Some more spinal and ICP Questions

Which nursing action should be implemented in the care of a patient who is experiencing increased ICP? A. Monitor fluid and electrolyte status astutely. B. Position the patient in a high-Fowler's position. C. Administer vasoconstrictors to maintain cerebral perfusion. D. Maintain physical restraints to prevent episodes of agitation.

A Fluid and electrolyte disturbances can have an adverse effect on ICP and must be vigilantly monitored. The head of the patient's bed should be kept at 30 degrees in most circumstances, and physical restraints are not applied unless absolutely necessary. Vasoconstrictors are not typically administered in the treatment of ICP.

You are providing care for a patient who has been admitted to the hospital with a head injury who requires regular neurologic vital signs. Which assessments are components of the patient's score on the Glasgow Coma Scale (select all that apply)? A. Eye opening B. Abstract reasoning C. Best verbal response D. Best motor response E. Cranial nerve function

A,C,D The three dimensions of the Glasgow Coma Scale are eye opening, best verbal response, and best motor response.

A patient has a nursing diagnosis of risk for ineffective cerebral tissue perfusion related to cerebral edema. An appropriate nursing intervention for the patient is a. avoiding positioning the patient with neck and hip flexion b. maintaining hyperventilation to a PaCO2 of 15 to 20 mm Hg c. clustering nursing activities to provide periods of uninterrupted rest d. routine suctioning to prevent accumulation of respiratory secretions

A. Avoiding positioning the patient with neck and hip flexion- Nursing care activities that increase ICP include hip and neck flexion, suctioning, clustering care activities, and noxious stimuli; they should be avoided or performed as little as possible in the patient with increased ICP. Lowering the PaCO2 below 20 mm Hg can cause ischemia and worsening of ICP; the PaCO2 should be maintained at 30 to 35 mm Hg.

When caring for a patient who has had a head injury, which assessment information is of most concern to the nurse? a. The blood pressure increases from 120/54 to 136/62. b. The patient is more difficult to arouse. c. The patient complains of a headache at pain level 5 of a 10-point scale. d. The patient's apical pulse is slightly irregular.

Correct Answer: B Rationale: The change in level of consciousness (LOC) is an indicator of increased ICP and suggests that action by the nurse is needed to prevent complications. The change in BP should be monitored but is not an indicator of a need for immediate nursing action. Headache is not unusual in a patient after a head injury. A slightly irregular apical pulse is not unusual. Cognitive Level: Application Text Reference: p. 1470 Nursing Process: Assessment NCLEX: Physiological Integrity

A patient with possible cerebral edema has a serum sodium level of 115 mEq/L (115 mmol/L), a decreasing level of consciousness (LOC) and complains of a headache. All of the following orders have been received. Which one should the nurse accomplish first? a. Administer acetaminophen (Tylenol) 650 mg orally. b. Administer 5% hypertonic saline intravenously. c. Draw blood for arterial blood gases (ABGs). d. Send patient to radiology for computed tomography (CT) of the head.

Correct Answer: B Rationale: The patient's low sodium indicates that hyponatremia may be causing the cerebral edema, and the nurse's first action should be to correct the low sodium level. Acetaminophen (Tylenol) will have minimal effect on the headache because it is caused by cerebral edema and increased ICP. Drawing ABGs and obtaining a CT scan may add some useful information, but the low sodium level may lead to seizures unless it is addressed quickly.

A patient admitted with a head injury has admission vital signs of temperature 98.6° F (37° C), blood pressure 128/68, pulse 110, and respirations 26. Which of these vital signs, if taken 1 hour after admission, will be of most concern to the nurse? a. Blood pressure 130/72, pulse 90, respirations 32 b. Blood pressure 148/78, pulse 112, respirations 28 c. Blood pressure 156/60, pulse 60, respirations 14 d. Blood pressure 110/70, pulse 120, respirations 30

Correct Answer: C Rationale: Systolic hypertension with widening pulse pressure, bradycardia, and respiratory changes represent Cushing's triad and indicate that the ICP has increased and brain herniation may be imminent unless immediate action is taken to reduce ICP. The other vital signs may indicate the need for changes in treatment, but they are not indicative of an immediately life-threatening process.

A patient with a head injury has an arterial blood pressure is 92/50 mm Hg and an intracranial pressure of 18 mm Hg. Which action by the nurse is appropriate? a. Document and continue to monitor the parameters. b. Elevate the head of the patient's bed. c. Notify the health care provider about the assessments. d. Check the patient's pupillary response to light.

