A nurse is assessing a 65-year-old client who reports gradual hearing loss over the past 2 years. Which assessment finding would be most characteristic of sensorineural hearing loss?
The client states, "I can hear people talking, but I can't understand what they're saying, especially in noisy places."
1Hearing improves when speaking loudly
2Bone conduction is greater than air conduction on Weber test
3Tympanic membrane appears red and bulging
4Difficulty discriminating high-frequency sounds and speech clarity✓ 정답
해설
Difficulty discriminating high-frequency sounds and speech clarity is characteristic of sensorineural hearing loss due to inner ear or auditory nerve damage. Other options (improvement with loud speech, Weber test findings, tympanic membrane changes) are more typical of conductive hearing loss or other conditions.
심화 해설
Core Nursing ExplanationKey Concept Analysis: This question tests the ability to differentiate between Conductive hearing loss and Sensorineural hearing loss (SNHL). The core theme is identifying the classic subjective complaint associated with SNHL, which involves damage to the inner ear (cochlea) or the auditory nerve (cranial nerve VIII). This damage impairs the ability to transduce sound vibrations into neural signals and to discriminate speech sounds, especially in challenging listening environments.
Answer Rationale: Key Point! Option ④ is correct because it directly describes the hallmark of sensorineural hearing loss. Damage to the hair cells in the cochlea, particularly those responsible for high-frequency sounds, leads to difficulty hearing consonants (like s, f, th) which are high-pitched. This results in the classic complaint: "I can hear you, but I can't understand you." The patient's own statement in the question, "I can't understand what they're saying, especially in noisy places," perfectly aligns with this. Background noise further masks the already unclear speech sounds, making comprehension nearly impossible.
Distractor Analysis:
Watch out for confusion! Option ①, "Hearing improves when speaking loudly," is characteristic of conductive hearing loss. In conductive loss, sound is blocked from reaching the inner ear (e.g., by earwax, fluid, or a perforated eardrum). Turning up the volume (increasing sound intensity) can overcome this mechanical blockage. In SNHL, louder speech may become distorted and uncomfortable (recruitment phenomenon) but does not improve clarity.
Option ②, "Bone conduction is greater than air conduction on Weber test," indicates conductive hearing loss. In a normal Weber test, sound is heard equally in both ears. If sound lateralizes (is heard better) to the ear with a problem, it suggests a conductive loss in that ear because bone conduction bypasses the outer/middle ear blockage. In SNHL, sound would lateralize to the better ear.
Option ③, "Tympanic membrane appears red and bulging," is a sign of acute otitis media, which causes a temporary conductive hearing loss due to fluid and pressure behind the eardrum. It is not a feature of the gradual, progressive sensorineural loss described.
Related Concepts: Presbycusis (age-related hearing loss) is the most common form of sensorineural hearing loss in older adults and typically begins with high-frequency loss. Nursing care focuses on effective communication strategies: facing the patient, speaking clearly at a moderate pace, reducing background noise, and using assistive devices.
임상 시나리오
Nursing Clinical Practice GuideClinical Scenario: You are a nurse in a primary care clinic. Mr. Johnson, a 70-year-old retired teacher, comes in with his daughter. She reports he has been increasingly withdrawn at family gatherings, often answering questions inappropriately, and has turned the television volume very high. Mr. Johnson seems frustrated and says, "Everyone mumbles these days."
Nursing Intervention Strategy:
1. Assessment: Perform a focused history. Use the WHHHIMP mnemonic for sudden hearing loss (Wax, Head trauma, Infection, etc.), but here, note the gradual onset. Ask about difficulty with phone conversations, hearing in restaurants, and tinnitus (ringing in the ears). Observe for non-verbal cues of hearing difficulty (leaning forward, cupping ear).
2. Communication: Implement immediate strategies. Get his attention before speaking, face him directly with good light on your face for lip-reading, speak clearly without shouting, and use short, simple sentences. Confirm understanding by asking him to repeat back instructions.
3. Collaboration & Education: Prepare the patient for a referral to an audiologist for formal hearing evaluation (audiogram). Educate about the likely diagnosis of presbycusis and the benefits of hearing aids. Discuss assistive listening devices for the TV and telephone.
Patient Safety and Precautions: Hearing loss is a major safety risk. It can lead to failure to hear alarms, smoke detectors, oncoming vehicles, or verbal warnings. It is also a significant risk factor for social isolation, depression, and cognitive decline. Always ensure the patient understands medication instructions by using written materials.
Nursing Procedure & Medication Flow
While there is no direct medication procedure for SNHL, nurses play a key role in the process:
Pre-Referral: Explain the purpose of the audiology exam. Remove any visible cerumen (earwax) if present and ordered, as this can mimic or exacerbate hearing loss.
Post-Diagnosis: If hearing aids are prescribed, educate on proper insertion, cleaning, battery management, and realistic expectations (they amplify sound but may not fully restore clarity, especially in noise).
Ototoxic Medication Monitoring: Be aware of drugs that can cause or worsen SNHL (e.g., aminoglycoside antibiotics like gentamicin, loop diuretics like furosemide, high-dose aspirin, certain chemotherapy agents). Monitor for tinnitus or subjective hearing changes in patients on these drugs.
A Word from Your Senior Nurse
Remember, hearing loss is often an "invisible" disability. A patient who seems confused, non-compliant, or irritable may actually be struggling to hear. Your skilled assessment to differentiate between conductive and sensorineural loss guides the entire care pathway. In clinical practice, taking an extra moment to ensure effective communication isn't just kindness—it's a critical nursing intervention that ensures safety, promotes autonomy, and preserves dignity. On the NCLEX, they are testing your foundational knowledge to make these crucial distinctions.
핵심 개념
Sensorineural Hearing Loss — Hearing loss caused by damage to the inner ear (cochlea) or the nerve pathways from the inner ear to the brain. Characterized by difficulty understanding speech, especially in noisy environments, and loss of high-frequency sounds.
Presbycusis — Age-related, progressive, bilateral sensorineural hearing loss. It typically begins with a loss of high-frequency sounds and is the most common cause of hearing loss in older adults.
Conductive Hearing Loss — Hearing loss caused by a problem conducting sound waves through the outer ear, tympanic membrane, or middle ear (ossicles). Sound is blocked from reaching the inner ear. Volume is the primary issue.
Weber Test — A tuning fork test used to differentiate between conductive and sensorineural hearing loss. The vibrating fork is placed on the midline of the skull. In conductive loss, sound lateralizes (is heard louder) to the affected ear. In sensorineural loss, it lateralizes to the better ear.
Ototoxicity — The property of being toxic to the ear (oto-), specifically the cochlea or auditory nerve, and sometimes the vestibular system. Can lead to sensorineural hearing loss, tinnitus, and balance disorders. Common with aminoglycosides, loop diuretics, and chemotherapy agents.
