Final answer:
To administer the correct dose of mucomyst 1.2g from a 20% solution, you would give 6 mL per dose.
Step-by-step explanation:
The order is for mucomyst 1.2g (acetylcysteine) to be taken orally four times a day (qid), with the first dose to be given immediately. Considering that the available mucomyst is a 20% solution, we need to calculate the volume of the solution to provide the required 1.2g dose.
To find the volume needed for a 1.2g dose of a 20% solution, we can set up the following equation: 1.2g / (0.2g/mL) = x mL. Solving for x gives us 6 mL. Therefore, you will administer 6 mL per dose of the 20% mucomyst solution.
