Final answer:
Encourage the nurse to independently observe the same situation with a peer, validate the data, and discuss the situation afterward.
Step-by-step explanation:
A corrective action for the novice nurse's erroneous interpretation of data would be to encourage the nurse to independently observe the same situation with a peer, validate the data, and discuss the situation afterward. This approach allows the nurse to gain a different perspective and verify the accuracy of the data collected. Additionally, discussing the situation with a peer can provide valuable insights and help the nurse arrive at the correct interpretation of the data.
