Nursing Metric Conversions Questions

Question 1 of 5

What is 0.025 mg converted to micrograms?

Correct Answer: A

Rationale: To convert mg to mcg, you multiply by 1000 since 1 mg = 1000 mcg. Therefore, 0.025 mg * 1000 = 25 mcg, which is choice A. Choice B is incorrect as it incorrectly multiplies by 10 instead of 1000. Choice C is incorrect as it incorrectly divides by 10. Choice D is incorrect as it incorrectly divides by 100 instead of multiplying by 1000.

Question 2 of 5

How many micrograms (mcg) are equivalent to 0.5 milligrams (mg)?

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.

Question 3 of 5

What is 0.05 mg in mcg?

Correct Answer: A

Rationale: To convert mg to mcg, we multiply by 1000. So, 0.05 mg x 1000 = 50 mcg. Therefore, the correct answer is A: 50 mcg. Choice B (500 mcg) is incorrect as it would be the result if we mistakenly multiplied by 10, not 1000. Choice C (5 mcg) is incorrect as it represents the original value in mcg, not the converted value. Choice D (0.5 mcg) is incorrect as it is the result if we mistakenly divided by 1000 instead of multiplying.

Question 4 of 5

How many milliliters are in 0.5 liters?

Correct Answer: A

Rationale: To convert liters to milliliters, you need to multiply by 1000 since there are 1000 milliliters in 1 liter. Therefore, to find how many milliliters are in 0.5 liters, you would multiply 0.5 by 1000 which equals 500 ml. This makes choice A, 500 ml, the correct answer. Choices B, C, and D are incorrect because they do not correctly convert liters to milliliters. Choice B (50 ml) is 10 times less than the correct answer, choice C (5 ml) is 100 times less, and choice D (0.5 ml) is 1000 times less than the correct answer.

Question 5 of 5

The metric prefix of Tera is abbreviated as T- and has a value of 10^12. What does Tera mean numerically?

Correct Answer: C

Rationale: The metric prefix Tera is abbreviated as T- and represents 10^12, which means 1 trillion. Tera is derived from the Greek word for "monster" or "giant." Therefore, the correct numerical value for Tera is 10^12. Choice A (10^6) is incorrect as it represents the metric prefix "Mega." Choice B (10^9) is incorrect as it represents the metric prefix "Giga." Choice D (10^3) is incorrect as it represents the metric prefix "Kilo."
