What are the 4 Gram Positive Organisms? | Any word w/ coccus. 1. Pneumococcus. 2. Steptococcus. 3. Diplococcus. 4. Staphlococcus. |
Gram Positive Organisms Treat with (Penicillin-Type) Antibiotics- What are the three types? | 1. Amoxicillin. 2. Carbenicillin. 3. Ampicillin. |

In Gram Positive organisms if patient is alergic to penicillin antibiotics & penicillin resistant medication then what treatment do you give? | 1. Erythromycin. 2. Cephaloridine (loridine) 3. Cephalexin (Keflex). 4. Cephalothin (Keflin). |
What are the 6 Gram Negative Organisms? | 1. Pseudomonas aeruginosa 2. Haemophilus influenza 3. Klebsiella 4. Proteus 5. E.Coli 6.Serratia marcescens |
How is Gram Negative Organisms caused, where do you find it & How do you prevent it? | 1. Spread by poor hand washing & unsanitary environmental conditions. 2. Found in normal Flora for the GI tract 3. Best prevented by Hand washing. |
What are the treatments for Gram Negative Organisms? | 1. Sterptomycin 2. Gentamycin 3. Tobramycin |
What is acid-fast Bacilli? | 1. Related to TB 2. Mycobacterium TB (tubercle bacilli) |
What are the treatments for Acid-fast Bacilli? | 1. Isoniazid (INH) 2. Rifampin 3. Ethambutol 4. Streptomycin. Treatment course can last upto 2 yrs. Pt. compliance is difficult, education is very important. |

How do you treat Aerosols-Small Volume Nebulizers(SVN) | Use disposable, replace frequently/deliver same medication via an MDI. |
In Aerosols, water reservoirs should have sterile water only. Why? | Tap Water can promote an infection of pseudomonas aeruginosa. If possible, use disposable, self-contained water reservoirs. |
What are the General Prevention Guidelines? | 1. Use unit dose medication 2. Write date &time on all disposable equipment 3. Discard disposable equipment in room 4. Wipe down all equipment with 70% alcohol solution. 5. Double bag infectious disposable equipment before discarding. |

What is Universal precautions? | 1. Gloves, Mask & Gown |
What is Respiratory Isoaltion? | 1. Airborne Particles, use the N95 particular respirator , in addition to universal precaution. Pt. use mask when visitors are present or when transported outside the room for a procedure. |
What is Strict Isolation? | Gloves, gowns, masks to be used by all that enter the room. |
What is Reverse Isolation(protective)? | For immunosuppressed pts. Such as AIDS, burn trauma,etc. Also for organ transplant to provide extra protection & lower risk for infection. |
What is Enteric Isolation? | use gloves- cover any part of the body that comes in contact with blood , fecal matter, etc. |
What is Contact Isolation(wound&sking? | use gloves & gown if very close body contact. |
