Eyes And Ears Disorder care Quiz

Snellen's Test is used to assess visual acuity. It involves reading letters of various sizes from a distance of 20 feet. The test measures how well a person can see and identify letters at a specified distance, which helps determine the clarity and sharpness of their vision. Ishihara Plate is used to test for color blindness, Retinoscopy is used to determine the refractive error of the eye, and Tonometry is used to measure intraocular pressure.

The diet for a client with Meniere's disease should be low in sodium. Meniere's disease is a disorder of the inner ear that can cause episodes of vertigo, hearing loss, and tinnitus. Excess sodium intake can worsen the symptoms of Meniere's disease by causing fluid retention in the inner ear, leading to increased pressure and fluid imbalance. Therefore, a low-sodium diet is recommended to help manage the symptoms and reduce the frequency and severity of the episodes.

The nursing diagnosis that should take priority for a client diagnosed with Meniere's disease is "Risk for injury". Meniere's disease is a disorder of the inner ear that can cause sudden episodes of vertigo, hearing loss, and tinnitus. These symptoms can significantly impact the client's balance and coordination, increasing the risk of falls and injuries. Therefore, the priority nursing diagnosis would be to address and minimize the risk of injury for the client.

After cataract extraction, it is important for the client to maintain adequate hydration to prevent dehydration and promote healing. Therefore, limiting fluid intake would not be an appropriate nursing intervention in this case.

Using a high-pitch voice is an inappropriate nursing intervention for a client with hearing impairment. Hearing impairment often affects the ability to hear high-frequency sounds, so speaking in a high-pitch voice may make it even more difficult for the client to understand. It is important to speak in clearly enunciated words using a normal tone of voice, talk directly in front of the client, and use speech with gestures to enhance communication for a client with hearing impairment.

The primary problem in cataract is blurring of vision. Cataract is a condition where the lens of the eye becomes cloudy, causing vision to become blurry or hazy. This cloudiness prevents light from passing through the lens properly, resulting in a loss of sharpness and clarity in vision. As the cataract progresses, the blurring of vision becomes more pronounced, making it difficult to see clearly. Other symptoms such as sensitivity to light and difficulty seeing at night may also occur, but blurring of vision is the main issue caused by cataract.

Otosclerosis is a condition characterized by the replacement of normal bones in the ear with spongy and highly-vascularized bones. This leads to the fixation of the stapes, one of the small bones in the middle ear, with the oval window. This fixation hampers the transmission of sound vibrations from the middle ear to the inner ear, resulting in hearing loss.

Atropine SO4 is not administered to clients with glaucoma because it is a mydriatic agent that dilates the pupils. In glaucoma, there is an increase in intraocular pressure, and dilation of the pupils can further worsen the condition by blocking the outflow of fluid from the eye. Therefore, Atropine SO4 is contraindicated in glaucoma. Diamox (Acetazolamide), Pilocarpine, and Timolol maleate are commonly used drugs in the treatment of glaucoma as they help reduce intraocular pressure.

Meniere's Disease is a disorder of the inner ear that affects balance and hearing. The most characteristic manifestation of this condition is vertigo, which is a sensation of spinning or dizziness. Vertigo is often accompanied by other symptoms such as tinnitus (ringing in the ears), hearing loss, and a feeling of fullness in the affected ear. Headache, nausea, and vomiting may occur during severe episodes of vertigo but are not the primary characteristic of Meniere's Disease.

Rinne's test is a diagnostic test that compares air conduction with bone conduction. It involves placing a vibrating tuning fork on the mastoid bone behind the ear and then in front of the ear. The test is used to determine if there is a conductive hearing loss, where bone conduction is better than air conduction, or a sensorineural hearing loss, where air conduction is better than bone conduction.

A client who had cataract should be told to call his MD if he has eye pain. Eye pain can be a sign of complications or infection after cataract surgery. It is important for the client to seek medical attention in order to prevent any further damage or complications to the eye. Blurred vision and glare are common symptoms experienced by clients with cataract and are expected after the surgery.

Enucleation is the correct answer because it refers to the surgical procedure of removing the entire eyeball while preserving the surrounding tissues and muscles. This procedure is typically performed in cases of severe eye trauma, uncontrollable eye pain, or to treat certain types of eye cancer. Evisceration, on the other hand, involves removing the contents of the eyeball while leaving the sclera intact. Exanteration is the removal of the entire eye along with the surrounding tissues, while extraction refers to the removal of a foreign object or cataract from the eye.

Positioning the client on the operated side after ear surgery is not an appropriate nursing intervention. This position may put pressure on the surgical site and potentially cause complications. It is important to maintain the client in a position that promotes comfort and prevents any harm or strain to the surgical site.

