Which component of the clients nephron acts as a receptor site for the ADH to regulate water balance?
Collecting ducts - they regulate water balance and act as a receptor site for ADh
The nurse assesses a client's IV site. Which clinical finding leads the nurse to conclude that the IV has infiltrated, rather than caused inflammation?
Coolness When an IV infiltrates, the IV solution entering the interstitial space is at room temperature, whereas body temperature is approximately 98.6 F; therefore the client's skin will feel cool to the touch at the site of an IV infiltration
