Which patient is at highest risk for a spinal cord injury? 1. 18-year-old male with a prior arrest for driving while intoxicated (DWI) 2. 20-year-old female with a history of substance abuse 3. 50-year-old female with osteoporosis 4. 35-year-old male who coaches a soccer team

Correct Answer: 1 Rationale: The three major risk factors for spinal cord injuries (SCI) are age (young adults), gender (higher incidence in males), and alcohol or drug abuse. Females tend to engage in less risk-taking behavior than young men.

A patient with a spinal cord injury is recovering from spinal shock. The nurse realizes that the patient should not develop a full bladder because what emergency condition can occur if it is not corrected quickly? 1. autonomic dysreflexia 2. autonomic crisis 3. autonomic shutdown 4. autonomic failure

Correct Answer: 1 Rationale: Be attuned to the prevention of a distended bladder when caring for spinal cord injury (SCI) patients in order to prevent this chain of events that lead to autonomic dysreflexia. Track urinary output carefully. Routine use of bladder scanning can help prevent the occurrence. Other causes of autonomic dysreflexia are impacted stool and skin pressure. Autonomic crisis, autonomic shutdown, and autonomic failure are not terms used to describe common complications of spinal injury associated with bladder distension.

A patient has the nursing diagnosis of Impaired Swallowing and complains of frequent heartburn. What is the most appropriate action by the nurse? 1. Assist the patient in maintaining a sitting position for 30 minutes after the meal. 2. Teach the patient the "chin tuck" technique when swallowing. 3. Check the patient's mouth for pocketing of food. 4. Assist the patient to a 90-degree sitting position, or as high as tolerated, during meals.

Correct Answer: 1 Rationale: Keeping the patient upright for a time after the meal will help prevent food from being regurgitated back into the esophagus. The position of the patient during the meals as well as teaching the "chin tuck" technique will assist with the swallowing mechanism, but will not help with regurgitation. Pocketing food does not cause regurgitation.

An unconscious patient receiving emergency care following an automobile crash accident has a possible spinal cord injury. What guidelines for emergency care will be followed? Select all that apply. 1. Immobilize the neck using rolled towels or a cervical collar. 2. The patient will be placed in a supine position 3. The patient will be placed on a ventilator. 4. The head of the bed will be elevated. 5. The patient's head will be secured with a belt or tape secured to the stretcher.

Correct Answer: 1,2,5 Rationale: In the emergency setting, all patients who have sustained a trauma to the head or spine, or are unconscious should be treated as though they have a spinal cord injury. Immobilizing the neck, maintaining a supine position and securing the patient's head to prevent movement are all basic guidelines of emergency care. Placement on the ventilator and raising the head of the bed will be considered after admittance to the hospital.

A post-stroke patient is going home on oral Coumadin (warfarin). During discharge teaching, which statement by the patient reflects an understanding of the effects of this medication? 1. "I will stop taking this medicine if I notice any bruising." 2. "I will not eat spinach while I'm taking this medicine." 3. "It will be OK for me to eat anything, as long as it is low fat." 4. "I'll check my blood pressure frequently while taking this medication."

Correct Answer: 2 Rationale: Warfarin is a vitamin K antagonist. Green, leafy vegetables contain vitamin K, and will therefore interfere with the therapeutic effects of the drug. Bruising is a common side effect, and the drug should not be stopped unless by prescriber order. Low-fat foods do not interfere with warfarin therapy, which is not prescribed to affect the blood pressure.

A patient with a spinal cord injury was given IV Decadron (dexamethasone) after arriving in the emergency department. The patient also has a history of hypoglycemia. During the hospital stay, the nurse would expect to see which of the following? 1. increased episodes of hypoglycemia 2. possible episodes of hyperglycemia 3. no change in the patient's glycemic parameters 4. both hyper- and hypoglycemic episodes

Correct Answer: 2 Rationale: A common side effect of corticosteroids is hyperglycemia. Stress as well as the medication could cause this person to have periods of elevated blood sugars.

