An ulcer caused by H. pylori can be successfully treated with which classification of drugs?

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.

A) Take as needed for pain relief.
Sucralfate is not used as an as-needed medication for pain relief. It is a gastroprotective medication that is typically taken regularly as prescribed, regardless of whether the client is experiencing pain.

B) Take the medication 1 hr before meals.
Sucralfate is a medication commonly used to treat peptic ulcer disease by forming a protective barrier over the ulcer, promoting healing and symptom relief. It should be taken on an empty stomach, at least 1 hour before meals, and at bedtime to maximize its effectiveness. Taking sucralfate before meals ensures that the medication can coat the ulcer and provide protection against gastric acid during digestion.

C) Store the medication in the refrigerator.
Sucralfate does not need to be stored in the refrigerator. It should be stored at room temperature away from moisture and heat, according to the manufacturer's instructions.

D) Take the medication with an antacid.
Sucralfate should not be taken with antacids because antacids can interfere with its effectiveness. Antacids can decrease the absorption of sucralfate, so it is important to separate the administration of sucralfate from antacids by at least 30 minutes to 1 hour.