The correct answer is "When assisting the client during ambulation, the nurse stays beside the client." This is the incorrect nursing intervention for a blind person because it does not promote independence. A blind person should be encouraged to use a cane or other assistive device to navigate their surroundings independently. The nurse should instead provide verbal cues and guidance while allowing the client to take the lead in ambulation.

When a client has a foreign body protruding from the eye, the priority nursing intervention is to irrigate the eye with sterile saline. This is important because it helps to flush out the foreign body and prevent further damage to the eye. Irrigating the eye with sterile saline can also help to alleviate any discomfort or pain that the client may be experiencing. Assessing visual acuity with Snellen's chart, removing the foreign body with sterile gauze, and patching both eyes until seen by an Ophthalmologist are important interventions, but they are not the priority in this situation.

Performing an iridectomy after cataract extraction is done to prevent secondary glaucoma. Secondary glaucoma can occur due to various factors such as pupillary block, inflammation, or angle closure caused by the iris blocking the drainage angle. By performing an iridectomy, a small portion of the iris is removed, creating a new opening for the aqueous fluid to flow freely and preventing the buildup of intraocular pressure that can lead to glaucoma. This procedure helps to maintain the health of the eye and prevent potential complications.

Hyperopia, also known as farsightedness, is a condition where distant objects are seen more clearly than near objects. It occurs when the eyeball is shorter than normal or when the cornea is not curved enough. A convex lens is used to correct hyperopia by converging light rays before they enter the eye, allowing the image to focus properly on the retina. The convex lens helps to increase the focusing power of the eye, enabling the person to see nearby objects more clearly. Therefore, a convex lens is the correct choice for correcting hyperopia.

Presbyopia is the correct answer because it is an eye disorder that is characterized by a lessening of the effective powers of accommodation. This means that the eye's ability to focus on near objects gradually decreases with age, making it difficult to see things up close. Myopia, on the other hand, is nearsightedness and is not related to a decrease in the eye's focusing ability. Hypertropia is a condition where there is an upward deviation of one eye, and presbycusis is age-related hearing loss, which is unrelated to the eye.

Glaucoma is a condition characterized by irreversible blindness. This means that once vision loss occurs due to glaucoma, it cannot be reversed or restored. Glaucoma is caused by damage to the optic nerve, often due to increased pressure within the eye. It is a progressive disease that can lead to gradual vision loss, starting with the peripheral vision and eventually affecting central vision as well. Treatment for glaucoma typically involves reducing intraocular pressure through the use of medications, surgery, or other interventions. Mydriatics, on the other hand, are drugs used to dilate the pupils and are not specifically used to treat glaucoma.

Positioning the client with the area of detachment dependent is not an appropriate nursing intervention for a client with retinal detachment who has undergone scleral buckling. The correct position for a client with retinal detachment is to keep the head of the bed elevated to promote drainage and decrease intraocular pressure. Positioning the client with the area of detachment dependent could potentially worsen the detachment and increase the risk of complications.

A chalazion is a sterile chronic granulomatous inflammation of the meibomian gland. The meibomian glands are located in the eyelids and produce an oily substance that helps lubricate the eyes. When the gland becomes blocked, it can lead to the formation of a chalazion. Chalazions are typically painless and appear as a firm, non-tender lump on the eyelid. They can cause swelling and redness, and if they become large enough, they may cause blurred vision. Treatment options include warm compresses, eyelid hygiene, and in some cases, surgical removal.

Pterygium is a condition characterized by the growth of a fleshy tissue on the white part of the eye. It is primarily caused by exposure to dust. When dust particles enter the eye, they can irritate the conjunctiva, leading to inflammation and the formation of a pterygium. Dust particles can also cause dryness and abrasion on the surface of the eye, further contributing to the development of this condition. Therefore, regular exposure to dust increases the risk of developing pterygium.

Retinal detachment occurs when the retina, the layer of tissue at the back of the eye responsible for vision, becomes separated from its underlying supportive tissue. This condition often presents with symptoms such as floating spots before the eyes, flashes of light, and progressive constriction of vision in one area. However, pain in the eye is not typically associated with retinal detachment. Therefore, the client with retinal detachment would least likely manifest pain in the eye.

In acute glaucoma, the obstruction to the flow of aqueous humor is caused by displacement of the iris. When the iris is displaced, it can block the drainage angle, which is where the aqueous humor normally flows out of the eye. This blockage leads to an increase in intraocular pressure, causing symptoms such as severe eye pain, blurred vision, and redness. Prompt medical attention is required to relieve the blockage and prevent further damage to the optic nerve.
