to the periphery • Affects both genders • Etiology is unknown, but is believed to be a cell mediated immunologic reaction directed at the peripheral nerves • Often preceded by immune system stimulation from a viral infection, trauma, surgery, viral immunizations, HIV, or lymphoproliferative neoplasm’s • Campylobacter jejuni • Heterogeneous • Symptoms usually develop 1-3 weeks after an upper respiratory or GI infection • Weakness of the lower extremities occurs over hrs to days to weeks, usually peaking about the 14th day • Distal muscles are more severely affected • Numbness and tingling in the extremities • Reduced muscle tone and lack of reflexes are common and persistent symptoms • Pain, worse are night • Respiratory or UTIs may occur • immobility • diagnosis based on patients history and clinical signs • CSF is normal or has a low protein but after 7-10 days shows and elevated protein level to 700mg/dl • EMG and nerve conduction studies-show sever abnormalities • Supportive care • Ventilatory support during the acute phase • Plasma exchange used in the first two weeks IB of high dose Sandoglobulin-need to be well hydrated and have adequate renal function • After 3 weeks of disease onset, plasma exchange and immunoglobulin therapies have little value Nutritional Therapy: • Difficulty swallowing b/c of cranial nerve involvement-place patient in upright position and flexing the head forward during feedings • TPN • Monitor body weight, albumin, and calorie counts regularly • Support body symptoms until the patient recovers • Monitor ABGs • Suctioning • Urinary retention is common for a few days • Intermittent catheterization preferred to avoid UTIs • PT • Passive ROM • Artificial tears frequently during the day 24 • • • • • • Inspect eyes for presence of eyelashes Check for gag reflex Note drooling and other secretions which may be indicative of an inadequate gag reflex B/C of delayed gastric emptying, residual volumes of the feedings should be assessed at regular intervals or before feedings Monitor fluid and electrolyte balances Begin bowel program b/c constipation is a common problem Amyotrophic Lateral Sclerosis • • • • • • • • • • • Rare progressive neurologic disorder Loss of motor neurons Usually leads to death within 2-6 yrs after diagnosis Onset between 40-70 yrs old More common in men For unknown reasons motor neurons in the brainstem and spinal cord gradually degenerate Symptoms-weakness in the legs Death is from respiratory infection secondary to compromised respiratory function No cure Riluzole slows the progression • It decreases the amount of glutamate in the brain Support the patients cognitive and emotional functions by facilitating communication, reducing risk of aspiration, decreasing pain secondary to muscle weakness, decreasing risk of injury related to falls, providing divisional activities such as reading and human companionship, and helping the person and family with advance are planning and anticipatory grieving related to loss of motor function and death Seizure Disorders and Epilepsy Seizures • Paroxysmal, uncontrolled electrical discharge of neurons in the brain that interrupts normal function • Often symptoms of underlying diseases • May occur spontaneously without any apparent cause Epilepsy • Person has spontaneously recurring seizures caused by a chronic underlying condition • Higher in underdeveloped countries • Rates are higher during the first year of life, decline during childhood and adolescence, plateau in middle age, and rise sharply again among the elderly Etiology and Pathophysiology • Most common cause during first 6 months of life are severe birth injury, congenital defects involving the CNS, infections, and inborn errors of metabolism 25 • Clinical Manifestations Generalized Seizures Partial Seizures Pt’s between 2-20yrs old the primary causative factors are birth injury, infection, trauma, and genetic factors • Between 20-30yrs old usually occurs as the result of structural lesions, such as trauma, brian tumors, or vascular disease • After 50 the cause are cerebrovascular lesions and metastatic brain tumors • ¾ of all seizure disorder cases can’t be attributed to a specific cause and are considered idiopathic • Preferred method of classifying recurring seizures is the International Classification System • Seizures are divided into Generalized and Partial Seizures • Phases: • Prodromal-with signs or activity which precede a seizure • Aural-Sensory warning • Ictal-full seizure • Postictal-period of recovery after the seizure • Characterized by bilateral synchronous epileptic discharges in the brain from the onset of the seizure • No warning or aura • Pt loses consciousness for a few seconds to several minutes Tonic Clonic Seizures • Most common generalized seizure • Loss of consciousness and falling to the ground • Followed by stiffening of the body for 10-20 seconds and subsequent jerking of the extremitites for another 30-40 seconds • Cyanosis, excessive salivation, tongue or cheek biting and incontinence may accompany the seizure • In postictal phase the pt usually has muscle soreness, is very tired, and may sleep for several hrs • Pt has no memory of the seizure Typical Absence Seizures • Usually occurs only in kids • May cease as kid grows older • Brief staring spell that lasts only a few seconds • Often unnoticed • When untreated, may occur up to 100 times a day • Can often be precipitated by hyperventilation and flashing lights Atypical Absence Seizures • Staring spell accompanied by other signs and symptoms, including brief warnings, peculiar behaviour during the seizure, or confusion after the seizre • Being in specific region of the cortex • May be confined to one side of the brain and may spread to other parts of the brain 26 • • Complications Diagnostic Studies Collaborative Care Nursing Management Todd’s paralysis (focal weakness) Involves lip smacking and automatisms (repetitive movements that may not be