Final answer:
The nurse should inform the client that the medications used for anesthesia can disturb sleep cycles for several weeks following surgery.
Step-by-step explanation:
The nurse should inform the client that the medications used for anesthesia can disturb sleep cycles for several weeks following surgery. After surgery, it takes time for the body to recover and for the effects of anesthesia to wear off completely. Sleep disturbances are a common side effect of anesthesia and can last for weeks or even months. It is important for the nurse to reassure the client that this is a normal part of the recovery process and that the sleep disturbances will likely improve over time.
