The teacher will distribute the 2.02 Chain of Infection Activity Handout, or six strips of paper as illustrated in the handout. 2. Instruct the students to listen and follow directions as information is given about the links in the chain of infection from the PowerPoint Presentation. 3. Elaborate on the information one link at the time, beginning with “causative agent”. 4. Lead the students to write keys point about causative agent on the appropriate strip of paper. 5. Students will form a loop with the first strip (causative agent) and staple it to form a circle. 6. Teacher provides information about the second link (reservoir), students write key points on the link labeled “reservoir”. 7. Students add the second link (reservoir), to the first link (causative agent), to begin forming a paper chain. 8. Repeat until all links are addressed. 9. Links should be addressed in this order: causative agent, reservoir, portal of exit, mode of transmission, portal on entry, and susceptible host. 10. After teacher has provided information about each link and students have completed the chain, ends linked together, review the total chain of infection. 11. Teacher will explain that to prevent the spread of infection, at least one link in the chain needs to be broken. 12. Instruct students to tear any one link in their paper chain of infection. All infection control strategies are directly related to breaking at least one link in the chain of infection. Annotation: Use the paper chain template or use paper of your choice for the links. Teacher may use a different color for each link. Color coded links will make it easier to draw the student’s attention to a particular link. 7242 Health Science II Summer 2011 Page 168 2.02 Chain of Infection Activity Handout Name _______________ Date ________________ 7242 Health Science II Summer 2011 Susceptible Host Portal of Entry Mode of Transmission Portal of Exit Reservoir Causative Agent Directions: Cut out labeled strips.

CDC 2. “When” does SP apply? At all times to prevent contact with blood or other potentially infectious materials. 3. “What” situations necessitate the need for SP? Any situation where health care provider may contact: Blood or any fluid that may contain blood; Body fluids, secretions, or excretions – mucus, sputum, saliva, vomit, semen, or vaginal secretions, mucous membranes, non-intact skin, or tissue/cell specimens. 4. “What” supplies are needed for SP? Gloves, gowns, and masks/eye protections 5. “Where” should SP supplies be located before and after use? Before use, SP supplies should be stored in a clean area. After use, care must be taken to avoid contamination of clean supplies. Items should be placed in a “dirty” area. 6. “What” should be done to prevent needle sticks? When possible, safe needles or needleless devices should be used. Disposable needles must never be bent or broken after use. Never re-cap needles. Place used needles in the sharps container. 7. “When” should hands be washed? Before and after contact with any patient; after contamination with any blood, body fluid, secretion, or excretion; and immediately before donning and immediately after removing gloves. 8. “When” are gloves worn? Whenever contact with blood, body fluids, secretions, excretions, mucous membranes, tissue specimens, or non-intact skin is possible; when handling or cleaning contaminated surfaces or items; and when performing any invasive procedure. 9. “When” should mask and eye protection be worn? During procedures that may produce splashes or sprays of blood, body fluids, secretions, or excretions. 10. “When” should gowns be worn? During any procedures that are likely to cause splashing or spraying of blood, body fluids, secretions, or excretions that may contaminate clothing or uniform. 11. “What” is the proper way to handle patient care equipment? Patient care equipment should be left in the room and used only for this patient. If this is not possible, all equipment must be cleaned and disinfected before using on another patient. 12. “What” is the proper way to handle linen? Soiled linen should be placed in laundry bags to prevent contamination. Linen soiled with blood, body fluids, or excretions is placed in a special bag for contaminated linen and is usually soaked in a disinfectant prior to being laundered. 13. “What” resuscitation devices should be used? Mouthpieces should be used to avoid the need for mouth-to-mouth resuscitation. 14. “Where” the patient should be placed? The patient must be placed in a private room. 15. “What” are the results of failing to abide by SP? Chain of infection continues; failure to protect yourself, the patient, and other health care workers. 16. “What” is my employer’s responsibility? The agency must have a policy stating actions that must be taken immediately when exposure to infectious materials or injury occurs, reporting any incident, documenting any exposure incident, recording the care given, noting follow-up to the exposure incident, and identifying ways to prevent similar incidents. 17. “What” is my responsibility in SP? To follow all rules and regulations; to report any exposure immediately to supervisor; to complete necessary incident report. 18. “What” must be removed before putting on gloves? Rings – to avoid puncturing the gloves. 7242 Health Science II Summer 2011 Page 175 2.02 Donning and Removing Personal Protective Equipment Handout 1. 2. 3. 4. 5. 6. 7. 8.

EXTENDED PRECAUTIONS = STANDARD PRECAUTIONS PLUS… AIRBORNE DROPLET CONTACT PRECAUTIONS PRECAUTIONS PRECAUTIONS FACTS THAT ARE UNIQUE TO EACH TYPE OF PRECAUTION Patient’s room door must be closed. Most infection occurs within three (3) feet of the patient. Anything that comes in contact or indirect contact of the patient is contaminated. Pathogens remain suspended in the air on dust particles. Droplets are heavy and usually fall to the floor within the three feet range. Needed for diseases that can be easily transmitted by direct or indirect contact. High Efficiency Particulate (HEPA) respirators required for health care workers. Droplets come from coughing, sneezing, talking, or laughing. Diapered or incontinent patients with intestinal infections Health Care Workers (HCWs) must be fit tested for HEPA respirators HCW must wear Mask / face shield if within 3 feet of patient. Wear gown if soiling is likely. Helps prevents the spread of: rubella (measles), varicella (chicken pox), tuberculosis, (TB) shingles (herpes zoster) Helps prevent the spread of: Some bacterial and viral Influenza(s), meningitis(es) pneumonia, sinusitis, otitis media, diphtheria, pertussis, adenovirus, mumps Helps prevent the spread of gastrointestinal, respiratory, skin, or wound infections. Negative Pressure Room with frequent air exchanges required. Private room a must. FACTS THAT ALL PRECAUTIONS HAVE IN COMMON: Limit use of non-critical care equipment to a single patient / resident. Wash hands after care. Bag linen to prevent contamination of self, environment, or outside of bag. Discard infectious trash to prevent contamination of self, environment, or outside of bag by double bagging. Limit transport of patient / resident to essential purposes only. Patient / resident must wear mask appropriate for disease. 7242 Health Science II Summer 2011 Page 180 2.02 Prototype Assessment Items Note: These items illustrate the types of items used in the item bank for this objective. All items have been written to match the cognitive process of the understand verb in the objective. Questions require students to interpret, summarize or explain infection control procedures. These exact questions will not be used on the secured test, but questions in similar formats will be used. These assessment items may be used as prototypes by teachers and students to generate similar items to comprise formative assessments for you classroom. This strategy is especially helpful during the field test year when classroom item banks are not available. Results of formative assessment should be used to diagnose levels of mastery, determine if re-teaching is needed, and guide further instruction. 1.
