For the pad (bladder) method, what should you do with the pad?

• A. Fill pad with water or gel
• B. Fill pad with air
• C. Leave pad dry
• D. Soak pad with scanning solution

Answer: (A)

For the pad/bladder method, you ensure proper acoustic coupling by filling the bladder with water or gel. This creates a continuous medium between the transducer and the skin, eliminating air gaps that would reflect ultrasound waves and reduce energy transfer. An air-filled or dry pad disrupts coupling, lowers treatment effectiveness, and can cause hotspots. Filling with water or gel provides consistent contact, helps distribute pressure evenly, and protects the skin. So, the correct approach is to fill the pad with water or gel.
