NCLEX Review on Cardiac Arrythmias

a nurse is caring for a client who has a history of dysrhythmias This is a topic that many people are looking for. 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, would like to introduce to you NCLEX Review on Cardiac Arrythmias. Following along are instructions in the video below:
Guys how is everybodys review going now if you do hear some noises and and scratches in the background that would be my silly cat running around and making so please excuse and my apologies for the noises so again today. We will talk about this arrhythmia. So first lets take a look at cardiac dysrhythmia are what is also known as cardiac arrhythmia right or what we call an irregular heartbeat.
Now this can be a group of conditions in which the heart beat like i said a while ago is irregular. Which means it can either be too fast or too slow now we all know that a heart beat that is too fast. Which is above usually above 100 beats per minute in adults.
Its called tachycardia in a heartbeat that is too low or too slow. I meant is this below 60 beats per minute. Its obviously called a bradycardia now understand that many arrhythmias have no symptoms okay now when symptoms are present.
They may be they may include palpitations or feeling kind of a slight pause between heartbeats. More seriously. There can be like headedness right shortness of breath or chest pain.
But for the most part it can usually be asymptomatic. Now. While most arrhythmias are not serious.
Some are actually pretty spoke and predispose. A person to complications such as a stroke or heart failure. So therefore.
Its nurses who need to be mindful of this okay now even worse others can result into cardiac arrest right. Which can be really serious now. Heres my cat again now take note that arrhythmias will play a big role in the cardiac section of your next exam.
So yes. It is important and you do have to know the basics okay now first im going to talk about the various types of arrhythmias and im going to simplify this as easily as possible since it can get quite complicated okay now there are four types of arrhythmias. Which is which can be simplified in in groups.
Okay. Theres the extra beats right. Theres the supraventricular.
So perpendicular tachycardias next group would be the ventricular arrhythmias and lastly would be our brady arrhythmias. Okay again im very sorry for all that click and clattering in the background. The background noise.
That will be my silly energetic cat playing with the wires under my foot. Now lets begin with extra beats. What are extra beats now first we all know that the hearts pumping action is driven by electrical stimulation within the heart muscle right and the hearts electrical system.
Allows it to beat in an organized pattern. Now these electrical signals in your heart can become blocked right or irregular and this causes a disruption in your hearts normal rhythm okay now heres where extra beats occur. A premature heartbeat is basically an extra beat between two normal heart beats alright and it usually occurs in the ventricles before they had time to fill with blood after a regular heart beat.
Again. Im sorry for the background noises. Now extra beats usually include the two premature contractions.
Which are which are your premature. Atrial contractions and premature. Ventricular contractions.
Or what we what is known as pvcs. Now after doing a few case studies by asking recent nclex acres. You know what they thought was mostly pretty.
Prominent in the nclex exam. A few have told me about pvcs or premature ventricular contractions so im gonna dig deeper into that okay so premature ventricular contractions or pvcs what are they all right there. It can also be called pv bs actually which means premature.
Ventricular b.s now theyre basically early contractions that occur obviously when the ventricles right the lower chambers of the heart contract out of sequence with the normal heart rhythm and usually theyre generally harmless and usually they dont require treatment right. But it has been known that pvc can cause a more serious arrhythmias in people with heart disease or a history of ventricular tachycardia.
Which can be very serious. Okay. Now a similar question has been asked in an nclex exam pertaining to pvc or premature.
Ventricular contractions. Right and question involved caring for a patient who has sustained an mi or myocardial infraction right and the nurse notes that. 8.
Pvc was visible in one minute at the cardiac monitor. Okay now the client is receiving an iv infusion of d5w. Which is dextrose in an oxygen level of two liters per minute.
Okay. Now the question asks what the nurses first course of action should be right would it be to first increase the iv infusion rate right second choice would be to notify the physician promptly third would be to increase the oxygen concentration or would it be lastly to administer a prescribed and ill jisuk right now like i mentioned before pvcs are often a precursor to life threatening dysrhythmias right. Including meatsac or ventricular.
Tachycardia and v. Fib than tricular fibrillation. Now an occasional pvc is not considered dangerous.
But if pvcs occur at a rate greater than five or six per minute especially. In a post mi client right the physician should be notified immediately okay. So obviously.
The answer would be to notify. The physician as soon as possible because more than more than six pvcs per minutes considered serious and it usually calls for a decrease in ventricular irritability. And its very necessary for the to call the physician.
Because the physician might lets say administer medication such as lidocaine okay now the first choice which was increasing the iv infusion rate. Its not gonna do anything in regards to decreasing the number of pvcs right and the other choice. Which is increasing the oxygen concentration.
It could be a possible answer. But it should not be the nurses first course of action. Okay rather.
The nurse should notify the physician promptly now the third on the other choice. Which is administering. The prescribed jisuk.
Obviously would not decrease. The ventricular irritability or make any impact and the patients condition specifically with the pbc contractions. Okay now again pvcs are very important and all your pvcs and this is it for now guys okay trying to make these videos you know short and simple and i will go over more the various types and groups of arrhythmias in the next.
Few videos. Okay again. Thank you so much for your time.
Its deeply deeply greatly appreciated and if you do want to help support me you know doing these videos in some in some kind of way just please visit all nursing notes calm right. Theres a review course. Thats available over there theres help plenty about nclex takers pass or exam.
Again. Its an all nursing notes calm. You know take a look at all the the contents of bell bone there again thank you so much guys i really really appreciate your time good luck on your exam and god bless bye bye .
