Let’s break down a nursing pharmacology staple—beta blockers—using a memory trick that helps you keep track of where these medications work in the body.

Beta blockers act on beta-adrenergic receptors, which are part of the sympathetic nervous system. Here's how to remember them:

Beta-1 = Heart ❤️ (You have 1 heart)
Beta-2 = Lungs 🫁 (You have 2 lungs)

Bonus: Beta receptors also exist on the uterus, which plays a role in preventing premature labor in high-stress situations—because the body isn’t prioritizing childbirth when trying to survive danger!

This short covers cardioselective vs nonselective beta blockers, and why it's important for nurses to know if a medication targets just the heart (like atenolol) or both heart and lungs (like propranolol). This distinction is especially important for patients with respiratory conditions like asthma or COPD, since nonselective beta blockers can cause bronchoconstriction.

Perfect for pharmacology review, nursing exams, and quick clinical decision-making!
