A client with metastatic cancer reports a pain level of 10 on a scale of 0 to 10. Twenty minutes after the nurse administers an IV analgesic, the client reports no pain relief. Which intervention is most important for the nurse to include in this client's plan of care?

A. One of the most common triggers is a distended bladder. When the bladder becomes full, it sends signals to the spinal cord, but due to the injury, these signals are unable to pass beyond the level of injury. This results in uncontrolled sympathetic activation, leading to symptoms such as hypertension, sweating, and headache.
B. Forehead diaphoresis, or sweating, is a potential symptom of autonomic dysreflexia. However, it is more of a consequence rather than a precipitating factor. It occurs as a result of sympathetic nervous system activation in response to the triggering stimulus.
C. Skeletal traction misalignment is not a common precipitating factor for autonomic dysreflexia. Autonomic dysreflexia is typically triggered by stimuli related to visceral or autonomic reflexes, such as bladder distention or bowel impaction, rather than mechanical issues like traction misalignment.
D. A severe pounding headache can occur as a symptom of autonomic dysreflexia, but it is not the primary precipitating factor. The headache is a result of the sudden increase in blood pressure that occurs during autonomic dysreflexia.

D. Vital sign measurements, including blood pressure, heart rate, respiratory rate, and temperature, are essential for assessing the client's hemodynamic stability and overall condition. A rigid abdomen with rebound tenderness suggests a potential surgical emergency, such as bowel perforation, which could lead to sepsis and hemodynamic instability. Therefore, obtaining vital sign measurements promptly will help determine the severity of the client's condition and guide further interventions.
A. Encouraging ambulation would not be appropriate in this situation because it could exacerbate the client's discomfort and potentially worsen any abdominal pain or tenderness. Ambulation is not the priority when a client presents with signs of a possible bowel perforation.
B. Measure capillary glucose level: While monitoring blood glucose levels is important, especially in clients receiving corticosteroid treatment, it is not the priority when the client is presenting with symptoms suggestive of a serious complication such as bowel perforation. Immediate assessment and intervention to address the abdominal rigidity and rebound tenderness are needed before other assessments can be performed.
C. While bloody stools are a common symptom of IBD exacerbation, the presence of a rigid abdomen with rebound tenderness suggests a more urgent issue, such as bowel perforation, that requires immediate attention. Monitoring for bloody stools should occur concurrently with assessing and managing the client's acute abdominal symptoms.