Correct Answer: C Rationale: The patient's cerebral perfusion pressure is only 46 mm Hg, which will rapidly lead to cerebral ischemia and neuronal death unless rapid action is taken to reduce ICP and increase arterial BP. Documentation and monitoring are inadequate responses to the patient's problem. Elevating the head of the bed will lower the ICP but may also lower cerebral blood flow and further decrease CPP. Changes in pupil response to light are signs of increased ICP, so the nurse will only take more time doing this without adding any useful information.

Mechanical ventilation with a rate and volume to maintain a mild hyperventilation is used for a patient with a head injury. To evaluate the effectiveness of the therapy, the nurse should a. monitor oxygen saturation. b. check arterial blood gases (ABGs). c. monitor intracranial pressure (ICP). d. assess patient breath sounds.

Correct Answer: C Rationale: The purpose of hyperventilation for a patient with a head injury is reduction of ICP, and ICP should be monitored to evaluate whether the therapy is effective. Although oxygen saturation and ABGs are monitored in patient's receiving hyperventilation, they do not provide data about whether the therapy is successful in reducing ICP. Breath sounds are assessed, but they are not helpful in determining whether the hyperventilation is effective.

The nurse suspects the presence of an arterial epidural hematoma in the patient who experiences a. failure to regain consciousness following a head injury b. a rapid deterioration of neurologic function within 24 to 48 hours following a head injury c. nonspecific, nonlocalizing progression of alteration in LOC occurring over weeks or months d. unconsciousness at the time of a head injury with a brief period of consciousness followed by a decrease in LOC

D. An arterial epidural hematoma is the most acute neurologic emergency, and the typical symptoms include unconsciousness at the scene, with a brief lucid interval followed by a decrease in LOC. An acute subdural hematoma manifests signs within 48 hours of an injury; a chronic subdural hematoma develops over weeks or months

Metabolic and nutritional needs of the patient with increased ICP are best met with a. enteral feedings that are low in sodium b. the simple glucose available in D5W IV solutions c. a fluid restriction that promotes a moderate dehydration d. balanced, essential nutrition in a form that the patient can tolerate

D. Balanced, essential nutrition in a form that the patient can tolerate= A patient with increased ICP is in a hypermetabolic and hypercatabolic state and needs adequate glucose to maintain fuel for the brain and other nutrients to meet metabolic needs. Malnutrition promotes cerebral edema, and if a patient cannot take oral nutrition, other means of providing nutrition should be used, such as tube feedings or parenteral nutrition. Glucose alone is not adequate to meet nutritional requirements, and 5% dextrose solutions may increase cerebral edema by lowering serum osmolarity. Patients should remain in a normovolemic fluid state with close monitoring of clinical factors such as urine output, fluid intake, serum and urine osmolality, serum electrolytes, and insensible losses.

When assessing the body function of a patient with increased ICP, the nurse should initially assess a. corneal reflex testing b. extremity strength testing c. pupillary reaction to light d. circulatory and respiratory status

D. Circulatory and respiratory status- Of the body functions that should be assessed in an unconscious patient, cardiopulmonary status is the most vital function and gives priorities to the ABCs (airway, breathing, and circulation)

A client with a head injury is being monitored for increased intracranial pressure (ICP). His blood pressure is 90/60 mmHG and the ICP is 18 mmHg; therefore his cerebral perfusion pressure (CPP) is: a.) 52 mm Hg b.) 88 mm Hg c.) 48 mm Hg d.) 68 mm Hg

a.) 52 mm Hg Rationale: MAP=Systolic+Diastolic(x2)/3 90+60(2)=210 90+120=210 210/3=70 MAP=70 CCP=MAP-ICP 70-18=52 CCP=52

The nurse is caring for a client with a closed head injury. Which of the following would contribute to intracrainal hypertension? a.) hypoventilation b.) elevating the head of the bed c.) hypernatremia d.) quiet darkened environnent

a.) hypoventilation Rationale: Hypoventilation leads to vasodilation and increased intracranial pressure.

