Nursing Metric Conversions

1. How many milliliters are in 1.5 liters?

Correct answer: B

Rationale: To convert liters to milliliters, you need to multiply by 1,000 since there are 1,000 milliliters in a liter. Therefore, 1.5 liters x 1,000 = 1,500 milliliters. Choice A, 15 mL, is incorrect as it represents the conversion of 0.015 liters. Choice C, 150 mL, is incorrect as it represents the conversion of 0.15 liters. Choice D, 150,000 mL, is incorrect as it represents the conversion of 150 liters.

2. How many ounces is equal to 1 gram?

Correct answer: B

Rationale: To convert grams to ounces, you need to multiply the weight in grams by 0.035 to get the equivalent weight in ounces. Therefore, 1 gram is equal to 0.035 ounces. Choices A, C, and D are incorrect conversions and do not accurately represent the conversion factor from grams to ounces.

3. How many milliliters are in 2 liters?

Correct answer: A

Rationale: There are 1000 milliliters in 1 liter, so 2 liters equal 2000 milliliters. The conversion is based on the fact that the prefix 'milli-' means one-thousandth. Therefore, the correct answer is 2000 mL. Choice B, 20,000 mL, is incorrect as it multiplies 2 liters by 10. Choice C, 200 mL, is incorrect as it divides 2 liters by 10. Choice D, 2 mL, is incorrect as it incorrectly assumes that 2 liters is equal to 2 milliliters.

4. How many millimeters are in 1 centimeter?

Correct answer: B

Rationale: The correct answer is B: '10 mm'. There are 10 millimeters in 1 centimeter. To convert centimeters to millimeters, you multiply by 10 because 1 centimeter is equivalent to 10 millimeters. Choice A '1 mm' is incorrect as it represents the size of 1 millimeter, not the conversion from centimeters to millimeters. Choice C '100 mm' is incorrect as it is the equivalent of 1 meter, not 1 centimeter. Choice D '1,000 mm' is incorrect as it is the equivalent of 1 meter, not 1 centimeter.

5. Which metric prefix represents 10^-2?

Correct answer: A

Rationale: The metric prefix 'centi-' signifies 10^-2, denoting one-hundredth of a unit. For instance, 1 centimeter equals 0.01 of the base unit. Choice B, 'milli,' represents 10^-3, 'nano' in Choice C represents 10^-9, and 'deci' in Choice D stands for 10^-1. Therefore, the correct answer is 'centi.'
