A parent brings their child, who has a history of asthma, to the emergency room. The child is wheezing and speaking one word between each breath. The child is anxious, tachycardic, and has labored respirations. Which assessment is most important for the nurse to obtain?

A. Frequency that the child uses a rescue inhaler during the week: While it is important to know how often the child uses a rescue inhaler, it does not provide immediate, critical information to assess the severity of the current asthma attack. B. Type of inhaler the child typically uses on a regular basis: While knowing the type of inhaler the child uses regularly can provide insight into their asthma management, it is not the most critical information at this moment, the current treatment is he most urgent. C. Type of allergen exposure or trigger for the current episode: Understanding the trigger for the current asthma episode is helpful for long-term management but is not as urgent in the immediate assessment of the child’s condition during an acute exacerbation. D. Last dose and type of rescue inhaler used by the child: This information helps assess whether the child has received appropriate treatment and whether additional or different interventions are needed immediately to address the asthma exacerbation, helps guide further treatment decisions.
