A nurse is reinforcing teaching with a guardian about receiving a PCA pump following a hysterectomy. Which of the following findings should the nurse include as a potential effect of the medication?

A. Increased senses: PCA pump use, typically involving opioids, does not heighten the senses. Instead, opioids often dull sensory perception and can cause sedation rather than making sensations sharper or more intense. B. Decreased sleep: Opioids used in PCA pumps often promote drowsiness and sleep rather than reducing it. Sleep disturbances are not a common direct effect of properly managed PCA analgesia unless pain remains uncontrolled. C. Difficulty swallowing: Difficulty swallowing is not a usual side effect associated with PCA use. If it occurs, it would likely suggest another issue, such as a neurological problem, rather than a typical reaction to PCA-administered opioids. D. Urinary frequency: Opioids can affect the bladder by either causing urinary retention or, less commonly, altering normal patterns. Clients receiving adequate hydration and pain management might experience urinary frequency, especially as mobility increases postoperatively.