A patient is admitted with a subacute subdural hematoma. The nurse realizes this patient will most likely be treated with: a.) Emergency craniotomy. b.) Elective draining of the hematoma. c.) Burr holes to remove the hematoma. d.) Removal of the affected cranial lobe.

b.) Elective draining of the hematoma

Which of the following conditions indicates that spinal shock is resolving in a client with C7 quadriplegia? a.) Absence of pain sensation in chest b.) Spasticity c.) Spontaneous respirations d.) Urinary continence

b.) Spasticity Rationale: Spasticity, the return of reflexes, is a sign of resolving shock. Spinal or neurogenic shock is characterized by hypotension, bradycardia, dry skin, flaccid paralysis, or the absence of reflexes below the level of injury. The absence of pain sensation in the chest doesn't apply to spinal shock. Spinal shock descends from the injury, and respiratory difficulties occur at C4 and above.

The patient reports falling when he his foot got "stuck" on a crack in the sidewalk, hitting his head when he fell, and "passing out". The paramedics found the patient walking at the scene and talking before transporting the patient to the hospital. In the emergency department, the patient starts to lose consciousness. This is a classic scenario for which complication? A. Epidural hematoma B. Subdural hematoma C. Subarachnoid bleed D. Diffuse axial inju

A Epidural hematoma often results from a linear fracture crossing a major artery in the dura. The classic sign is an initial period of unconsciousness at the scene and a brief lucid interval followed by a decrease in LOC. A subdural hematoma often results from injury to the brain and veins and develops more slowly. The classic sign or symptom of subarachnoid hemorrhage is a patient describing "the worst headache of my life." Diffuse axonal injury is widespread axonal damage occurring after a traumatic brain injury.

A patient with ICP monitoring has pressure of 12 mm Hg. The nurse understand that this pressure reflects a. a severe decrease in cerebral perfusion pressure b. an alteration in the production of CSF c. the loss of autoregulatory control of ICP d. a normal balance between brain tissue, blood, and CSF

A patient with ICP monitoring has pressure of 12 mm Hg. The nurse understand that this pressure reflects a. a severe decrease in cerebral perfusion pressure b. an alteration in the production of CSF c. the loss of autoregulatory control of ICP d. a normal balance between brain tissue, blood, and CSF

The nurse is monitoring a patient for increased ICP following a head injury. Which of the following manifestations indicate an increased ICP (select all that apply) a. fever b. oriented to name only c. narrowing pulse pressure d. dilated right pupil > left pupil e. decorticate posturing to painful stimulus

A, B, D, E- The first sign of increased ICP is a change in LOC. Other manifestations are dilated ipsilateral pupil, changes in motor response such as posturing, and fever, which may indicate pressure on the hypothalamus. Changes in vital signs would be an increased systolic BP with widened pulse pressure and bradycardia

A patient with an intracranial problem does not open his eyes to any stimulus, has no verbal response except moaning and muttering when stimulated, and flexes his arm in response to painful stimuli. The nurse records the patients GCS score as a. 6 b. 7 c. 9 d. 11

B. 7- no opening of eyes = 1; incomprehensible words= 2, flexion withdrawal = 4 Total = 7

The nurse recognizes the presence of Cushing's triad in the patient with a. Increased pulse, irregular respiration, increased BP b. decreased pulse, irregular respiration, increased pulse pressure c. increased pulse, decreased respiration, increased pulse pressure d. decreased pulse, increased respiration, decreased systolic BP

B. Cushing's triad consists of three vital sign measures that reflect ICP and its effect on the medulla, the hypothalamus, the pons, and the thalamus. Because these structures are very deep, Cushing's triad is usually a late sign of ICP. The signs include an increasing systolic BP with a widening pulse pressure, a bradycardia with a full and bounding pulse, and irregular respirations.

The nurse plans care for a patient with increased ICP with the knowledge that the best way to position the patient is to a. keep the head of the bed flat b. elevate the head of the bed to 30 degrees c. maintain patient on the left side with the head supported on a pillow d. use a continuous rotation bed to continuously change patient position

B. elevate the head of the bed to 30 degrees

A patient with increased ICP has mannitol (Osmitrol) prescribed. Which option is the best indication that the drug is achieving the desired therapeutic effects? A. Urine output increases from 30 mL to 50 mL/hour. B. Blood pressure remains less than 150/90 mm Hg. C. The LOC improves. D. No crackles are auscultated in the lung fields.

C LOC is the most sensitive indicator of ICP. Mannitol is an osmotic diuretic that works to decrease the ICP by plasma expansion and an osmotic effect. Although the other options may indicate a therapeutic effect of a diuretic, they are not the main reason this drug is given.

