Nursing Metric Conversion Questions

Question 1 of 5

How many pints are in one quart?

Correct Answer: B

Rationale: The correct answer is B: 2 pints in one quart. A quart is equivalent to 2 pints. This is because there are 2 pints in a quart by definition. To convert pints to quarts, you divide the number of pints by 2. Therefore, the correct answer is 2 pints. Choices A, C, and D are incorrect because they do not align with the conversion factor of 2 pints in one quart. Answer A is too low, C is too high, and D is also too high based on the conversion factor.

Question 2 of 5

What is 0.05 mcg in mg?

Correct Answer: A

Rationale: To convert micrograms (mcg) to milligrams (mg), we need to remember that 1 mcg is equal to 0.001 mg. Therefore, to convert 0.05 mcg to mg, we multiply 0.05 by 0.001 which gives us 0.00005 mg. This makes choice A the correct answer. Choices B, C, and D are incorrect because they do not correctly convert micrograms to milligrams based on the conversion factor of 0.001 mg per mcg.

Question 3 of 5

What is 0.07 expressed as a fraction?

Correct Answer: A

Rationale: To express 0.07 as a fraction, we consider the decimal places. Since there are two decimal places in 0.07, we write it as 7/100. This simplifies to 7/100 as the correct fraction. Option A is correct as it represents 0.07 accurately. Options B, C, and D are incorrect as they do not match the decimal value of 0.07. B is 1/10, C is 1/20, and D is 1/50, which are not equivalent to 0.07.

Question 4 of 5

What is 0.5 liters in milliliters?

Correct Answer: A

Rationale: To convert liters to milliliters, you need to multiply by 1000 since 1 liter is equal to 1000 milliliters. Therefore, 0.5 liters x 1000 = 500 milliliters. So, the correct answer is A: 500 ml. Explanation of other choices: B: 50 ml - Incorrect, this would be the equivalent of 0.05 liters. C: 5 ml - Incorrect, this would be the equivalent of 0.005 liters. D: 0.5 ml - Incorrect, this is the same value as the given amount in liters, not the conversion to milliliters.

Question 5 of 5

In the metric system, what factor does the prefix kilo- represent?

Correct Answer: A

Rationale: The prefix kilo- in the metric system represents the factor of 10^3. Kilo- means one thousand, so when used in conjunction with a base unit, it signifies that the value is being multiplied by 1000. For example, 1 kilometer is equal to 1000 meters. Therefore, the correct answer is A: 10^3. Choice B (10^2) is incorrect because this factor corresponds to the prefix hecto-, not kilo-. Choice C (10^4) is incorrect as it does not align with the meaning of kilo-, which specifically denotes a factor of 10^3. Choice D (10^6) is incorrect as it represents the prefix mega-, which signifies a factor of 10^6.
