Case Study Information: A 60 year old female has had surgery to remove an adrenal carcinoma (cancerous tumor of the adrenal gland). Her current body weight is 64 kg. She is 168 cm. Her calculated protein needs are 81 g/day. The patient has been NPO on IV fluids and electrolytes for 4 days. Vital signs are stable. GI motility is apparent. The physician recommends tube feeding, and recommends Nutren ®1.0 as the formula of choice. Below is the product information for this formula. Product Concentration Protein Carbohydrate Fat Osmolality % Free Water Nutren® 1.0 1.06 kcal/ml 16% kcal 51% kcal 33% kcal 330 mOsm/L 85% Calculate the patient’s energy needs for weight maintenance (total energy expenditure) using her current body weight. The Mifflin St. Jeor equation for women is: RMR= 10 x wt (kg) + 6.25 x ht (cm) – 5 x age (yrs) - 161 Assume a stress factor of 1.4 Calculate the patient’s daily fluid requirements using the kcal per mL method. Determine how many mL of formula will be needed to meet her caloric needs. How much free water will the formula provide this patient and how much free water will be needed from additional fluid sources? How much protein will be provided from this formula (g/day)? Given the calculated protein needs of the patient indicated above, is this formula a good choice? Please explain why or why not.
