enteral feeding - Nursing Case Study

Pathophysiology

• Primary mechanism: Enteral feeding delivers nutrients directly to the gastrointestinal (GI) tract, bypassing oral intake, which is crucial for patients unable to eat but have a functional GI tract. It ensures that the body receives essential nutrients for energy and cellular repair.

• Secondary mechanism: The presence of food in the GI tract stimulates intestinal motility and secretion, helping to maintain gut integrity and function. This is important for preventing intestinal atrophy and maintaining the gut's immune function.

• Key complication: Minor complications may include aspiration, where feeding contents accidentally enter the lungs, potentially leading to pneumonia. Careful patient positioning and monitoring can help mitigate this risk.

Section 1

Initial Assessment Findings:

Upon admission for enteral feeding initiation, the nursing assessment was conducted to establish a baseline for the patient's current status. The patient was alert and oriented, with a Glasgow Coma Scale score of 15. He reported mild discomfort when attempting to swallow solid foods, consistent with his history of dysphagia. Physical examination revealed no acute distress, and lung auscultation was clear bilaterally with no adventitious sounds, indicating no immediate signs of aspiration. The patient had a stable gait and required no assistance with mobility, although he expressed mild fatigue, likely related to his recent weight loss.

Nutritional assessment indicated that the patient had been consuming approximately 50% of his usual caloric intake due to swallowing difficulties. Laboratory tests showed a mild decrease in serum albumin levels at 3.2 g/dL, suggesting slight protein-energy malnutrition, but other electrolytes, including sodium, potassium, and blood glucose levels, were within normal limits. The patient's weight was recorded at 160 pounds, down from his usual 165 pounds, confirming the reported weight loss. A Speech-Language Pathologist was consulted, and a modified barium swallow study was scheduled to further evaluate the swallowing mechanism and rule out any structural abnormalities.

The nursing care plan focused on ensuring safe and effective enteral feeding. The patient's head of bed was elevated to 30-45 degrees during and after feedings to minimize aspiration risk, and continuous monitoring of respiratory status was emphasized. The interdisciplinary team, including dietitians and therapists, was involved to provide comprehensive care aimed at stabilizing the patient's nutritional status and addressing any swallowing difficulties. These steps set the stage for ongoing evaluation and potential adjustments to the feeding regimen based on the patient's response.

Response to Interventions:

Following the initiation of enteral feeding, the patient was closely monitored to evaluate his response to the nutritional intervention. Over the first few days, the nursing team observed a gradual improvement in the patient's energy levels, with reports of decreased fatigue and an increase in overall activity. Vital signs remained stable, with a blood pressure of 120/80 mmHg, heart rate at 72 beats per minute, and respiratory rate at 16 breaths per minute. The patient continued to be alert and oriented, and his weight stabilized at 161 pounds, suggesting a halt in weight loss.

The patient's serum albumin levels were reassessed and showed a slight improvement to 3.4 g/dL, indicating a positive response to the nutritional support. The modified barium swallow study conducted by the Speech-Language Pathologist revealed mild oropharyngeal dysphagia without any structural abnormalities, confirming that the enteral feeding route was appropriate and necessary to meet the patient's nutritional needs. No signs of aspiration were detected during the study, providing reassurance that the current feeding protocol was safe.

Throughout this period, the interdisciplinary team continued to collaborate effectively. Daily assessments ensured that the head of the bed was consistently elevated as recommended, and the patient's respiratory status remained clear with no signs of respiratory distress. The patient expressed satisfaction with the care provided and showed a willingness to continue with the current feeding regimen. The team planned to gradually advance the enteral feeding rate as tolerated, with the goal of fully meeting the patient's caloric and nutritional requirements while continuing to monitor for any potential complications.

New Complications:

Despite the positive initial response to the enteral feeding intervention, the patient began to experience minor gastrointestinal discomfort, characterized by mild abdominal bloating and occasional nausea. These symptoms were moderate and did not significantly impact the patient's overall well-being, but they warranted attention to ensure continued progress. The nursing team promptly reported these observations to the attending physician and the dietitian, who collaborated to adjust the feeding protocol. It was decided to slightly reduce the feeding rate and incorporate a prokinetic agent to help alleviate the gastrointestinal symptoms and promote more effective digestion and nutrient absorption.

