Metric Conversions for Nursing Questions
Question 1 of 5
What is the equivalent of 500 milliliters in liters?
Correct Answer: B
Rationale: To convert milliliters to liters, we need to divide by 1000 since 1 liter is equal to 1000 milliliters. So, 500 milliliters divided by 1000 equals 0.5 liters, making choice B the correct answer. Choice A (0.05 liters) is incorrect as it is one decimal place off. Choice C (5 liters) and choice D (50 liters) are both significantly higher values and do not align with the conversion factor from milliliters to liters.
Question 2 of 5
What does the prefix 'Tera' refer to?
Correct Answer: A
Rationale: The prefix 'Tera' corresponds to the value of 10^12. This can be understood by knowing that the International System of Units (SI) prefixes are based on powers of 10. 'Tera' comes after 'Giga' (10^9) and before 'Peta' (10^15). Therefore, the correct choice is A. Summary of other choices: B: Incorrect because 'Giga' represents 10^9. C: Incorrect as 'Peta' represents 10^15, a higher value. D: Incorrect because 'Mega' represents 10^6, a lower value than 'Tera'.
Question 3 of 5
What does 'cm' stand for in the metric system?
Correct Answer: A
Rationale: The correct answer is A: centimeter. 'cm' stands for centimeter in the metric system. 'Centi' is a prefix that means one hundredth, so centimeter represents one hundredth of a meter. Choice B, cubic meter, is incorrect because 'cm' does not refer to volume. Choice C, cord, is a unit of measurement for stacked firewood and is not related to 'cm.' Choice D, centi, is a prefix used to indicate one hundredth, but it is not the complete unit itself.
Question 4 of 5
Convert 0.07 to a fraction.
Correct Answer: A
Rationale: To convert 0.07 to a fraction, we note that 0.07 = 7/100. The rationale is to move the decimal two places to the right to get the numerator and place it over 100 (10^2) to get the denominator. Option A (7/100) is correct. Option B (1/10) is incorrect because it represents 0.1, not 0.07. Option C (1/20) is incorrect as it represents 0.05. Option D (1/50) is incorrect as it represents 0.02.
Question 5 of 5
Convert 0.0345 kilograms to grams (g).
Correct Answer: B
Rationale: To convert from kilograms to grams, you multiply the value in kilograms by 1000 since there are 1000 grams in one kilogram. Therefore, 0.0345 kg * 1000 = 34.5 grams. Choice B (34.5 grams) is correct. Choices A, C, and D are incorrect because they do not correctly convert kilograms to grams. Choice A is off by a factor of 10, choice C is off by a factor of 100, and choice D is off by a factor of 1000.
