30-60 minutes
What is the difference between a complete and incomplete SCI?
A complete SCI is one in which the spinal cord has been damaged in a way that eliminates all innervation BELOW the level of the injury. Injuries that allow some function or movement BELOW the level of the injury are described as an incomplete SCI. Incomplete injuries are more common than complete SCIs.
How is multiple sclerosis (MS) diagnosed?
Abnormal CSF findings= elevated protein level & slight increase in WBC count CSF electrophoresis= reveals an increase in the myelin basic protein and the presence of increased immunoglobulins **IgG bands are seen in most pts with MS MRI of the brain and spinal cord demonstrates the presence of plaques MRI w/o contrast shows active lesions and reveals older lesions Assessment of CN function, coordination, strength, reflexes, and sensations are needed to diagnose MS
Explain care for the patient following a surgical spinal fusion.

What should you as the nurse teach a pt about prevention of heat-related illnesses?
Avoid alcohol and caffeine Prevent overexposure to the sun; use a sunscreen with an SPF of at least 30 with UVA and UVB protection Rest frequently and take breaks from being in a hot environment Plan to limit activity at the hottest time fo day Wear clothing suited to the environment. Lightweight, light-colored, and loose-fitting clothing is best Pay attention to your personal physical limitations; modify activities accordingly Take cool baths or showers to help reduce body temperature Stay indoors in air-conditioned buildings if possible Ask a neighbor, friend, or family member to check on the older adult at least twice a day during a heat wave
What should you teach a patient being discharged with a halo fixator?
Be aware that the weight of the halo alters balance. Be careful leaning forward or backward. Wear loose clothing. Bathe in the bathtub or take a sponge bath. Wash under the liner of the vest to prevent rashes or sores; use powders or lotions sparingly under the vest. Have someone change the liner if it becomes odorous. Support the head with a small pillow when sleeping to prevent unnecessary pressure and discomfort. Try to resume usual activities to the extent possible; keep as active as possible (the weight may cause weakness or fatigue). BUT avoid contact sports and swimming. Do NOT drive because vision is impaired with the device. Keep straws available for drinking fluids. Cut meats and other foods into small pieces to facilitate chewing and swallowing. Before going outside in cold temperature, wrap the pins with cloth to prevent the metal from getting cold. Have someone clean the pin sites as recommended by PHCP or hospital protocol. Observe the pin sites daily for redness, drainage, or loosening; report changes to PHCP. Increase fluids and fiber in the diet to prevent constipation. Use a position of comfort during sexual activity.
What discharge teaching should the nurse provide for a patient after an anterior cervical diskectomy and fusion (ACDF)?
Be sure that someone stays with the pt for the first few days after surgery Review drug therapy Teach care of the incision Review activity restrictions: **NO LIFTING **NO DRIVING UNTIL SURGEON PERMISSION **NO STRENUOUS ACTIVITIES Walk every day Call surgeon if symptoms of pain, numbness, or tingling worsen or if swallowing becomes difficult Wear brace or collar per surgeon's prescription
Why are patients with cervical cord injuries at risk for orthostatic hypotension?
Because of interrupted sympathetic innervation caused by the SCI, the blood vessels do not constrict quickly enough to push blood up into the brain. The resulting vasodilation causes dizziness or light-headedness and possible falls with syncope ("blackout").
What is blunt trauma? List some examples.
Blunt trauma results from impact forces Ex: motor vehicle crash, a fall, an assault with fists, kicks, or a baseball bat
What are some contributing factors to low back pain in older adults?

How to prevent snakebites?
Do not keep venomous snakes as pets. Be extremely careful in locations where snakes may hide such as tall grass, rock piles, ledges and crevices, woodpiles, brush, boxes, and cabinets. Snakes are most active on warm nights. Don protective attire such as boots, heavy pants, and leather gloves. When walking or hiking, use a walking stick or trekking poles. Inspect suspicious areas before placing hands and feet in them. Do not harass snakes you may encounter. Striking distance can be up to two thirds the length of the snake. Even young snakes pose a threat; they are capable of envenomation from birth. Be aware that newly dead or decapitated snakes can inflict a bite for up to an hour after death because of persistence of the bite reflex. Do not transport the snake with the victim to the medical facility. Take a picture of the snack instead.

