(Most basic concept) - correct answer Bacteria What other organisms cause illness? - correct answer Fungus, parasites, bacteria/virus (most likely seen in hospitals), and protozoa. How does the chain of infection go? (6 steps) - correct answer Infectious agent to reservoir to portal of exit to mode of transmission to portal of entry to host. Put the stages of infection in the correct order. A. Illness stage B. Convalescence C. Incubation period D. Prodromal stage - correct answer C D A B What is the interval when the pt manifests SXS specific to type of infection (Ex: Strep throat is manifested by sore throat, pain, and swelling)? - correct answer Illness stage What is the interval when acute symptoms of infection disappear? - correct answer Convalescence stage What is the interval between entrance of pathogen into body and appearance of first symptoms (Ex: Chickenpox, 14-16 days after exposure, common cold, 1-2 days, influenza, 1-4 days)? - correct answer Incubation stage What is the interval from onset of nonspecific SXS to more specific symptoms (Ex: Herpes simplex begins with itching and tingling at the site before the lesion appears)? - correct answer Prodromal stage The pt and the nurse are discussing Rickettsia rickettsii--Rocky Mountain spotted fever.

Dons gloves when wearing artificial nails C. Disposes an uncapped needle in the designated container D. Wears eyewear when emptying the urinary drainage bag - correct answer C. What is the term for coming from microorganisms found outside the individual such as Salmonella? - correct answer Exogenous What is the term for when part of the flora becomes altered and an overgrowth results? - correct answer Endogenous What is a type of HAI caused by an invasive diagnostic or therapeutic procedure? - correct answer Iatrogenic What develops when broad-spectrum antibiotics eliminate a wide range of normal flora organisms, not just those causing infection (An infection on top of the previous infection that is already occurring)? - correct answer Suprainfection What is MDRO? - correct answer Multi-Drug Resistant Organism What is the term for when there are very few/little organisms are present? Ex: Hand hygiene, barrier techniques, and routine environmental cleaning. - correct answer Medical asepsis (Clean technique) What is the term for when they are no organisms present and this prevents contamination of an open wound, serves to isolate an operative area from the unsterile environment, and maintains a sterile field for surgery? - correct answer Surgical asepsis (Sterile technique) What does CAUTI mean? - correct answer Catheter Associated UTI What does SSI mean? - correct answer Surgical Site Infection What does CLABSI mean? - correct answer Central Line Associated Blood Stream Infection The nurse is caring for a pt who has cultured positive for Clostridium difficile. Which action will the nurse take NEXT? A. Instruct assistive personnel to use soap and water rather than sanitizer B. Wear a N95 respirator when entering the pt room C. Place the pt on droplet precautions D. Teach the pt cough etiquette - correct answer A. The nurse is caring for a pt that has a blood born pathogen. The nurse splashes blood above the glove to intact skin while discontinuing an IV infusion. Which step(s) will the nurse take NEXT? A. Obtain an alcohol swab, remove the blood with an alcohol swab, and continue care B. Immediately wash the site with soap and running water, and seek guidance from the manager C. Do nothing; accidentally getting splashed with blood happens frequently and is a part of the job D. Delay washing of the site until the nurse is finished providing care to the pt - correct answer B. What precautions focus on diseases that are transmitted by large droplets expelled into the air and by being within 3 ft to a pt? - correct answer Droplet precautions What precautions are used for direct and indirect contact with its and their environment? - correct answer Contact precautions What precautions focus on diseases that are transmitted by smaller droplets, which remain in the air for longer periods of time? - correct answer Airborne precautions What precautions focus on a very limited pt population that protects the pt against outside infections and trying to protect their immune responses? - correct answer Protective precautions or reverse isolation What does it mean to clean? - correct answer To remove organic material or inorganic material from objects and surfaces. What does it mean to disinfect? - correct answer It eliminates many or all microorganisms, with the exception of material spores, from inanimate objects. What does it mean to sterilize? - correct answer Eliminates or destroys all forms of microbial life, including spores. What is a pressure ulcer that is non-blanchable erythema of intact skin usually over bony prominences. When palpated the erythema does not go away (Look @ temp-cold/warm, turgor, pain/loss of sensation, and texture of skin)? - correct answer Stage I What is a pressure ulcer that has partial-thickness skin loss with exposed dermis (non-intact skin) presenting as a shallow open ulcer with a red pink wound bed? - correct answer Stage II What is a pressure ulcer that has full-thickness tissue loss and subcutaneous fat may be visible but bone, tendon, and muscle are not expose? - correct answer Stage III What is a pressure ulcer that has full-thickness tissue loss with exposed bone, tendon, or muscle that could increase the pts risk of developing osteomyelitis? - correct answer Stage IV What is a pressure ulcer that is obscured full-thickness tissue loss and skin loss in which the base of the ulcer is covered by slough and/or eschar in the wound bed? - correct answer Unstageable What is a pressure ulcer that is persistent non-blanchable deep red, maroon, or purple discoloration of skin or blood-filled blister due to damage of underlying soft tissue from pressure and/or shear? - correct answer Suspected deep tissue injury (sDTI) Name some risk factors for skin integrity. - correct answer Impaired sensory perception, impaired mobility, alteration in LOC, shear, friction, and moisture (occurs with pts in fowler's or semi-fowler's position). What is the sliding movement of skin and subcutaneous tissue while the underlying muscle and bone are stationary? - correct answer Shear What is the force of 2 surfaces moving across one another such as the mechanical force exerted when skin is dragged across a coarse surface such as bed linens? - correct answer Friction What is the presence and duration of moisture on the skin increases the risk of ulcer formation (tends to be from incontinence, but can also occur from sweat, blood, wound drainage, etc.)? - correct answer Moisture What is a primary intention? - correct answer A clean surgical incision is an example of a wound with little tissue loss. This heals from the outside, in. What is secondary intention? - correct answer A wound involving loss of tissue such as burn, pressure ulcer, or severe laceration. This heals from the inside, out. What are the stages of full-thickness wound repair? - correct answer Hemostasis, inflammatory phase, proliferative phase, and maturation. What is the hemostasis phase? - correct answer Injured blood vessels constrict, and platelets gathers to stop bleeding. What is the inflammatory phase? - correct answer Damaged tissue and mast cells secrete histamine, resulting in vasodilation of surrounding capillaries and movement/migration of serum and WBCs into the damaged tissues. What is the proliferative phase? - correct answer This is where the new cells begin to maintain tissue integrity. What is the maturation phase? - correct answer It is the final stage of healing, sometimes takes place for more than a year, depending on the depth and extent of the wound.
