Nursing Metric Conversion Questions
Question 1 of 5
What is 0.04 grams converted to milligrams?
Correct Answer: A
Rationale: To convert grams to milligrams, you need to multiply by 1000 since there are 1000 milligrams in a gram. So, 0.04 grams * 1000 = 40 milligrams. Therefore, the correct answer is A: 40 mg. Incorrect choices: B: 4 mg - This is incorrect because it does not account for the conversion factor of 1000. C: 400 mg - This is incorrect as it is a result of multiplying by 10 instead of 1000. D: 0.4 mg - This is incorrect as it is the result of dividing by 10 instead of multiplying by 1000.
Question 2 of 5
Convert 25 millimeters to centimeters.
Correct Answer: D
Rationale: To convert millimeters to centimeters, we divide by 10 since there are 10 millimeters in 1 centimeter. Therefore, 25 mm / 10 = 2.5 cm. The correct answer is D: 25 mm, as it represents the initial quantity to be converted. Choices A and B are incorrect as they do not follow the conversion factor. Choice C is incorrect as it represents the original unit rather than the converted unit.
Question 3 of 5
What is 0.004 as a ratio?
Correct Answer: B
Rationale: To express 0.004 as a ratio, we can consider it as 4/1000. Simplifying this gives us 1/250. Therefore, the correct ratio is 1:250. Choice A is incorrect as it simplifies to 1:2. Choice C simplifies to 1:4. Choice D is equivalent to 4:0, which is undefined in ratio form. The correct answer, B, accurately represents 0.004 as a ratio of 1:250.
Question 4 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 5 of 5
How many meters are in one kilometer?
Correct Answer: B
Rationale: The correct answer is B: 1000 meters in one kilometer. This is because the prefix "kilo-" in the metric system represents a factor of 1000. Therefore, one kilometer is equal to 1000 meters. The other choices are incorrect because they do not align with the standard metric conversion for kilometer. Choice A (100 meters) is too small, choice C (500 meters) is an arbitrary number, and choice D (2000 meters) is double the correct conversion. Thus, the correct answer is B based on the standard metric system conversion.
