Nursing Metric Conversions Questions

Question 1 of 5

How many ounces are in one gallon?

Correct Answer: B

Rationale: To convert gallons to ounces, we know that 1 gallon is equal to 128 fluid ounces. Therefore, the correct answer is B. Choice A (64 ounces) is incorrect as it represents half a gallon. Choice C (100 ounces) and D (150 ounces) do not correspond to the standard conversion of gallons to ounces.

Question 2 of 5

What is 0.3 as a fraction in simplest form?

Correct Answer: A

Rationale: To express 0.3 as a fraction, we can write it as 3/10. This is because 0.3 can be seen as 3 tenths, which simplifies to 3/10 in its simplest form. To simplify, we divide both the numerator and denominator by their greatest common factor, which is 1 in this case. Therefore, the correct answer is A: 3/10. Choice B: 1/3 is incorrect because 0.3 is not equivalent to one third. Choice C: 1/4 is incorrect as 0.3 is not equal to one fourth. Choice D: 1/5 is incorrect as 0.3 is not equal to one fifth.

Question 3 of 5

What is the equivalent of 35.4 centimeters in kilometers (km)?

Correct Answer: B

Rationale: To convert 35.4 centimeters to kilometers, we need to divide by 100, as there are 100 centimeters in a meter and 1000 meters in a kilometer. Therefore, 35.4 cm ÷ 100 = 0.354 meters. To convert meters to kilometers, we divide by 1000, so 0.354 m ÷ 1000 = 0.000354 km, which is choice B. Choices A, C, and D are incorrect as they do not follow the correct conversion factor.

Question 4 of 5

How many liters are in 2,000 milliliters?

Correct Answer: B

Rationale: To convert milliliters to liters, divide by 1000 since 1 liter = 1000 milliliters. So, 2000 milliliters ÷ 1000 = 2 liters. Choice B is correct. Choice A is incorrect as it's 0.2 liters (misplaced decimal). Choice C is incorrect as it's 0.02 liters (decimal off by a factor of 10). Choice D is incorrect as it's 20 liters (decimal misplaced).

Question 5 of 5

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

Correct Answer: A

Rationale: The correct answer is A: meter. In the metric system, 'm' stands for meter, which is the base unit of length. Mole (B) is a unit of amount of substance, milli (C) represents a prefix meaning one-thousandth, and micro (D) represents a prefix meaning one-millionth. Therefore, A is the correct choice as it directly corresponds to the unit of length in the metric system.
