Final answer:
Multimodal therapies include various medications and techniques customized to patient needs for effective postoperative pain management, rather than sole reliance on standardized orders or PCA devices.
Step-by-step explanation:
Multimodal therapies are indeed the cornerstone of postoperative pain management. These therapies often include a combination of opioids, such as morphine, oxycodone, and codeine, along with non-opioid medications and anesthetic techniques. They may also encompass nonpharmacologic methods to provide a comprehensive approach tailored to individual patient needs. As stated, using only PCA (Patient-Controlled Analgesia) devices or standing orders for medication administration may not be suitable for all patients. A patient's pain is complex, and what works for one might not work for another due to various factors. Instead, assessment tools combined with careful consideration of the patient's unique situation should guide the analgesic approach, rather than relying on a numerical scale to dictate opioid doses, acknowledging that this does not consider individual client circumstances.
