Blood pressure 128/82 mmHg **정답: 1** ## 해설 Loose dental work poses the highest safety risk as it can dislodge during endoscopy, causing airway obstruction or aspiration. Mild anxiety, NPO compliance, and normal BP are manageable with standard care. ## 심화 해설 Clinical Context & Priority Setting During pre-procedure assessment for urgent upper endoscopy with sedation, the nurse must apply the ABC (Airway, Breathing, Circulation) priority framework. Sedation induces a continuum of central nervous system depression, which predictably diminishes protective airway reflexes and can lead to upper airway obstruction. The highest priority is any factor that threatens airway patency once the patient is sedated. Why Loose Dental Work Is the Highest Priority Loose dental work presents a direct and mechanical threat to the airway. During upper endoscopy, the endoscope is passed through the oropharynx, and sedation reduces pharyngeal muscle tone and the gag reflex. A dislodged tooth, crown, or bridge can become a foreign body, causing partial or complete airway obstruction, laryngospasm, or necessitating emergency retrieval—a scenario that is both life-threatening and procedurally disruptive. Addressing this finding before sedation involves documenting its location, notifying the endoscopist and anesthesia provider, and possibly securing or removing the loose hardware to create a safe airway environment. The foundational principle of sedation safety rests on anticipating and mitigating airway risks, as respiratory complications are the most common serious adverse events during endoscopic sedation [1,3]. Analysis of Other Options - Mild anxiety is an expected psychological response to an urgent invasive procedure. While it requires therapeutic communication and emotional support, it does not pose an immediate physiological threat to airway, breathing, or circulation. It is not the priority over a tangible airway hazard. - Last oral intake 8 hours ago meets the standard pre-procedure fasting guideline for solids (typically 6–8 hours) to minimize aspiration risk. This finding confirms the patient is adequately prepared regarding gastric emptying and does not require an intervention to delay the procedure. - Blood pressure 128/82 mmHg is a non-critical value. While sedation can cause hypotension, particularly in elderly patients with reduced cardiovascular reserve [2], this reading is normotensive and does not indicate hemodynamic instability that would take precedence over securing the airway. Pathophysiological & Safety Rationale The core of sedation risk is respiratory depression. Sedative agents like propofol or ciprofol cause a dose-dependent blunting of the hypercapnic and hypoxic ventilatory drives, along with relaxation of the genioglossus and other upper airway dilator muscles [2,4]. In this state, even a small foreign object becomes a critical obstruction. Monitoring technologies such as capnography are now recommended precisely because they detect early respiratory compromise (e.g., apnea, hypopnea) before pulse oximetry shows desaturation [3,4]. The nurse’s pre-procedure assessment is the first line of defense; identifying and neutralizing a mechanical airway threat like loose dental work directly prevents the hypoxic event that capnography would later detect. This aligns with the shift toward personalized, risk-stratified sedation pathways, where pre-procedural patient factors are systematically evaluated to tailor the sedation plan and enhance safety [1].References (research sources) - [1]Sedation in Gastrointestinal Endoscopy: From Drug-Centered Protocols to Personalized, Technology-Supported Pathways: A Narrative Review.Research articleBonura GF, Soriani P, Gualandi N, Cortegoso Valdivia P, Gabbani T, Parrella A, Koulaouzidis A, Manno M.

Sedation abolishes protective reflexes, and a dislodged object can cause complete airway obstruction or laryngospasm during endoscope passage. The nurse must document the specific location of the loose hardware, notify the endoscopist and anesthesia provider, and anticipate possible removal or securing before sedation to ensure a patent airway. CautionRespiratory depression and airway loss are the most common serious adverse events in endoscopic sedation. Never proceed without explicitly communicating dental risks to the procedural team. ## 핵심 개념 - **ABC Priority Framework** — A triage and assessment approach prioritizing Airway, Breathing, and Circulation to identify and manage the most life-threatening conditions first. - **Sedation-induced airway compromise** — The predictable reduction in protective airway reflexes, pharyngeal muscle tone, and gag reflex caused by sedative medications, increasing the risk of obstruction or aspiration. ## 같은 주제 문제 - [A nurse is preparing a 72-year-old client with a history of stroke for an upper endoscopy …](https://mymerci.kr/pages/nclex_q.php?qn_id=540490) - [A nurse is preparing a client for a colonoscopy.
