Final answer:
Propranolol is a ß-blocker used to treat high blood pressure by blocking receptors that affect heart rate and blood vessel dilation. A statement by the teen that shows misunderstanding of the medication's continuous use or its potential side effects indicates the need for further education.
Step-by-step explanation:
Propranolol is a medication that belongs to a class of drugs known as ß-blockers, which are commonly prescribed to treat conditions like high blood pressure (hypertension) and heart failure. These medications work by blocking ß-receptors such as beta-1 receptors, which are involved in the effects of adrenaline on the heart. By blocking these receptors, propranolol effectively slows down heart rate (HR) and allows blood vessels to dilate, leading to a decrease in blood pressure.
If a statement by a teen indicates they believe they can stop taking propranolol once their blood pressure is lowered or if they misunderstand the risk of potential side effects like bradycardia (abnormally slow heart rate) or heart stoppage, this would demonstrate the need for further instruction. It's crucial that patients understand the importance of taking the medication as prescribed and are aware of the potential side effects and the reason behind continued medication even if symptoms improve.
