Convert 5 kilograms to grams.

Correct Answer: C

Rationale: In nursing, understanding metric conversion is crucial for accurate medication administration and patient care. When converting kilograms to grams, it is important to remember that there are 1000 grams in 1 kilogram. Therefore, to convert 5 kilograms to grams, we multiply 5 by 1000, which equals 5,000 grams. Option A (50 grams) is incorrect because it does not account for the correct conversion factor. Option B (500 grams) is also incorrect as it represents the weight of half a kilogram. Option D (50,000 grams) is incorrect as it incorrectly multiplies 5 by 10,000 instead of 1,000. Educationally, this question reinforces the importance of mastering basic metric conversions in nursing practice. Nurses must be able to convert between different units accurately to ensure proper dosing and patient safety. Understanding these conversions also helps in interpreting lab values and understanding medication orders. Mastery of these fundamental skills is essential for nursing professionals to provide high-quality care.

Correct Answer: B

Rationale: To convert milliliters to liters, you need to divide by 1000 since there are 1000 milliliters in a liter. Therefore, 750 milliliters divided by 1000 equals 0.75 liters. Choice A (7.5 liters) is incorrect as it is off by a factor of 10. Choice C (0.0075 liters) is incorrect as it is off by a factor of 100. Choice D (0.075 liters) is incorrect as it is off by a factor of 10.

Correct Answer: D

Rationale: To convert millimeters to centimeters, you need to divide by 10 because there are 10 millimeters in one centimeter. Therefore, 25 millimeters is equal to 25/10 = 2.5 centimeters, making choice D the correct answer. Choice A (250 cm) is incorrect as it incorrectly multiplies instead of dividing by 10. Choice B (25 cm) is also incorrect as it doesn't convert millimeters to centimeters. Choice C (2.5 mm) is incorrect as it provides the measurement in millimeters rather than centimeters.

Correct Answer: C

Rationale: To convert milliliters to liters, you need to divide by 1,000 since there are 1,000 milliliters in a liter. Therefore, 3,000 milliliters / 1,000 = 3 liters. Choice A '0.3 liters' is incorrect as it represents 300 milliliters, not 3,000. Choice B '30 liters' is incorrect as it is the result of multiplying by 10 instead of dividing by 1,000. Choice D '0.03 liters' is incorrect as it represents 30 milliliters, not 3,000.

Correct Answer: B

Rationale: To convert kilograms to grams, you need to multiply by 1000 since there are 1000 grams in 1 kilogram. Therefore, 0.5 kilograms is equal to 500 grams (0.5 x 1000 = 500). Choice A (50 grams) is incorrect as it is the result of multiplying by 10 instead of 1000. Choice C (5,000 grams) is incorrect as it is the result of adding an extra zero. Choice D (0.5 grams) is incorrect as it represents the original amount in grams, not the converted amount.
