Neurologic assessment doesn't just take place in neuro units and the ED. An adequate neurologic history includes information about clinical manifestations, associated complaints, precipitating factors, progression, and familial occurrences (Box 23-1). 1 When the parasympathetic fibers are stimulated, the pupil constricts. There are 31 pairs of spinal nerves and 12 pairs of cranial nerves. The level of discrimination will vary depending on the location. This response indicates brainstem integrity. 23-8 and Table 23-3). Bates Guide to Physical Examination and History Taking. If the light is shined directly onto the pupil, glare or reflection of the light may prevent the assessor’s proper visualization. Through history taking, the caregiver gains valuable information that directs him or her to focus on certain aspects of the patient’s clinical assessment.3, • Associated activities or aggravating factors, • Stroke (arteriovenous malformation, aneurysm), • Birth injuries, congenital defects, encephalitis, meningitis, bedwetting, fainting, seizures, trauma, • Diabetes; hypertension; cardiovascular, pulmonary, kidney, liver, or endocrine disease; tuberculosis; tropical infection; sinusitis; visual problems; tumors; psychiatric disorders, • Neurologic, ear-nose-throat, dental, eye surgery, • Motor vehicle accidents, falls, blows to the head, neck or back, being knocked out, • Use of alcohol, recreational drugs, over-the-counter medications, smoking, dietary habits, sleeping patterns, elimination patterns, exercise habits, • Exposure to toxins, chemicals, fumes; occupational duties, Five major components make up the neurologic evaluation of the critically ill patient: 1) level of consciousness, 2) motor function, 3) pupillary function, 4) respiratory function, and 5) vital signs. Clinical correlates of compensated and decompensated phases of intracranial hypertension. The normal eye movement response is a conjugate, slow, tonic nystagmus, deviating toward the irrigated ear and lasting 30 to 120 seconds. assessment tool because of pathway locations. Control of eye movements occurs with interaction of three cranial nerves: 1) oculomotor (CN III), 2) trochlear (CN IV), and 3) abducens (CN VI). Arousal is the lowest level of consciousness, and observation centers on the patient’s ability to respond to verbal or noxious stimuli in an appropriate manner.5 To stimulate the patient, the nurse should begin with verbal stimuli in a normal tone. A consensual response in the blind eye produced by shining a light into the opposite eye demonstrates an intact oculomotor nerve. Sympathetic pathway disruption occurs with involvement in the brainstem. You may use the wooden end of a cotton applicator as a pen. It provides data about level of consciousness only, and it never should be considered a complete neurologic examination. Pupillary assessment: Perform pupillary assessment with special attention to size, reactivity, and shape of pupil compared with the opposite eye. Sustained extensor response of the big toe is indicative of a positive Babinski’s reflex. Mosby’s Guide to Physical Examination.

St. Louis: Mosby; 2008. Cerebral autoregulation, responsible for the control of cerebral blood flow (CBF), frequently is lost with any type of intracranial injury. Assessment of level of consciousness focuses on two areas: 1) evaluation of arousal or alertness and 2) appraisal of content of consciousness or awareness.3,5 Although universally accepted definitions for various levels of consciousness do not exist, the categories outlined in Box 23-2 are often used to describe the patient’s level of consciousness.3,4,6. The Chart has been developed to reduce the amount of variation in chart design and to improve consistency in assessment skills and interpretation of assessment findings. Neurological Assessment: Assessing Sensor y Function. Cheyne-Stokes breathing Observe for a contraction of the triceps muscle with the extension of the lower arm. Abnormal oculocephalic reflex indicates some degree of brainstem injury.3,4,12, The oculovestibular reflex is performed by a physician, often as one of the final clinical assessments of brainstem function. Chapter 23 S4, S5 • Tremors or other involuntary movements A DTR grade of 2 is normal (Fig. Do you have any numbness or tingling to any part of the body? SCORE Observed for plantar flexion, in which the toes curl. 23-3). Note: Additional documentation related to neurological assessment should be included in the nursing/ interdisciplinary notes. This response indicates brainstem integrity. Recently, however, the usefulness of the GCS has been called into question, particularly because of poor inter-rater reliability.8 Several points should be kept in mind when the GCS is used for serial assessment. Nursing Points General. Numerous invasive and noninvasive diagnostic procedures may also be performed to assist in the identification of the patient’s disorder. Placed a different object in the left hand. Also, the patient can also perform this procedure by touching the nurse finger first then their nose. After cerebral injury, the body often is in a hyperdynamic state (increased heart rate, blood pressure. Epigastric (T6-T9); midabdominal (T9-T11); hypogastric (T11-L1) As a result of the brain and brainstem influences on cardiac, respiratory, and body temperature functions, changes in vital signs could be signs of deterioration in neurologic status.3,4, A common manifestation of intracranial injury is systemic hypertension. Central neurogenic hyperventilation Any increase of pressure that exerts force down through the tentorial notch compresses the oculomotor nerve. 3. Learn neuro nursing assessment with free interactive flashcards. In the unconscious patient, assessment of ocular function and innervation of the MLF is performed by eliciting the doll’s eyes reflex. Now, ask the patient to slide the right heel along the shin bone down to the ankle. Stroking, scratching, or touching can be used as the stimulus (Table 23-2). Position of the leg with a slight degree of external rotation at the hip. From Barker E. Neuroscience Nursing: A Spectrum of Care. A thorough clinical assessment of the critically ill patient with neurologic dysfunction is imperative for the early identification and treatment of a neurologic disorder and serves as source of comparison for ongoing assessments of the patient. This test assesses a patient’s ability to discriminate between two points. Oculomotor compression associated with transtentorial herniation affects the direct light response and the consensual response in the affected pupil. Now, have the patient alternate the movement as they increase the speed. In the assessment of the unconscious patient (Box 23-7), initial efforts are directed at achieving maximal arousal of the patient. Note the patient’s ability to make judgments.

The patient is instructed to relax the extremity while the nurse performs passive range-of-motion movements and evaluates the degree of resistance. • Travel Do they affect your activities of daily living? Parasympathetic control of the pupil occurs through innervation of the oculomotor nerve (CN III), which exits from the brainstem in the midbrain area. Allergies • Severity For that reason, it is not included in this article but you can click here for our article Assessment of the Cranial Nerves. Abstract Jevon, P. (2008) Neurological Assessment Part 4 - Glasgow Coma Scale 2. Assessment of pupillary function focuses on three areas: 1) estimation of pupil size and shape, 2) evaluation of pupillary reaction to light, and 3) assessment of eye movements. Bickley LS., Szilagyi PG., (2017). The oculovestibular reflex is performed by a physician, often as one of the final clinical assessments of brainstem function. Have the patient continue walking in this manner for several yards. 6. To what does the neural synapse refer? 3rd ed. The following outline should be used for handoff of the critically ill conscious patient with neurologic dysfunction: Surgical History One critical assessment point is handoff between nurses who are caring for the patient. Continue the stimulation across the ball of the foot to the big toe. Performing the psychomotor component of the skills is directly related to understanding the theory associated with the skill. The patient should be able to respond logically and their answers should be relevant. Assessment of the patient for signs of increasing ICP is an important responsibility of the critical care nurse.
