Quick answerContinue evidence-based emergency asthma therapy and monitoring while preparing IV magnesium as prescribed; do not delay or depress respirations.
Why this is correctBronchodilators address airway smooth-muscle constriction, ipratropium adds bronchodilation in severe exacerbations, corticosteroid treats inflammation, and oxygen treats hypoxemia. Persistent severe obstruction may warrant IV magnesium while advanced support is prepared.
Easy analogy or mental pictureThink of opening a narrowed tunnel while supporting traffic through it: bronchodilators widen the path, corticosteroid reduces swelling over time, and oxygen supports the child during the repair.
Memory hookOpen, oxygenate, treat inflammation, escalate.
NCLEX decision ruleWhen severe asthma does not respond promptly, continue first-line therapy and escalate respiratory support; never substitute calming delay or a respiratory depressant.
Why the other choices are wrongCoaching alone cannot reverse severe obstruction, and waiting wastes time. Opioids can worsen hypoventilation in a child already showing fatigue.
