Which medication is NOT an appropriate choice for pain management?

• A. Mepederine
• B. Morphine
• C. Acetaminophen
• D. Ibuprofen

Answer: (A)

The main idea here is that not all pain-relief meds are equally suitable in every situation. Meperidine is not appropriate for routine pain management because its body breaks it down into a metabolite called normeperidine, which can build up especially in older adults or when kidney function is reduced. That metabolite can cause significant CNS side effects, including agitation, tremors, and seizures. Because of this risk, and because meperidine often provides less reliable, shorter-lasting analgesia compared with other opioids, it’s generally avoided in favor of safer, more effective options.

Other choices listed are commonly used for pain: morphine provides strong, reliable relief for moderate to severe pain; acetaminophen works well for mild to moderate pain and fever with a different mechanism and safety profile; ibuprofen offers anti-inflammatory pain relief but carries its own risks (like stomach, kidney, and cardiovascular concerns) that clinicians weigh against benefits.
