action of this medication?
a) Reduce inflammation
b) Relax bronchial smooth muscle
c) Thin mucus secretions
d) Inhibit bacterial growth
b) Relax bronchial smooth muscle

5. A 5-year-old child with a seizure disorder is prescribed
phenobarbital. What lab test should be monitored?
a) Liver function tests
b) Renal function tests
c) Blood glucose

a) "Stop antibiotics when the child feels better."
b) "Always complete the full course of antibiotics."
c) "Save leftover antibiotics for future illness."
