Week 10 elimination issues Flashcards
1
Q
What are the 6 things nurses monitor for with someone with altered kidney function and why?
A
- Fluid balance - hemodynamic status influences kidney function & specific gravity/osmolality
- Serum BUN & creatinine - indicator of kidney function
- Serum K - kidneys process most K+ so too much = kidneys not doing well
- Acid base balance - increase in uric acid
- Pain - can lead to hypotension
- Signs of infection - kidney damage and possibly lead to sepsis / septic shock
2
Q
Why is K+ high in someone with kidney issues?
A
90% of K+ is secreted through the kidneys. If Kidneys can’t manage the K then serum increases
