A 3-month-old neonate is admitted with suspected hydrocephalus. Upon assessment, which clinical manifestation should the nurse prioritize as indicative of increased intracranial pressure?

A. Bronchial smooth muscle relaxation and increased surfactant production is incorrect because asthma exacerbations are characterized by bronchoconstriction, not relaxation. Surfactant production is not the primary issue in asthma.

B. Acute upper airway infection leading to mucus obstruction in the sinuses is incorrect because while infections can trigger exacerbations, asthma itself is a lower airway disease involving the bronchi and bronchioles, not the sinuses.

C. Collapse of alveoli due to surfactant deficiency and impaired gas exchange is incorrect because this describes respiratory distress in premature infants (e.g., neonatal respiratory distress syndrome), not asthma.

D. Chronic airway inflammation, bronchoconstriction, and increased mucus production is correct because asthma is a chronic inflammatory disorder of the airways. During an exacerbation, inflammation causes airway edema, bronchial smooth muscle constriction narrows the airway, and excess mucus further obstructs airflow, leading to symptoms like wheezing, cough, and chest tightness.

A. Use the inhaler as needed during an asthma attack, but avoid overuse is correct. Albuterol is a short-acting beta-agonist (SABA) used as a rescue inhaler to relieve acute bronchospasm. It should be used during episodes of wheezing, coughing, or shortness of breath, but parents should be instructed not to overuse it, as excessive use can cause tachycardia, tremors, and decreased effectiveness. Monitoring frequency helps identify poorly controlled asthma that may require a review of the maintenance regimen.

B. Use the inhaler only when the child has difficulty breathing during physical activity is partially correct, but limiting it to activity-induced symptoms alone ignores other potential triggers, such as allergens or infections, which can also precipitate asthma attacks. Rescue inhalers are intended for all acute exacerbations, not just activity-induced ones.

C. Use the inhaler every 4 hours as a preventative measure is incorrect. Albuterol is not a maintenance or preventive medication; daily scheduled use is not recommended unless prescribed for specific short-term prophylaxis (e.g., before exercise). Long-term control requires inhaled corticosteroids or other controller medications, not a SABA.

D. Limit the use of the inhaler to prevent dependency on the medication is incorrect. Albuterol does not cause drug dependency, but overuse can indicate poor asthma control. The focus should be on appropriate use for symptom relief rather than fear of dependency.
