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
What is 0.03 as a fraction?
Correct Answer: A
Rationale: To convert 0.03 to a fraction, we can write it as 3/100 since 0.03 can be expressed as 3 hundredths. Therefore, the correct answer is A: 3/100. Option B (1/30) is incorrect because it represents 0.033, not 0.03. Option C (1/3) is incorrect as it represents 0.3, not 0.03. Option D (1/10) is incorrect as it represents 0.1, not 0.03.
Question 3 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."
Question 4 of 5
What is 0.5 liters converted to milliliters?
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.
Question 5 of 5
What is 0.5 liters expressed in milliliters?
Correct Answer: B
Rationale: The correct answer is B: 500 ml. To convert liters to milliliters, you need to remember that 1 liter is equal to 1000 milliliters. Therefore, 0.5 liters is equal to 0.5 * 1000 = 500 milliliters. Option A (50 ml) is incorrect as it represents 0.05 liters, Option C (5 ml) is incorrect as it represents 0.005 liters, and Option D (0.5 ml) is incorrect as it represents 0.0005 liters.
