EYES
Which chronic eye disorder is caused by opacity or clouding of the lens?
Answer: Cataracts
Rationale: Cataracts are caused by opacity or clouding of the lens, producing foggy vision, dulled colors, glare, and gradually worsening night then day vision (safety).
Nursing implication: Assess visual safety, reduce fall risk, improve lighting and contrast, and reinforce that definitive treatment is cataract removal or lens replacement when function is impaired.
This infection or inflammation of the middle ear — most common in young children due to structural differences in the Eustachian tube and adenoid enlargement — is treated with oral or ototopic antibiotics and antipyretics.
CORRECT ANSWER: Acute Otitis Media
RATIONALE: Acute otitis media is infection or inflammation of the middle ear. The lecture identifies structural differences in young children (shorter, more horizontal Eustachian tubes) and adenoid enlargement as the primary contributing causes. Manifestations include ear pain and crying/irritability. Diagnosis includes history, examination, drainage culture, and hearing test. Treatment includes oral/otologic antibiotics and antipyretics.
NURSING IMPLICATIONS: Assess for ear pain, crying/irritability, and fever in pediatric patients. Administer prescribed antibiotics and antipyretics as ordered. Educate caregivers on completing the full antibiotic course even when symptoms improve, and the importance of follow-up to confirm resolution. Teach that bottle-feeding in the supine position increases risk. Assess hearing following resolution to identify any persistent conductive hearing loss.
This age-related condition of the eye — caused by the lens becoming yellowed, less flexible, and slightly cloudy — makes it increasingly difficult to focus on near objects and is the most common reason older adults need reading glasses.
CORRECT ANSWER: Presbyopia
RATIONALE: Presbyopia is listed in the lecture as a sensory condition associated with aging — the lens loses its flexibility and ability to accommodate for near vision. Related aging changes listed in the lecture include decreased tear production, smaller and less reactive pupils, corneal insensitivity, weakened eye muscles, and decreased fat pad support. These changes collectively impair vision in older adults.
NURSING IMPLICATIONS: Screen for near vision changes at every encounter in adults over 40. Ensure patients have access to appropriate corrective lenses. In the clinical setting, provide adequate lighting, use large-print materials, and ensure written instructions are legible without magnification. Assess the impact on medication self-administration (reading pill bottles), driving, and fall risk. Refer to ophthalmology for corrective lens evaluation.
A child pulls at the ear, cries frequently, and recently had a viral upper respiratory infection. What condition should the nurse suspect first?
Answer: Acute otitis media
Rationale: Acute otitis media is infection or inflammation of the middle ear, often after a viral URI, and is common in children because their Eustachian tubes are shorter, straighter, and narrower.
Nursing implication: Assess pain, fever, hearing changes, and complications; teach medication adherence, fluid intake, comfort measures, and when recurrent disease needs further evaluation.
Which eye disorder involves deterioration of the macular area of the retina and commonly affects central vision?
Answer: Macular degeneration
Rationale: Macular degeneration damages the macula and primarily affects central vision; dry disease progresses slowly, while wet disease causes more sudden distortion and rapid loss.
Nursing implication: Monitor central-vision changes, teach use of an Amsler grid and low-vision aids, address smoking cessation and safety, and reinforce follow-up for wet-disease treatment.
Which age-related hearing condition commonly affects high-frequency sounds?
Answer: Presbycusis
Rationale: Presbycusis is age-related hearing loss that commonly affects high-frequency sounds first and may make speech discrimination harder.
Nursing implication: Face the patient, reduce background noise, speak clearly but not by shouting, and assess for reversible contributors such as cerumen impaction.
A patient exposed to a loud explosion now has tinnitus, dizziness, and bloody ear drainage. What broad type of sensory disorder is this?
Answer: Ear trauma or acoustic trauma
Rationale: Ear trauma can result from foreign objects, insects, or acoustic injury from explosions or gunshots and may cause tinnitus, dizziness, drainage, and hearing loss.
Nursing implication: Avoid blind probing, remove only clearly visible simple objects per policy, limit further noise exposure, and monitor for tympanic membrane injury or persistent deficits.
A swimmer develops ear pain, itching, fullness, and drainage that worsens when the outer ear is touched. Which disorder is most likely?
Answer: Otitis externa
Rationale: Otitis externa is infection or inflammation of the external ear canal, often related to retained moisture or local trauma; pain worsens with auricle movement.
Nursing implication: Keep the canal dry, avoid inserting objects, administer prescribed ear drops correctly, and monitor for worsening pain, swelling, or spreading infection.
What visual symptom is classic for retinal detachment before major vision loss occurs?
