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

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

Convert 0.5 liters to milliliters.

Correct Answer: B

Rationale: To convert liters to milliliters, you need to multiply by 1000 since there are 1000 milliliters in 1 liter. Therefore, 0.5 liters x 1000 = 500 milliliters, which is choice B. Choices A, C, and D are incorrect because they do not follow the correct conversion factor from liters to milliliters.

Question 4 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 5 of 5

What is the equivalent temperature in Kelvin if the temperature is measured at 25 degrees Celsius?

Correct Answer: A

Rationale: To convert Celsius to Kelvin, add 273.15. So, for 25°C, add 273.15 to get 298.15 K (Choice A). Choice B (273.15 K) is the freezing point of water in Kelvin, not the correct conversion for 25°C. Choices C (250 K) and D (25 K) are incorrect as they do not follow the correct conversion formula.
