A. The client has become addicted to the medication. B. The client is experiencing episodes of confusion. C. The client developed a tolerance to the medication. D. The client not been taking the medication properly.

Correct Answer is C

Explanation

A. The client has become addicted to the medication. – Addiction involves compulsive drug-seeking behavior and use despite harm. In a hospice setting, tolerance and dependence are expected and should not be confused with addiction.
B. The client is experiencing episodes of confusion. – While morphine may cause confusion, especially in elderly or very ill clients, this does not explain the need for a higher dose for pain relief.
C. The client developed a tolerance to the medication. – Tolerance occurs when the body becomes accustomed to a drug, requiring higher doses to achieve the same effect. This is common with long-term opioid use for chronic or terminal pain.
D. The client has not been taking the medication properly. – There is no indication of noncompliance. The need for a higher dose is more accurately attributed to tolerance, especially in terminal illness.
