Metric Conversions for Nursing

1. What is 0.04 g in mg?

Correct answer: A

Rationale: To convert grams to milligrams, you multiply by 1000 since there are 1000 milligrams in a gram. Therefore, to convert 0.04 grams to milligrams, you would do 0.04 * 1000 = 40 mg. Choice A, '40 mg,' is the correct answer. Choices B, C, and D are incorrect because they do not correctly convert grams to milligrams. Choice B, '400 mg,' is incorrect because it mistakenly multiplies by 10 instead of 1000. Choice C, '4 mg,' is incorrect because it does not account for the correct conversion factor. Choice D, '0.4 mg,' is incorrect because it underestimates the conversion by a factor of 10.

2. What unit is used to measure density in the metric system?

Correct answer: A

Rationale: Density is measured in grams per cubic meter (g/m³) in the metric system. This unit represents the amount of mass (in grams) per unit volume (cubic meter). Choice B, grams per liter (g/L), is incorrect as density is not typically measured in liters. Choice C, grams per cubic centimeter (g/cm³), is a common unit for density but not the standard SI unit. Choice D, grams per square meter (g/m²), is a unit for surface density, not volumetric density. Therefore, the correct unit for measuring density in the metric system is grams per cubic meter (g/m³).

3. How many millimeters are in 5 centimeters?

Correct answer: B

Rationale: To convert centimeters to millimeters, you multiply by 10 since there are 10 millimeters in a centimeter. Therefore, 5 centimeters x 10 = 50 millimeters, making choice A the correct answer. Choice C, '5 mm,' is incorrect as it represents the original quantity in millimeters. Choice D, '500 cm,' is incorrect as it converts the centimeters to centimeters instead of millimeters.

4. How many pints are in one quart?

Correct answer: B

Rationale: The correct answer is B: 2 pints. There are 2 pints in one quart. A quart is equivalent to 2 pints, so each quart contains 2 pints. Choice A, 1 pint, is incorrect because a quart consists of more than 1 pint. Choice C, 3 pints, and Choice D, 4 pints, are also incorrect as they do not accurately represent the conversion of quarts to pints.

5. What is 0.4 divided by 40?

Correct answer: B

Rationale: The calculation of 0.4 divided by 40 results in 0.01, which can be expressed as 1/100. This fraction is the correct representation of the division of 0.4 by 40. Choice A, 1/100, is the correct answer as it accurately reflects the division. Choices C and D, 1/400 and 1/40000 respectively, do not correctly represent the division operation performed on 0.4 and 40, leading to incorrect results and are therefore not the correct answers.
