BETA BLOCKERS REVIEW

There are different types of beta blockers. Undergraduate nursing school focuses mostly on Beta 1 and Beta 2 receptors. Beta 1 receptors effect the heart. Beta 2 receptors are located in the lungs (bronchioles) (among other places in the body).

Selective beta blockers, like atenolol and metoprolol, block beta 1 receptors. Therefore, they are sometimes referred to as cardio-selective. Nonselective beta blockers, like propranolol, block BOTH beta 1 and beta 2 receptors. These medications should be avoided in patients with asthma and COPD because they block beta 2 receptors, which can lead to bronchoconstriction or bronchospasm.

In this video I cover the absolute essentials that you must know about beta-blockers in order to be successful on your nursing exams, NCLEX, and in your career. I cover usage, adverse/side effects of beta-blockers, and how beta-blockers work. I also go over nursing implications for beta-blockers.
