Hearing aids are electronic devices that amplify sound for people with hearing loss. They consist of a microphone that picks up sounds and converts them to electronic signals, an amplifier that increases the power of the signals, and a receiver that delivers the amplified sounds into the ear. There are different types of hearing aids including behind-the-ear, on-the-ear, in-the-ear canal, and bone-anchored options. Nurses play a role in helping patients understand how to use and care for their hearing aids.

Hearing Aids
This document provides information about hearing aids. It discusses what hearing aids are, when they are used, how hearing disorders are diagnosed, the different types of hearing loss, and methods of treatment including hearing aids, cochlear implants, and assistive devices. It describes the different parts of hearing aids, common repairs, and the process of assessment for hearing aids.
Hearing aids & implantable hearing devices
Hearing aids and implantable devices can help people with hearing loss. Conventional hearing aids consist of a microphone, amplifier and receiver. They come in different styles like behind-the-ear or in-the-ear. Bone anchored hearing aids use bone conduction to bypass the outer/middle ear. Cochlear implants have an internal and external component and provide electrical stimulation of the auditory nerve for severe-profound loss. Implantable hearing aids use direct mechanical vibration of the ossicles. Candidates for these devices have moderate-severe loss and limited benefit from conventional aids.
Speech therapy
This document provides an overview of speech therapy and communication disorders. It discusses that communication involves the exchange of information verbally and non-verbally. Speech disorders are classified as aphasia, dysarthria, or dysphonia. Aphasia is caused by brain damage and impairs language comprehension and use. Types of aphasia include Broca's, Wernicke's, and conduction aphasia. Dysarthria refers to motor speech defects from trauma or disease that affect articulation, loudness, and other speech aspects. Speech therapy treats conditions like cleft palate, cerebral palsy, autism, and Bell's palsy through techniques like imitation, repetition, listening, and sign
Presbycusis
Ms. Elizabeth presented on age-related hearing loss (presbycusis). It is a common condition linked to aging where hearing is slowly lost in both ears, with about 30 out of 100 adults over 65 having some hearing loss. Causes include long-term noise exposure, aging, genetics, certain health conditions, medications, race, income level, infections, and smoking. Symptoms are difficulty hearing conversations, high pitches, or sounds that seem too loud. Diagnosis involves tests of the ear canal, eardrum, hearing levels, and middle ear function. Treatments include hearing aids, assistive devices, speech reading, cochlear implants, and middle ear implants. Nursing considerations are involving family, speaking slowly
Communicating with hearing impaired and mute
This document provides tips for communicating effectively with people who have impaired hearing. Some key recommendations include speaking clearly and facing the person while speaking, maintaining eye contact, eliminating background noise, using short sentences to check for understanding, encouraging the use of hearing aids, using gestures to clarify statements, and allowing extra time for responses. It also suggests using written notes if unable to communicate verbally.
Cancer of larynx
Cancer of the larynx is a malignant tumor of the voice box that is most commonly squamous cell carcinoma. It occurs more frequently in men ages 50-70 who smoke or drink alcohol. Treatment depends on the cancer's stage but may include surgery, radiation therapy, and chemotherapy. Surgeries like laryngectomy remove part or all of the larynx and can permanently alter voice and breathing. Nursing care focuses on managing airway, communication, nutrition, and psychosocial issues during treatment and recovery.
Ototoxicity
Ototoxicity refers to ear poisoning caused by exposure to certain drugs or chemicals that damage the inner ear or auditory nerve. Common causes of ototoxicity include aminoglycoside antibiotics, loop diuretics, anti-malarials, and some cancer drugs. Symptoms range from mild tinnitus to total hearing loss. Diagnosis involves evaluating a patient's history of ototoxin exposure and conducting tests like electrocochleography and electronystagmography. Management focuses on discontinuing the ototoxic drug, treating any hearing or balance problems, and limiting future use of ototoxic medications.
Labyrinthitis
Labyrinthitis is inflammation of the inner ear labyrinth that can be caused by viral or bacterial infections, drugs, head injuries, or other conditions. It produces vestibular symptoms like vertigo and nausea as well as hearing loss. The infection can spread from the meninges, middle ear, or bloodstream. Bacterial labyrinthitis has toxic or suppurative forms, with the latter invading the inner ear directly. Diagnosis involves a history of ear problems and dizziness as well as physical exams and tests. Treatment focuses on relieving vertigo and nausea with drugs while antibiotics target bacterial causes. Surgery may be needed in severe cases. Complications can include meningitis, permanent balance issues
Nature and scope of mental health nursing
Psychiatric mental health nursing is a specialized area of nursing practice focused on promoting mental health through assessing, diagnosing, and treating behavioral problems, psychiatric disorders, and related conditions. The goals of psychiatric nursing are to promote mental health, prevent mental disorders, treat clients with mental disorders, and help restore their health. Psychiatric nurses work in a variety of clinical settings and perform activities like health promotion, screening and evaluation, case management, crisis intervention, and rehabilitation.
