An older adult has received 3,000 mg of acetaminophen in 24 hours from combination products, and a 650 mg dose is due. What should the nurse recognize?

  1. The dose is safe because the adult limit is 5,000 mg
  2. The dose is safe if given with food
  3. The dose would exceed the 3,200 mg limit for older adults and risk liver damage

Show answer