The nurse is educating a patient and the family about different types of stabilization devices. Which statement by the patient indicates that the patient understands the benefit of using a halo fixation device instead of Gardner-Wells tongs? 1. "I will have less pain if I use the halo device." 2. "The halo device will allow me to get out of bed." 3. "I am less likely to get an infection with the halo device." 4. "The halo device does not have to stay in place as long."

Correct Answer: 2 Rationale: A halo device will allow the patient to be mobile since it does not require weights like the Gardner-Wells tongs. The patient's pain level is not dependant on the type of stabilization device used. The patient does not have a great risk of infection with the Garnder-Wells tongs; both devices require pins to be inserted into the skull. The time required for stabilization is not dependant on the type of stabilization device used.

A patient with a spinal cord injury at the T1 level complains of a severe headache and an "anxious feeling." Which is the most appropriate initial reaction by the nurse? 1. Try to calm the patient and make the environment soothing. 2. Assess for a full bladder. 3. Notify the healthcare provider. 4. Prepare the patient for diagnostic radiography.

Correct Answer: 2 Rationale: Autonomic dysreflexia occurs in patients with injury at level T6 or higher, and is a life-threatening situation that will require immediate intervention or the patient will die. The most common cause is an overextended bladder or bowel. Symptoms include hypertension, headache, diaphoresis, bradycardia, visual changes, anxiety, and nausea. A calm, soothing environment is fine, though not what the patient needs in this case. The nurse should recognize this as an emergency and proceed accordingly. Once the assessment has been completed, the findings will need to be communicated to the healthcare provider.

A lumbar puncture (LP) is done on a patient to rule out a spinal cord tumor. The cerebrospinal fluid (CSF) is xanthochromic, has increased protein, no cells, and clots immediately. What syndrome do these findings describe? 1. Glasgow's syndrome 2. Froin's syndrome 3. cord tumor syndrome 4. reflex syndrome

Correct Answer: 2 Rationale: Froin's syndrome is seen with spinal cord tumors. A lumbar puncture, x-rays, CT scans, MRI, and myelogram are all common tests that are used to diagnose a spinal cord tumor. Glasgow's syndrome, cord tumor syndrome, and reflex syndrome are not terms associated with the symptoms of spinal cord tumor described.

The patient is admitted with injuries that were sustained in a fall. During the nurse's first assessment upon admission, the findings are: blood pressure 90/60 (as compared to 136/66 in the emergency department), flaccid paralysis on the right, absent bowel sounds, zero urine output, and palpation of a distended bladder. These signs are consistent with which of the following? 1. paralysis 2. spinal shock 3. high cervical injury 4. temporary hypovolemia

Correct Answer: 2 Rationale: Spinal shock is common in acute spinal cord injuries. In addition to the signs and symptoms mentioned, the additional sign of absence of the cremasteric reflex is associated with spinal shock. Lack of respiratory effort is generally associated with high cervical injury. The findings describe paralysis that would be associated with spinal shock in an spinal injured patient. The likely cause of these findings is not hypovolemia, but rather spinal shock.

Which of the following is the priority nursing diagnosis for the patient who has undergone surgery for a spinal fusion? 1. Acute Pain 2. Impaired Mobility 3. Risk for Infection 4. Risk for Injury

Correct Answer: 2 Rationale: The priority nursing diagnosis for a patient who has undergone a spinal fusion is Impaired Mobility, due to the assessment of the ABCs (airway, circulation, breathing). Impaired mobility can affect the patient's circulation, therefore affecting tissue perfusion and causing a risk for skin breakdown. Acute Pain is the next priority since it is an active diagnosis. Diagnoses with "risk for" do not take priority over active diagnoses.

The nurse understands that when the spinal cord is injured, ischemia results and edema occurs. How should the nurse explain to the patient the reason that the extent of injury cannot be determined for several days to a week? 1. "Tissue repair does not begin for 72 hours." 2. "The edema extends the level of injury for two cord segments above and below the affected level." 3. "Neurons need time to regenerate so stating the injury early is not predictive of how the patient progresses." 4. "Necrosis of gray and white matter does not occur until days after the injury."

