South Dakota Medication Aide Practice Test

The correct choice identifies Viagra, Cialis, and Levitra as the commonly used medications for erectile dysfunction (ED). These medications are classified as phosphodiesterase type 5 (PDE5) inhibitors, which work by relaxing blood vessels and increasing blood flow to the penis, thereby facilitating an erection when sexually stimulated. Each of these medications has its own unique features, such as duration of action and onset time, but they all serve the primary purpose of treating ED.

The other options consist of medications used for different conditions. Zoloft, Prozac, and Wellbutrin are primarily prescribed for depression and anxiety disorders. Avodart, Proscar, and Flomax are used for conditions related to prostate health and urinary function, not erectile dysfunction. Alprazolam, Diazepam, and Lorazepam are benzodiazepines primarily used for anxiety and panic disorders, and do not treat erectile dysfunction. Understanding the specific indications for each medication helps clarify why the chosen option is appropriate for addressing ED.
