The nurse recognizes which of the following clients as being at greatest risk for a negative nitro-gen balance?
1. A 10-year-old with an infected laceration on the left thumb
2. A 75-year-old who fell and experienced a mild concussion
3. A 40-year-old who has partial-thickness burns over 15% of his body
4. A 19-year-old who has lost 70 pounds in 7 months as a result of dieting
ANS: 3
Negative nitrogen balance occurs when the body loses more nitrogen than the body gains, for example, with infection, sepsis, burns, fever, starvation, head injury, and trauma. Although all these clients may be experiencing an increased nitrogen need for body repair, the burn client has the greatest need and so is at greatest risk for a negative nitrogen balance.
