Metric Conversions for Nursing

Correct Answer: B

Rationale: To convert millimeters to meters, we divide by 1000 since there are 1000 millimeters in a meter. Therefore, 3.54 mm in meters is 3.54/1000 = 0.00354 meters. Choice B is correct as it correctly converts 3.54 mm to meters. Choices A, C, and D are incorrect because they do not apply the correct conversion factor. Choice A incorrectly moves the decimal point two places to the left instead of three. Choice C incorrectly multiplies by 10 instead of dividing by 1000. Choice D incorrectly moves the decimal point one place to the left instead of three.

Correct Answer: D

Rationale: To convert mg to mcg, you multiply by 1000. Therefore, 0.075 mg x 1000 = 75 mcg. Correct Answer: D. Option A is incorrect as it is the same unit, not converted. Option B is 10 times the correct answer. Option C is 100 times the correct answer.

Correct Answer: A

Rationale: The correct answer is A: 100 g. To convert kilograms to grams, you need to multiply by 1000 since there are 1000 grams in a kilogram. Therefore, 0.1 kg x 1000 = 100 g. Choice B (10 g) is incorrect as it represents 0.01 kg. Choice C (1 g) is incorrect as it represents 0.001 kg. Choice D (0.1 g) is incorrect as it is the same value as the original measurement in kilograms.

Correct Answer: B

Rationale: To convert pounds to ounces, you need to know that 1 pound is equal to 16 ounces. So, to convert 0.29 pounds to ounces, you multiply 0.29 by 16. This gives you 4.64 ounces, which is the correct answer (B). Choices A, C, and D are incorrect because they do not correctly apply the conversion factor of 16 ounces per pound.

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.
