Zorluk: ZorStandard and Transmission-Based Precautions

A glass laboratory tube shatters in a high-traffic clinical hallway, resulting in a significant blood spill. Arrange the following infection control actions in the correct chronological sequence. All options must be used.

  1. 1Restrict access to the immediate perimeter to prevent accidental exposure or tracking.
  2. 2Apply required personal protective equipment including gloves, gown, and facial protection.
  3. 3Cover the spill with absorbent material to soak up the visible blood.
  4. 4Collect the saturated material and glass shards using mechanical tongs.
  5. 5Apply a hospital-grade disinfectant to the surface and allow for the required wet time.

Cevap

The correct sequence is to first restrict access to the area, then apply personal protective equipment, cover the spill with absorbent material, remove the material and glass with mechanical tongs, and finally apply a hospital-grade disinfectant.
Safe management of a biohazardous spill requires a systematic approach. The nurse must prioritize immediate environmental safety by restricting access. Next, the nurse protects themselves by donning PPE. The actual cleaning process requires a two-step method: first, removing the organic bioburden by absorbing and picking it up (using mechanical means to avoid sharps injury), and second, chemically disinfecting the pre-cleaned surface.

Adım Adım Çözüm

1
Restrict access to the immediate perimeter.
Secures the environment from foot traffic.
Prevents cross-contamination and accidental sharps exposure while the nurse gathers necessary clean-up supplies.
2
Apply required personal protective equipment.
Protects the healthcare worker from exposure.
Standard precautions dictate that appropriate barrier protection must be worn before handling blood, body fluids, or contaminated sharps.
3
Cover the spill with absorbent material.
Contains the fluid and prevents splashing.
Organic material must be absorbed prior to disinfection because heavy bioburdens (like pooled blood) inhibit the efficacy of chemical cleaning agents.
4
Collect the saturated material and glass shards using mechanical tongs.
Removes the physical and biological hazard safely.
OSHA and standard guidelines mandate that broken glassware that may be contaminated must not be picked up directly with the hands.
5
Apply a hospital-grade disinfectant to the surface.
Destroys remaining microscopic pathogens.
Applying the disinfectant to a pre-cleaned surface and allowing the required contact time ensures complete decontamination.
