Metric Conversions for Nursing Questions
Question 1 of 5
What is 0.4 divided by 40?
Correct Answer: B
Rationale: To divide 0.4 by 40, we can rewrite 0.4 as 4/10. Then, we divide 4 by 10 to get 0.1. So, 0.4 divided by 40 equals 0.1. Simplifying 0.1 as a fraction gives 1/10. To further simplify, we can divide both the numerator and denominator by 10 to get 1/1000, which is choice B. Choices A, C, and D are incorrect as they do not accurately represent the division of 0.4 by 40.
Question 2 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 3 of 5
How many milliliters are in 1 ounce?
Correct Answer: B
Rationale: To convert ounces to milliliters, we need to know that 1 ounce is approximately equal to 29.57 milliliters. Therefore, the closest option to this conversion is B: 30 ml. Choices A, C, and D are not correct as they do not match the accurate conversion rate. A (20 ml) is too low, C (40 ml) is too high, and D (50 ml) is also too high. Therefore, the correct answer is B (30 ml) as it is the closest approximation to the actual conversion rate of 1 ounce to milliliters.
Question 4 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.
Question 5 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.
