A nurse is preparing a medication for a client and is converting grams to milligrams. Which of the following actions should the nurse take?

A. Move the decimal point 2 places to the right: To convert grams to milligrams, the decimal is moved 3 places to the right (1 gram = 1000 mg). B. Move the decimal point 3 places to the left. This action would convert milligrams to grams, not the other way around. C. Move the decimal point 3 places to the right. When converting from grams (g) to milligrams (mg), the nurse must recognize that 1 gram = 1,000 milligrams. Grams to milligrams: To convert grams to milligrams, the nurse must multiply by 1,000, which involves moving the decimal point 3 places to the right. D. Move the decimal point 2 places to the left.
