The nurse is caring for a client with superficial partial thickness burn injuries to the upper and lower extremities. The client is ordered IV morphine for pain. The nurse recognizes that narcotics are given IV during the initial management of pain based on which on which of the following rationales?

A. Damaged tissue and edema may interfere with drug absorption via other routes: Burn injuries impair tissue perfusion and cause significant edema, reducing the effectiveness of subcutaneous or intramuscular drug absorption. IV administration ensures reliable and immediate delivery of analgesics. B. The client can experience nausea and vomiting when given oral medications: While true, this is not the primary reason IV narcotics are preferred in the acute burn phase. The issue lies more with absorption and bioavailability than gastrointestinal tolerance. C. Pain resulting from a burn injury requires relief by the fastest route available: Although IV is the fastest route, the main rationale for choosing it is the unreliable absorption through other routes due to tissue injury, not just speed alone. D. Bleeding may occur at injection sites when the intramuscular route is used: This is less of a concern than the impaired absorption and delayed onset of action associated with IM administration in burn patients.
