Metric Conversions for Nursing Questions

Question 1 of 5

Convert 100 grams to kilograms.

Correct Answer: A

Rationale: To convert grams to kilograms, divide the number of grams by 1000. In this case, 100 grams divided by 1000 equals 0.1 kilograms (A). Choice B is incorrect because it represents the equivalent of 1000 grams, not 100 grams. Choice C is incorrect as it represents 10 times the amount of 100 grams. Choice D is incorrect as it represents one-hundredth of 100 grams, not the correct conversion.

Question 2 of 5

Convert 0.0345 kilograms to grams (g).

Correct Answer: B

Rationale: To convert from kilograms to grams, you multiply the value in kilograms by 1000 since there are 1000 grams in one kilogram. Therefore, 0.0345 kg * 1000 = 34.5 grams. Choice B (34.5 grams) is correct. Choices A, C, and D are incorrect because they do not correctly convert kilograms to grams. Choice A is off by a factor of 10, choice C is off by a factor of 100, and choice D is off by a factor of 1000.

Question 3 of 5

How many milligrams (mg) are equal to 1 gram?

Correct Answer: B

Rationale: The correct answer is B: 1,000 mg. There are 1,000 milligrams in 1 gram. This is because the prefix "milli-" represents one thousandth, so 1 gram is equal to 1,000 milligrams. Choice A (100 mg) is incorrect because it represents only a hundredth of a gram. Choice C (1 mg) is incorrect as it is only one thousandth of a gram. Choice D (10,000 mg) is incorrect as it is actually 10 grams, not 1 gram.

Question 4 of 5

Convert 0.07 to a fraction.

Correct Answer: A

Rationale: To convert 0.07 to a fraction, we note that 0.07 = 7/100. The rationale is to move the decimal two places to the right to get the numerator and place it over 100 (10^2) to get the denominator. Option A (7/100) is correct. Option B (1/10) is incorrect because it represents 0.1, not 0.07. Option C (1/20) is incorrect as it represents 0.05. Option D (1/50) is incorrect as it represents 0.02.

Question 5 of 5

Which basic SI conversion is incorrect?

Correct Answer: D

Rationale: The correct answer is D. In the metric system, 1 gram is equal to 1000 milligrams, not 100 milligrams. This is because the prefix "milli-" denotes a factor of 1/1000. Therefore, the conversion should be 1 g = 1000 mg. Choices A, B, and C are correct conversions as they follow the standard metric system prefixes: centi- (1/100), deci- (1/10), and kilo- (1000), respectively.
