  1. cerebrospinal fluid (CSF) for analysis
    • The adult with normal cerebrospinal fluid has no red blood cells in the CSF. The client may have small levels of white blood cells (0 to 3/mm3). Protein (15 to 45 mg/dL) and glucose (40 to 80 mg/dL) are normally present in CSF.
    • NCLEX
  2. Image Uploadclient with a head injury and notes that the client is assuming this posture
    • In decorticate posturing, the upper extremities (arms, wrists, and fingers) are flexed with adduction of the arms. The lower extremities are extended with internal rotation and plantar flexion. Decorticate posturing indicates a hemispheric lesion of the cerebral cortex.
    • NCLEX
  3. Image Upload
    client with a diagnosis of meningitis and notes that the client is assuming this posture
    • Opisthotonos is a prolonged arching of the back with the head and heels bent backward. Opisthotonos indicates meningeal irritation
    • NCLEX
  4. decerebrate posturing
    • Extension of the extremities and pronation of the arms
    • NCLEX
  5. complications associated with Bell's palsy
    • Complications of Bell's palsy include abnormal return of nerve function; "crocodile tears" (autonomic fibers reconnect to the lacrimal duct instead of the salivary glands, so the client develops excessive tearing while eating); abnormal facial movements because of reinnervation of inappropriate muscles; and spasms, atrophy, and contractures caused by incomplete motor fiber reinnervation.
    • NCLEX
  6. Alzheimer's disease characteristics
    • Dementia is the hallmark of Alzheimer's disease. Recent memory loss is one characteristic. Others include problems with abstract thinking, problems with speech (not hearing), and difficulty in performing familiar tasks.
    • NCLEX
  7. C5 spinal cord injury spinal shock findings
    • During the period of areflexia that characterizes spinal shock, the blood pressure may fall when the client sits up. The bowel and bladder often become flaccid, may become distended, and fail to empty spontaneously. Bowel sounds would be absent. Accessory muscles of respiration may become areflexic as well, diminishing respiratory excursion and oxygenation.

  8. myasthenia gravis exacerbation
    • Because dysphagia is a classic sign of myasthenia gravis exacerbation, observing how a client is able to ingest food is an important assessment.
    • NCLEX
  9. information will the nurse reinforce to the client scheduled for a lumbar puncture
    • Client preparation for lumbar puncture includes obtaining informed consent from the client. No dietary or food restrictions are required before the test. The client is told that the test will take approximately 15 to 60 minutes. The nurse needs to inform the client about the need for bedrest following the test.
    • NCLEX
  10. lumbar puncture position
    The client is assisted into a fetal position at the edge of the bed with the knees drawn up to the chest. This position allows full flexion of the spine and wider spaces between the vertebrae. The nurse should also place a pillow between the client's legs to prevent the upper leg from rolling forward and a small pillow under the client's head to support the spine in a horizontal position.NCLEX
  11. lumbar puncture position immediately after procedure
    For 1 hour after the procedure, the client assumes a prone position if able with a pillow under the abdomen to increase intra-abdominal pressure. This position retards leakage of cerebrospinal fluid. NCLEX
