Sterile technique is essential in which scenarios?

• A. Injections
• B. Wound care
• C. Minor surgical procedures
• D. All of the above

Answer: (D)

Sterile technique is essential whenever there’s a real risk of microbes entering normally sterile tissues or spaces. Injections pierce the skin and can introduce bacteria into muscle or the bloodstream, so using sterile needles, syringes, proper hand hygiene, and site preparation minimizes infection risk. Wound care involves open or damaged skin, where microbes can readily invade; keeping the wound area clean and using sterile dressings helps prevent infection and promote healing. Even minor surgical procedures create a sterile field and involve incisions into tissue, so strict sterility reduces the chance of surgical-site infection and sepsis. Because these scenarios all carry infection risk if sterility isn’t maintained, all of the above is correct.
