A pediatric patient has a physician's order that reads, "Give hydrocodone/acetaminophen (Lortab) elixir 10 mL PO for pain every 6 hours." The nurse identifies that a 15 mL container has 7.5 mg of hydrocodone and 325 mg of acetaminophen. How many mg of hydrocodone would the nurse be administering to this patient? (If <1 round to hundredth, if >1 round to tenth. Use numerical answer only.)