What should you teach the pt with MS?
Emphasize the importance of avoiding rigorous activities that increase body temperature. **Increased body temperature may lead to increased fatigue, diminished motor ability, and decreased visual acuity. Teach he pt and family to keep the home environment as structured and free from clutter as possible. Teach the pt the importance of planning activities and allowing sufficient time to complete activities. An eye patch that is alternated from eye to eye every few hours usually relieves diplopia (double vision). Provide written instructions as a resource for the patient and caregivers at home. Emphasize the importance of avoid overexertion, stress, extremes of temperature (fever, hot baths, use of sauna baths, and hot tubs, overheating, and excessive chilling), humidity, and people with infections.
What is the highest-priority intervention when managing a trauma patient?
Establishing a patient airway is the highest-priority intervention when managing a trauma unless massive, life-threatening external hemorrhage.
What exercises should you teach to a patient with chronic or postoperative back pain?
Extension Exercises: 1. Stomach lying- lie face down with a pillow under your chest; lift legs straight up (alternate legs) 2. Upper trunk extension: lie face down with your arms at your sides and life your head and neck 3. Prone push-ups: lie face down on a mat and, keeping your body stiff, push up to extend your arms Flexion Exercises: 1. Pelvic tilt- lying on your back with your knees bent, tighten your abdominal muscles to push your lower back against the mat 2. semi-sit ups- lying on your back with your knees bent, raise your upper body at a 45 degree angle and hold this position for 5-10 seconds 3. Knee to chest- lying on your back with your knees bent, tighten your abdominal muscles to push your lower back against the mat. Now bring one or both knees to your chest and hold this position for 5-10 seconds
What is flail chest?
Flail chest is the result of fractures of at least 2 neighboring ribs in 2 or more places causing PARADOXICAL CHEST WALL MOVEMENT (inward movement of the thorax during inspiration, outward movement during expiration) It usually involves one side of the chest and results from blunt chest trauma.
What should teach a pt with a SCI about aging?
Follow guidelines for adult vaccination, particularly the flu and pneumococcus vaccinations. **Respiratory complications are the most common cause of death after SCI! For women, have Pap smears and mammograms as recommended. Take measures to prevent osteoporosis, such as increasing calcium intake, avoiding caffeine, and not smoking. Exercise against resistance can maintain muscle strength and slow muscle loss. **Women older than 50 yo often lose bone density, which can result in fractures. Practice meticulous skin care, including frequent repositioning, using pressure-reduction surfaces in bed and chairs/wheelchairs, and applying skin protective products. **As the person ages, skin becomes dry and less elastic, predisposing the patient to pressure injuries. Take measures to prevent constipation, such as drinking adequate fluids, eating a high-fiber diet, adding a stool softener or bowel stimulant daily, and establishing a regular time for bowel elimination. **Constipation is a problem for most pts with SCI. Modify activités if joint pain occurs; use a powered rather than a manual wheelchair. **Arthritis occurs in more than half of people older than 65 years old. Patients with SCI are more likely to develop arthritis as a result of added stress on the upper extremities when using a wheelchair.

What are the 5 primary mechanisms of injury for a SCI?
Hyperflexion--a sudden and forceful acceleration of the head forward, causing extreme flexion of the neck; ex: head-on motor vehicle collision Hyperextension--the head is suddenly accelerated and then decelerated; ex: vehicle collision where the vehicle is struck from behind or during falls when the pt's chin is struck Axial loading or vertical compression--vertical compression; ex: diving accidents Excessive rotation--turning of the head beyond normal range Penetrating trauma--ex: GSW
What should you do if a SCI patient begins experiencing autonomic dysreflexia (AD)?
If the pt experiences AD, raise the HOB IMMEDIATELY to help reduce the BP. Notify HCP IMMEDIATELY for drug therapy to quickly reduce BP. Determine the cause of AD and treat it promptly. If bladder extended, catheterize pt. Check catheter for kinks or obstruction. Assess for UTI or bladder stones Check for fecal impaction or other colorectal irritation Examine skin for new or worsening pressure injury symptoms Monitor BP q 10-15 minutes!!! Give nifedipine or nitrate as prescribed to lower BP as needed Check room temperature and bed coverings and adjust pt for comfort ***PRIORITY= PLACING PT IN A SITTING POSITION
