Answer:
The PN should instruct the client to take 2 teaspoons of the guaifenesin oral solution per dose.
Step-by-step explanation:
The PN should instruct the client to take 2 teaspoons of the guaifenesin oral solution per dose. The explanation for this is that, although the label on the bottle says that the guaifenesin is 100 mg/5 mL, the client's prescription is for 200 mg. Therefore, the client needs to take double the amount in order to get the correct dose of guaifenesin.
