Metric Conversions for Nursing
1. What is the value of one femtometer (fm) in meters?
- A. 10^-15 meters
- B. 10^-9 meters
- C. 10^-12 meters
- D. 10^-18 meters
Correct answer: A
Rationale: A femtometer is equivalent to 10^-15 meters. The prefix 'femto-' signifies a factor of one quadrillionth (10^-15), making choice A the correct answer. Choice B (10^-9 meters) represents a nanometer, not a femtometer. Choice C (10^-12 meters) corresponds to a picometer, not a femtometer. Choice D (10^-18 meters) is even smaller than a femtometer and refers to an attometer, not a femtometer.
2. What is the base unit for liquid volume in the metric system?
- A. Milliliters
- B. Liters
- C. Gallons
- D. Liters
Correct answer: B
Rationale: The correct answer is B: Liters. In the metric system, liters are the base unit for liquid volume. Milliliters, though a metric unit, are a smaller unit of volume and not the base unit. Gallons, on the other hand, are part of the imperial system and not a metric unit for volume. Option D is a duplicate of option B, making it incorrect.
3. How many millimeters (mm) are in 3.45 meters?
- A. 345 mm
- B. 3,450 mm
- C. 345,000 mm
- D. 3.45 mm
Correct answer: B
Rationale: To convert meters to millimeters, you need to multiply by 1,000 because there are 1,000 millimeters in a meter. Therefore, 3.45 meters × 1,000 = 3,450 millimeters. Choices A, C, and D are incorrect because they do not reflect the correct conversion factor from meters to millimeters.
4. How many ounces are in 2 quarts?
- A. 8 ounces
- B. 32 ounces
- C. 16 ounces
- D. 64 ounces
Correct answer: C
Rationale: To convert quarts to ounces, you need to know that 1 quart is equal to 32 ounces. Therefore, 2 quarts would be 2 x 32 = 64 ounces. The correct answer is not 16 ounces as stated in the original rationale. The correct answer is 64 ounces, which corresponds to 2 quarts. As a result, 'C: 16 ounces' is incorrect. Options A, B, and D are also incorrect as they do not reflect the accurate conversion from quarts to ounces.
5. What is 0.4 grams in milligrams?
- A. 400 mg
- B. 40 mg
- C. 4 mg
- D. 4000 mg
Correct answer: A
Rationale: To convert grams to milligrams, you need to multiply by 1000 as there are 1000 milligrams in one gram. Therefore, 0.4 grams x 1000 = 400 mg. Choice A, 400 mg, is the correct answer. Choices B, C, and D are incorrect because they do not correctly apply the conversion factor of 1000 to convert grams to milligrams.
