A client who is newly diagnosed with erosive esophagitis secondary to gastroesophageal reflux disease (GERD) reports to the home health nurse that there has been only a minimal reduction in symptoms after taking lansoprazole PO for one full week. Which action should the nurse take?

Auscultate the client's bowel sounds and measure the abdominal girth.

Confirm that the client is taking the medication one hour after meals.

Notify the healthcare provider that the client may need a change in dosage.

Advise the client that healing typically takes several weeks to occur.
