GI bleeding - Nursing Case Study

Pathophysiology

• Primary mechanism: Damage to the gastrointestinal (GI) tract lining, such as ulcers or tears, can lead to bleeding. This damage is often caused by stomach acid eroding the protective mucosal layer, which exposes blood vessels.

• Secondary mechanism: Inflammation or infection, such as from gastritis or diverticulitis, can weaken the tissue integrity of the GI tract and increase the risk of bleeding. This often results from bacterial infection or chronic irritation from substances like alcohol or NSAIDs.

• Key complication: If bleeding is significant, it can lead to anemia due to loss of red blood cells, reducing oxygen delivery to tissues and causing symptoms like fatigue and dizziness.

Initial Assessment Findings:

Upon further assessment, the nursing team conducted a focused gastrointestinal and hematologic evaluation. The patient reported that the abdominal discomfort was localized to the upper abdomen and was described as a dull ache that was intermittently present, particularly after meals. A focused abdominal examination revealed mild tenderness to palpation in the epigastric region, with no guarding or rebound tenderness noted. Bowel sounds were present and active in all four quadrants, suggesting normal intestinal activity.

To investigate the concern of potential bleeding, a stool guaiac test was performed and returned positive, confirming the presence of blood in the stool. Hemoglobin and hematocrit levels were obtained, showing a mild decrease with hemoglobin at 11.5 g/dL (normal range for males: 13.8 to 17.2 g/dL) and hematocrit at 35% (normal range for males: 41% to 50%), indicating a mild anemia likely due to chronic blood loss. The patient's vital signs remained stable with a blood pressure of 120/80 mmHg, heart rate of 78 bpm, respiratory rate of 16 breaths per minute, and oxygen saturation of 98% on room air, suggesting hemodynamic stability despite the noted anemia.

These assessment findings point toward a stable condition with a low risk of immediate complications; however, the mild anemia requires intervention to prevent progression. The nursing team plans to continue monitoring the patient's hematologic status, provide education on avoiding triggers that may exacerbate his peptic ulcer disease, and collaborate with the healthcare provider to consider potential adjustments in the patient's medication regimen, such as increasing the dose of the proton pump inhibitor to promote better control of gastric acid secretion.

Response to Interventions:

Following the initial assessment, the nursing team implemented a care plan aimed at addressing the patient's mild anemia and managing his peptic ulcer disease. The patient was educated on dietary modifications, such as avoiding spicy foods, caffeine, and alcohol, which could exacerbate his symptoms. Additionally, the patient's proton pump inhibitor (PPI) dosage was adjusted by the healthcare provider to enhance acid suppression and promote mucosal healing. The patient expressed understanding and willingness to adhere to these recommendations.

Over the next 48 hours, the patient's condition was closely monitored for any changes. Repeat hemoglobin and hematocrit levels were ordered to evaluate the effectiveness of the interventions. The results showed stabilization of hemoglobin at 11.8 g/dL and hematocrit at 36%, indicating a positive response to the treatment plan with no further decline in blood levels. The patient reported a decrease in episodes of abdominal discomfort and an overall improvement in well-being, suggesting effective symptom management.

Vital signs remained stable, with a blood pressure of 118/78 mmHg, heart rate of 76 bpm, respiratory rate of 16 breaths per minute, and oxygen saturation at 98% on room air. These findings supported the patient's hemodynamic stability and confirmed that the interventions were effectively preventing further complications. The nursing team continued to provide support and education, emphasizing the importance of adherence to medication and lifestyle changes to maintain control over the patient's condition and prevent future exacerbations. This stable status opened the path for the healthcare team to plan for potential discharge with appropriate follow-up care.

