A nurse is assisting with the care of a child who is in status asthmaticus. Which of the following medications should the nurse administer first?

A. Allowing a toddler to button up their own shirt can be frustrating for them as they may not have developed the fine motor skills required for this task, leading to potential distress.
B. Asking toddlers questions that require a "yes" or "no" answer can limit their language development as it does not encourage them to use language expressively.
C. While providing opportunities to share toys with others is important for social development, it is not the most critical aspect of care in this context.
D. Ensuring the toddler has at least one nap during the day is crucial as toddlers need ample sleep for proper development and to prevent overtiredness, which can affect their mood and behavior.

Rationale:

A. Skin turgor assessment is important in assessing dehydration, but the priority is addressing the tachycardia first.

B. Potassium level is important in managing electrolyte imbalance in gastroenteritis, but the priority is addressing the elevated heart rate first.

C. Capillary refill is an important assessment for circulation, but the priority is addressing the elevated heart rate first.

D. The elevated heart rate (tachycardia) indicates increased workload on the heart, likely due to dehydration or other complications of gastroenteritis. This requires immediate attention to stabilize the infant's condition.
