  2. Ejector tip (saliva ejector)
  3. Scalpel blade / used anesthetic carpule with blood
  4. Gloves without visible blood
Show answer and explanation

Correct answer: C. Scalpel blade / used anesthetic carpule with blood

  • A. Items that touched saliva without visible blood are NOT regulated waste — they are contaminated waste but not regulated biohazardous waste.
  • B. Saliva ejectors are NOT regulated waste unless visibly contaminated with blood — they go into regular waste.
  • C. SCALPELS and USED ANESTHETIC CARPULES WITH VISIBLE BLOOD are REGULATED WASTE. Regulated medical waste includes: liquid blood or blood products, items contaminated with blood that would release blood if compressed (saturated), pathological specimens, and contaminated sharps. Scalpel blades fall into contaminated sharps → regulated waste.
  • D. Gloves without visible blood contamination are NOT regulated waste — they go into regular waste.
