A 28-year-old woman is diagnosed with relapsing-remitting multiple sclerosis (RRMS) and is prescribed interferon beta-1a (Avonex). Which statement by the patient indicates a need for further teaching regarding this medication?

Appeared in: RUHS, Jaipur, M.Sc Nursing Entrance Exam-2015

Explanation

Multiple Sclerosis (MS) is a chronic autoimmune disease for which there is currently no cure.
Interferon beta-1a (Avonex) is a disease-modifying therapy (DMT), not a curative treatment.
The goal of DMTs is to inhibit the dysfunctional immune system, which helps to reduce the frequency of relapses and slow the progression of physical disability.
A patient believing the medication will cure their MS demonstrates a fundamental misunderstanding of the disease and its management, requiring immediate clarification and further education from the nurse.

Option A: This statement shows correct understanding. Flu-like symptoms (fever, myalgia, chills) are the most common side effects of interferon therapy. Pre-medicating with an NSAID or acetaminophen is a standard recommendation to manage these symptoms.
Option B: This statement shows correct understanding. Rotating injection sites is a crucial practice for any medication given repeatedly via injection (subcutaneous or intramuscular) to prevent skin breakdown, pain, inflammation, and lipodystrophy.
Option D: This statement shows correct understanding. It correctly identifies the specific administration details for Avonex, which is given as an intramuscular (IM) injection once per week.

Clinical Relevance

Nursing practice connection: Use the key finding related to Patient education for disease-modifying therapy in Multiple Sclerosis (MS) to guide bedside assessment, documentation, and the next nursing action.
A primary nursing role in chronic illness management is patient education. Ensuring patients have realistic expectations about their treatment is critical for adherence, coping, and mental well-being.
Misunderstanding a treatment's goal can lead to non-adherence if the patient becomes discouraged when the 'cure' doesn't happen, potentially leading to disease progression.
What if the patient was prescribed Ocrelizumab (Ocrevus)? The teaching would need to be different. The nurse would explain it's a twice-yearly intravenous infusion, and while it also slows progression, it has different side effects (like infusion reactions) and monitoring requirements.

How to Approach the Question

First, identify the core of the question: it's asking you to spot a patient's misunderstanding about their medication.
This requires you to know the key facts about the disease (MS) and the drug (Interferon beta-1a/Avonex).
Analyze each option by asking, 'Is this statement factually correct and appropriate for this medication and disease?'
Option 1: Are flu-like symptoms a side effect of interferons? Yes. Is using an NSAID a correct management strategy? Yes. So, this is correct understanding.
Option 2: Is rotating injection sites a standard nursing practice? Yes. So, this is correct understanding.
Option 3: Is there a cure for MS? No. This statement contradicts a fundamental fact about the disease. This is likely the answer.
