The practical nurse (PN) assigns an unlicensed assistive personnel (UAP) to clean the hearing aid of an older adult resident of a long-term care facility. Which instructions should the PN provide to the UAP? (Select all that apply.)

A. Remove ear wax from the device's surface: Cleaning visible ear wax from the hearing aid prevents blockage of sound and maintains device function. The UAP should use a soft, dry cloth or brush to gently remove debris without using liquids or inserting objects into the device. B. Keep the battery door closed during storage: The battery door should remain open when not in use to preserve battery life and prevent moisture buildup. Keeping it closed may cause corrosion or battery drainage. C. Store the device on window sill to prevent loss: Placing the device on a window sill exposes it to sunlight and temperature fluctuations, which can damage internal components. The hearing aid should be stored in a dry, safe, and designated location. D. Observe and report any ear drainage after removing the device: Ear drainage may indicate infection, irritation, or injury caused by the hearing aid. Reporting this promptly allows timely evaluation and prevents complications or worsening of ear conditions. E. Verify that the device is labeled with client's identification: Labeling ensures the correct device is returned to the right resident, preventing mix-ups in shared living facilities where many residents use similar hearing aids.