While the nurse performs ROM on an unconscious patient with increased ICP, the patient experiences severe decerebrate posturing reflexes. The nurse should a. use restraints to protect the patient from injury b. administer CNS depressants to lightly sedate the patient c. perform the exercises less frequently because posturing can increase ICP d. continue the exercises because they are necessary to maintain musculoskeletal function

C. Perform the exercises less frequently because posturing can increase ICP- If reflex posturing occurs during ROM or positioning of the patient, these activities should be done less frequently until the patient's condition stabilizes, because posturing can case increases in ICP. Neither restraints nor CNS depressants would be indicated.

When the nurse applies a painful stimulus to the nailbeds of an unconscious patient, the patient responds with internal rotation, adduction, and flexion of the arms. The nurse documents this as a. decorticate posturing. b. decerebrate posturing. c. localization of pain. d. flexion withdrawal.

Correct Answer: A Rationale: Internal rotation, adduction, and flexion of the arms in an unconscious patient is documented as decorticate posturing. Extension of the arms and legs is decerebrate posturing. Because the flexion is general, it does not indicate localization of pain or flexion withdrawal.

A patient has a systemic blood pressure (BP) of 120/60 mm Hg and an intracranial pressure of 24 mm Hg. The nurse determines that the cerebral perfusion pressure (CPP) of this patient indicates a. high blood flow to the brain. b. normal intracranial pressure (ICP). c. impaired brain blood flow. d. adequate cerebral perfusion.

Correct Answer: C Rationale: The patient's CPP is 56, below the normal of 70 to 100 mm Hg and approaching the level of ischemia and neuronal death. The patient has low cerebral blood flow/perfusion. Normal ICP is 0 to 15 mm Hg. Cognitive Level: Application Text Reference: p. 1468 Nursing Process: Assessment NCLEX: Physiological Integrity

When evaluating an ABG from a client with a subdural hematoma, the nurse notes the PaCO2 is 30 mm Hg. Which of the following responses best describes this result? a.) Appropriate; lowering carbon dioxide (CO2) reduces intracranial pressure (ICP). b.) Emergent; the client is poorly oxygenated. c.) Normal d.) Significant; the client has alveolar hypoventilation.

a.) Appropriate; lowering carbon dioxide (CO2) reduces intracranial pressure (ICP). Rationale: A normal PaCO2 value is 35 to 45 mm Hg. CO2 has vasodilating properties; therefore, lowering PaCO2 through hyperventilation will lower ICP caused by dilated cerebral vessels. Oxygenation is evaluated through PaO2 and oxygen saturation. Alveolar hypoventilation would be reflected in an increased PaCO2.

The nurse is caring for the client with increased intracranial pressure. The nurse would note which of the following trends in vital signs if the ICP is rising? a.) Increasing temperature, increasing pulse, increasing respirations, decreasing blood pressure. b.) Increasing temperature, decreasing pulse, decreasing respirations, increasing blood pressure. c.) Decreasing temperature, decreasing pulse, increasing respirations, decreasing blood pressure. d.) Decreasing temperature, increasing pulse, decreasing respirations, increasing blood pressure.

b.) Increasing temperature, decreasing pulse, decreasing respirations, increasing blood pressure. Rationale: A change in vital signs may be a late sign of increased intracranial pressure. Trends include increasing temperature and blood pressure and decreasing pulse and respirations. Respiratory irregularities also may arise.

A client admitted to the hospital with a subarachnoid hemorrhage has complaints of severe headache, nuchal rigidity, and projectile vomiting. The nurse knows lumbar puncture (LP) would be contraindicated in this client in which of the following circumstances? a.) Vomiting continues b.) Intracranial pressure (ICP) is increased c.) The client needs mechanical ventilation d.) Blood is anticipated in the cerebralspinal fluid (CSF)

b.) Intracranial pressure (ICP) is increased Rationale: Sudden removal of CSF results in pressures lower in the lumbar area than the brain and favors herniation of the brain; therefore, LP is contraindicated with increased ICP. Vomiting may be caused by reasons other than increased ICP; therefore, LP isn't strictly contraindicated. An LP may be preformed on clients needing mechanical ventilation. Blood in the CSF is diagnostic for subarachnoid hemorrhage and was obtained before signs and symptoms of ICP.

