Morphine is commonly used to treat which level of pain?

• A. Mild pain
• B. Moderate pain
• C. Severe pain
• D. Pain in mild strenuous activity

Answer: (C)

Morphine is a strong opioid analgesic used for severe pain. Pain intensity is often thought of on a scale where mild is low-level discomfort, moderate is noticeable but manageable, and severe is intense and typically requires potent relief. Because morphine is potent and carries risks such as respiratory depression, sedation, constipation, and potential dependence, it’s reserved for severe pain where safer, weaker analgesics aren’t enough. It provides substantial relief for things like cancer-related pain, postoperative pain, or other severe acute pain. For mild pain, non-opioids like acetaminophen or NSAIDs, or nonpharmacologic approaches, are usually sufficient and safer. The idea of using morphine for pain only during mild strenuous activity isn’t appropriate, since the risks would outweigh the benefit for that level of discomfort.