Correct Answer: 2 Rationale: Within 24 hours necrosis of both gray and white matter begins if ischemia has been prolonged and the function of nerves passing through the injured area is lost. Because the edema extends above and below the area affected, the extent of injury cannot be determined until after the edema is controlled. Neurons do not regenerate, and the edema is the factor that limits the ability to predict extent of injury.

An industrial nurse is conducting a class to teach methods to prevent back pain. What is the correct of steps for lifting heavy objects? Choice 1. Spread the feet apart to broaden the base of support. Choice 2. Use large leg muscles to push when lifting. Choice 3. Stand as closely as possible to the object to be moved. Choice 4. Rolling or pushing the obect insrtead of lifting.

Correct Answer: 2,3,1,4 Rationale: In teaching prevention of back injuries the nurse would incorporate principles of proper body mechanics, which are work as close to the object as possible, spread feet apart, use large leg muscles for leverage. Sometimes rolling or pushing will enable movement of a heavy object.

A patient with a spinal cord injury (SCI) is admitted to the unit and placed in traction. Which of the following actions is the nurse responsible for when caring for this patient? Select all that apply. 1. modifying the traction weights as needed 2. assessing the patient's skin integrity 3. applying the traction upon admission 4. administering pain medication 5. providing passive range of motion

Correct Answer: 2,4,5 Rationale: The healthcare provider is responsible for initial applying of the traction device. The weights on the traction device must not be changed without the order of a healthcare provider. When caring for a patient in traction, the nurse is responsible for assessment and care of the skin due to the increased risk of skin breakdown. The patient in traction is likely to experience pain and the nurse is responsible for assessing this pain and administering the appropriate analgesic as ordered. Passive range of motion helps prevent contractures; this is often performed by a physical therapist or a nurse.

A patient has manifestations of autonomic dysreflexia. Which of these assessments would indicate a possible cause for this condition? Select all that apply. 1. hypertension 2. kinked catheter tubing 3. respiratory wheezes and stridor 4. diarrhea 5. fecal impaction

Correct Answer: 2,5 Rationale: Autonomic dysreflexia can be caused by kinked catheter tubing allowing the bladder to become full, triggering massive vasoconstriction below the injury site, producing the manifestations of this process. Acute symptoms of autonomic dysreflexia, including a sustained elevated blood pressure, may indicate fecal impaction. The other answers will not cause autonomic dysreflexia.

While caring for the patient with spinal cord injury (SCI), the nurse elevates the head of the bed, removes compression stockings, and continues to assess vital signs every two to three minutes while searching for the cause in order to prevent loss of consciousness or death. By practicing these interventions, the nurse is avoiding the most dangerous complication of autonomic dysreflexia, which is which of the following? 1. hypoxia 2. bradycardia 3. elevated blood pressure 4. tachycardia

Correct Answer: 3 Rationale: Autonomic dysreflexia is an emergency that requires immediate assessment and intervention to prevent complications of extremely high blood pressure. Additional nursing assistance will be needed and a colleague needs to reach the physician stat.

A school nurse is called after a student falls down a flight of stairs. The student is breathing, but unconsciousness. After calling the ambulance, which is the most appropriate action by the nurse? 1. Protect the patient's neck and head from any movement. 2. Place the patient on his side to prevent aspiration. 3. Immobilize the neck,,securing the head. 4. Try to rouse the patient by gently shaking his shoulders.

Correct Answer: 3 Rationale: Guidelines for emergency care are avoiding flexing, extending, or rotating the neck; immobilizing the neck; securing the head; maintaining the patient in the supine position; and transferring from the stretcher with backboard in place to the hospital bed. This patient is unconscious, and the nurse must protect the neck from any (or any further) damage. If the patient vomits, the nurse should utilize the log-roll technique to turn the patient while keeping the head, neck, and spine in alignment. Rousing the patient by shaking could cause damage to the spinal cord.

