1
Describe:

Standard (universal) Precautions

Standard (universal) precautions:

  • assumes that blood or body fluids by ANY client can be infectious
  • PPE: gloves, goggles, gown, and mask
    • use your judgment on what to wear
  • use a sharps container
  • hand hygiene
  • keep 3 feet away and cover mouth when coughing or sneezing
  • offer mask to clients with respiratory symptoms

All clients are on standards precautions.

2
Describe:

Transmission-based Precautions

Transmission-based precautions are beyond standard precautions because the disease is highly contagious:

  • Airborne precautions
  • Droplet precautions
  • Contact precautions

3
Describe:

Airborne Precautions

Airborne precautions are taken for highly contagious diseases that are transmitted by airborne droplet nuclei that go over long distances and remain suspended in the air for long periods.

  • PPE: N95 particulate respirator mask
    • possible gown, gloves, goggles
  • negative pressure isolation room with at least 6 air exchanges per hour
  • client wears a surgical mask if leaving room

This includes dried droplets and dust particles containing infectious material.

4

Which diseases use Airborne Precautions?

Use the mnemonic MTV to remember the most common.

Diseases that use Airborne precautions:

  • measles (Rubeola)
  • tuberculosis
  • varicella-zoster / chickenpox
  • shingles/herpes zoster

These diseases are also contact precautions.Use the mnemonic MTV: measles, TB, varicella to remember the most common airborne diseases.

 

5
Describe:

Droplet Precautions

Droplet precautions are taken for highly contagious diseases that are transmitted by large-particle droplets that travel up to 3 feet or less through the air. 

  • PPE: surgical mask if within 3 feet of client
    • possible gown, gloves, and goggles

Droplets come from sneezing, coughing and talking.

  • adenovirus

Use the mnemonic SPIDERMAN to remember.

7
Describe:

Contact Precautions

Contact precautions are taken for highly contagious diseases that are transmitted by direct or indirect contact.

  • always wear gown and gloves
  • if splashing is expected, wear goggles and mask

Common sources of indirect contact are the stethoscope and keyboard.

8

Which most common diseases use Contact Precautions?

Most common diseases that use Contact Precautions:

  • multidrug-resistant organisms
    • VRE, CRE, MRSA (will have the word "resistant" in the name)
  • diarrhea/enteric (in the gut)
    • C. diff, E. coli, Shigella, hepatitis A & E, rotavirus
    • any type of diarrhea or diaper changes for children and adults
    • enteroviral
  • skin and wound infections
    • cutaneous diphtheria, herpes simplex virus, impetigo, abscesses, cellulitis, decubitus ulcers, pediculosis, smallpox, staphylococcal furunculosis, scabies, zoster

Most students will not memorize this list, but be able to recognize the disease as contact precautions.​

9

Which additional diseases use Contact Precautions?

Additional diseases that use Contact Precautions:

  • eye infections
    • viral or hemorrhagic conjunctivitis
  • viral blood infections
    • Ebola, Lassa, Marburg
  • respiratory syncytial virus, parainfluenza virus

10
Describe:

Enteric precautions

Enteric precautions are taken to prevent infections that are transmitted by fecal material. Enteric precautions include:

  • Contact Precautions
  • washing hands with soap and water (no alcohol)
  • PPE: gloves and gown (googles and mask if splashing is expected)

 

11

Which diseases use Enteric Precautions?

Diseases that use Enteric Precautions:

  • Infectious diarrhea
    • Clostridium difficile
    • gastroenteritis
    • rotavirus
    • norovirus

12

What type of room does a client on transmission-based precautions get?

Transmission-based precautions

  • preferably put all clients with an infectious disease in their own private room to prevent cross-infection.

Clients with the same exact infectious disease can be roomed together. It is sometimes referred to as "room like with like".

13

Where do needles go after being used?

Place used needles in a sharps container/puncture-resistant container designated for needles.

14

What can the nurse use to prevent needle sticks?

Needleless devices

15

What type of bag does hazardous waste and blood go into?

A biohazardous waste bag

16
Define:

A nosocomial infection is an infection acquired while in the hospital.

17

What are the most common nosocomial infections?

Most common nosocomial infections:

  1. C diff. - clostridium difficile
  2. VRE - vancomycin-resistant enterococci
  3. MRSA - methicillin-resistant staph aureus
  4. CRE - carbapenem-resistant Enterobacteriaceae

18

When is the N95 / particulate respirator removed?

Take off the N95 respirator mask outside of the client's room after their door has been closed.

19

What does the client wear when leaving the room when they are on airborne precautions?

The client wears a surgical mask.
