Going to bed hungry or overly full does not interfere with sleep.

It helps the patient reach REM state of sleep faster.

Choice A rationale:
The primary care provider (PCP) is responsible for prescribing the PCA but does not typically program the PCA pump. The PCP may set the initial parameters for the PCA, such as the dose and lockout interval, but the actual programming and operation of the PCA pump is typically carried out by the nursing staff.
Choice B rationale:
Pharmaceutical companies manufacture and provide medications, including the medications used in PCA, but they do not program PCA pumps. Programming and administration of the PCA are nursing responsibilities.
Choice D rationale:
Licensed Practical Nurses (LPN) or Licensed Vocational Nurses (LVN) can assist in the administration and monitoring of PCA, but they do not typically program the PCA pump. Registered nurses are usually responsible for the programming and operation of PCA pumps.

Choice A rationale:
Using a pain scale from 0 to 10 is a crucial principle in managing a client's postoperative pain. It allows for a standardized assessment of pain severity and helps healthcare providers determine the effectiveness of pain management interventions.
Choice B rationale:
Considering the client's individual expression of pain is essential in providing personalized care. People experience and express pain differently, so tailoring the approach to each client's unique needs is vital for effective pain management.
Choice C rationale:
Expecting the client to express pain both verbally and nonverbally is another important principle in pain management. Some clients may not be able to communicate verbally, so nurses should be attentive to nonverbal cues such as grimacing, restlessness, or changes in vital signs to assess pain.
Choice D rationale:
Administering opioids with caution is a general principle in pain management, but the statement that they will eventually lead to addiction is an oversimplification. While there is a risk of opioid addiction, it is not an absolute certainty, and the benefits of pain relief often outweigh the risks. Therefore, this statement is not entirely accurate.
Choice E rationale:
Administering analgesics for fast-acting pain relief is a valid principle, especially in the postoperative period when the client may be experiencing acute pain. Fast-acting analgesics help alleviate immediate discomfort.