During this adjustment period, the nursing team remained vigilant in monitoring the patient's condition. Vital signs continued to remain stable, with the blood pressure, heart rate, and respiratory rate all within normal limits. The patient's serum electrolytes were checked to rule out any imbalances that might contribute to the discomfort, and results showed normal ranges, including a sodium level of 140 mEq/L and potassium at 4.2 mEq/L. Additionally, the patient was encouraged to maintain a semi-upright position for at least 30 minutes post-feeding to aid in gastrointestinal comfort.

Over the following days, the patient reported a gradual reduction in bloating and nausea, and his overall comfort improved. The interdisciplinary team agreed to maintain the adjusted feeding regimen while continuing to monitor for any further complications. The patient's positive response to these interventions demonstrated the importance of individualized care and the need for ongoing assessment and collaboration among healthcare professionals. With the patient's gastrointestinal symptoms under control, the team planned to cautiously increase the enteral feeding rate once more, aiming to fully meet nutritional goals.

Section 4

Response to Interventions:

Following the adjustments to the enteral feeding protocol and the introduction of a prokinetic agent, the nursing team observed a steady improvement in the patient's gastrointestinal symptoms. The patient reported a significant decrease in bloating and nausea, expressing that he felt much more comfortable during and after feedings. Encouraged by these positive developments, the team noted that the patient was more engaged in daily activities and expressed a better overall sense of well-being.

To ensure the patient’s continued progress, the nursing staff conducted frequent assessments, meticulously documenting any changes in the patient's condition. Vital signs remained stable, with a blood pressure of 118/76 mmHg, a heart rate of 74 beats per minute, and a respiratory rate of 16 breaths per minute. The patient's weight was monitored daily to assess nutritional status, showing a slight increase of 0.5 kg over the past week, indicating improved nutritional absorption and a positive response to the feeding regimen.

With the patient's condition stabilizing, the interdisciplinary team agreed to cautiously increase the feeding rate incrementally while continuing to monitor the patient closely for any signs of discomfort or complications. The patient's improvement reinforced the importance of individualized care and timely adjustments in response to clinical findings. The team remained committed to reassessing the feeding plan regularly, ready to make further modifications as necessary to meet the patient's nutritional needs fully. As the patient approached his nutritional targets, the team anticipated a gradual transition to his next phase of recovery, with ongoing support from the nursing staff and other healthcare professionals.

Section 5

A week after the implementation of the updated enteral feeding protocol and the positive response to the prokinetic agent, the nursing staff observed a new set of assessment findings that required attention. During a routine check, the patient mentioned experiencing mild episodes of diarrhea, which had not been present before. Despite this new symptom, the patient continued to report feeling generally well, and his engagement in daily activities remained high. However, the nursing team recognized that the diarrhea could potentially affect the patient's fluid balance and nutritional absorption, necessitating prompt evaluation and management.

In response to this development, the team conducted a series of diagnostic tests to determine the cause of the diarrhea. Stool cultures were taken to rule out any infectious causes, and electrolytes were checked to assess for any imbalances. The results indicated a mild electrolyte disturbance, with a slight decrease in potassium levels. The interdisciplinary team, including the dietitian and the physician, reviewed the patient's current feeding formula and rate, considering the possibility of adjusting the formula to a more fiber-rich option to help manage the diarrhea while also ensuring that the patient's caloric and nutritional needs were met.

The nursing staff initiated a plan to address the new complication by closely monitoring the patient's fluid intake and output, as well as continuing to track his weight and vital signs. The patient was encouraged to report any changes in his symptoms promptly. The team remained attentive to the patient's overall condition, ready to make further adjustments to the feeding regimen as necessary. By maintaining a vigilant approach and collaborating effectively with the entire healthcare team, they aimed to resolve the diarrhea and support the patient in moving smoothly toward his recovery goals.
