How to Expand Your Knowledge as a Medical Assistant

So, you're a medical assistant. You’ve taken the necessary courses, completed your externship, and, certification in hand, you’re ready to tackle patient care. But reality sets in—you’re surrounded by other MAs and nurses who seem to know everything. Perhaps you’re the only MA among experienced nurses, or maybe your coworkers have years of experience and seem to have answers to every question. This article offers practical ways for you to deepen your knowledge and grow in your career, giving you the confidence and capability to take on even more.

1. Embrace Curiosity: Don’t Be Afraid to Ask Questions

Picture this: you’re checking your inbox and find a note from a provider to call a patient about their lab results and offer advice on improving their levels. You might think, Why does this matter? or What do these numbers even mean? Instead of dismissing these thoughts, see them as an opportunity to ask questions. This curiosity isn’t just beneficial—it’s essential.

Curiosity is key to learning in any clinical role, but it’s especially important for new MAs. Even senior MAs and nurses continue to ask questions because medicine is complex, and every situation is unique. Dr. Mikhail Varshavsky, famously known as “Doctor Mike,” gave a TEDx talk titled The Epidemic of "I Know All" Experts, explaining why admitting when you don’t know something is a strength, not a weakness. He argues that when providers ask questions, they’re demonstrating commitment to evidence-based medicine rather than simply “knowing it all.”

When the moment is right, ask your provider about a patient’s lab results, medication choices, or treatment options. In my experience, providers are often happy to answer these questions, and they appreciate MAs who seek to understand the “why” behind clinical decisions. Plus, they’ll know you’re committed to learning, which can lead to more teaching moments.

2. Don’t Be Afraid to Look It Up: Using Reliable Sources

One of the greatest habits you can develop early on as a medical assistant is to look up information when you’re unsure. Even the most seasoned physicians, nurses, and MAs continue to look things up—it’s part of practicing responsible, evidence-based care. Healthcare is a constantly evolving field, and staying informed is essential to delivering the best care possible. You can’t be expected to know or memorize everything, especially with the vast scope of medical knowledge out there, so use this as an opportunity to learn.

However, not all sources are equal, and it’s crucial to rely on reputable, evidence-based resources. Platforms like UpToDate, Mayo Clinic, Medscape, and CDC guidelines offer reliable, peer-reviewed information that you can trust when researching symptoms, treatments, or medications. These sources are written and reviewed by healthcare professionals, ensuring the information is accurate and up-to-date.

By making a habit of looking things up from reliable sources, you not only ensure that your knowledge is accurate, but you also develop confidence in your ability to respond to questions and explain aspects of care to patients. As an MA, being proactive in learning this way demonstrates your commitment to quality care and helps build trust with your patients and team.

3. Get Involved: Take Initiative to Shadow When Possible

Being proactive with your learning goes beyond asking questions. Whenever possible, take the opportunity to shadow providers or observe more complex cases. Let’s say you roomed a patient with an interesting condition that you haven’t seen before. If another MA can cover your other duties for a few minutes, ask your provider if you can sit in on the visit. Just by listening, you’ll absorb an incredible amount of information about symptoms, diagnostics, and the logic behind treatment decisions.

I’ve had the chance to shadow providers during a variety of procedures, from joint injections and I&Ds to assisting in the OR with an orthopedic surgeon. Each experience was a treasure trove of information. Shadowing doesn’t just teach you the technicalities; it shows you the flow of patient-provider interactions and the nuances of patient care. Over time, you’ll develop a stronger understanding of each procedure and become more confident when discussing care plans with providers and patients alike.

4. Understand the "Why" Behind the Care

Understanding the reasoning behind clinical decisions will deepen your knowledge and make you a more effective MA. Patients often need explanations about why certain treatments are recommended, and understanding these reasons will help you communicate clearly and confidently. When you know the “why” behind a treatment, you’re better equipped to answer patient questions and build trust.

For instance, I once had a conversation with a patient about their use of omeprazole. They were only taking it when symptoms began, wondering why it wasn’t very effective. While most MAs know that omeprazole treats GERD, it helps to understand that it’s a proton pump inhibitor (PPI) designed for preventive use. I explained that omeprazole stops new stomach acid production, meaning it’s most effective when taken daily rather than reactively. The patient was grateful for the information, and I felt more confident in guiding them on proper medication use.

Knowing the science behind medications and treatments will also make you more comfortable in your role. This knowledge doesn’t just come from textbooks or courses but from continuous, real-world learning and engagement with your team.

5. The Personal Payoff: Growing Confidence and Professionalism

The more you ask, learn, and shadow, the more your confidence will grow. As you become more knowledgeable, you’ll find it easier to step into any clinical setting, knowing you have the skills and understanding to make a difference. This confidence will be evident to your team, showing your willingness to grow and support the clinic.

One of the best traits in healthcare is initiative, something you can’t easily teach. Over my seven years as an MA, I’ve trained several MAs and new LPNs. The most successful ones were those who took ownership of their learning, consistently sought new knowledge, and looked for ways to contribute to the team. Healthcare demands this drive and passion, and by committing to lifelong learning, you’re showing your team and your patients that you’re serious about their care.

Not only will you become a more valuable team member, but you’ll also position yourself as a professional asset. Your confidence, curiosity, and continuous learning will make you a standout candidate in any future job or promotion.

Final Thoughts

Becoming a great MA isn’t just about doing tasks—it’s about engaging, learning, and asking questions that make you a more knowledgeable and capable healthcare professional. Remember, every question, shadowing opportunity, and moment of curiosity contributes to your growth. Embrace each one, and you’ll find that your knowledge, confidence, and respect from your team will grow along with it.
