Nursing Metric Conversions

Correct Answer: B

Rationale: To convert liters to milliliters, you need to multiply by 1000 since 1 liter = 1000 milliliters. Therefore, 1.5 liters x 1000 = 1500 milliliters. So, the correct answer is B: 1,500 mL. A is incorrect as it is 10 times less than the correct answer. C is incorrect as it is 10 times less than the correct answer. D is incorrect as it is 100 times more than the correct answer.

Correct Answer: C

Rationale: To convert from quarts to ounces, you need to know that 1 quart is equal to 32 ounces. Therefore, 2 quarts would be 2 * 32 = 64 ounces. The correct answer is C (16 ounces) because it is the only option that correctly states the conversion from quarts to ounces. Option A (8 ounces) is incorrect as it is half of the correct answer. Option B (32 ounces) is incorrect as it represents the amount in 1 quart, not 2 quarts. Option D (64 ounces) is incorrect as it corresponds to the total number of ounces in 2 quarts, not the conversion from quarts to ounces.

Correct Answer: D

Rationale: To convert mg to mcg, we need to multiply by 1000 since 1 mg = 1000 mcg. So, 0.075 mg x 1000 = 75 mcg. Therefore, the correct answer is D: 750 mcg. The other choices are incorrect because they do not correctly convert milligrams to micrograms. A, B, and C are not the correct conversion of 0.075 mg to mcg.

Correct Answer: A

Rationale: The correct formula to convert Celsius to Fahrenheit is A: (C * 9/5) + 32. To convert Celsius to Fahrenheit, you first multiply the Celsius temperature by 9/5 to get the equivalent in Fahrenheit scale, then add 32 to adjust for the offset between the two scales. This formula correctly accounts for both the scaling factor and the offset. Choices B, C, and D have incorrect scaling factors or offsets, leading to inaccurate conversions. B uses the incorrect scaling factor, C and D incorrectly subtract 32 instead of adding it.

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."
