Final answer:
To determine the volume of medication to administer based on the order and stock concentration, we calculate the proportion and find that 1.67 mL is the required volume.
Step-by-step explanation:
The subject of this question is mathematics, specifically medication dosage calculation, which involves using the provided stock concentration of medicine to determine the correct volume to administer a prescribed dose. To solve the problem: Order: ABC 750 mg. Stock: ABC 1.8 g/4 mL. How many mL(s) will you give? we need to convert the order to grams since the stock concentration is given in grams. Therefore, 750 mg is equal to 0.75 g. Then, using the given stock concentration, 1.8 g of ABC is contained in 4 mL, so we can set up a proportion to find the required volume for 0.75 g. The proportion is (0.75 g / 1.8 g) = (V / 4 mL), where V is the volume needed for 0.75 g of ABC. Solving for V gives us V = (0.75 g * 4 mL) / 1.8 g, which equals 1.67 mL when rounded to two significant figures.
