1. What is pulse oximetry and what is a normal finding? What could cause an abnormal
reading?
Pulse oximetry is a noninvasive, measurement of the oxygen saturation of the blood.
The expected reference range is between 95% and 100% but a range between 91% and 100% is
acceptable.
Values can be slightly lower for older adult clients and clients with dark skin. Additional reasons
for low readings include hypothermia, poor peripheral blood flow, too much light (sun, infrared
lamps), low hemoglobin levels, jaundice, movement, edema and nail polish.
2. A nurse is caring for a client with a diabetic ulcer which has a bacterial infection. Identify
the lab values the nurse will review to monitor for infection.
The nurse will monitor the client's Leukocytosis (WBCs greater than 10,000/µL), Increases in the
specific types of WBCs on differential (left shift = an increase in neutrophils), Elevated
erythrocyte sedimentation rate (ESR) over 20 mm/hr, an increase indicates an active
inflammatory process or infection.
3. A nurse in the treatment plan of a client with a stage III wound has an order to irrigate the
wound site. Identify nursing measures to safely clean and irrigate the wound for this client.
Irrigate the wound using a piston syringe or a sterile straight catheter for deep wounds with small
openings. Apply 5 to 8 psi of pressure. A 30 to 60 mL syringe with a 19‑gauge needle provides
approximately 8 psi. Use normal saline, lactated Ringer’s, or an antibiotic/antimicrobial solution.
Cleanse from the least contaminated toward the most contaminated, use gentle friction when
cleansing or applying solutions to the skin to avoid bleeding or further injury to the wound,
isotonic solutions is the preferred cleansing agents for wound cleaning. Never use the same gauze
to cleanse across an incision or wound more than once. Do not use cotton balls and other products
that shed fibers.
4. A nurse is rounding on her clients and notes her client diagnosed with fluid volume deficit
has an infiltrated intravenous (IV) access site. Identify three (3) clinical manifestations of
IV infiltration.
Clinical manifestations of IV infiltration include Pallor, local swelling at the site, and decreased
skin temperature around the site.
