Metric Conversions for Nursing Questions

Question 1 of 5

What is 0.2 liters when converted to milliliters?

Correct Answer: B

Rationale: The correct answer is B: 200 ml. To convert liters to milliliters, you need to multiply by 1000 since 1 liter equals 1000 milliliters. Therefore, 0.2 liters x 1000 = 200 ml. A) 20 ml is incorrect as it is the result of incorrectly converting 0.02 liters. C) 2 ml is incorrect as it is the result of incorrectly converting 0.002 liters. D) 2000 ml is incorrect as it is the result of incorrectly converting 2 liters.

Question 2 of 5

How many micrograms are in 0.15 mg?

Correct Answer: A

Rationale: To convert milligrams to micrograms, you need to multiply by 1000. So, 0.15 mg x 1000 = 150 mcg. This is why choice A (150 mcg) is correct. Choice B (15 mcg) is incorrect as it doesn't account for the conversion factor. Choice C (1.5 mcg) is incorrect as it is off by a factor of 10. Choice D (1500 mcg) is incorrect as it overestimates the conversion.

Question 3 of 5

Convert 0.29 pounds to ounces.

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.

Question 4 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.

Question 5 of 5

What does the prefix 'milli' mean?

Correct Answer: B

Rationale: The prefix 'milli' denotes 1/1000, which is equivalent to 0.001. This means that any unit following 'milli' is divided by 1000. Therefore, the correct answer is B, 0.001. Choice A (0.01) is incorrect as it represents the prefix 'centi,' which means 1/100. Choice C (0.0001) is incorrect as it represents the prefix 'micro,' which means 1/1,000,000. Choice D (0.00001) is incorrect as it represents the prefix 'nano,' which means 1/1,000,000,000.