The client with an old C6 spinal cord injury complains of suddenly being too warm, with nasal congestion and a very red face. What is your next assessment? a.) temperature b.) blood pressure c.) input and output for previous 8 hours d.) bowel for impaction

b.) blood pressure Rationale: This is autonomic dysreflexia and is usually associated with hypertension. Sit them up quickly.

A patient with increased ICP is being monitored in the intensive care unit (ICU) with a fiberoptic catheter. Which order is a priority for you? A. Perform hourly neurologic checks. B. Take a complete set of vital signs. C. Administer the prescribed mannitol (Osmitrol). D. Give an H2-receptor blocker.

c he priority is to treat the known existing problem, and mannitol is the only thing that can do that. Because the patient is having the current pressure measured with objective numbers, treating the known problem is a priority over additional assessments. H2-blockers are given when corticosteroids are administered to help prevent gastrointestinal bleeding, but they are not a priority compared with the treatment of ICP.

During an assessment of a patient's motor status with the Glasgow Coma scale, the patient assumes a posture of abnormal flexion. The nurse would document this finding as: a.) 5 b.) 4 c.) 3 d.) 2

c.) 3

A client with a spinal cord injury is exhibiting poikilothermia. Which of the following would be appropriate to include in this client's plan of care? a.) Provide good perineal care. b.) Pass nasogastric tube to decompress stomach. c.) Keep client warm with extra blankets. d) Stimulate the anal-rectal reflex.

c.) Keep client warm with extra blankets. Rationale: Poikilothermia is a loss of temperature control and is dangerous because the client's body temperature will depend upon the temperature in the environment. The client needs to be kept warm and monitored carefully to avoid thermal injuries from passive warming devices.

Which of the following signs and symptoms of increased ICP after head trauma would appear first? a.) Bradycardia b.) Large amounts of very dilute urine c.) Restlessness and confusion d.) Widened pulse pressure

c.) Restlessness and confusion Rationale: The earliest symptom of elevated ICP is a change in mental status. Bradycardia, widened pulse pressure, and bradypnea occur later. The client may void large amounts of very dilute urine if there's damage to the posterior pituitary.

A client with a subdural hematoma becomes restless and confused, with dilation of the ipsilateral pupil. The physician orders mannitol for which of the following reasons? a.) To reduce intraocular pressure b.) To prevent acute tubular necrosis c.) To promote osmotic diuresis to decrease ICP d.) To draw water into the vascular system to increase blood pressure

c.) To promote osmotic diuresis to decrease ICP Rationale: Mannitol promotes osmotic diuresis by increasing the pressure gradient, drawing fluid from intracellular to intravascular spaces. Although mannitol is used for all the reasons described, the reduction of ICP in this client is a concern.

A pediatric client is admitted to the neuro ICU with a closed-head injury sustained after falling out of a tree house. The mechanisms of injury this young client most likely sustained would be: a.) Acceleration b.) Penetrating c.) Rotational d.) Deceleration

d.) Deceleration Rationale: Deceleration injury occurs when the brain stops rapidly in the cranial vault. As the skull ceases movement, the brain continues to move until it hits the skull. The force of deceleration causes injury at the site of impact. An example of this is a victim of a fall.

A 22-year-old client with quadriplegia is apprehensive and flushed, with a blood pressure of 210/100 and a heart rate of 50 bpm. Which of the following nursing interventions should be done first? a.) Place the client flat in bed b.) Assess patency of the indwelling urinary catheter c.) Give one SL nitroglycerin tablet d.) Raise the head of the bed immediately to 90 degrees

d.) Raise the head of the bed immediately to 90 degrees Rationale: Anxiety, flushing above the level of the lesion, piloerection, hypertension, and bradycardia are symptoms of autonomic dysreflexia, typically caused by such noxious stimuli such as a full bladder, fecal impaction, or decubitus ulcer. Putting the client flat will cause the blood pressure to increase even more. The indwelling urinary catheter should be assessed immediately after the HOB is raised. Nitroglycerin is given to reduce chest pain and reduce preload; it isn't used for hypertension or dysreflexia.

A client with a C4 spinal injury would most likely have which of the following symptoms? a.) Aphasia b.) Hemiparesis c.) Paraplegia d.) Tetraplegia

d.) Tetraplegia Rationale: Tetraplegia occurs as a result of cervical spine injuries. Paraplegia occurs as a result of injury to the thoracic cord and below.
