To administer the correct dose of amoxicillin, the nurse needs to calculate the volume of suspension that contains the prescribed dose of 500 mg.

Since the available suspension has a concentration of 250 mg per 5 ml, the nurse can calculate the required volume using the formula: (prescribed dose/concentration) x volume of concentration = required volume.

Plugging in the numbers: (500 mg / 250 mg) x 5 ml = 2 x 5 ml = 10 ml.

Therefore, the nurse should administer 10 ml of the amoxicillin suspension to deliver a dose of 500 mg.

A. This is normal.
Guaifenesin is an expectorant medication commonly used to help loosen and thin mucus in the airways, making it easier to cough up. Coughing up phlegm after taking guaifenesin is a typical and expected response to the medication. Therefore, reassuring the client that this is a normal effect of the medication is appropriate.

B. This requires further investigation: Coughing up phlegm after taking guaifenesin is a common and expected outcome, so further investigation is not necessary unless there are other concerning symptoms or indications.

C. This is indicative of an allergic reaction: Coughing up phlegm after taking guaifenesin is not indicative of an allergic reaction. Allergic reactions to guaifenesin are rare and typically present with more severe symptoms such as rash, itching, swelling, or difficulty breathing.

D. This means there is probably more pathology present: Coughing up phlegm after taking guaifenesin does not necessarily indicate the presence of additional pathology. Guaifenesin is intended to help clear mucus from the airways and is commonly used in the treatment of respiratory conditions associated with excess mucus production, such as cough due to cold or bronchitis.
