Question | Answer |
Meningitis (Pg. 53) | Inflammation of the meninges (membranes that protect the brain and spinal cord) |
What is the most common type of meningitis? | Viral (aseptic); resolves w/o tx |
Which type of meningitis has a high mortality rate? | Bacterial (septic), it's contagious |
Are there meningitis vaccines? (Pg. 53) | Yes 3; one is available for high-risk populations; college students |
Is there a vaccine against viral meningitis? & risks | No.
Risks to getting; mumps, measles, herpes, west nile |
Bacterial meningitis risks | Immunosuppression, invasive procedures, skull fractures, penetrating head wound, overcrowding living |
Patient complaints: | Excruciating, constant headache
Nuchal rigidity (stiff neck)
Photophobia (sensitivity to light) |
Signs/symptoms: | Fever/chills, nausea/vomiting, altered LOC, positive kernig's sign, positive brudzinski's sign, hyperactive DTR's, tachycardia, seizures, red macular rash, restless, irritable |
Positive kerning's sign: | Resistance & pain w extension of the client's leg from flexed position |
Positive brudzinski;s sign | Flexion of extremities occurring w deliberate flexion of the client's neck |
LABS | Urine, throat, nose & blood C&S
-not definitive for meningitis but can guide initial antimicrobial (broad) tx
CBC- elevated WBC's |
Dx meningitis: (pg. 55) | CSF analysis: by lumbar puncture, most definitive
-cloudy CSF (bacterial), clear (viral)
-^ WBC, protein & CSF pressure, and low glucose, |
Nursing:
precautions | Isolate as soon as suspected
-Droplet precautions; private room, con't until abx con't for 24hrs & when oral.nasal secretions no longer infectious |
Nursing:
Fever, stimuli, bed rest, ICP | Fever reducing; cool blanket
Low stimuli; low lights, quiet
Bed rest head ^ 30 degrees
If ^ ICP; avoid cough/sneeze |
Nursing:
Seizures, fluids, | Replace as indicated by labs, seizure precautions |
Medications to treat Meningitis | Ceftriaxone (Rocephin) or Cefotaxime (Claforan) in combination w/ Vancomyin
-Give until C&S available |
Med if seizures or ^ ICP | Anticonvulsants; Phenytoin (Dilantin) |
Analgesics for headaches and/or fever | Acetaminophen (tylenol) or Ibuprofen (Motrin)
-Nonopioids to avoid changing LOC |
S/S of ^ ICP (complication of meningitis) | Decreased LOC, pupillary changes, impaired extraocular movements |
Interventions to reduce ICP | Positioning & avoiding coughing/sneezing/straining |
Complication of Meningitis: | SIADH: syndrome of inappropriate ADH
-d/t abnormal stimulation of the hypothalamic area (excess secretion of ADH) |
S/S SIADH & tx | -Dilute blood, concentrated urine
-Restrict fluids and administer Demeclocycline (Declomycin) |
Septic emboli (another complication) | Can lead to DIC
-Mostly travel to hands & feet.. could develop into gangrene |
