Canadian Practical Nurse Registration Examination (CPNRE) Practice Exam

The correct suffix that indicates the class of medications known as Beta Adrenergic Blockers is -lol. This suffix is prevalent in various medications used to manage conditions such as hypertension, heart failure, and certain types of arrhythmias. Examples of Beta Adrenergic Blockers that use this suffix include metoprolol, atenolol, and propranolol.

The reason this suffix is significant is that it helps healthcare professionals quickly identify the medication type and its primary action related to the sympathetic nervous system, specifically how it blocks beta-adrenergic receptors to decrease heart rate and cardiac output, which can lead to reduced blood pressure and improved heart function. Understanding the suffix -lol is critical for nurses and healthcare providers when prescribing, administering, or educating patients about their medications, as it provides insight into the dynamics of the treatment being provided.
