The flashcards below were created by user sfaltynski on FreezingBlue Flashcards. What would you like to do?


  1. Head Injury
    Trauma to the skull resulting in mild to extensive damage to the brain. Complications can include cerebral bleeding, hematomas, uncontrolled increased ICP, infections & seizures.

    • Assess orientation q 1 hr (early signs of Increased ICP is alterations in orientation).
    • Check VS (rise in BP with widening pulse pressure and slow HR can indicate increase ICP)
    • Check PERLA (pupil changes)
    • Check nose and ears of CSF Leakage. Complete Neuro Assessment.
    • Assess for HA, N/V (could be a sign)
    • -->Increased ICP can impede circulation to the brain, impede absorption of CSF, affect function of nerve
    • cells, and lead to brainstem compression & death.

    Seizure Precautions, prophylactic anticonvulsants may be administered.

    NO MORPHINE Narcotic analgesic contraindicated b/c it masks signs of ICP

    Instruct client to avoid coughing b/c may increase ICP

    Maintain HOB elevated to reduce venous pressure

  13. Levin-Single Lumen NG TUBE
    Used to removed stomach contents or provide tube feeding.

    Measure distance from tip of nose to earlobe to bottom of xiphoid process. Mark distance with tape and lubricate end with water-soluble jelly. Insert tube through nose into stomach. Offer sips of water and advance tube gently; bend the head forward.

    Observe for respiratory distress, an indication that the tube is misplaced in the lungs. Verify with xray prior to use. Aspirate gastric contents. pH usually < or equal to 4. (respiratory >5.5)

    • Check residual before intermittent feeding and q 4 hrs whith continuous feeding. Hold feeding if >100mL.
    • Instill 15-30mL before and after each med and feeding.

    Check patency q 4 hrs.
  14. Salem Sump
    Double lumen stomach tube; most frequently used for decompression with suction.

    A small vent tube within the large suction tube prevents mucosal suction damage by maintaing the pressure in open eyes at the distal end of the tube at less than 25mm Hg.

    Air vent is not to be clamped and is to be kept above level of stomach. If leakage occurs through air vent, instill 30mL of air into the air vent & irrigate the main lumen with NS.

    Hissing sound is indicative that air is freely exiting airway, purpose is to provide steady continuous suction without pulling gastric mucosa.

    Nursing care the same as with Levin NG tube.
