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 requires higher doses of a medication to achieve the same effect. In the case of morphine, tolerance can develop over time, leading to the need for increased doses for pain relief. This explanation aligns with the client's reported need to increase the morphine dose.
A: The client becoming addicted to the medication is not the appropriate explanation in this scenario. Addiction involves a psychological dependence on a substance, which is different from tolerance.
B: Episodes of confusion may be a side effect of morphine but do not explain the need for a dose increase.
C: If the client had not been taking the medication properly, it would likely result in decreased effectiveness rather than the need for a higher dose.
In summary, the correct answer is D because it directly addresses the client's need for a higher morphine dose due to developing tolerance, while the other choices do not appropriately explain the situation.
