Question

A client receiving morphine for long-term pain management develops tolerance. Tolerance is defined as:

1. an increased response to a medication.
2. a diminished response to a drug so that more is required to achieve the same effect.
3. an allergic reaction to a medication.
4. an ability to take the same drug for extended periods of time.

Answer 1

Tolerance is a diminished response to a drug, requiring higher doses to achieve the same effect. In the case of morphine for long-term pain management, tolerance would mean needing higher doses to experience the same level of pain relief.

Step-by-step explanation:

Tolerance is defined as a diminished response to a drug, so that more of the drug is required to achieve the same effect. In the case of a client receiving morphine for long-term pain management, tolerance would mean that over time, the client would need higher doses of morphine to experience the same level of pain relief. This is because the body adapts to the presence of the drug and becomes less responsive to its effects.
