Which prescribed medication should a nurse administer to a client with an unprepared femur fracture reporting severe pain?

In the context of managing severe pain associated with an unprepared femur fracture, hydromorphone is the most appropriate medication to administer. Hydromorphone is a powerful opioid analgesic that is effective in mitigating severe pain due to its strong analgesic properties. It interacts with specific receptors in the brain and spinal cord to alter the perception of pain, making it particularly suitable for acute, intense discomfort like that associated with a femur fracture.

While ibuprofen and acetaminophen can be effective for moderate pain, they may not provide sufficient relief for the level of pain described in this scenario. Aspirin, similarly, is generally not utilized for severe pain management, particularly in acute situations. The choice of hydromorphone reflects both a clinical understanding of pain severity associated with fractures and the need for a stronger pain control mechanism in acute settings.
