Nursing Metric Conversions

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. So, the correct answer is B: 500 ml. Choice A (50 ml) is incorrect as it is the result of multiplying by 10 instead of 1000. Choice C (5 ml) is incorrect as it is the result of dividing by 10 instead of multiplying by 1000. Choice D (0.5 ml) is incorrect as it represents the original amount in milliliters instead of the converted value.

Correct Answer: B

Rationale: The correct answer is B: 2000 pounds. There are 2000 pounds in 1 ton because a ton is equal to 2000 pounds. This conversion is based on the fact that 1 ton is equivalent to 2000 pounds in the imperial system of measurement. Therefore, to convert tons to pounds, you simply multiply the number of tons by 2000. Choice A (1000 pounds) is incorrect because it represents half a ton, not a full ton. Choice C (1500 pounds) and Choice D (2500 pounds) are also incorrect as they do not match the actual conversion factor of 2000 pounds in 1 ton.

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.

Correct Answer: B

Rationale: The correct answer is B: 0.3 ml. To convert milliliters to milliliters, we don't need to change the value. Therefore, the equivalent of 0.3 milliliters is still 0.3 ml. A: 0.03 ml - This is incorrect as it represents a value that is one-tenth of the original amount. C: 3 ml - This is incorrect as it represents a value that is 10 times greater than the original amount. D: 30 ml - This is incorrect as it represents a value that is 100 times greater than the original amount.

Correct Answer: A

Rationale: To convert milligrams (mg) to micrograms (mcg), you multiply by 1000 because 1 mg = 1000 mcg. So, to convert 0.5 mg to mcg, you multiply 0.5 by 1000, which equals 500 mcg. Therefore, the correct answer is A: 500 mcg. Choice B (50 mcg) is incorrect as it results from multiplying by 100 instead of 1000. Choice C (5 mcg) is incorrect as it results from multiplying by 10 instead of 1000. Choice D (0.5 mcg) is incorrect as it does not involve any conversion from milligrams to micrograms.
