Nursing Metric Conversion

1. How many meters are equivalent to 3 kilometers?

Correct answer: B

Rationale: To convert from kilometers to meters, you need to multiply by 1,000 since there are 1,000 meters in a kilometer. Therefore, 3 kilometers is equal to 3,000 meters. Choices A, C, and D are incorrect because they do not correctly convert kilometers to meters.

2. Convert 345 centimeters to kilometers (km).

Correct answer: B

Rationale: To convert centimeters to kilometers, you need to divide by 100,000 since there are 100,000 centimeters in a kilometer. Therefore, 345 cm รท 100,000 = 0.00345 km. The correct answer is 0.0345 km, which is obtained by accurately dividing 345 by 100,000. Choices A, C, and D are incorrect because they do not correctly apply the conversion factor and result in inaccurate values for kilometers.

3. How many milliliters are in a tablespoon?

Correct answer: B

Rationale: The correct answer is B: 15 ml. One tablespoon is equivalent to 15 milliliters. The conversion factor for tablespoons to milliliters is 1 tablespoon = 15 milliliters. Choice A (10 ml) is incorrect because it is not the standard conversion for a tablespoon. Choice C (5 ml) is incorrect as it is too low for a tablespoon. Choice D (20 ml) is incorrect as it is too high for a tablespoon. Therefore, the correct conversion is 15 milliliters for one tablespoon.

4. Convert 0.07 to a fraction.

Correct answer: A

Rationale: To convert 0.07 to a fraction, we note that 0.07 is equivalent to 7/100. This is because 0.07 can be read as 7 hundredths. Thus, the correct fraction form is 7/100. Choices B, C, and D are incorrect. Choice B, 1/10, is the fraction equivalent to 0.1, not 0.07. Choice C, 1/20, and Choice D, 1/50, are also incorrect as they do not represent the value of 0.07 when converted to a fraction.

5. Convert 100 grams to kilograms.

Correct answer: A

Rationale: To convert grams to kilograms, you need to divide by 1000 since there are 1000 grams in a kilogram. So, 100 grams divided by 1000 equals 0.1 kilograms, making choice A the correct answer. Choices B, C, and D are incorrect because they do not involve the correct conversion factor or calculation. Choice B of 1 kg is the equivalent of 1000 grams, which is 10 times the given value of 100 grams, making it too large. Choice C of 10 kg is 100 times the given value, and choice D of 0.01 kg is 10 times smaller than the correct conversion.
