a nurse is assessing a client who has dilated cardiomyopathy This is a topic that many people are looking for. bluevelvetrestaurant.com is a channel providing useful information about learning, life, digital marketing and online courses …. it will help you have an overview and solid multi-faceted knowledge . Today, bluevelvetrestaurant.com would like to introduce to you Dilated Cardiomyopathy (DCM) for Nursing l NCLEX. Following along are instructions in the video below:
Guys nurse mike here and welcome to simple nursing calm before we get todayss lectures started. Please remember to access your free quiz and preview. Our cool nifty study guides not here on youtube.
Click the link right up here at any time during this video. All right guys. Lets begin classic heart.
Failure. Signs and symptoms all revolving around low oxygen signs and symptoms from this below cardiac output. So low oxygen in the brain will see syncope as well as mental status changes.
Now exams in the nclex love to really emphasize that restlessness and agitation is the earliest signs of hypoxia so guys write that down restlessness and agitation are usually the first signs that indicate low oxygen. But well also see in the heart angina and ecg dysrhythmias are basically a heart block and for the respiratory tract will see shortness of breath called dyspnea. So youll see rapid shallow breathing.
Now as far as heart failure. Signs and symptoms blood fails to pump forward and now starts to back up in the body and or the lungs. So blood backs up on the left side of the heart remember l.
For left means l. For lungs. We hear wet crackles inside the lungs known as pulmonary edema and r for right sided.
Heart failure. Which are means rocks the body with fluid so well see a swollen body with edema ascites. And even jvd jugular vein distension.
Now in this distended heart for dilated cardiomyopathy. We also see regurgitated in the bicuspid and tricuspid valves since the valves are loose from this distension. They dont close tight enough.
So remember regurgitation means a return of blood into the previous chambers. Fancy words for the blood isnt pumping forward. Were also gonna see narrowed pulse pressure.
Which is where the blood pressure numbers get closer and closer together for example our normal blood pressure is 120 over 80. But it starts getting closer and closer together turning into 110 over 90. Now this is a very difficult topic for most students to grasp.
But guys please just understand that cardiac output is dropping and lastly. It will hear a murmur near the s3 location. And this is from the slamming of blood into the ventricles.
Sounding. A lot like this now as far as diagnostic test for dilated cardiomyopathy. Our chest.
X. Ray is gonna show an enlarged heart. Called cardiomegaly.
So guys remember a mega heart is cardiomegaly an echocardiogram a que just echo. We want to see the dilated and distended heart. We basically just want to see how thin those heart muscles are so we know how to evaluate how much blood is being pumped out of the heart measured in ejection fraction.
So ejection fraction of fifty five percent to seventy percent is normal. But guys dropping below forty percent. Usually indicates that the heart is in some type of heart failure and lastly.
An angiography is used to rule out ischemic heart disease. They basically just inject dye into the veins. Which acts like a highlighter to better visualize.
Any blockages of the artery or even poor oxygenated areas now as far as labs. Were gonna see a distended heart with elevated bnp b type or brain net hritik peptides. Which indicates nonspecific stretching or tearing and damage to the heart itself.
This is usually an indicator of fluid overload as in heart failure. But in dilated distended cardiomyopathy this works too since the ventricles are being stretched out and getting super distended and very thin like an overblown balloon. So think of a big balloon that is slowly stretched out under all that pressure guys.
This is exactly whats happening to our ventricles. We measure our bnp which means that anything over a hundred is not good. So over 300 is mild over six hundreds moderate thanks for watching for our full video and new quiz bank click right up here to access your free trial.
