| A 20 year-old female was admitted into the hospital complaining of 10 to 15 bloody mucous stools per day, fever, gastrointestinal disturbances, abdominal pain, and nausea. The preliminary O & P report went out as "Probable Entamoeba histolytica trophozoites and cysts, confirmation pending." This patient is most likely suffering from: | View Page |
| The type of health-care occupational exposure with the greatest risk of HIV transmission is: | View Page |
| Occupational Exposures HIV transmission, due to occupational exposure, occurs by: Percutaneous injury, such as a needlestick or a cut with a sharp object; Contact of mucous membrane or abraded skin with HIV-infected blood or body fluids. The risk of HIV transmission after a percutaneous exposure to HIV-infected blood is 0.3%.The risk of HIV transmission after a mucous membrane exposure to HIV-infected blood is .09%.The risk of HIV transmission after contact of abraded skin with HIV-infected blood is estimated to be less than .09%. | View Page |
| Overview Prevention of HIV exposure is the best line of defense to prevent occupational transmission of HIV as there is no vaccine available to develop specific immunity and the postexposure prophylaxis is toxic. Following appropriate workplace practices in the laboratory focus on preventing needlesticks or other sharps injuries and exposure of mucous membranes and abraded skin to HIV-infected blood or body fluids. | View Page |
| Face and Eye Protection Face shields, masks, and safety glasses protect your eyes and the mucous membranes of your nose and mouth.They must be worn whenever it is reasonably anticipated that splashing or spraying of blood or other contaminated materials may occur.Employees who wear prescription eyewear may be protected with a face shield, goggles, or with side shields attached to their glasses. | View Page |
| Gloves Gloves must be worn: when there is a reasonable chance of exposure to blood, other infectious body fluids, mucous membranes, or nonintact skin. during vascular access procedures, including phlebotomy. when handling contaminated items or surfaces.Wear only flat rings under gloves as large rings may tear gloves.Replace gloves: Between patient contacts If they are damaged or contaminated Before leaving the work area. Wash hands after removing gloves.Never wash disposable gloves. | View Page |
| The following workplace practices minimize risk of HIV exposure to mucous membranes or abraded skin: | View Page |
| The general signs and symptoms of smallpox include: | View Page |
| Agent: Pneumonic plague (Bacterium) Most likely means of dissemination: AerosolPrimary route of entry: InhalationGeneral signs and symptoms: High fever, chills, headache, coughing up of blood (hemoptysis), and toxemia, progressing rapidly to difficulty in breathing (dyspnea), and bluish discoloration of the skin and mucous membranes (cyanosis).There is another form of the disease called “bubonic plague”. While it is caused by the same organism, it is not transmissible through human contact. Pneumonic plague is transmissible through human contact. | View Page |
| The growth of the yeast-like colonies shown in the upper image was obtained on blood agar from a skin culture only in the area overlaid by virgin olive oil. The lower image is a photomicrograph of a lactophenol blue mount made from a portion of the colony. The disease associated with this fungus is: | View Page |
| Standard Precautions! Standard precautions mean that all blood and body fluids should be handled as if they were infectious and capable of transmitting disease. Standard Precautions apply to all: Blood Body fluids Secretions (except sweat) Excretions Non-intact skin Mucous membranes | View Page |
| How is HBV Spread? The virus is spread when body fluids from an individual with the Hepatitis B virus are introduced into the body of a susceptible person.This contact may occur during introduction of blood or potentially infectious body fluid: Through an opening or sore in the skin. Via a puncture with a contaminated sharp such as a needle. Through direct contact with mucous membranes that line the insides of the mouth, nose, eyes, and the genital organs. HBV is not spread through casual contact, such as handshake, or through sweat. | View Page |
| Who is infected? Patients with Hepatitis B and other bloodborne infections can appear healthy, so you can't tell whose blood is infectious.So treat all: blood body fluids secretions (except sweat) excretions non-intact skin mucous membranes as if they were infectious.That's what the term Standard Precautions means. | View Page |
| How is HIV spread? HIV is spread in the community just like HBV. Sexual contact Via a puncture with a contaminated sharp such as a needle. Through direct contact with mucous membranes that line the insides of the mouth, nose, eyes, and the genital organs. From a mother to her child | View Page |
| Gloves Must be Worn When there is a reasonable chance of exposure to blood, other infectious body fluids, mucous membranes, or nonintact skin. During vascular access procedures, including phlebotomy. When handling contaminated items or surfaces. | View Page |
| Face and Eye Protection The following protect your eyes and the mucous membranes of your nose and mouth: Face shields Masks and safety glasses They must be worn whenever it is reasonably anticipated that splashing or spraying of blood or other contaminated materials may occur.Employees who wear prescription eyewear may be protected with a face shield, goggles, or with side shields attached to their glasses. | View Page |
| Exposure Incident Even after taking all the proper precautions there is still a small chance of an exposure incident. An Exposure incident occurs when: Blood or another potentially infectious body fluid comes into direct contact with mucous membranes or non-intact skin. Parenteral exposure means: Exposure occurring as a result of piercing the skin barrier through needlesticks, cuts, or abrasions. | View Page |

| What are bloodborne pathogens? Bloodborne pathogens are infectious micro-organisms which live in the bloodstream.You can be exposed to bloodborne pathogens if you are injured with a contaminated needle.You can also be exposed if your mucous membranes, including eyes, mouth, or the inside of your nose come into contact with contaminated body fluids.

| Squamous Cells Under Phase Contrast Using phase contrast and high power the cytoplasm and nucleus appear much darker. Note the folded edge of the cytoplasm which is characteristic of squamous cells. The long, thread-like structures are mucous strands. | View Page |
| Estimating Elements The number of bacteria, yeast, crystals and mucous must be estimated. Examine 10 fields under high power (40X) magnification. Use phase-contrast if needed. Determine the average of each element found and record the findings according to the following criteria: Element fills <1/4 of each field = trace Element fills about 1/4 of each field = 1+ Element fills about 1/2 of each field = 2+ Element fills about 3/4 of each field = 3+ Element fills total field = 4+ | View Page |
