Nursing Metric Conversions Questions

Question 1 of 5

How many milliliters are in 1.5 liters?

Correct Answer: B

Rationale: To convert liters to milliliters, you need to multiply by 1000 since 1 liter = 1000 milliliters. Therefore, 1.5 liters x 1000 = 1500 milliliters. So, the correct answer is B: 1,500 mL. A is incorrect as it is 10 times less than the correct answer. C is incorrect as it is 10 times less than the correct answer. D is incorrect as it is 100 times more than the correct answer.

Question 2 of 5

What is 0.26 as a fraction in simplest form?

Correct Answer: A

Rationale: To convert 0.26 to a fraction, we can write it as 26/100 since 0.26 is equivalent to 26 hundredths. To simplify this fraction, we divide the numerator and denominator by their greatest common divisor, which is 2. Therefore, 26/100 simplifies to 13/50. This is the correct answer (A) in simplest form. Choice B (26/100) is the initial form of 0.26 but not in simplest form as it can be further simplified to 13/50. Choice C (26/1000) is incorrect as the decimal 0.26 is equivalent to 26/100, not 26/1000. Choice D (1/4) is not equivalent to 0.26.

Question 3 of 5

How many yards are in one mile?

Correct Answer: A

Rationale: Certainly! The correct answer is A: 1760 yards in one mile. This is because there are 1760 yards in a mile, as defined by the international yard agreement. This conversion is widely accepted and used in various fields. Choices B, C, and D are incorrect as they do not align with the standard conversion of yards to a mile. B, C, and D do not accurately reflect the established measurement and would lead to incorrect calculations in real-world scenarios.

Question 4 of 5

How many milligrams are in 1 gram?

Correct Answer: D

Rationale: The correct answer is D: 1,000 mg. This is because there are 1,000 milligrams in 1 gram. This conversion is based on the metric system, where the prefix "milli-" represents one thousandth of the base unit. Therefore, 1 gram is equal to 1,000 milligrams. Explanation for other choices: A: 1 mg - This is incorrect as 1 mg is one-thousandth of a gram, not the other way around. B: 10 mg - This is incorrect as it is too small to be equivalent to 1 gram. C: 100 mg - This is incorrect as it is one-tenth of 1 gram, not the correct conversion.

Question 5 of 5

What is the formula to convert Celsius to Fahrenheit?

Correct Answer: A

Rationale: The correct formula to convert Celsius to Fahrenheit is A: (C * 9/5) + 32. To convert Celsius to Fahrenheit, you first multiply the Celsius temperature by 9/5 to get the equivalent in Fahrenheit scale, then add 32 to adjust for the offset between the two scales. This formula correctly accounts for both the scaling factor and the offset. Choices B, C, and D have incorrect scaling factors or offsets, leading to inaccurate conversions. B uses the incorrect scaling factor, C and D incorrectly subtract 32 instead of adding it.
