# 1. What are the possible indicators for PN? 2. What is central versus peripheral PN? Discuss the advantages and disadvantages of each. 3. What are the various macronutrients you can administer via PN and in what form? 4. What are some of the technical complications associated with PN? 5. What are some of the metabolic complications associated with PN and how would you address those? CALCULATIONS: 1. Calculate the number of calories and grams protein for the following TPN solution: D50W in 500cc 10% AA in 500cc 20% lipids in 350cc (given piggy back 3 times a week) Flow rate: 75cc/h x 24h 2. Calculate total calories and protein in 1 liter of the following solution: (assume that all of the macronutrients are provided in the same bag and the bag totals a volume of 1750ml) D70W in 750ml 15% AA in 500ml 20% lipid in 500ml 3. Calculate the total calories and grams of protein in a solution containing: (assume all of the macronutrients are in the same bag) D50W in 500ml 8.5 % AA in 300ml 10 % lipid in 200ml rate of 60 ml/h x 24h 4. Calculate total calories and grams of protein in the following solution: (assume that all of the macronutrients are provided in the same bag and the bag totals a volume of 1500ml) D70W in 500 ml 15% AA in 500 ml 20 % lipid in 500 ml 5. Recommend a TPN formula and rate for a patient requiring 2600-2800 kcal and 150 grams of protein. 6. Recommend a TPN formula and rate for a 70 kg male with ESRD requiring 35 kcal/kg and 0.6 g/kg protein. PN Indicators, Central versus Peripheral Feeding, and Macronutrients

The PN Indicators: Central versus Peripheral Feeding and Macronutrients

A form of nutrition called parenteral nutrition, or PN, is one that is delivered directly to a vein and bypasses your gastrointestinal tract. The primary function of parenteral nutrition is to supply adequate nutrition and water to patients who are unable to receive adequate nutrition from oral or enteral sources. Knowing the symptoms of PN is crucial. It also helps to distinguish between peripheral and central feeding and what macronutrients are available via PN. One indicator of PN is a patient’s inability to absorb oral or enteral nutrition due to conditions such as severe malabsorption or short bowel syndrome. One indicator of PN is a person’s decreased appetite or inability to digest food properly. A third indicator is when a patient’s nutritional needs exceed the capacity of oral or enteral feeds (Liu et al., 2020). The intravenous nutrition solution called central PN can be delivered through an intravenous catheter in one of the following veins: the jugular or subclavian. Long-term PN is best done using this method. Cont…
