Answer to Question 1

B
Therapeutic blood level for theophylline is 10 to 20 mg/dL.

Answer to Question 2

D
The most common cause of death of patients with GBS is respiratory arrest; thus, the highest nursing priority for a patient with Guillain-Barr  syndrome is directed toward providing ventilatory support and maintaining surveillance for complications. Facilitating nutritional support, providing comfort and emotional support, and educating the patient and family are important but rank lower than issues with the respiratory system.
