A nurse accidentally spills blood on the countertop. Which is the correct sequence for decontamination?
Answer: Wipe visible blood away first, then apply an EPA-approved disinfectant
Visible organic material must first be removed mechanically because it inactivates disinfectants; then the surface is disinfected with an EPA-approved agent.
Which patient is the most appropriate candidate for protective (reverse) isolation?
Answer: A neutropenic patient receiving chemotherapy with ANC < 500
Protective isolation shields severely immunocompromised patients (like those with severe neutropenia) from environmental pathogens and staff/visitor organisms.
During a fire emergency (RACE protocol), what does the letter 'C' stand for?
Answer: Contain the fire by closing doors
In the RACE mnemonic — Rescue, Alarm, Contain, Extinguish/Evacuate — Contain means closing doors to slow fire and smoke spread.
The nurse is caring for a patient with herpes zoster (shingles) involving a rash covered by clothing. Which precautions are required?
Answer: Contact precautions in addition to standard precautions
Localized zoster with covered lesions requires contact precautions; disseminated or immunocompromised cases additionally require airborne precautions.
Which statement about hand hygiene timing is correct according to the WHO 'Five Moments'?
Answer: Hand hygiene must occur before and after patient contact, and after contact with the patient's environment
The WHO Five Moments include: before patient contact, before aseptic tasks, after body fluid exposure, after patient contact, and after touching the patient's environment.
A nurse removes an N95 respirator after caring for a patient with TB. Which is the correct removal technique?
Answer: Lift the bottom strap over the head first, then the top strap
The bottom strap is removed first to tilt the respirator away from the face, then the top strap is lifted off without touching the potentially contaminated front.
Which finding during a urinary catheter insertion would require the nurse to restart with a new sterile kit?
Answer: The catheter tip touches the inner thigh before insertion
If the catheter tip contacts any non-sterile surface (like the patient's skin) before insertion, the catheter is contaminated and a new sterile kit must be used.
