Which statement accurately reflects standard precautions as described?

• A. They apply only to infectious patients.
• B. They require no hand hygiene.
• C. They do not include safe injection practices.
• D. They include hand hygiene, PPE as needed, safe injection practices, and respiratory hygiene.

Answer: (D)

Standard precautions are the baseline approach to infection prevention used for every patient encounter. They require hand hygiene before and after patient contact, and after removing gloves, to remove transient microbes. PPE is used when there is a risk of exposure to blood, body fluids, or contaminated surfaces—gloves for contact with fluids, gowns when clothing could be contaminated, and masks or eye protection when splashes or droplets are possible. Safe injection practices mean using sterile, single‑use equipment for each patient and properly disposing of sharps, never reusing needles or syringes, and handling medications with aseptic technique. Respiratory hygiene and cough etiquette involve covering the mouth and nose when coughing or sneezing, using a mask if needed, and promoting spatial separation to reduce droplet spread. The statement that includes all these elements best reflects standard precautions. Statements that omit hand hygiene, exclude safe injection practices, or claim precautions are only for infectious patients do not align with the comprehensive, universal approach of standard precautions.
