Bell and let’s dive in all right let’s talk about atenolol now atenolol’s trade name is to norman pharmacologic class is a beta blocker and its therapeutic class is an antihypertensive now it’s indications it’s used in the management of hypertension and angina which is chest pain and it also improves survival after a heart attack now it’s mechanism of action
A ton attentive blocks the stimulation of beta 1 which are myocardial adrenergic receptor sites now these receptor sites are usually occupied by catecholamines like epinephrine and norepinephrine and when they are blocked by atenolol it blocks the effects of epinephrine norepinephrine and other catecholamines now epinephrine norepinephrine and catecholamines
Usually cause an increase in cardiac conductivity and since the effects are being blocked it decreases their con conductivity from the sa and av node which decreases the heart rate and the contractility of the heart so blocking these receptor sites also decreases the run-in release which will decrease blood pressure as well since renin cannot be released from
The kidneys it prevents the renin angiotensin aldosterone system which would normally increase blood pressure but since it’s being blocked it decreases blood pressure there are also beta2 receptor sites located in the lungs and they’re usually not affected by a tunnel all since it blocks the stimulation of beta 1. now the therapeutic effect of this antennalol
Decreases the blood pressure the heart rate and cardiac conductivity now some side effects bradycardia and hypotension can have happen because it’s blocking those beta 1 adrenergic receptor sites in the heart it’s an easy way to remember this the side effect of the medication is to consider that when it works too well so in this case the heart rate and the blood
Pressure have lowered too much creating bradycardia and hypotension so if the medication works too well that’s what can happen low blood pressure bradycardia and hypotension now this lowered heart rate and blood pressure can also lead to dizziness weakness and fatigue now the some nursing assessment points to keep in mind monitor the patient’s heart rate and
Blood pressure and you want to watch out for any lows so monitor the patient’s lungs for crackles or any shortness of breath and these can be signs of heart failure daily weights and monitoring for edema will also be useful when monitoring for heart failure and liver and renal function tests should be monitored to be sure the patient can metabolize and excrete
The medication appropriately and now for some major contraindications do not use this in a patient with heart failure hypotension bradycardia or pulmonary edema since the effects of atenolol can enhance those symptoms and then monitor the dosage of a tunnel closely in patients with impaired renal or liver function and you may have heard the phrase start low and
Go slow so you’ll increase the dosage slowly over time as prescribed to give the cardiac system time to adjust and atonal is one of those medications that you will do this with in order to give the cardiac system time to adjust to it now patient education points educate the patient to take this medication exactly as prescribed and they should not skip a dose or
Stop it abruptly stopping abruptly or missing a dose could possibly lead to rebound hypertension or tachycardia it is important to inform the patient that it may take one to two weeks before they feel the benefit of the medication so they should not stop taking it when they feel better and this is not a cure but it’s long-term therapy to maintain a balanced cardiac
System and they should stand up slowly to avoid postural hypotension and when initiating therapy or dosing adjustments they should monitor for dizziness then educate them to watch for signs of rapid weight gain or shortness of breath and this could be signs of edema caused by heart failure and you should teach your patient how to do a daily pulse check in order
To monitor for bradycardia now if they’re taking this medication for high blood pressure patients should also make lifestyle changes such as eating a low salt diet low fat diet maintaining a healthy weight and then exercising regularly quitting smoking and then drinking alcohol only in moderation then some nursing considerations to keep in mind a tunnel all may
Mask the signs and symptoms of hypoglycemia so it’s important to be aware of this and then safety is a big concern with any dosage adjustment since dizziness from that postural hypotension is common and that is what you need to know about a tunnel now if you want to deep dive into all the other medications that you need to learn in nursing school do not miss the
