Which nursing intervention should be the priority? ## 보기 1. Apply warm compresses to the affected ear every 2 hours 2. Encourage the patient to lie on the unaffected side 3. Administer prescribed analgesics for pain management 4. Monitor for signs of neurological complications **✔ 정답** **정답: 4** ## 해설 Monitoring for neurological complications is the priority due to the risk of intracranial spread from mastoiditis, which can lead to life-threatening conditions like meningitis or brain abscess. Other interventions like pain management or positioning are secondary. ## 심화 해설 Understanding the Priority: Why Neurological Monitoring Comes First When caring for a patient with acute mastoiditis, the nurse must recognize that this infection involves the mastoid bone, which is part of the temporal bone of the skull. The anatomical proximity of the mastoid air cells to the brain and its protective coverings (meninges) means the infection can erode through the thin bony plates separating the ear from the cranial cavity. This is not simply a localized ear infection; it is a potential neurosurgical emergency. Therefore, while all the listed interventions are components of care, the nursing process dictates that the priority is assessing for and detecting the most life-threatening complications first. The primary danger in acute mastoiditis is the intracranial extension of the infection, which can manifest as meningitis, brain abscess, or cerebral venous sinus thrombosis (CVST) [3]. Anatomical Basis for Intracranial Spread The mastoid air cells are located posterior to the middle ear and are separated from the posterior and middle cranial fossae by only a thin layer of bone. Infection can spread directly through this bone, via preformed pathways like vascular channels, or through the labyrinth of the inner ear. Once the infection breaches these barriers, it can lead to severe neurological conditions. The provided evidence consistently highlights this risk. One case report describes a child whose acute mastoiditis worsened despite antibiotic therapy, leading to the development of headache, neck stiffness, and drowsiness—classic signs of meningeal irritation that necessitated a lumbar puncture and a change in management to target central nervous system involvement [3]. Another report details an adult patient who presented with acute confusion, fever, agitation, and neck stiffness, where CT imaging confirmed mastoiditis and a rare complication called pneumocephalus (air within the cranial cavity), which served as a direct clue to underlying bacterial meningitis [4]. The Danger of Masked Mastoiditis The priority of neurological assessment is further underscored by the phenomenon of "masked mastoiditis." This presentation, particularly dangerous in elderly or immunocompromised patients, occurs when the classic otological signs like ear pain, a bulging tympanic membrane, or post-auricular swelling are absent or minimal. As one study illustrates, an elderly patient with no overt ear findings on initial otoscopy was discharged with a presumed viral illness, only to return days later with acute neurological deterioration from pneumococcal meningoencephalitis originating from an unrecognized mastoid infection [1]. This demonstrates that a normal-appearing ear does not rule out the progression of mastoiditis to a life-threatening intracranial infection. The nurse's ongoing, focused neurological assessment is the safety net that can detect these subtle, early changes in a patient's level of consciousness, pupillary response, or development of nuchal rigidity. Clinical Application of the Nursing Process In applying the nursing process, assessment is the first and foundational step. For a patient with acute mastoiditis, the assessment with the highest stakes is the neurological exam. The nurse must vigilantly monitor for early indicators of central nervous system involvement, which include: * A change in level of consciousness, such as new-onset confusion or drowsiness [3,4]. * The development of a severe headache [3]. * Signs of meningeal irritation, specifically neck stiffness [3,4]. * Cranial nerve palsies, which may indicate a focal abscess formation. While administering prescribed analgesics (Option 3) is important for comfort, and applying warm compresses (Option 1) may provide some local symptomatic relief, these are comfort-focused interventions. Encouraging the patient to lie on the unaffected side (Option 2) can promote drainage, but it is a lower-priority action. These interventions are secondary to the critical task of recognizing a deteriorating patient. Failure to detect early neurological signs can lead to a catastrophic delay in treatment, as the management of a simple mastoiditis with intravenous antibiotics is vastly different from the emergent neurosurgical intervention and intensive care required for a patient with meningitis, CVST, or a brain abscess [3,4]. The nurse’s role is to identify these changes immediately and escalate care to prevent irreversible neurological damage or death.References (research sources) - [1]Masked Mastoiditis Presenting As Pneumococcal Meningoencephalitis in an Elderly Patient: A Diagnostic Pitfall in the Emergency Department.Research articleBandera-Flores CM, Zalba-Etayo B, Bergua-Díez V, Lahoza-Pérez MDC, Sáenz-Abad D.

(2026) · DOI: 10.7759/cureus.103191 ## 임상 시나리오 Neurological Monitoring in MastoiditisDetecting Intracranial Extension Early The priority nursing intervention for acute mastoiditis is frequent neurological assessment. The infection can erode the thin temporal bone, leading to intracranial complications like meningitis or brain abscess. Monitor vital signs and neurological status at least every 4 hours. Assess for changes in level of consciousness, severe headache, photophobia, nuchal rigidity, and focal motor deficits. Report any decline immediately. CautionPain medication can mask an early headache from increased intracranial pressure. Always perform a full neurological exam before administering analgesics to avoid missing a critical change in status. ## 핵심 개념 - **Mastoiditis** — A bacterial infection of the mastoid air cells in the temporal bone, often a complication of otitis media, with risk of intracranial extension. - **Intracranial Complications** — Life-threatening conditions such as meningitis, brain abscess, or cerebral venous sinus thrombosis resulting from the spread of infection from the mastoid to the cranial cavity. - **Nursing Priority** — The intervention that addresses the most urgent, life-threatening risk first, based on the ABCs and potential for rapid deterioration, in this case, neurological status. ## 같은 주제 문제 - [A nurse is assessing a 6-year-old child with suspected mastoiditis.
