Question 1 of 5
A hospice nurse is caring for a client who has terminal cancer and takes PO morphine for pain relief. The client reports that he had to increase the dose of morphine this week to obtain pain relief. Which of the following scenarios should the nurse document as the explanation for this situation?
Correct Answer: D
Rationale: The correct answer is D: The client developed tolerance to the medication.
Tolerance occurs when a person needs higher doses of a medication to achieve the same effect over time. In this scenario, the client had to increase the dose of morphine to achieve pain relief, indicating tolerance. Option A (addiction) implies a psychological dependence, not the case here. Option B (confusion) is not directly related to morphine tolerance. Option C (not taking medication properly) would lead to inadequate pain relief, not the need for increased dosage. Thus, the most logical explanation is tolerance due to the body adapting to the medication.
