CPN: Pediatric Respiratory Conditions

Preschoolers are highly egocentric and use magical thinking, often believing their thoughts or bad behaviors directly cause events. Clarifying that the illness is not a punishment relieves their misplaced guilt. Option A reinforces their misconception that their behavior caused the hospitalization. Option B misses the core issue of illness causation and focuses only on the sibling's feelings. Option D is too complex; while simple pictures are good, explaining pathophysiology exceeds the cognitive capacity of a five-year-old who needs emotional reassurance first.

The transition from loud wheezing to a silent chest alongside drowsiness indicates impending respiratory failure. The severe airway obstruction prevents adequate airflow to generate a wheeze. Preparing for advanced airway management is critical. Administering oral prednisone or incentive spirometry is inappropriate for a critically ill, drowsy child who cannot safely protect their airway. Transitioning to intermittent albuterol falsely assumes the absent wheezing represents clinical improvement rather than dangerous deterioration.

For a patient who relies heavily on strict home routines, hospitalization can be profoundly disorienting and distressing. Clustering nursing assessments to align with their established daily schedule provides predictability, which drastically reduces anxiety and the potential for sensory or emotional dysregulation. Option A is incorrect because random intervals of care eliminate predictability, keeping the patient in a constant state of heightened anticipation and stress. Option B is suboptimal because while respiratory monitoring is necessary for an asthma exacerbation, waking the patient frequently disrupts restorative sleep and exacerbates sensory irritability. Option C is inappropriate because introducing multiple new staff members increases social and sensory demands, whereas limiting the number of caregivers promotes trust and routine. Maintaining predictable routines is a cornerstone of autism-friendly hospital care.

A persistently elevated PEWS score despite targeted medical intervention indicates treatment failure and requires prompt provider reassessment. Notifying the attending provider ensures timely escalation and a potential change in the medical management plan. Repeating the albuterol without specific orders or evaluation is outside the nursing scope. Continuing monitoring or requesting a routine consultation fails to address the urgent need for a revised, escalated treatment plan.

Children with cystic fibrosis have a defective CFTR protein, leading to excessive sodium chloride loss in their sweat. During vigorous activities like a summer soccer camp, this loss accelerates, causing hyponatremia, fatigue, and muscle cramping. Providing salty snacks and electrolyte-rich sports drinks replenishes these critical electrolyte deficits. Option B is incorrect because restricting sodium would dangerously worsen the child's hyponatremia. Option C is incorrect because fatigue and cramping in this context are related to electrolyte imbalances, not a sudden need for additional digestive enzymes. Option D is incorrect because drinking plain water exclusively can dilute serum sodium further, exacerbating the cramping.
