Nursing Metric Conversion
1. What is 0.04 grams converted to milligrams?
- A. 40 mg
- B. 4 mg
- C. 400 mg
- D. 0.4 mg
Correct answer: A
Rationale: To convert grams to milligrams, you need to multiply by 1000, not 10000. Therefore, to convert 0.04 grams to milligrams, you multiply 0.04 by 1000, which equals 40 mg. Choice A (40 mg) is the correct answer. Choice B (4 mg) is incorrect as it represents converting 0.004 grams to milligrams. Choice C (400 mg) is incorrect as it is 10 times the correct conversion. Choice D (0.4 mg) is incorrect as it is 10 times smaller than the correct conversion.
2. What is 0.5 L converted to mL?
- A. 500 mL
- B. 50 mL
- C. 5 mL
- D. 0.5 mL
Correct answer: A
Rationale: To convert liters to milliliters, you need to multiply by 1000 since 1 liter is equal to 1000 milliliters. Therefore, 0.5 liters multiplied by 1000 equals 500 milliliters. Choice A, 500 mL, is the correct answer. Choice B, 50 mL, is incorrect as it represents converting 0.05 liters to milliliters. Choice C, 5 mL, is incorrect as it represents converting 0.005 liters to milliliters. Choice D, 0.5 mL, is incorrect as it represents the original amount in milliliters, not the conversion of liters to milliliters.
3. How many pints are in one quart?
- A. 1 pint
- B. 2 pints
- C. 3 pints
- D. 4 pints
Correct answer: B
Rationale: The correct answer is B: 2 pints. There are 2 pints in one quart. A quart is equivalent to 2 pints, so each quart contains 2 pints. Choice A, 1 pint, is incorrect because a quart consists of more than 1 pint. Choice C, 3 pints, and Choice D, 4 pints, are also incorrect as they do not accurately represent the conversion of quarts to pints.
4. What is the equivalent of 255.0 pounds in kilograms (1 kg = 2.205 lbs)?
- A. 115.7 kg
- B. 126.0 kg
- C. 115.8 kg
- D. 115.6 kg
Correct answer: D
Rationale: To convert pounds to kilograms, you need to divide the weight in pounds by 2.205 (1 kg = 2.205 lbs). Therefore, 255.0 pounds divided by 2.205 equals 115.6 kilograms. This results in choice D being the correct answer. Choices A, B, and C are incorrect as they do not reflect the accurate conversion calculation from pounds to kilograms.
5. How many feet are in one mile?
- A. 5000 feet
- B. 5280 feet
- C. 5300 feet
- D. 5500 feet
Correct answer: B
Rationale: The correct answer is B: 5280 feet. One mile is equivalent to 5280 feet. This is a standard conversion that is widely known. Choice A (5000 feet) is incorrect as it is not the exact conversion of a mile. Choice C (5300 feet) and choice D (5500 feet) are also incorrect as they do not represent the accurate conversion from miles to feet.
