Final answer:
Choosing option 1, which is to keep the tube feeding rate at 75 mL and adding a protein supplement, appears most suitable as it helps meet the required protein intake without exceeding calorie needs. Increasing the rate to 85 mL/hr may lead to exceeding the calorie limit.
Step-by-step explanation:
To determine whether to keep the tube feeding rate at 75 mL and add a protein supplement or to increase the rate to 85 mL/hr, we can calculate the additional nutritional needs that are not being met by the current tube feeding formula. With a requirement of 1800 - 2100 calories and 120-150 grams of protein, increasing the rate to 85 mL/hr could exceed the calorie requirements since the current rate already provides 1800 calories. Instead, option 1 appears more appropriate as it addresses the specific deficit in protein intake without overshooting the calorie requirement.
One packet of Beneprotein increases the protein by 6 grams without adding excessive calories, helping to meet the estimated needs of 120-150 grams of protein.
