This is incorrect as it represents a value that is 10 times greater than the original amount. D: 30 ml - This is incorrect as it represents a value that is 100 times greater than the original amount.
