diverticulosis - Nursing Case Study
Pathophysiology
• Primary mechanism: Diverticulosis occurs primarily due to increased intraluminal pressure in the colon, which leads to the formation of small pouches or diverticula. This pressure buildup is often a result of low-fiber diets, causing harder stools and increased colonic contractions during bowel movements.
• Secondary mechanism: Weakness in the muscular layer of the colon wall, particularly in areas where blood vessels penetrate, facilitates the formation of these diverticula. Aging and connective tissue changes exacerbate this weakness, making the colon more susceptible to diverticula development.
• Key complication: Although often asymptomatic, diverticulosis can lead to diverticulitis if a diverticulum becomes inflamed or infected. This can cause significant abdominal pain, fever, and digestive disturbances, requiring medical intervention to prevent further complications like perforation or abscess formation.

Section 1
As the nursing team continues to monitor the 56-year-old female patient, there is a noticeable change in her clinical status that prompts further investigation. Over the next 24 hours, her abdominal pain intensifies, particularly in the left lower quadrant, and her fever escalates to 101.4°F. The patient's blood pressure remains elevated at 150/92 mmHg, and her pulse has increased to 104 bpm. She reports increasing nausea and has begun to have more difficulty passing stool, with her bowel movements becoming more painful and less frequent.
A complete blood count (CBC) is drawn, and the results reveal a white blood cell count of 14,500/mm³, indicating a possible infection or inflammatory process. A C-reactive protein (CRP) test shows elevated levels, further suggesting systemic inflammation. Given these findings, the healthcare team considers the development of diverticulitis as a complication of her existing diverticulosis. The patient is prepared for an abdominal CT scan to confirm the presence of inflammation or any other complications such as an abscess or perforation.
In response to the suspected diagnosis of diverticulitis, the clinical team initiates a treatment plan that includes starting the patient on a course of broad-spectrum antibiotics to address potential bacterial infection. Pain management is also prioritized, with analgesics provided to alleviate her discomfort. The team discusses the importance of bowel rest, advising the patient to follow a clear liquid diet as her gastrointestinal tract stabilizes. These interventions are closely monitored to assess their effectiveness and to determine if any further escalation of care is necessary.
Section 2
As the treatment plan is implemented, the nursing team continues to closely monitor the patient's status for any changes. Over the next 48 hours, there is a noticeable improvement in some of her symptoms. The patient's fever has reduced to 99.8°F, and her abdominal pain, although still present, has become more manageable with the prescribed analgesics. Her nausea has decreased, and she reports being able to tolerate the clear liquid diet without any significant issues. However, her bowel movements remain infrequent, and she continues to experience some discomfort during defecation.
Despite these improvements, the patient's blood pressure remains elevated at 148/90 mmHg, and her pulse, while slightly lower, is still elevated at 98 bpm. A repeat CBC shows that her white blood cell count has decreased to 13,000/mm³, indicating that the antibiotic therapy may be effective in addressing the infection. However, the CRP levels remain elevated, suggesting ongoing inflammation. The abdominal CT scan results confirm the presence of diverticulitis with localized inflammation but rule out any abscess formation or perforation, which reassures the team that there are currently no severe complications.
Given these findings, the clinical team decides to continue with the current treatment regimen but emphasizes the need for ongoing monitoring of the patient's vital signs, pain levels, and bowel function. The importance of maintaining bowel rest and gradually advancing the diet as tolerated is reiterated to the patient. Additionally, the team considers the potential need for further interventions, such as surgical consultation, should there be no significant improvement or if any new complications arise. This vigilance in monitoring and response ensures that the patient receives timely and appropriate care as her condition progresses.
Section 3
On the morning of the third day, the nursing team observes a change in the patient's status that warrants further investigation. The patient reports an increase in her abdominal pain, now rating it as a 7 out of 10 on the pain scale, compared to the previous 4 out of 10. She also describes the pain as sharper and more localized to the lower left quadrant. Additionally, the patient experiences a slight increase in nausea, though she continues to tolerate the clear liquid diet. Her vital signs reveal a mild increase in her temperature to 100.2°F, while her blood pressure has risen to 152/92 mmHg, and her heart rate is now 104 bpm.
