Protein can be lost through wound drainage but the main cause for deficiency is
inadequate intake
Protein is `___% nitrogen; it is desirable to maintain an adequate nitrogen balance for proper wound healing.
16%
Is recommended to maintain a positive nitrogen balance which is noted by intake of what amount of protein? _____kg/BW daily

We receive energy from carbohydrates primarily in the form of-______?
GLUCOSE, which provides energy needed for tissue reapir, regeneration, and phagocytosis
If sufficient energy is NOT attained from the patients diet, the body will convert fat and protein to energy. This is known as
the protein sparing effect , this process solves energy problems, but if protein sources are not replenished, the patient will develop a protein defecit, which slows/halts wound healing.

the kidenys
Hypophosphatermia is caused by
- Vitamin D deficiency
- Prolonged respiratory alkalosis
- GI malabasorption
- excessive use of antacids
Which mineral assists in normal immune system function and supplemation is not recommended due to adverse effects that decreases the ability to fight infection.
