In the past month pt has been experiencing nausea, vomiting, and 10# of unintentional weight loss. His TPN formula and feeding rate has remained the same, and the formula has been compounded to meet his caloric and RDI needs.

Nutrition Diagnosis/ PES Statement: __________________________________________ ________________________________________________________________________ 2. Mrs P is a 50 y/o patient with severe ulcerative colitis. Her most recent attack required her to be on complete bowel rest. TPN was therefore administered. Day 2 after TPN was administered, Mrs P experienced hypertriglyceridemia.

Skins on her limbs are starting to flake as well. Nutrition Diagnosis/ PES Statement: __________________________________________ ________________________________________________________________________

TPN PES Statements In-Class Assignment

PES Statement 1 for 65 y/o Male on TPN after Bowel Resection
Nutrition Diagnosis/ PES Statement:
Inadequate oral intake related to gastrointestinal intolerance (nausea and vomiting) as evidenced by a 10-pound unintentional weight loss over the past month during TPN therapy.
Rationale:
In this case, the patient exhibits noticeable symptoms of gastrointestinal distress, specifically nausea and vomiting, which can affect the efficacy of Total Parenteral Nutrition (TPN) therapy. The weight loss indicates that the caloric needs are not being effectively met, despite having a TPN formula that is supposedly adequate for the patient’s requirements. The written PES statement reflects three components: the problem (inadequate oral intake), the etiology (gastrointestinal intolerance), and the signs and symptoms (unintentional weight loss, nausea, and vomiting). Impacted by these factors, the patient's nutritional status is compromised, underscoring the need for careful assessment and potential modification of the TPN formula or therapy approach (McCarthy et al., 2022).

PES Statement 2 for Mrs. P with Severe Ulcerative Colitis on TPN
Nutrition Diagnosis/ PES Statement:
Excessive nutrient intake related to the administration of TPN as evidenced by hypertriglyceridemia and flaking skin.
Rationale:
Mrs. P’s condition reflects a complication frequently associated with TPN: the development of hypertriglyceridemia. This makes it clear that her TPN formula might be delivering excess amounts of lipids, thus contributing to abnormal triglyceride levels indicative of lipid overload. Additionally, skin manifestations such as flaking may suggest deficiencies or excesses in essential fatty acids or other micronutrients, necessitating reassessment of her nutritional formula including its lipid composition and caloric distribution (DeLegge et al., 2017). The PES statement captures the relationship between the excessive nutrient intake (overly high lipid content in TPN) and its adverse effects (hypertriglyceridemia and skin changes).

Conclusion

Both PES statements provided for the case scenarios address the importance of thorough nutritional assessments in patients on TPN. Utilizing a structured approach allows healthcare providers to identify nutritional problems, their underlying causes, and the clinical manifestations present in each case. Consequently, both statements support critical thinking in medical nutrition therapy and reinforce the need for possible dietary regimen adjustments to enhance patient outcomes. Such considerations are crucial for preventing complications associated with TPN therapy and ensuring the patients receive appropriate nutritional care throughout their treatment.
