A nurse is caring for a client who has lung cancer and has a sealed radiation implant. Which of the following actions should the nurse take? (Select all that apply)

Choice A reason: Decreasing fluid intake to firm stools is incorrect, as adequate hydration (2-3 L/day) is essential to prevent constipation, especially with opioids like oxycodone, which slow intestinal motility. Low fluid intake hardens stools, exacerbating constipation risk by reducing water content in the colon, indicating a misunderstanding of prevention strategies.
Choice B reason: Increasing dietary fiber intake (25-35 g/day) adds bulk to stools, stimulating peristalsis and counteracting opioid-induced slowed motility. Soluble and insoluble fiber, found in fruits, vegetables, and whole grains, promotes regular bowel movements. This statement reflects correct understanding of dietary measures to prevent constipation during opioid therapy.
Choice C reason: Taking a laxative only when constipated is reactive, not preventive. Opioids like oxycodone commonly cause constipation by reducing peristalsis via mu-opioid receptors in the gut. Prophylactic use of stool softeners or laxatives is recommended to maintain regular bowel movements, making this statement incorrect as it lacks a preventive approach.
Choice D reason: Exercising less to conserve energy worsens constipation, as physical activity stimulates intestinal motility, countering opioid-induced slowing. Regular movement, like walking, promotes bowel function by enhancing peristalsis and blood flow to the gut. This statement indicates a misunderstanding, as reduced activity increases constipation risk.

Choice A reason: Marking drainage output every 48 hours is too infrequent to accurately assess drainage in a closed wound drainage system. Frequent monitoring (e.g., every shift) is needed to track output, detect complications like excessive bleeding, and ensure system functionality, making this intervention inadequate for assessment.
Choice B reason: Stripping the chest tube vigorously is not recommended, as it can increase intrathoracic pressure, risking tissue damage or bleeding. It does not assess drainage amount but manipulates the tube, potentially causing harm. Assessment requires observing output in the collection chamber, making this action incorrect.
Choice C reason: Maintaining the collection chamber below the client’s chest ensures proper drainage by gravity in a closed wound drainage system, like a chest tube. This position prevents backflow and allows accurate measurement of drainage output in the chamber, essential for assessing fluid loss and detecting complications like hemothorax.
Choice D reason: Adding water to the water seal chamber maintains system function but does not directly assess drainage amount. The water seal prevents air re-entry, not measures output. Assessment involves observing and recording drainage in the collection chamber, making this action irrelevant to the question’s focus.
