Which nursing intervention is most appropriate for this client in the preoperative period? A 45-year-old client with mixed hearing loss is admitted for a stapedectomy procedure. The client reports progressive hearing loss over the past 5 years and difficulty hearing conversations in noisy environments. ## 보기 1. Encourage the client to blow their nose gently to clear any congestion 2. Administer prescribed ear drops to soften cerumen before surgery 3. Instruct the client to avoid blowing their nose or sneezing forcefully **✔ 정답** 4. Position the client on the affected side to promote drainage **정답: 3** ## 해설 Avoiding forceful nose blowing or sneezing prevents increased middle ear pressure that could compromise surgical outcomes in stapedectomy. Other options (encouraging nose blowing, administering ear drops, or positioning on affected side) are contraindicated as they may increase risk or are not preoperative priorities. ## 심화 해설 Preoperative Nursing Priority for Stapedectomy The most appropriate preoperative intervention is to instruct the client to avoid blowing their nose or sneezing forcefully. This directive is critical for preventing complications related to the anatomical and surgical principles of a stapedectomy. Rationale and Pathophysiology A stapedectomy is a microsurgical procedure performed to treat hearing loss, most commonly due to otosclerosis. In this condition, abnormal bone remodeling fixes the stapes bone to the oval window, preventing sound transmission to the inner ear. During the surgery, all or part of the fixed stapes is removed and replaced with a prosthesis. This creates a direct communication between the middle ear and the perilymph-filled inner ear vestibule. The primary immediate postoperative risk is the displacement of this delicate prosthesis or the development of a perilymphatic fistula. Any action that dramatically increases pressure in the middle ear or nasopharynx can be transmitted through the eustachian tube to the middle ear, potentially dislodging the prosthesis or forcing air and pathogens into the inner ear. Forceful nose blowing or sneezing with a closed mouth generates a significant Valsalva maneuver, creating precisely this dangerous pressure gradient. Preoperative teaching is essential so the client understands and practices open-mouth sneezing and avoids nose blowing before the procedure even begins, establishing the behavioral pattern for the critical postoperative period [1,2]. Analysis of Incorrect Options - Option 1: Encourage the client to blow their nose gently to clear any congestion. This is contraindicated. Even "gentle" nose blowing increases nasopharyngeal pressure, which can be transmitted to the middle ear. The goal is to avoid any pressure changes across the tympanic membrane and oval window. If the client has significant nasal congestion preoperatively, the surgeon must be notified, as the procedure may need to be postponed. - Option 2: Administer prescribed ear drops to soften cerumen before surgery. This is not a standard preoperative intervention for a stapedectomy. While a clean external auditory canal is necessary for surgical access, cerumen removal is performed carefully by the surgeon under direct visualization, not with cerumenolytic drops. Instilling any liquid into the ear canal in the presence of a potential tympanic membrane perforation or unknown middle ear status is unsafe without a direct order and specific indication. - Option 4: Position the client on the affected side to promote drainage. This position is incorrect and potentially harmful. Postoperatively, the client is typically positioned with the operated ear up to prevent pressure on the surgical site and to keep the prosthetic in place. The concept of "promoting drainage" is not a primary goal after a stapedectomy, as the middle ear is a closed, sterile space, and excessive drainage would indicate a complication like a cerebrospinal fluid leak or infection. The surgical site often contains packing that should remain undisturbed. The Swedish national register study on stapes surgery highlights the systematic collection of surgical and audiological outcomes, emphasizing the importance of meticulous perioperative care to achieve optimal results and prevent complications that could compromise hearing restoration [1]. The comparative study on stapedotomy and stapedectomy further reinforces that surgical success relies on the stability of the reconstructed ossicular chain, which is directly threatened by pressure-altering activities [2].References (research sources) - [1]Stapes surgery in Sweden: evaluation of a national-based register.Research articleStrömbäck K, Lundman L, Bjorsne A, Grendin J, Stjernquist-Desatnik A, Dahlin-Redfors Y.

(2013) · DOI: 10.5001/omj.2013.08 ## 임상 시나리오 Preoperative Stapedectomy Patient EducationPreventing Prosthesis Displacement and Inner Ear Injury The priority teaching is to avoid any action that increases middle ear pressure. The client must be instructed to avoid blowing their nose and to sneeze or cough with the mouth open. This prevents a Valsalva maneuver, which transmits pressure through the eustachian tube and can dislodge the delicate prosthesis or create a perilymphatic fistula. CautionThis restriction is lifelong for some patients and must be strictly followed in the immediate postoperative period. Educate the patient to keep their mouth open during a sneeze to dissipate the pressure wave safely. ## 핵심 개념 - **Stapedectomy** — Microsurgical removal of a fixed stapes bone and replacement with a prosthesis to restore sound conduction in the middle ear. - **Perilymphatic Fistula** — An abnormal communication between the middle ear and the perilymph-filled inner ear, often caused by pressure changes or trauma, leading to vertigo and hearing loss. - **Otosclerosis** — A condition of abnormal bone remodeling in the middle ear that fixes the stapes to the oval window, causing conductive hearing loss. - **Valsalva Maneuver** — Forced expiration against a closed airway, which increases intrathoracic and nasopharyngeal pressure, transmitted to the middle ear via the eustachian tube. ## 같은 주제 문제 - [A nurse is assessing a 70-year-old client with suspected mixed hearing loss.
