A nurse is caring for a client who is 6 hr postoperative following an open reduction internal fixation to the left hip. The nurse should use which of the following routes to administer pain medication?

Postoperative pain management requires rapid onset of action to maintain the client within a therapeutic comfort window. During the immediate post-anesthesia period (the first 24 hours), the gastrointestinal tract may have decreased motility, making systemic absorption via the bloodstream the most reliable method. Effective analgesia is crucial for early mobilization and preventing complications like venous thromboembolism. Rationale: A. The intravenous route is the priority for a client who is only 6 hours postoperative because it provides immediate bioavailability and rapid peak effect. Following a major orthopedic surgery like a hip fixation, pain levels are typically high and require the fast-acting relief that IV opioids or non-opioids provide. This route allows for precise titration of the medication based on the client’s immediate pain response. B. The oral route is generally avoided in the very early postoperative period due to the risk of postoperative ileus and nausea related to anesthesia. Oral medications have a slower onset of action, typically taking 30 to 60 minutes to reach peak effect, which is insufficient for acute, severe surgical pain. This route is more appropriate once the client is stable and bowel sounds have returned. C. Sublingual administration is useful for certain medications but is not the standard of care for acute postoperative pain following major surgery. Most potent surgical analgesics are not formulated for sublingual use. The nurse requires a route that can deliver a wide range of analgesic agents reliably, making the intravenous route superior for the immediate recovery phase of a hip surgery. D. The intramuscular route is generally discouraged for postoperative pain because it is painful, results in inconsistent absorption, and has a slower onset than the intravenous route. Repeated IM injections can cause tissue damage and hematomas, especially in surgical clients who may be on anticoagulants. Modern nursing practice favors IV access for acute pain to ensure consistent and rapid relief.
