The recommended daily allowance (RDA) for protein varies based on factors such as age, sex, and activity level. For instance, the RDA is generally 46 grams per day for women and 56 grams per day for men. However, certain patient populations, such as those experiencing malnutrition, undergoing dialysis, or recovering from surgery, may require higher amounts. Nurses should collaborate with dietitians to determine the appropriate protein intake for each patient.
