Answer to Question 1

Provide 30-35 kcal/kg of IBW. Used his IBW for this calculation because he is obese and it is recommended to base calories on IBW for obese individuals. This caloric value is still enough to account for the hyper-metabolic state caused by pancreatitis (it is known that caloric needs increase by about 20).
EER: 2345-2736 kcal/d 30-35 kcal/kg IBW/per ASPEN guidelines
EPR: 94-117 g pro/d (1.2-1.5 g/kg IBW)

Answer to Question 2

Surgical resection: Removal of part of an organ or a structure in an attempt to remove the malignancy from the body.
Radiation therapy:
 Therapeutic radiation is the use of electromagnetic energy, which can destroy rapidly proliferating cells.
 It alters DNA enough to brake the cell cycle.
 It reduces tumor size and is often used in conjunction with other therapies.
Chemotherapy:
 Interrupts cell DNA, RNA, or protein synthesis of the cell cycle.
 Different types of drugs interrupt cell proliferation at different stages.
 It is common therapy to use a combination of drugs, which will enhance the effectiveness of treatment and minimize overall toxicity.
Immunotherapy:
 Also called biological therapy and biotherapy
 Medications that will stimulate your immune system and medications that contain components of the immune system such as interleukin or interferon
