Nursing Metric Conversion Questions

Question 1 of 5

Convert 35.40 kilograms to grams (g).

Correct Answer: B

Rationale: To convert kilograms to grams, you need to multiply by 1000 since there are 1000 grams in 1 kilogram. Therefore, 35.40 kg x 1000 = 35,400 g (Choice B). This is the correct answer because it correctly applies the conversion factor. Choices A, C, and D are incorrect as they do not correctly convert kilograms to grams. Choice A is too small, Choice C is missing a zero, and Choice D incorrectly divides instead of multiplies.

Question 2 of 5

Is 0.25 mg equal to 250 mcg?

Correct Answer: A

Rationale: Step 1: Convert 0.25 mg to mcg: 0.25 mg * 1000 mcg/mg = 250 mcg Step 2: Compare the converted value (250 mcg) to 250 mcg. Step 3: Since the converted value matches 250 mcg, the statement "0.25 mg is equal to 250 mcg" is TRUE. Summary: - Option B (FALSE) is incorrect because the conversion shows they are equal. - Option C (Sometimes) doesn't apply as the conversion is a precise equivalence. - Option D (None of the above) is incorrect as option A is true based on the conversion.

Question 3 of 5

What is 0.3 ml in tsp?

Correct Answer: A

Rationale: To convert 0.3 ml to tsp, we need to know that 1 ml is approximately 0.2 tsp. Therefore, 0.3 ml is 0.3 * 0.2 = 0.06 tsp. This is why choice A (0.06 tsp) is correct. Choices B, C, and D are incorrect because they do not follow the correct conversion ratio of 1 ml to 0.2 tsp. B is too high, C is double the correct answer, and D is the same as the original measurement in ml.

Question 4 of 5

What is the result of multiplying 0.15 by 3?

Correct Answer: C

Rationale: To find the result of multiplying 0.15 by 3, we simply multiply the two numbers together. 0.15 * 3 = 0.45. This is because when you multiply a decimal by a whole number, you multiply the decimal part as usual and then place the decimal point in the product according to the total number of decimal places in the numbers being multiplied. In this case, 0.15 has two decimal places, and 3 is a whole number, so the product is 0.45. Choice A (0.05) is incorrect as it is the result of multiplying 0.15 by 0.33, not 3. Choice B (0.15) is incorrect as it is the original number being multiplied, not the result. Choice D (0.45) is incorrect as it is the same as the correct answer, but repeated in the choices, which usually does not happen in multiple-choice questions.

Question 5 of 5

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

Correct Answer: B

Rationale: The correct answer is B: milligram. In the metric system, 'mg' stands for milligram, which is a unit of mass equal to one thousandth of a gram. To determine the correct answer, you need to understand the metric prefixes. 'Micro' means one millionth, 'milli' means one thousandth, 'giga' means one billion, and 'mega' means one million. Therefore, A is incorrect because 'micro' is smaller than 'milli', C is incorrect because 'giga' is much larger than 'milli', and D is incorrect because 'megagram' is a unit equal to one million grams, not milligrams.
