Metric Conversions for TEAS 7 - Nurselytic

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, 0.09 liters x 1,000 = 90 milliliters.
Choice A, 0.09 ml, is incorrect as it represents the original volume in milliliters.

Choices C and D, 900 ml and 9 ml, are incorrect as they miscalculate the conversion from liters to milliliters.

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.

Correct Answer: A

Rationale: The correct answer is A: 9.
To find the result of multiplying 0.15 by 60, you simply multiply the two numbers together. 0.15 * 60 = 9. This calculation involves basic multiplication.

Choices B, C, and D are incorrect as they do not reflect the correct product of 0.15 and 60. Understanding how to multiply decimals and whole numbers is essential in various real-life scenarios such as calculating percentages or adjusting measurements.

Correct Answer: D

Rationale:
To convert milligrams to micrograms, you need to multiply by 1000 since there are 1000 micrograms in a milligram.
Therefore, to convert 0.075 mg to mcg, you would multiply 0.075 by 1000, which equals 75. Thus, the correct conversion is 750 mcg.
Choice A, 75 mcg, is incorrect as it's the result if you mistakenly multiply by 10 instead of 1000.
Choice B, 7.5 mcg, is incorrect as it's the result if you divide by 10 instead of multiplying by 1000.
Choice C, 0.75 mcg, is incorrect as it's the result if you divide by 100 instead of multiplying by 1000.

Correct Answer: B

Rationale: The correct answer is B: 2.54 cm. One inch is equivalent to 2.54 centimeters in the metric system. This conversion factor is commonly used in converting measurements between the imperial and metric systems.
Choice A (1.54 cm),
Choice C (3.54 cm), and
Choice D (4.54 cm) are incorrect conversions and do not represent the accurate metric equivalent of 1 inch.