New Diagnostic Results:

As the patient continued to show signs of improvement, the healthcare team decided to perform an upper gastrointestinal endoscopy to assess the status of the peptic ulcer and ensure there were no active sources of bleeding. The procedure was scheduled and carried out smoothly, with the patient experiencing minimal discomfort. The endoscopy results revealed a healing duodenal ulcer with no active bleeding, confirming that the interventions were effective in promoting mucosal healing. The gastroenterologist noted mild inflammation in the gastric mucosa, which was consistent with the patient's history of peptic ulcer disease and likely related to past NSAID use. Biopsies were taken to rule out any infection with Helicobacter pylori, a common contributor to ulcer formation.

The biopsy results later returned negative for H. pylori infection, allowing the healthcare team to focus on managing the ulcer through continued medical therapy and lifestyle modifications. This result provided reassurance to both the patient and the healthcare team, as it eliminated the need for additional antibiotic therapy. With the absence of H. pylori, the team emphasized the importance of avoiding NSAIDs in the future and maintaining adherence to the prescribed PPI regimen. The patient was encouraged by these findings and expressed confidence in his ability to manage his condition moving forward.

Based on the successful stabilization of the patient's condition and the positive endoscopy findings, the healthcare team began planning for discharge. The patient was provided with detailed instructions on medication adherence, dietary modifications, and signs of potential complications to watch for at home. A follow-up appointment was scheduled with the gastroenterologist to monitor the ulcer's healing progress and to make any necessary adjustments to the treatment plan. The patient left the hospital with a clear understanding of the next steps in his care journey and a commitment to making the necessary lifestyle changes to prevent future exacerbations.

Upon discharge, the patient was instructed to monitor for any signs of gastrointestinal bleeding or complications. However, one week after returning home, he noticed a slight increase in abdominal discomfort and mild nausea. Concerned about these changes, he contacted his healthcare provider for advice. The provider recommended an evaluation to ensure that the healing process was continuing as expected and to rule out any new complications.

During the follow-up visit, the nurse conducted a thorough assessment. The patient's vital signs were stable: blood pressure was 120/80 mmHg, heart rate was 78 beats per minute, respiration rate was 16 breaths per minute, and temperature was 98.6°F. However, the patient reported some epigastric tenderness upon palpation and described his stools as darker than usual, which warranted further investigation. Concerned about the potential for occult bleeding, the healthcare team ordered a complete blood count (CBC) and a fecal occult blood test.

The lab results revealed a hemoglobin level of 12.5 g/dL, slightly lower than the previous value but still within a safe range, and the fecal occult blood test returned negative. These findings suggested that while there was some irritation, there was no active bleeding. The team concluded that the symptoms were likely due to ongoing inflammation, possibly exacerbated by dietary choices. The patient was advised to continue his prescribed Proton Pump Inhibitor (PPI) therapy, avoid irritants, and follow a bland diet to minimize gastric irritation. The nurse provided additional education on dietary modifications and comfort measures to alleviate symptoms. Reassured by the findings and guidance, the patient felt confident in managing his symptoms with the support of his healthcare team.

Several days after the follow-up visit, the patient experienced a noticeable improvement in his symptoms. The abdominal discomfort and mild nausea were significantly reduced, and he adhered to the dietary recommendations and medication regimen diligently. However, he began to notice intermittent episodes of mild dizziness, particularly when standing up quickly. Concerned about this new symptom, he contacted his healthcare provider once again for advice.

The nurse conducted another assessment over the phone, gathering relevant information to determine the cause of the dizziness. The patient reported that his fluid intake had been lower than usual due to his focus on dietary changes, and he had unintentionally been skipping some meals. The nurse advised him to ensure adequate hydration and maintain regular, small meals to stabilize his blood glucose levels and prevent orthostatic hypotension. The nurse also reviewed his current medication list to confirm that there were no interactions or side effects that could contribute to dizziness.

To monitor his condition further and ensure there were no underlying issues, the healthcare provider recommended a follow-up visit for a more comprehensive evaluation. The patient was reassured by the nurse's explanations and planned to implement the suggested changes. With a clearer understanding of the potential cause of his dizziness, he felt more empowered to manage this new development and looked forward to discussing his progress at the upcoming appointment.
