1. Provide small bedside bags to dispose of used tissues
2. Encourage staff to avoid coughing near patients
3. Administer antibiotics as ordered
4. Identify patients at risk
1. Fever Correct answer- The nurse identifi es that a patient has an infl ammatory
response. Which local patient adaptation supports this conclusion?
1. Fever
2. Erythema
3. Bradypnea
4. Tachycardi
3. Normal saline and apply a wet-to-damp dressing." Correct answer- A patient has a
wound that is healing by secondary intention. To best support healing of the wound, the
nurse should expect the practitioner's order to state, "Clean wound with:
1. Betadine and apply a dry sterile dressing."
2. Normal saline and cover with a gauze dressing."
3. Normal saline and apply a wet-to-damp dressing."
4. Half peroxide and half normal saline and apply a wet to dry dressing."
3. Puncture of the foot by a nail Correct answer- The nurse identifi es that the greatest
risk for a wound infection exists for a patient with a:
1. Surgical creation of a colostomy
2. First-degree burn on the back
3. Puncture of the foot by a nail
4. Paper cut on the finger
1. Cells of the skin are constantly being replaced, thereby eliminating external
pathogens Correct answer- .The nurse understands that the skin protects the body from
infections because the:
1. Cells of the skin are constantly being replaced, thereby eliminating external
pathogens
2. Epithelial cells are loosely compacted on skin, providing a barrier against pathogens
3. Moisture on the skin surface prevents colonization of pathogens
4. Alkalinity of the skin limits the growth of pathogens
,1. Stool for ova and parasites Correct answer- The nurse must collect the following
specimens. Which specimen collection does not require the use of surgical aseptic
technique?
1. Stool for ova and parasites
2. Specimen for a throat culture
3. Urine from a retention catheter

2. Contact
3. Reverse

2. Excoriated perianal areas
3. Abrasions of the skin
4. Pressure ulcers
,3. Harbor microorganisms Correct answer- The primary reason why the nurse should
avoid glued-on artificial nails is because they:
1. Interfere with dexterity of the fingers
2. Could fall off in a patient's bed

that the factor that places a patient at the greatest risk for developing an infection is:
1. Implantation of a prosthetic device
2. Presence of an indwelling urinary catheter
3. Burns more than twenty percent of the body
4. Multiple puncture sites from laparoscopic surgery
4. Immune response Correct answer- The nurse understands that a secondary line of
defense against infection is the:
1. Mucous membranes of the respiratory tract
2. Urinary tract environment
3. Integumentary system
4. Immune response
2. Administering childhood immunizations Correct answer- Which nursing action
protects the patient as a susceptible host in the chain of infection?
1. Wearing personal protective equipment

3. Recapping a used needle before discarding
4. Disposing of soiled gloves in a waste container

of infection because:
1. Pain activates the sympathetic nervous system
2. Erythema increases the flow of blood throughout the body
3. Leukocyte migration precipitates the inflammatory response
