Nursing Metric Conversions

Correct Answer: B

Rationale: To convert liters to milliliters, you need to multiply by 1000 because there are 1000 milliliters in 1 liter. So, 3,540 liters x 1000 = 3,540,000 mL. Therefore, choice B (3,540,000 mL) is the correct answer. Choice A (354,000 mL) is incorrect because it doesn't account for the conversion factor. Choice C (35,400 mL) and choice D (35,400,000 mL) are also incorrect as they do not correctly apply the conversion factor.

Correct Answer: B

Rationale: To convert liters to milliliters, you need to multiply by 1000 since 1 liter equals 1000 milliliters. So, 0.2 liters x 1000 = 200 milliliters, making choice B the correct answer. Choice A is incorrect as it represents 0.02 liters. Choice C is incorrect as it represents 0.002 liters. Choice D is incorrect as it represents 2 liters, not 0.2 liters.

Correct Answer: B

Rationale: To convert meters to centimeters, we know that 1 meter is equal to 100 centimeters. Therefore, to find how many centimeters are in 0.25 meters, we multiply 0.25 by 100, giving us 25 centimeters. Explanation for incorrect choices: A: 2.5 cm - Incorrect because 0.25 meters is equivalent to 25 cm. C: 250 cm - Incorrect because multiplying 0.25 by 100 gives 25 cm, not 250 cm. D: 0.25 cm - Incorrect because this doesn't follow the conversion from meters to centimeters.

Correct Answer: A

Rationale: The SI prefix "micro" represents 10^-6 and "milli" represents 10^-3. To understand this, recall that "micro" comes from the Greek word for small, and it signifies a factor of 1/1,000,000 (10^-6). On the other hand, "milli" indicates a factor of 1/1,000 (10^-3). Therefore, the correct answer is A: 10^-6 and 10^-3. Choice B (10^-9 and 10^-6) is incorrect because it confuses the values of micro and nano prefixes. Choice C (10^-12 and 10^-9) is incorrect as it mixes up the prefixes for pico and nano. Choice D (10^-15 and 10^-12) is incorrect as it refers to femto and pico prefixes, respectively.

Correct Answer: A

Rationale: To convert 0.26 to a fraction, we can write it as 26/100 since 0.26 is equivalent to 26 hundredths. To simplify this fraction, we divide the numerator and denominator by their greatest common divisor, which is 2. Therefore, 26/100 simplifies to 13/50. This is the correct answer (A) in simplest form. Choice B (26/100) is the initial form of 0.26 but not in simplest form as it can be further simplified to 13/50. Choice C (26/1000) is incorrect as the decimal 0.26 is equivalent to 26/100, not 26/1000. Choice D (1/4) is not equivalent to 0.26.
