Morphine can be given by all the following routes except:
**Core Concept**
Morphine is a potent opioid analgesic used to manage moderate to severe pain. Its administration via various routes is crucial in clinical practice, taking into account factors like onset of action, duration of effect, and patient comfort.
**Why the Correct Answer is Right**
Morphine can be administered through several routes, including intravenous (IV), intramuscular (IM), subcutaneous (SC), epidural, spinal, and oral routes. The IV route provides rapid onset of action due to direct absorption into the systemic circulation. The IM route is commonly used for emergency situations where IV access is not available, as it allows for relatively rapid absorption. SC administration is less common but can be used in specific circumstances. Epidural and spinal administration are typically reserved for regional anesthesia and pain management in the perioperative period. Oral morphine is a convenient option for chronic pain management, as it avoids the need for injections.
