  1. What is oxygen saturation?
    The amount of oxygen bound to hemoglobin in the blood.
  2. What is a pulse oximeter?
    A device attached to the earlobe that measure the oxygen saturation of arterial blood.
  3. What does a pulse ox measure?
    The amount of oxygen saturation in the blood
  4. What is the normal measurement?
    the amount of oxygen saturation in the blood
  5. What does it mean if it is low?
    there is impaired gas exchange or ventilation.
  6. What is capillary refill?
    the amount of time it take for blood to be refilled into the arterial capillaries.
  7. What is normal cap refill for an adult client?
    < 3seconds
  8. Does it require a physician's order?

  10. A client has a NC at 2L. What if their lips are dry?
    - Use KY jelly, no petroleum
  11. What if their mucous membranes are dry?
    use humidifier
  12. What if their oxygen saturation is 88% What about if it is 98% (what are your actions as an LVN?)
    • - if low (88%) report to charge nurse unless COPD, get an order for O2
    • - Only for a short period of time
  13. If a client is on high flow oxygen (6L) what do you need to do?
    • - Remove mask, clean skin and face Q2 hrs.
    • - only for a short period of time
  14. If someone is cyanotic, what does that imply?
    Tissues do not have enough oxygen
  15. What other VS should you do FIRST after oxygen saturation?
    Check for respiration
  16. Integumentary: hair, nails, oil, and sweat glands, blood vessels, and nerves
    function: body’s first line of defense. Protects the body from bacteria and microorganisms. Maintenance of tissue moisture, receptors for stimuli response, and regulation of body heat.
  17. Skeletal: Bones
    function: protection and movement
  18. Nervous: spinal cord, brain, nerves, skin, eyes, ears, tongue, nose
    functions: CNS- central nervous system PNS- # of receptors that gather outside info. Control of body activities and reaction to stimuli
  19. Endocrine: Pancreas, pituitary gland, adrenal gland, thyroid, glands, gonads
    functions: productions of hormones and body regulation
  20. Circulatory: blood, blood vessels, heart, lymph
    functions: transports nutrients, metabolic wastes, water, salts, and disease fighting cells
  21. Respiratory: lungs, nasal passages, bronchi, pharynx, trachea, diaphragm, bronchial tubes.
    Functions: intake of oxygen and removal of carbon dioxide from the body
  22. Digestive: Stomach, liver, teeth, tongue, pancreas, intestine, esophagus
    Functions: breakdown of food and absorption for use as energy
  23. Urinary: Kidneys, Bladder, Urethra, Adrenal Glands
    Functions: controls water intake and salt balance
  24. Lymphatic: Lymph nodes
    • Reproductive: FEMALE – Uterus, vagina, cervix, ovaries MALE- urethra, testes, prostate gland, epididymis
    • Function: Reproduction
  25. What is the function of Hgb? What does it carry? Where does this occur?
    • - Hemoglobin is iron containing oxygen transport protein in the red blood cell.
    • - It carries oxygen and iron
    • - It occurs in the gas exchange in the alveoli
  26. What is the membrane called that covers an organ? The thoracic cavity? The abdominal cavity? The joint cavity?
    • - Peritoneum : covers abdominal cavity
    • - Visceral: Organs
    • - Pleura: Thoracic cavity
    • - Peritoneal membrane: abdominal cavity
    • - Synovial membrane - joint cavity