Meniere’s disease
Meniere's disease is a disorder of the inner ear that causes episodes of vertigo, hearing loss, and tinnitus. It was first described by Prosper Meniere in 1861. The cause is unknown but risk factors include metabolic, toxic, allergic, emotional, and circulatory disorders. Symptoms include vertigo, tinnitus, hearing loss, fullness, nausea, increased heart rate, and sweating. Diagnosis involves history, exams of the ear, and tests like audiograms and ENG. Treatment aims to control vertigo and tinnitus and preserve hearing using medications, diet changes, exercises, and sometimes surgery. Complications include permanent hearing or balance issues, anxiety, dehydration
Labrinthitis
Labyrinthitis is an inflammation or infection of the inner ear labyrinth that can be caused by viral or bacterial pathogens. It leads to symptoms like vertigo, hearing loss, tinnitus, and nausea. Diagnosis involves taking a medical history, physical examination, and audiogram. Treatment focuses on relieving symptoms like vertigo and nausea with medications. Antibiotics are used to treat bacterial infections while antiviral drugs may be used for viral causes. Nursing care aims to help the patient manage symptoms safely and prevent injury during acute vertigo attacks.
Otosclerosis
Otosclerosis is a condition where abnormal bone growth occurs in the middle ear, usually affecting both ears. This causes the stapes bone to become fixed, preventing sound vibrations from being transmitted effectively and resulting in conductive hearing loss. It is classified based on histological and clinical presentations. Diagnosis involves tests like audiometry and imaging. Treatment options range from hearing aids for mild cases to stapedectomy surgery to restore hearing by replacing or drilling the stapes bone.
Tympanic membrane perforation
This document discusses tympanic membrane perforation, which is a rupture of the eardrum. It can be caused by ear infections, trauma, or foreign objects in the ear canal. Symptoms include ear pain, bleeding, hearing loss, and drainage from the ear. Diagnosis involves examination of the ear. Small perforations may heal on their own with antibiotics and pain medication, while larger perforations require surgery like myringoplasty or tympanoplasty to repair the eardrum. Post-operative care involves keeping the ear dry and avoiding heavy lifting or air pressure changes for a few weeks.
Otalgia
Otalgia refers to ear pain or ear ache, which can be primary (originating in the ear) or referred (originating elsewhere but felt in the ear). Primary causes include infections, wax buildup, trauma, and tumors of the outer ear canal, eardrum, middle ear bones, inner ear, and mastoid bone behind the ear. Referred otalgia can occur via cranial nerves from areas like the teeth, throat, larynx, neck, or due to conditions like shingles. Risk factors include inserting objects in the ear, swimming in polluted water, and respiratory infections. Treatment involves relieving pain, promoting healing, restoring function, and removing foreign bodies through irrigation, antibiotics, surgery

Impacted wax
This document discusses impacted ear wax. It defines impacted wax as an excess collection of thick ear wax. Symptoms of impacted wax include diminished hearing of sudden onset, discomfort without pain usually, and occasionally tinnitus. Treatment options include using ear drops containing ceruminolytics for 4-5 days before syringing or using a wax hook to remove it. Self-care options are using ear drops to soften wax or olive oil warmed on a spoon. Ear irrigation can help hearing for those with impacted wax if done at low pressure, but should be avoided if the eardrum is perforated or in cases of mastoid surgery, chronic ear disease, unilateral deafness, or recurrent ear infections/tinnitus
Mastoiditis
Mastoiditis is an inflammation of the mastoid process behind the ear that can result from untreated or inadequately treated otitis media. It is classified as either acute or chronic mastoiditis. Acute mastoiditis develops as a complication of acute otitis media, while chronic mastoiditis occurs with chronic suppurative otitis media or cholesteatoma formations. Symptoms include severe pain, swelling and tenderness in the mastoid region, fever, and otorrhea. Diagnosis involves tests like CT scans, ear cultures and audiograms. Treatment consists of antibiotics, analgesics, and may require surgical drainage of pus via procedures like mastoidectomy if infection spreads to
