Answer to Question 1

B
The recommended loading dose of IV aminophylline is 5 to 7 mg/kg, which is a dosage between 100 and 140 mg. The 500-mg prescription is between four and five times the recommended dose. It is possible that this is the dosage that is needed; however, because it is very far out of the rec-ommended range, the dosage should be rechecked with the prescriber (and a pharmacist). If this dosage is to be administered, the child should be in an intensive care unit.

Answer to Question 2

A
The therapeutic range for theophylline is very narrow (10 to 20 mcg/mL). If the drug blood levels are lower than 10 mcg/mL, the patient's symptoms will not be controlled. If the drug blood levels are higher than 20 mcg/mL, the patient may have serious adverse reactions. Blood levels of this drug need to be monitored closely to ensure safe and effective drug delivery.
