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


  1. DX lumbar puncture
    • Purpose: analyze CSF diagnose infection, hemorrhage, obstruction to CSF to
    • contraindicated: any infection at insertion site and incr ICP
    • apply emla 1 hr cream, sometimes consciously sedation
    • position them appropriately- hold the patient
    • needle in back L3-L$
    • strict aspestic tech
    • collect 3 tubes w/ 2-3ml CSF
    • analyze glucose/protein-, culture and sensitivity- last tube most clean
    • GLUCOSE: bacteria will feed on the glucose- low
    • Protein- will be high if bacteria
  2. Positioning for lumbar puncture
    • sit the baby up to back open- have them hold still
    • older kids lie them on their side- have them hold still...it should not hurt. feel pinch
  3. Lumbar puncture: Nursing
    family/patient education: reduces fear and apprehension- explain what to expect during procedure

    • Nursing: Post procedure care:
    • lie flat for 30min- 1 hr as order or according to policy- bc we don't want air to go up to the brain. sometimes air gets introduce inside
    • increase fluids- to incr CSF
    • comfort measure and analgesia for headaches
    • encourage parents to comfort child
  4. DX testing
    • CT
    • Nursing
    • - protect from radiation exposure
    • - sedation necessary for children who cannot hold still

    • MRI
    • Nursing:
    • -assess for internal or external metal devices
    • - sedation for children who can't hold still
    • - assess for allergies if contrast is order
    • - encourage fluids if not contraindicated

    • Cerebreal angiography: visual of brain blood vessels
    • - assess allergy bc contrast
    • - after procedure- HOB up and incre fluids if u can

    • Head and Neck injury
    • nursing - helps identify ICP, skull defect etc

    • PET- similar to MRI/CT
    • EEG
  5. Febrile seizure
    • most common seizure of childhood
    • defined as generalized seizure lasting < 15 minutes that occurence in 24 hour period and is associated with fever without any CNS infection.
    • most often affects children <5 yrs 3m-5y
    • self limiting seizure
    • rapid rising seizure
    • most in boys
    • should have follow up with HCP
    • Complications are rare: motor coordination deficit, intellectual disability, behavior problems
  6. Febrile seizure; therapeutic management
    • HCP will:
    • determine cause of fever
    • provide fever control
    • seizure medications
    • - PO or rectal diazepam? generic name rectal if seizing
    • - safe and effective in terminating febrile seizure activity
    • - used in high risk children or those with anxious parents
  7. Febrile seizure: Assessment
    • monitor VS, incr risk with rapid raise in temp
    • 102.2 or 39c
    • S/S:
    • - stiffening of entire body, jerkingof arms and legs
    • - complete lack of response to any stimuli, loss of consciousness
    • - eyes deviated, staring, rolling back, moving back and forth
    • - urinary incontenience
    • - nosey breathing, labor, slower than normal
    • Documentation:
    • - onset and duration of procedure
    • - characterics of patients after the seizure: LOC, apnea, cynanosis, motor activity, incontinence
    • collect and document complete Hx as dx is based on hx and PE
    • determine source of fever
  8. febrile seizure: nursing management
    • initiates safety/seizure precautions: pad side rails, remove objects that can cause injury, have suction and o2 equipment available
    • parental support and reassurance
    • Provide family education:
    • - controlling fever- give med when suspected fever comes
    • - safety during seizure activity
    • - med teaching: po or rectal diazepam
    • - when to call HCP
    • - when to call 911
    • - all seizure activity needs prompted medical attention
  9. FS home care
    • family education: safety is key
    • main goals:
    • - protect airway and patient safety
    • - remain calm and with child
    • - remove objects from mouth
    • - remove funiture of sharp objects
    • - place child on side or abd clear mouth or suction bulb
    • - perform jaw thrust or chin lift for noisy or labored breathing
    • - do not restrain or try to stop seizure movements
    • - do not hold tongue or put anything in mouth
    • - document length, movement see other slide
    • Control fever and not PO meds until the child is stable and conscious
    • - give antipyretics- acteminophen suppositories
    • - remove clothing
    • - cool wash cloth neck and face
    • - sponge bath do not immerse seizing child in tub
  10. FS when to call 911
    • Call HCP:
    • after a brief repeated febrile seizure and follow home care

    • Call 911:
    • - serious trouble breathing, stops breathing
    • - any injury occur
    • - this is the first one
    • - seizure last more than 5 mins
    • - cyanosis
    • - unresponsive to painful stimuli after seizure
  11. Intracanial Infections: meningitis

    • associated abnormalites

    • after birth observe and document spontaneous movements of lower extremities and for bladder/bowel disfunction
  31. Spina bifida thera man
    • utero: surgery fetoscopy surgery
    • after birth
    • surgical correction or closure of defect within 12-48 hrs
    • shunt placement hydrocephalus
  32. neural tube disorder interventions 2

    • encourage folic acid
    • provide emotional support both pre op and post op
    • preopertive position on abdomen moist dressing on it
    • - obtain head CS, monitor I&O, monitor for infection, monitor bladder/bowel function
    • post op
