Which nursing intervention should the nurse implement first? ## 보기 1. Instill mineral oil drops to soften the cerumen **✔ 정답** 2. Irrigate the ear canal with warm saline solution 3. Remove the cerumen using a cotton-tipped applicator 4. Refer the client immediately to an otolaryngologist **정답: 1** ## 해설 The priority is to soften impacted cerumen with mineral oil drops first, as it facilitates safe removal. Irrigation is a secondary step, cotton-tipped applicators are contraindicated, and referral is for refractory cases. ## 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.

Document onset and any prior self-treatment attempts. - **Otoscopic Examination:** If within scope of practice, visualize the ear canal to confirm a cerumen plug occluding the lumen. Note the color and consistency (hard, dry vs. soft). Never attempt blind instrumentation. - **History Taking:** Screen for contraindications to irrigation or cerumenolytics, such as a history of tympanic membrane perforation, recent ear surgery, or active ear infection. Stepwise Nursing Intervention - **First-Line: Cerumenolysis** - 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 drops to penetrate the cerumen mass. - Instruct the client to use drops twice daily for 3-5 days to adequately soften the impaction before attempting removal. - **Second-Line: Irrigation (Only After Softening)** - Ensure the tympanic membrane is intact before proceeding. Use a bulb syringe or electronic irrigator with body-temperature water or saline. - Direct the stream gently toward the superior posterior wall of the ear canal, not directly at the tympanic membrane, to create a backwash effect. - Stop immediately if the client reports pain, dizziness, or if bleeding occurs. - **Third-Line: Instrumentation (By Trained Personnel Only)** - Manual removal using a curette, hook, or suction under direct visualization is reserved for trained advanced practice nurses or physicians. - Cotton-tipped applicators are strictly contraindicated as they push cerumen deeper and risk epithelial trauma or perforation. Client Education and Prevention - **Avoid Self-Cleaning with Objects:** Reinforce that the ear is self-cleaning and inserting cotton swabs, bobby pins, or other objects causes impaction and injury. - **Home Maintenance:** For clients with recurrent impaction, recommend routine use of a few drops of mineral oil weekly to maintain cerumen softness and promote natural migration. - **Follow-Up:** Advise the client to return for evaluation if symptoms persist after a full course of softening drops and gentle irrigation, as this may indicate a deeper impaction or other pathology requiring specialist referral. ## 핵심 개념 - **Cerumen Impaction** — Accumulation of earwax in the external auditory canal causing symptoms like hearing loss, fullness, or pain, often requiring softening before removal. - **Cerumenolysis** — The process of using cerumenolytic agents like mineral oil to hydrate and break down the keratin and lipid components of earwax, reducing its cohesion. - **Least Invasive Intervention** — A nursing principle prioritizing the gentlest, safest method first to minimize patient harm, such as using ear drops before irrigation or instrumentation. - **Mineral Oil** — A common, inert cerumenolytic agent used to soften hardened earwax, facilitating natural expulsion or safer mechanical removal. - **Tympanic Membrane** — A thin membrane separating the external ear from the middle ear, vulnerable to perforation from improper ear cleaning techniques like irrigation or cotton swabs. ## 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.
