Nursing Metric Conversion

Correct Answer: B

Rationale: The correct answer is B: 2 pints in one quart. A quart is equivalent to 2 pints. This is because there are 2 pints in a quart by definition. To convert pints to quarts, you divide the number of pints by 2. Therefore, the correct answer is 2 pints. Choices A, C, and D are incorrect because they do not align with the conversion factor of 2 pints in one quart. Answer A is too low, C is too high, and D is also too high based on the conversion factor.

Correct Answer: B

Rationale: To convert kilograms to grams, you need to multiply by 1000 since there are 1000 grams in 1 kilogram. Therefore, 35.40 kg x 1000 = 35,400 g (Choice B). This is the correct answer because it correctly applies the conversion factor. Choices A, C, and D are incorrect as they do not correctly convert kilograms to grams. Choice A is too small, Choice C is missing a zero, and Choice D incorrectly divides instead of multiplies.

Correct Answer: A

Rationale: To convert grams to milligrams, you need to multiply by 1000 since there are 1000 milligrams in a gram. So, 0.04 grams * 1000 = 40 milligrams. Therefore, the correct answer is A: 40 mg. Incorrect choices: B: 4 mg - This is incorrect because it does not account for the conversion factor of 1000. C: 400 mg - This is incorrect as it is a result of multiplying by 10 instead of 1000. D: 0.4 mg - This is incorrect as it is the result of dividing by 10 instead of multiplying by 1000.

Correct Answer: B

Rationale: The correct answer is B: volume. Volume refers to the amount of space an object occupies in three dimensions. It is calculated by multiplying the length, width, and height of an object. Mass (A) is the amount of matter in an object, density (C) is the mass per unit volume, and area (D) is the measurement of the surface of an object in two dimensions. Therefore, volume is the most appropriate term for describing the amount of space an object occupies.

Correct Answer: A

Rationale: To convert milliliters to liters, you need to divide by 1000 since there are 1000 milliliters in 1 liter. Therefore, 1500 milliliters divided by 1000 equals 1.5 liters. Choice A (1.5 liters) is correct because it accurately represents the conversion. Choices B, C, and D are incorrect because they do not follow the correct conversion factor of dividing by 1000. Choice B (0.15 liters) is one decimal place off, choice C (15 liters) is an order of magnitude too high, and choice D (0.015 liters) is two decimal places off.