Given these changes, the clinical team orders a repeat abdominal CT scan to reassess the situation. The new imaging results reveal a small pericolic abscess, a complication of diverticulitis that was not present in the initial scans. This finding explains the increased pain and subtle changes in her clinical presentation. The presence of the abscess indicates a progression in her condition, necessitating a shift in the treatment approach.
The medical team discusses potential interventions, including percutaneous drainage of the abscess, to prevent further complications. Antibiotic therapy is adjusted to target the specific pathogens identified in the abscess culture, and the patient is educated on the importance of adhering to the modified treatment plan. The nursing staff intensifies their monitoring, focusing on signs of sepsis or further deterioration, while providing support and reassurance to the patient and her family, outlining the next steps in her care plan. This development underscores the need for vigilant monitoring and adaptability in managing diverticulitis complications.
Section 4
As the patient continues under close observation, the nursing team notes further changes in her condition that suggest a shift in her clinical status. On the afternoon of the fourth day, the patient begins to exhibit signs of increasing discomfort, despite the initiation of targeted antibiotic therapy. Her abdominal pain intensifies, now described as an 8 out of 10, and remains sharply localized to the lower left quadrant. The nursing staff also observes that her abdomen is becoming more distended and firm upon palpation, raising concerns about potential complications. Additionally, the patient reports feeling more fatigued and slightly short of breath, although her oxygen saturation remains stable at 94% on room air.
Vital signs reveal a concerning trend: her temperature has risen further to 101.3°F, her blood pressure remains elevated at 158/96 mmHg, and her heart rate has increased to 112 bpm. These changes, coupled with the patient's increased pain and new abdominal findings, prompt the clinical team to suspect early signs of sepsis or the possibility of the abscess expanding or rupturing. Laboratory results show a rising white blood cell count, now at 14,500/mm³, with a left shift indicating a heightened inflammatory response.
In response to these developments, the medical team decides to expedite the percutaneous drainage of the abscess, hoping to alleviate the patient's symptoms and prevent further complications. The patient is prepared for the procedure, with the nursing staff providing detailed education and emotional support to both the patient and her family. They emphasize the importance of the intervention in managing the abscess and preventing escalation to severe sepsis or peritonitis. The team remains vigilant, ready to adjust the treatment plan based on the patient's response to the drainage and ongoing assessments, ensuring a comprehensive and dynamic approach to her care.
Section 5
Following the percutaneous drainage procedure, the nursing team closely monitors the patient's status, paying particular attention to her vital signs, pain levels, and overall comfort. Initially, the patient appears to experience some relief, with her abdominal pain decreasing to a 5 out of 10. However, within the next 24 hours, her condition begins to show unexpected changes that prompt further clinical evaluation. The patient's abdomen remains distended, and there is new onset of guarding and rebound tenderness, suggesting the possibility of peritoneal involvement.
Vital signs indicate that her temperature has only marginally decreased to 100.8°F, while her heart rate remains elevated at 110 bpm. Her blood pressure, meanwhile, has dropped to 140/88 mmHg, indicating a possible shift in her hemodynamic status. The nursing team notes that the patient's oxygen saturation has decreased slightly to 92% on room air, and she continues to report feeling fatigued and short of breath. These findings raise concerns about potential complications such as evolving peritonitis or a secondary infection.
A repeat abdominal CT scan is ordered to evaluate the current status of the abscess and check for any signs of perforation or peritoneal involvement. The results reveal partial drainage of the abscess but also indicate a small amount of free air in the peritoneal cavity, consistent with a micro-perforation. This new finding necessitates a change in the clinical approach, prompting the medical team to consider surgical consultation and potential escalation in the patient's antibiotic regimen. The nursing team prepares to implement these new orders, focusing on stabilizing the patient's condition and preventing further deterioration.