Answer: Flashes of light, floaters, and a curtain-like visual-field loss
Rationale: This answer matches the sensory alteration patterns emphasized in the lecture, especially identifying the affected structure, hallmark symptoms, and major cause.
Nursing implication: Tie the finding to safety, focused assessment, prompt referral when vision or hearing is threatened, and patient teaching about prevention and follow-up.
Which chronic inner-ear disorder causes episodes of vertigo, tinnitus, unilateral hearing loss, and a feeling of fullness?
Answer: Ménière’s disease
Rationale: Ménière’s disease is linked to endolymph swelling in the inner ear and causes episodic vertigo, tinnitus, unilateral hearing loss, and ear fullness.
Nursing implication: Prioritize safety during attacks, reduce fall risk, manage nausea/vertigo, teach sodium reduction and trigger avoidance, and support hearing/balance follow-up.
A patient splashes a chemical into the eye. What should be the immediate first intervention before anything else?
Answer: Flush the eye immediately with sterile saline or water per emergency protocol
Rationale: This answer matches the sensory alteration patterns emphasized in the lecture, especially identifying the affected structure, hallmark symptoms, and major cause.
Nursing implication: Tie the finding to safety, focused assessment, prompt referral when vision or hearing is threatened, and patient teaching about prevention and follow-up.
A parent says one of their child's eyes seems to drift and the child sometimes sees double. Which eye disorder should be suspected?
Answer: Strabismus
Rationale: Strabismus is gaze deviation caused by poor eye alignment; if prolonged, the brain may suppress input from one eye and visual development can worsen.
Nursing implication: Screen early, reinforce patching/exercises or prism use as ordered, and refer promptly to prevent amblyopia and long-term visual deficits.
Why can open-angle glaucoma be overlooked or mistaken for a normal age-related vision change?
Answer: Because it is painless and develops gradually over time
Rationale: This answer matches the sensory alteration patterns emphasized in the lecture, especially identifying the affected structure, hallmark symptoms, and major cause.
Nursing implication: Tie the finding to safety, focused assessment, prompt referral when vision or hearing is threatened, and patient teaching about prevention and follow-up.
Which disorder involves hearing abnormal noises such as ringing, buzzing, or roaring in the ears?
Answer: Tinnitus
Rationale: Tinnitus is perception of sound without an external source and may be linked to hearing loss, noise exposure, Ménière’s disease, cerumen, vascular causes, stress, or ototoxic drugs.
Nursing implication: Review medications and noise exposure, assess for distress or sleep disruption, and teach use of hearing protection, white noise, and follow-up for underlying causes.
How would you differentiate viral from bacterial conjunctivitis using the exudate description?
Answer: Viral drainage is watery or mucus-like; bacterial drainage is thicker yellow-green
Rationale: This answer matches the sensory alteration patterns emphasized in the lecture, especially identifying the affected structure, hallmark symptoms, and major cause.
Nursing implication: Tie the finding to safety, focused assessment, prompt referral when vision or hearing is threatened, and patient teaching about prevention and follow-up.
A patient develops sudden severe unilateral eye pain, nausea, vomiting, and halos around lights after being in a dark theater and then entering bright light. Which condition is this patient experiencing?
Answer: Angle-closure glaucoma
Rationale: Angle-closure glaucoma is a sudden blockage of aqueous humor outflow that sharply raises intraocular pressure and causes severe pain, halos, nausea, and a hazy cornea.
Nursing implication: Recognize this as an emergency, reduce delay to treatment, control symptoms as ordered, and prepare the patient for pressure-lowering therapy and possible iridotomy.
What mechanism causes amblyopia to become permanent if it is not treated early in childhood?
Answer: The brain suppresses input from the weaker eye during visual development
Rationale: This answer matches the sensory alteration patterns emphasized in the lecture, especially identifying the affected structure, hallmark symptoms, and major cause.
Nursing implication: Tie the finding to safety, focused assessment, prompt referral when vision or hearing is threatened, and patient teaching about prevention and follow-up.
Which chronic middle-ear disorder results from abnormal bone growth and often causes progressive conductive hearing loss?
Answer: Otosclerosis
Rationale: Otosclerosis is abnormal bone growth in the middle ear that limits sound transmission and usually causes progressive conductive hearing loss; tinnitus or vertigo may occur too.
Nursing implication: Monitor functional hearing loss, support hearing-aid use or surgical planning, and teach communication strategies and follow-up testing.
Which maternal infection is specifically highlighted as vaccine-preventable and linked to congenital hearing loss?
Answer: Rubella
Rationale: Maternal rubella is a vaccine-preventable infection associated with congenital hearing loss and other fetal complications.
Nursing implication: Use prenatal and preconception teaching to reinforce vaccination, infection prevention, and the importance of early prenatal care.
