The video provides a concise, nursing‑focused review of atenolol (Tenormin), a beta‑1 selective blocker used to treat hypertension, angina, and to improve post‑myocardial infarction survival. It explains atenolol’s pharmacologic class, therapeutic class, and primary indications, then details its mechanism of action: blockade of myocardial β1‑adrenergic receptors, leading to reduced heart rate, contractility, SA/AV node conduction, and decreased renin release, ultimately lowering blood pressure. The presenters enumerate common adverse effects (bradycardia, hypotension, dizziness, fatigue) and serious risks, linking them to excessive β1 blockade. They outline essential nursing assessments—monitoring heart rate, blood pressure, lung sounds, daily weights, and renal/hepatic function—and highlight contraindications (heart failure, existing hypotension/bradycardia, pulmonary edema) and the need for cautious dose titration, especially in renal/hepatic impairment. Patient education points cover adherence, avoiding abrupt discontinuation, expected onset of benefit, lifestyle modifications, postural hypotension precautions, self‑pulse checks, and signs of fluid overload. Safety alerts note atenolol’s potential to mask hypoglycemia. The video concludes with promotional mentions of a free pharmacology cheat sheet and a Nursing SOS membership for deeper medication study.

In this video you will learn the side effects of atenolol and atenolol's mechanism of action. Now this my friend, is a super simple way to learn pharmacology faster and easier for nursing school. So don't worry my friend, you do not need to figure everything out yourself alone anymore for nursing school. We are here to help you out every step of the way. And of course, if you need more help with learning pharmacology in nursing school, be sure to download this free pharmacology cheat sheet that we have for you that walk you through how to study pharmacology, how to learn pharmacology step by step. Now the link is down below in the description for you to get that now hit that subscribe button and click the notification bell and let's dive in.
All right, let's talk about atenolol. Now atenolol's trade name is Tenormin. Pharmacologic class is a beta blocker and its therapeutic class is an antihypertensive. Now its indications it's used in the management of hypertension and angina, which is chest pain and improves survival after a heart attack. Now its mechanism of action, atenolol 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 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 renin 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 beta 2 receptor sites located in the lungs, and they're usually not affected by atenolol since it blocks the stimulation of beta 1. Now, the therapeutic effect of this atenolol decreases the blood pressure, the heart rate and cardiac conductivity. Now some side effects, bradycardia and hypotension can 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 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 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. Then 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 atenol 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 Atenolol 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 and then some nursing considerations to keep in mind. Atenolol 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 adjustments since dizziness from that postural hypotension is common and that is what you need to know about Atenolol.