Which of the following is the priority nursing diagnosis for a patient diagnosed with a spinal cord injury? 1. Fluid Volume Deficit 2. Impaired Physical Mobility 3. Ineffective Airway Clearance 4. Altered Tissue Perfusion

Correct Answer: 3 Rationale: Ineffective Airway Clearance is the priority nursing diagnosis for this patient. The nurse utilizes the ABCs (airway, breathing, circulation) to determine priority. With Ineffective Airway Clearance, the patient is at risk for aspiration and therefore, impaired gas exchange. Fluid Volume Deficit is the nurse's next priority (circulation), and then Altered Tissue Perfusion. If the patient does not have enough volume to circulate, then tissue perfusion cannot be adequately addressed. The last priority for this patient is Impaired Physical Mobility.

The nurse realizes that the goal of surgery for a patient with a secondary metastatic spinal cord tumor is 1. complete removal of the tumor and affected spinal cord tissue. 2. eradication of the tumor with excision and drainage. 3. tumor excision to reduce cord compression. 4. exploration to visualize the tumor and obtain a biopsy.

Correct Answer: 3 Rationale: The tumor can exert pressure on the spinal cord, which interferes with function. In the case of secondary metastatic spinal tumor (which means a second site of cancer) and the metastasis (spread of cancer) the patient outcome may be limited to preventing compression on the spinal cord and not totally removing the cancerous lesion. Complete removal along with affected spinal tissue or eradication by excision and drainage would not be likely due to the secondary nature of the tumor and the resulting disability. Biopsy can be accomplished without direct visualization.

Of the following, which groups are the most at risk for bacterial meningitis? Select all that apply. 1. older adults 2. pregnant women 3. military recruits 4. college students 5. low-income

Correct Answer: 3,4 Rationale: Military personnel living on a base and young adults living in close proximity (such as college students living in a dormitory) are at a greater risk of contracting bacterial meningitis. The other populations are at lower risk.

Which of the following nursing actions is appropriate for preventing skin breakdown in a patient who has recently undergone a laminectomy? 1. Provide the patient with an air mattress. 2. Place pillows under patient to help patient turn. 3. Teach the patient to grasp the side rail to turn. 4. Use the log roll to turn the patient to the side.

Correct Answer: 4 Rationale: A patient who has undergone a laminectomy needs to be turned by log rolling to prevent pressure on the area of surgery. An air mattress will help prevent skin breakdown but the patient still needs to be turned frequently. Placing pillows under the patient can help take pressure off of one side but the patient still needs to change positions often. Teaching the patient to grasp the side rail will cause the spine to twist, which needs to be avoided.

A patient with a spinal cord injury (SCI) has complete paralysis of the upper extremities and complete paralysis of the lower part of the body. The nurse should use which medical term to adequately describe this in documentation? 1. hemiplegia 2. paresthesia 3. paraplegia 4. quadriplegia

Correct Answer: 4 Rationale: Quadriplegia describes complete paralysis of the upper extremities and complete paralysis of the lower part of the body. Hemiplegia describes paralysis on one side of the body. Paresthesia does not indicate paralysis. Paraplegia is paralysis of the lower body.

A hospitalized patient with a C7 cord injury begins to yell "I can't feel my legs anymore." Which is the most appropriate action by the nurse? 1. Remind the patient of her injury and try to comfort her. 2. Call the healthcare provider and get an order for radiologic evaluation. 3. Prepare the patient for surgery, as her condition is worsening. 4. Explain to the patient that this could be a common, temporary problem.

Correct Answer: 4 Rationale: Spinal shock is a condition almost half the people with acute spinal injury experience. It is characterized by a temporary loss of reflex function below level of injury, and includes the following symptomatology: flaccid paralysis of skeletal muscles, loss of sensation below the injury, and possibly bowel and bladder dysfunction and loss of ability to perspire below the injury level. In this case, the nurse should explain to the patient what is happening.
