The Rancho Los Amigos Level of Cognitive Function is a scale frequently used to assess cognitive function and evaluate ongoing recovery from head injury order 50 mg penegra visa. Progress through the levels of cognitive function can vary widely for individual patients quality 100mg penegra. To allow the patient longer times of uninterrupted sleep and rest, the nurse can group nursing care activities so that the patient is disturbed less frequently. Back rubs and other measures to increase comfort can assist in promoting sleep and rest. Supporting Family Coping Having a loved one sustain a serious head injury can produce a great deal of prolonged stress in the family. Such changes are associated with disruption in family cohesion, loss of leisure pursuits, and loss of work capacity, as well as social isolation of the caretaker. The family may experience marital disruptions, anger, grief, guilt, and denial in recurring cycles (Hsueh-Fen & Stuifbergen, 2004). To promote effective coping, the nurse can ask the family how the patient is different now, what has been lost, and what is most difficult about coping with this situation. Helpful interventions include providing family members with accurate and honest information and encouraging them to continue to set well-defined short-term goals. Support groups help the family members share problems, develop insight, gain information, network, and gain assistance in maintaining realistic expectations and hope. The Brain Injury Association (see Resources) serves as a clearinghouse for information and resources for patients with head injuries and their families, including specific information on coma, rehabilitation, behavioral consequences of head injury, and family issues. This organization can provide names of facilities and professionals who work with patients with head injuries and can assist families in organizing local support groups. Many patients with severe head injury die of their injuries, and many of those who survive experience long-term disabilities that prevent them from resuming their previous roles and functions. During the most acute phase of injury, family members need support and facts from the health care team. Many patients with severe head injuries that result in brain death are young and otherwise healthy and are therefore considered for organ donation. Family members of patients with such injuries need support during this extremely stressful time and assistance in making decisions to end life support and permit donation of organs. Bereavement counselors and members of the organ procurement team are often very helpful to family members in making decisions about organ donation and in helping them cope with stress. Any decrease in this pressure can impair cerebral perfusion and cause brain hypoxia and ischemia, leading to permanent damage. Impaired Oxygenation and Ventilation Impaired oxygen and ventilation may require mechanical ventilatory support. The patient must be monitored for a patent airway, altered breathing patterns, and hypoxemia and pneumonia. Interventions may include endotracheal intubation, mechanical ventilation, and positive end-expiratory pressure. Impaired Fluid, Electrolyte, and Nutritional Balance Fluid, electrolyte, and nutritional imbalances are common in the patient with a head injury. Undernutrition is also a common problem in response to the increased metabolic needs associated with severe head injury. If the patient cannot eat, enteral feedings or parenteral nutrition may be initiated within 48 hours after the injury to provide adequate calories and nutrients (Bader et al. Nutritional support in the form of early feeding after head injury is associated with better survival outcomes and decreased disability (Yanagawa, Bunn, Roberts, et al. Post-traumatic Seizures Patients with head injury are at an increased risk for post-traumatic seizures. Post- traumatic seizures are classified as immediate (within 24 hours after injury), early (within 1 to 7 days after injury), or late (more than 7 days after injury) (Somjen, 2004). Seizure prophylaxis is the practice of administering antiseizure medications to patients with head injury to prevent seizures. However, many antiseizure medications impair cognitive performance and can prolong the duration of rehabilitation. Therefore, it is important to weigh the overall benefit of these medications against their side effects. Research evidence supports the use of prophylactic antiseizure agents to prevent immediate and early seizures after head injury, but not for prevention of late seizures (Somjen, 2004). The nurse must assess the patient carefully for the development of post-traumatic seizures. Risk factors that increase the likelihood of seizures are brain contusion with subdural hematoma, skull fracture, loss of consciousness or amnesia of 1 day or more, and age older than 65 years (Somjen, 2004). The nurse explains to the patient and family, verbally and in writing, how to monitor for complications that merit contacting the neurosurgeon.

When your energy comes back to you buy 50 mg penegra visa, it is tempting to overwork: to clean the whole house or to get into some gardening purchase 100mg penegra amex. Our test showed her body was full of bismuth (fragrance) and silver (tooth fillings) especially in the ovaries. She cleansed her kidneys and killed parasites but could not make up her mind to do the expensive dental work. Her skin, kidneys, breasts, brain, ovaries and pancreas were all loaded with mercury, platinum and other metals. Before the moving date arrived she had cleansed kidneys, killed parasites and done dental work and was feeling noticeably better. She immediately was very fatigued again and worried that the move had been in vain. This time she had a liver full of Salmonella and a return of phosphate crystals in her kidneys. But it was easy to clear up and it was a very useful lesson to her to avoid unsterilized dairy products. Her tissues were full of arsenic from pesticide; her urinalysis showed kidney crystals and her eosinophil count was high 5. She had sheep liver flukes and stages in her pancreas due to a buildup of wood alcohol there. In four months after killing parasites and doing a kidney cleanse she was much improved. She had Ascaris and pancreatic flukes in her pancreas and reacted to sugar in her diet quite strongly, so avoided it. In 6 weeks she had done everything except the mercury removal and was feeling much better. She cleaned her home and cleansed kidneys, killed parasites, and did two liver cleanses. Meanwhile, though, her infertility problem got solved (she got pregnant) and this encouraged her to continue the battle against fatigue after the baby was born. Hector Garcia, age 14, was getting gamma globulin injections every three weeks for his chronic fatigue syndrome. He had pancreatic flukes in his pancreas, sheep and human liver flukes in his liver and intestinal fluke in his intestine. He had a buildup of benzene, propanol, and carbon tetrachloride as well as aflatoxin from his granola breakfasts. He killed parasites with a frequency generator and went off the solvent polluted items in the propyl alcohol and ben- zene lists. Dana Levi, age 16, had chronic fatigue syndrome and dizziness; he was not in school. He had pancreatic fluke in his pancreas, sheep, human and intestinal flukes in his liver! As soon as the para- sites were killed (with a frequency generator) and he changed a lot of his products, he felt better but soon lost his improvement. At the next visit, our tests showed a buildup of vanadium (from burning candles in his bedroom). But getting a taste of normal energy gave him the determination to get himself well! His lungs and trachea had accumulated seven heavy metals: va- nadium, palladium, cerium, barium, tin, europium, beryllium. The gas leak was fixed (vanadium), the garage was sealed off from the house to eliminate barium and beryllium but the other toxic elements came from his dental retainer. As soon as his retainer came out, and they stopped using flea powder on their dog, his energy became normal and sinuses cleared up. Evelina Rojas, age 12, was having extreme fatigue with mood problems and sudden fevers. She killed Ascaris and sheep liver flukes with the parasite program but promptly got them back due to a benzene buildup I believe due to using products containing an herbal oil. Her high levels of Streptococcus pneumoniae (cause of fevers), Staphylococcus aureus and Nocardia could not be eliminated until her three baby teeth (with root canals) were pulled. She was toxic with arsenic, a substance that replaces en- ergy with nervous excitement and exhaustion. She also had a backlog of antimony (using baby oil), aluminum, rhenium (hair spray), benzalkonium (toothpaste) and radon. In four months, she had the arsenic and three other toxins eliminated and already had more energy. He had the mirac- idia of the intestinal fluke, sheep liver fluke, and pancreatic fluke in his thyroid! He had been drinking a great deal of regular tea, which let oxalate crystals deposit in his kidney and slow down the excretion of toxins. The parasites were killed with a frequency generator, he changed his diet to get rid of solvents. Change all detergents (for dishes, laundry, and body use) to borax and/or washing soda.
