Metric Conversions for TEAS 7 - Nurselytic

Correct Answer: B

Rationale:
To convert 0.1 liter to milliliters, you need to multiply by 1000 because there are 1000 milliliters in a liter.
Therefore, 0.1 liter converts to 100 milliliters.
Choice A (10 ml) is incorrect as it represents 0.01 liters, not 0.1 liters.
Choice C (1000 ml) is incorrect as it represents 1 liter, not 0.1 liters.
Choice D (1 ml) is incorrect as it is too small a quantity for 0.1 liters.

Correct Answer: A

Rationale:
To convert milligrams (mg) to micrograms (mcg), you need to multiply by 1000 since 1 mg is equal to 1000 mcg.
Therefore, 0.3 mg x 1000 = 300 mcg. This conversion is crucial in healthcare to ensure accurate medication dosages.
Choice B (30 mcg) is incorrect as it represents the conversion of 0.03 mg to mcg.
Choice C (3000 mcg) is incorrect as it is the result of multiplying 0.3 mg by 10 instead of 1000.
Choice D (3 mcg) is incorrect as it is the result of not multiplying by 1000 to convert milligrams to micrograms.

Correct Answer: B

Rationale:
To convert liters to milliliters, you need to multiply by 1000 since there are 1000 milliliters in 1 liter.
Therefore, 0.5 liters x 1000 = 500 milliliters, making choice B the correct answer.

Choices A, C, and D are incorrect because they do not correctly convert liters to milliliters.

Correct Answer: B

Rationale:
To convert meters to kilometers, the conversion factor is 1 kilometer = 1,000 meters.
Therefore, to find how many kilometers are in 1,000 meters, you divide 1,000 by 1,000, which equals 1 kilometer.
Choice A (0.1 km),
Choice C (10 km), and
Choice D (0.01 km) are incorrect because they do not correctly represent the conversion of 1,000 meters to kilometers.

Correct Answer: B

Rationale:
To convert milligrams to grams, you need to divide by 1,000 because there are 1,000 milligrams in a gram.
Therefore, 35,400 mg · 1,000 = 35.4 grams.
Choice A is incorrect because it does not account for the conversion from milligrams to grams.
Choice C is incorrect as it incorrectly drops a zero, leading to an inaccurate conversion.
Choice D is incorrect as it incorrectly multiplies instead of dividing, resulting in a significantly larger value than the correct answer.
