Which nursing intervention should the nurse implement first? ## 보기 1. Instill mineral oil drops into the affected ear **✔ 정답** 2. Irrigate the ear canal with warm saline solution 3. Use a cotton-tipped applicator to remove the cerumen 4. Refer the client immediately to an otolaryngologist **정답: 1** ## 해설 The priority intervention for impacted cerumen is to soften the wax with mineral oil drops first, as this makes removal safer and more effective. Other options like irrigation or cotton swabs can cause trauma if done before softening. ## 심화 해설 Understanding Cerumen Impaction Cerumen, or ear wax, is a normal bodily secretion that serves a protective function and is part of the ear's self-cleaning mechanism. It is usually naturally expelled from the ear canal. When this mechanism fails, wax is retained and can become impacted cerumen, obstructing the ear canal and causing symptoms such as hearing loss, a feeling of fullness, or pain [2]. The initial management approach is crucial for safe and effective resolution. Prioritizing the First Intervention The first-line intervention for a client with impacted cerumen is to soften the wax. This is achieved by instilling cerumenolytic or softening agents, such as mineral oil drops, into the affected ear [1]. This approach is prioritized because it is non-invasive, prepares the cerumen for easier and safer removal, and can often resolve the impaction on its own without further procedures. The rationale is to hydrate and break down the hardened wax mass, which reduces the risk of trauma to the ear canal or tympanic membrane during any subsequent removal attempts. Analysis of Incorrect Options - Option 2: Irrigate the ear canal with warm saline solution. Irrigation is a common method for cerumen removal, but it should not be the first step. If the cerumen is hard and dry, the pressure from irrigation can be painful and may fail to dislodge the plug. More critically, performing irrigation without a confirmed intact tympanic membrane can lead to serious complications. Softening the wax first with drops makes irrigation significantly safer and more effective [1]. - Option 3: Use a cotton-tipped applicator to remove the cerumen. This is a contraindicated and dangerous practice. Inserting a cotton-tipped applicator into the ear canal can push the cerumen deeper, worsening the impaction, and can traumatize the delicate skin of the canal or perforate the tympanic membrane. It is never a recommended nursing intervention for impacted cerumen. - Option 4: Refer the client immediately to an otolaryngologist. While referral to a specialist is appropriate for complex cases or when initial management fails, it is not the required first action. Cerumen removal is one of the most common procedures performed in primary care, and initial management with ear drops is well within the scope of nursing practice based on established protocols [1, 3]. Immediate referral without attempting first-line softening is an unnecessary escalation of care. The foundational step in managing impacted cerumen is to soften the wax with an appropriate agent like mineral oil, which facilitates the ear's natural expulsion mechanism and prepares the canal for safe irrigation if it becomes necessary [2].References (research sources) - [1]Cerumen Management: An Updated Clinical Review and Evidence-Based Approach for Primary Care Physicians.Research articleHorton GA, Simpson MTW, Beyea MM, Beyea JA.

Verify there is no history of tympanic membrane perforation, recent ear surgery, or active ear infection. Document baseline hearing status. First-Line Intervention: Cerumen Softening Instill 2-3 drops of mineral oil, baby oil, or commercial cerumenolytic (e.g., carbamide peroxide) into the affected ear. Position the client with the affected ear upward for 5-10 minutes to allow the agent to penetrate. Repeat 2-3 times daily for 3-5 days. This softens the wax and may resolve the impaction spontaneously. Subsequent Removal Options If softening alone is insufficient, gentle irrigation with warm (body temperature) water or saline may be performed using a bulb syringe or electronic irrigator. Direct the stream along the canal wall, not directly at the tympanic membrane. Manual removal with a curette or suction is reserved for trained clinicians using an otoscope for direct visualization. Safety Precautions and Contraindications Never use cotton-tipped applicators or sharp objects, as they can push wax deeper or perforate the tympanic membrane. Do not irrigate if the tympanic membrane is not intact, if the client has diabetes (higher infection risk), or if there is a history of otitis externa. Refer to an otolaryngologist if impaction persists after first-line measures, if severe pain or drainage develops, or if the client has a narrow or abnormal ear canal. ## 핵심 개념 - **Cerumen** — A normal protective secretion of the ear canal that can become impacted, causing obstruction and symptoms like hearing loss. - **Cerumenolytic** — An agent such as mineral oil that softens and breaks down ear wax to facilitate its removal. - **Impacted Cerumen** — Accumulated ear wax that obstructs the ear canal, often requiring intervention to relieve symptoms. - **Tympanic Membrane** — The eardrum; its integrity must be confirmed before performing ear irrigation to prevent serious complications. ## 같은 주제 문제 - [A nurse is assessing a 45-year-old patient who reports decreased hearing and a feeling of …](https://mymerci.kr/pages/nclex_q.php?qn_id=541727) - [A nurse is assessing a patient who reports decreased hearing and ear fullness.
