A nurse is teaching about preventing constipation to a client who has a new prescription for oxycodone. Which of the following statements by the client indicates an understanding of 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: Performing postural drainage immediately after meals risks aspiration and discomfort due to gastric contents shifting during positioning. It should be done 1-2 hours after meals to ensure safety and efficacy in clearing mucus from the lungs, making this timing inappropriate for cystic fibrosis management.
Choice B reason: Performing postural drainage twice daily is recommended for cystic fibrosis to mobilize thick mucus from the lungs, improving airway clearance and reducing infection risk. This frequency balances effectiveness with patient tolerance, aligning with evidence-based guidelines for managing chronic respiratory conditions, making it the correct action.
Choice C reason: Using a percussion vest is an alternative to manual postural drainage but is not specified as the only method. Manual techniques are effective and standard unless a vest is prescribed. This choice assumes equipment availability, which may not apply, making it less universally appropriate than scheduled manual drainage.
Choice D reason: Positioning the child flat during postural drainage is incorrect, as specific angled positions (e.g., head-down) are needed to target lung segments and promote mucus drainage by gravity. Flat positioning reduces effectiveness and may not clear airways adequately, making this an inappropriate technique for cystic fibrosis.
