NCLEX question 💡

When caring for patients prescribed sucralfate (Carafate) for peptic ulcer disease (PUD) alongside phenytoin (Dilantin) for seizure control, understanding their interaction is essential. Sucralfate acts by forming a protective barrier on the mucosal lining of the stomach, but it can interfere with the absorption of other medications like phenytoin if taken too closely together. This interaction reduces phenytoin's effectiveness, potentially increasing seizure risk. The recommended nursing intervention is to advise patients to schedule a minimum 2-hour interval between taking these medications. This allows sufficient time for phenytoin absorption before sucralfate is administered, ensuring both drugs work effectively. Patients should not take sucralfate with milk, as it can affect its action, nor should they chew the tablets; swallowing with water is appropriate. Education should also include monitoring for signs of decreased seizure control, emphasizing medication adherence, and encouraging patients to communicate any adverse effects. This type of clinical reasoning improves safety outcomes and is crucial preparation for the NCLEX exam, which frequently tests knowledge of pharmacological interactions and patient teaching strategies. Overall, mastering questions on drug interactions like this one strengthens clinical judgment and helps nursing students and professionals provide safe medication management in practice.
