Nursing Metric Conversion

Correct Answer: B

Rationale: To convert millimeters to meters, you divide by 1000 since there are 1000 millimeters in a meter. So, 354,000 mm ÷ 1000 = 354 m. Choice B is correct as it correctly converts millimeters to meters. Choice A is incorrect as it doesn't account for the conversion. Choice C is incorrect as it converts to kilometers instead of meters. Choice D is incorrect as it is a miscalculation of the conversion.

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: B

Rationale: The correct answer is B: 15 ml. A standard tablespoon is equivalent to 15 ml. This is a standard measurement in culinary and pharmaceutical fields. A tablespoon is commonly used for measuring liquid ingredients and medications. Choice A (10 ml) and Choice D (20 ml) are incorrect as they do not correspond to the standard measurement of a tablespoon. Choice C (5 ml) is also incorrect as it is too low to be the equivalent of a tablespoon. Therefore, B is the correct answer.

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.
