Final answer:
The client's medication regimen may necessitate the intervention of stool softeners and increased fluid intake to alleviate constipation caused by opioid analgesics.
Step-by-step explanation:
The client's frequent scheduled and breakthrough doses of opioid analgesics may necessitate the intervention of stool softeners and increased fluid intake. Opioid analgesics have a common side effect of constipation, and the client's medication regimen is likely causing this issue. Stool softeners can help alleviate constipation and make it easier for the client to have bowel movements, while increased fluid intake can help soften the stools and prevent constipation.
