If a child's theophylline level is 25 mcg/dL, what action should the nurse take?

The appropriate action when a child's theophylline level is 25 mcg/dL is to notify the healthcare provider. Theophylline is a medication used primarily for respiratory conditions such as asthma or chronic obstructive pulmonary disease, and it has a narrow therapeutic index. This means that the difference between an effective dose and a toxic dose is small.

A theophylline level of 25 mcg/dL is considered elevated, as the therapeutic range typically lies between 10 and 20 mcg/dL. Levels above this range increase the risk of toxicity and related adverse effects, which can include symptoms such as nausea, vomiting, increased heart rate, and seizures. Due to the potential risks associated with elevated theophylline levels, prompt notification to the healthcare provider is essential for further assessment and possible adjustment of the dose or additional interventions.

While sharing results during the end of shift report, repeating the laboratory test, or administering the medication as ordered may seem appropriate at different times, they do not address the immediate concern of a potentially harmful theophylline level. Thus, notifying the healthcare provider is the correct and necessary action to ensure the child's safety and well-being.
