Myasthenia Gravis Nursing Assessment and Treatment | Nursing Lecture
In this video, we're walking through the nursing assessment and treatment for myasthenia gravis. We won't stop there, we're going to walk through the critical thinking behind it all, so you know why you are doing it.
Myasthenia Gravis Pathophysiology:
Myasthenia Gravis is a neurological condition that prevents muscles from contracting like they should.
Myasthenia Gravis Nursing Assessment:
Safety concerns
Vision
Ability to swallow and their gag reflex
Respiratory effort and monitor their respiratory muscles for involvement
Tensilon Test:
The medication Tensilon (or edorphonium) is an acetylcholinesterase inhibitor and it prevents the natural breakdown of acetylcholine. By preventing acetylcholine from being naturally broken down, it keeps more of it present at the neuromuscular junction and helps to flood the receptors and increase the chances of acetylcholine binding to any receptors that aren't yet blocked by autoantibodies.
If there is improvement in muscle contraction and lack of weakness, then the test is positive for myasthenia gravis.
Myasthenic Crisis:
This is when the respiratory muscles are quickly weakening, or they are already weakened, which can lead to respiratory failure. If Tensilon is given and they temporarily become better, then they are in a myasthenic crisis.
Nursing Interventions for Myasthenia Gravis:
In the video, we'll walk through the critical thinking for each of these and why you might do them. So you won't need to memorize this list because you'll actually understand the critical thinking behind each of these for your nursing exam.
