Nursing Metric Conversions Questions

Question 1 of 5

Convert 0.004 to a ratio.

Correct Answer: A

Rationale: To convert 0.004 to a ratio, we need to express it in the form of a fraction. 0.004 as a fraction is 4/1000, which simplifies to 1/250. Therefore, the correct ratio is 1:250. Choice A is correct as it represents the simplified form of 0.004. Choices B, C, and D are incorrect as they do not accurately represent the conversion of 0.004 to a ratio.

Question 2 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 3 of 5

What does 'km' stand for in the metric system?

Correct Answer: A

Rationale: The correct answer is A: kilometer. In the metric system, 'km' stands for kilometer, which is a unit of length equal to 1000 meters. This is because the prefix 'kilo-' signifies a factor of 1000. Kilomole (B) is not a standard metric unit. Kilobyte (C) is a unit of digital information storage, not length. Knot (D) is a unit of speed typically used in maritime and aviation contexts, not length. Therefore, A is the correct choice for 'km' in the metric system.

Question 4 of 5

How many pounds are in 1 ton?

Correct Answer: B

Rationale: The correct answer is B: 2000 pounds. There are 2000 pounds in 1 ton because a ton is equal to 2000 pounds. This conversion is based on the fact that 1 ton is equivalent to 2000 pounds in the imperial system of measurement. Therefore, to convert tons to pounds, you simply multiply the number of tons by 2000. Choice A (1000 pounds) is incorrect because it represents half a ton, not a full ton. Choice C (1500 pounds) and Choice D (2500 pounds) are also incorrect as they do not match the actual conversion factor of 2000 pounds in 1 ton.

Question 5 of 5

Convert 3.75 liters to milliliters.

Correct Answer: C

Rationale: To convert liters to milliliters, you need to multiply by 1000 since 1 liter is equal to 1000 milliliters. So, 3.75 liters x 1000 = 3750 milliliters. Therefore, the correct answer is C. Explanation for incorrect choices: A: 3.75 ml - This is the same value in milliliters, not a conversion. B: 375 ml - Incorrect conversion, as it should be 3750 ml. D: 37.5 ml - Incorrect conversion, it's missing a zero making it ten times less than the correct answer.
