A patient 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 patient's bowel sounds and measure the abdominal girth.

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

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

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