A nurse is preparing a client for a colonoscopy. While monitoring a client, which of the described clinical findings is the priority for HCP notification?

Difficulty swallowing liquids indicates severe dysphagia and aspiration risk, which is critical to report before colonoscopy due to sedation and positioning risks. Other findings (mild hypertension, tachycardia, low-grade fever) are common and less urgent.

Understanding the Priority Assessment During Colonoscopy Preparation

The correct answer is Difficulty swallowing liquids. In the context of preparing a client for a colonoscopy, the nurse must apply the airway, breathing, and circulation (ABC) framework to prioritize clinical findings. While the other options represent variations in vital signs that require monitoring, they do not signal an immediate threat to a patent airway.

Why Difficulty Swallowing is the Priority
Dysphagia, or difficulty swallowing, is a critical neurological sign that can indicate an evolving cerebrovascular event, such as a stroke, or a neuromuscular disorder. The immediate danger is the high risk of aspiration, which compromises the airway. Aspiration of liquids can rapidly lead to airway obstruction, chemical pneumonitis, or aspiration pneumonia, all of which are life-threatening emergencies. This directly aligns with the "A" (Airway) in the ABC priority-setting framework, making it the finding that requires the most urgent notification to the healthcare provider (HCP). The clinical significance of aspiration risk is well-documented in endoscopic procedures. A retrospective study on gastrointestinal debris retention during endoscopy found that the presence of retained material can lead to aborted procedures, unplanned intubation, and aspiration . If retained gastric contents pose such a significant risk, a client’s active inability to protect their own airway by swallowing is an even more immediate pre-procedural crisis.

Analysis of Other Findings
The other vital sign changes, while important to note, are common physiological responses to stress, pain, or the underlying condition and do not represent an immediate airway threat.

- Blood pressure of 142/88 mmHg: This reading indicates Stage 1 hypertension. Pre-procedural anxiety and pain are well-known causes of elevated blood pressure. A randomized controlled trial on patients undergoing colonoscopy demonstrated that managing pre-procedural anxiety and stress is a key focus because these psychological factors directly influence hemodynamic stability, including blood pressure . While this finding requires documentation and continued monitoring, it does not supersede an airway concern.
- Heart rate of 92 beats per minute: This is a mild sinus tachycardia, falling just above the normal adult range. Like hypertension, it is a predictable physiological response to anxiety, pain, or mild dehydration from bowel preparation. The same trial on procedural anxiety confirmed that interventions aimed at reducing stress can help stabilize heart rate, highlighting its link to a client's psychological state rather than an acute decompensation . It is a finding to be assessed in context, not a standalone emergency.
- Temperature of 99.2°F (37.3°C): This is a low-grade fever. In a client with persistent abdominal pain and changes in bowel habits, a slight temperature elevation could be related to the underlying inflammatory or neoplastic process being investigated. It does not represent an immediate threat to the client’s airway, breathing, or circulation and can be reported as part of the overall clinical picture after the priority concern is addressed.

Clinical Reasoning and Test-Taking Strategy
For NCLEX-RN priority questions, always apply the ABC framework. A finding that suggests a potential loss of airway protection (difficulty swallowing) is always a higher priority than stable or mildly abnormal vital signs. The nurse’s immediate action is to recognize that a new onset of dysphagia is a neurological red flag that puts the client at immediate risk for aspiration, necessitating prompt HCP notification before the procedure proceeds. The other options, while requiring nursing assessment and intervention, are secondary to securing the airway.
