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 0.05 mg in mcg?

Correct Answer: A

Rationale: To convert mg to mcg, we multiply by 1000. So, 0.05 mg x 1000 = 50 mcg. Therefore, the correct answer is A: 50 mcg. Choice B (500 mcg) is incorrect as it would be the result if we mistakenly multiplied by 10, not 1000. Choice C (5 mcg) is incorrect as it represents the original value in mcg, not the converted value. Choice D (0.5 mcg) is incorrect as it is the result if we mistakenly divided by 1000 instead of multiplying.

Question 3 of 5

How many milliliters are in 0.5 liters?

Correct Answer: A

Rationale: To convert liters to milliliters, you need to multiply by 1000 since there are 1000 milliliters in 1 liter. Therefore, to find how many milliliters are in 0.5 liters, you would multiply 0.5 by 1000 which equals 500 ml. This makes choice A, 500 ml, the correct answer. Choices B, C, and D are incorrect because they do not correctly convert liters to milliliters. Choice B (50 ml) is 10 times less than the correct answer, choice C (5 ml) is 100 times less, and choice D (0.5 ml) is 1000 times less than the correct answer.

Question 4 of 5

How many grams are in one kilogram?

Correct Answer: B

Rationale: The correct answer is B: 1000 grams. This is because there are 1000 grams in one kilogram. The prefix "kilo-" signifies 1000 in the metric system. Therefore, when converting from kilograms to grams, we multiply by 1000. The other choices are incorrect because A (100 grams) is the conversion from decagrams to grams, C (500 grams) is not the correct conversion from kilograms, and D (2000 grams) is the equivalent of 2 kilograms, not 1 kilogram. Thus, B is the correct answer.

Question 5 of 5

What is 0.5 liters converted 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. So, the correct answer is B: 500 ml. Choice A (50 ml) is incorrect as it is the result of multiplying by 10 instead of 1000. Choice C (5 ml) is incorrect as it is the result of dividing by 10 instead of multiplying by 1000. Choice D (0.5 ml) is incorrect as it represents the original amount in milliliters instead of the converted value.
