A nurse is teaching a client who is to undergo placement of a nontunneled percutaneous central venous access device. Which of the following statements should the nurse include in the teaching?

Choice A reason: Asking parents to wait outside may increase the preschooler’s anxiety, as parental presence provides comfort. Unless clinically necessary, excluding parents is not ideal, so this action is inappropriate for preparing the child, making it incorrect.
Choice B reason: Teaching deep-breathing to a preschooler is challenging due to their developmental stage, and it may not effectively reduce anxiety for a dressing change. Simpler reassurance is more suitable, so this is less effective, making it incorrect.
Choice C reason: Explaining the procedure in simple terms helps the preschooler understand what to expect, reducing fear and promoting cooperation. This developmentally appropriate approach aligns with pediatric care principles, making it the correct action for preparation.
Choice D reason: Limiting teaching to 20 minutes is impractical for a preschooler, whose attention span is short. Brief, simple explanations are more effective, and prolonged sessions may overwhelm the child, so this is incorrect for preparing them.

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.
