Ateneo de Zamboanga University College of Nursing NURSING SKILLS OUTPUT (NSO) Report No. 1 EAR DROPS INSTILLATION & EAR IRRIGATION I. DESCRIPTION: Ear drops instillation: Medication can be introduced into the ear to soften wax‚ relieve pain‚ or treat disease. The instillation of medication to the ear is a clean procedure‚ except when the tympanic membrane is not intact‚ in which case sterile technique is needed. Ear irrigation: Before an ear can be irrigated‚ it must be examined with

changes‚ which move away from the machine and radiate to the individual’s location across the room. The waves reach the outer ear‚ which contains structures known as the pinnae‚ angled such that sound waves bounce off them and resonate. They enter the auditory canal after being significantly amplified before reaching the tympanic membrane. The waves strike the membrane and cause it to vibrate‚ which subsequently transmits them to the middle ear. The ossicles are three bones (malleus‚ incus and stapes)

iffany Goff Margaret Jenkins General psychology 7/11/04 Structures of the eye and ear We use our ears for the hearing sense‚ and we use our eyes for vision. Both are very important senses and would be hard to get along without. We rely on hearing for communication‚ navigation‚ entertainment and many other purposes Now for our eyes we use them for vision‚ their like our own personal camera’s‚ both have and use lens to focus on images.

travel along the outer ear and vibrate tympanic membrane. This vibration is transferred along the malleus‚ incus‚ and stapes. The mechanical vibration is then taken up as energy by the inner ear and is transmitted as an action potential along the auditory nerve to the brain‚ where it is interpreted. There are two main types of deafness: conductive and perceptive. These are divided into many other types based on their cause‚ symptoms‚ treatment. Conductive hearing loss occurs when conduction of

In the eye where the detachment occurred‚ a loss of color vision and visual acuity would occur. But Dan could use rods and still have some peripheral vision. 7.Muscles of the tensor tympani and stapedius serve a protective function by tensing the auditory ossicles preventing damage to the inner ear neurons. 8.The tympanic membrane is composed of epithelial and connective tissues that readily regenerate. The inner ear is mostly composed of neural tissues. Neurons do not heal well and can rarely be

Wind Chimes Wind chimes produce clear‚ pure tones when struck by a mallet or suspended clapper. A wind chime usually consists of a set of individual alloy rods‚ tuned by length to a series of intervals considered pleasant. These are suspended from a devised frame in such a way that a centrally suspended clapper can reach and impact all the rods. When the wind blows‚ the clapper is set in motion and randomly strikes one or more of the suspended rods-- causing the rod to vibrate and emit a tone

it should. •It may occur in more than one part of the ear. •1. DEAF-full or partial decrease in the ability to detect or understand sounds. Deaf usually caused by : - Eardrum is torn-cannot function - Ossicle bone fused together-can’t vibrate - Auditory nerve damaged by loud sound - Cochlea damage due to sickness/ drugs •2. Temporary hearing loss-build-up of earwax •3. Presbycusis- hearing loss related to aging and other factors. Correcting hearing defects •Syringes and warm water –remove wax