appropriate)-picking at clothing, fumbling with objects, or walking away Physical • Status Epilepticus • State of continuous seizure activity or a condition in which seizures recur in rapid succession without return to consciousness between seizures • Most serious complication of epilepsy and is a neurologic emergency • Neurons become exhausted and cease to function • Permanent brain damage may result • Death from head injury • Drowning in the bathtub Psychosocial • Associated with supernatural powers • Possession by the devil • Insanity • May experience employment discrimination • Driving laws • Birth and development history • Significant illnesses and injuries • Family History • Febrile seizures • Comprehensive neurologic assessment • Precipiating factors • Antecendent events • Seizure description • CBC, UA, LYTES, CREA, fasting blood glucose • Lumbar puncture • CT, MRI, MRA, MRS, PET scans • EEG • Antiseizure drugs • Surgery • Vagal nerve stimulation • Psychosocial counseling • Wear helmets • Maintain proper diet • Adequate rest 27 • • • • • Exercise When seizure occurs observe and record all details of the event-onset, course and nature of the seizure (LOC, tongue bitting, automatisms, stiffening, jerking, total lack of muscle tone), body parts involved, presence of autonomic signs, such as dilated pupils, excessive salivation, altered breathing, cyanosis, flushing, diaphoresis, incontinence During the seizure maintain airway-supporting the head, turning the pt to the side, loosening constrictive clothing, easing the pt to the floor Don’t restrain the pt DON”T PLACE THINGS IN THE MOUTH Mastectomy • Removal of breast and auxiliary lymph nodes, • Preserves the pectorals major muscle. • Selected if the tumor is too large to excise with good margins and attain a reasonable cosmetic result. • Reconstructive surgery can be performed immediately following the mastectomy or delayed until post op recovery (6 months) • The most common site of recurrence of breast cancer is at the surgical site Follow Up Care • The woman must be followed up for the rest of her life at regular intervals. • Examinations every 6months for 2 years then annually thereafter. • Most continue BSE monthly on both breast or remaining breast and mastectomy site. • Most common site of recurrence is surgical site. Post Mastectomy Pain Syndrome • S/S- chest and upper arm pain, tingling down the arm, numbness, shooting/pricking pain, and unbearable itching that persist beyond the normal 3 month healing time. • Rx- NSAIDS, antidepressants, topical lidocaine patches, guided imagery training, physical therapy to prevent “frozen shoulder” syndrome R/t dec. movement, and psychologic counseling. Prostate Cancer Pathophysiology • • • • • • • • Androgen-dependent adenocarcinoma The majority of tumors occur in the outer aspect of the prostate gland Usually slow growing Spreads by three routes: direct extension, lymph system, bloodstream Spread by direct extension involves the seminal vesicles, urethral mucosa, bladder wall, and external sphincter The cancer later spreads through the lymphatic system to the regional lymph nodes The veins from the prostate seem to be the mode of spread to the pelvic bones, head of the femur, lower lumbar spine, and lungs Age, ethnicity, and family history are 3 nonmodifiable risk factors 28 Clinical Manifestations Collaborative Care Health Promotion • • • • • • • The incidence of prostate cancer rises markedly after age 50 AA have the highest incidence of prostate cancer of any ethnic group A high-fat diet is thought to be associated with an increased risk of prostate cancer Occupational exposure to chemicals may be associated with higher prostate cancer risk A history of BPH is not a risk factor Usually asymptomatic in the early stages Eventually, the patient may experience dysuria, hesitancy, dribbling, frequency, urgency, hematuria, nocturia, retention, interruption of urinary system, and inability to urinate • Pain in the lumbosacral area that radiates down to the hips or legs, when coupled with urinary symptoms, may indicate metastasis • The tumor can spread to pelvic lymph nodes, bones, bladder, lungs, and liver. • Once the tumor has spread to distant sites, the major problem becomes the management of pain • As the cancer spreads to the bones, pain becomes severe, especially in the back and legs because of compression of the spinal cord and destruction of bone • Early-stage prostate cancer is a curable disease in the majority of men • Collaborative care depends on the stage of cancer and overall health of patient Stage A (clinically unrecognized) • Watchful waiting with annual PSA and DRE • Radical prostatectomy • Radiation therapy (external beam, brachytherapy) Stage B (clinically intracapsular) • Radical prostatectomy • Radiation therapy Stage C (clinically extracapsular, localized to periprostatic area) • Radical prostatectomy • Radiation therapy • Hormone therapy • Orchiectomy Stage D (metastatic disease) • Hormone therapy • Orchiectomy • Chemotherapy • Radiation therapy to metastatic bone areas Prognosis is very unfavorable • Encourage patients to have annual prostate screening (PSA and DRE) starting at age 50 or younger if risk factors are present • Acute Intervention Ambulatory/Home Care • • • • • • • 29 AA men and other men with family history of prostate cancer should have annual PSA and DRE beginning at age 45 Provide sensitive, caring support for patient and family to help cope with diagnosis of cancer Preoperative and postoperative phases of radical prostatectomy are similar to procedures for BPH If patient is discharged with an indwelling catheter in place, the patient must be taught appropriate catheter care Instruct patient to clean urethral meatus with soap and water once a day, maintain high fluid intake, keep collecting bag lower than bladder at all times, keep catheter securely anchored to inner thigh or abdomen, and report any signs of bladder infections such as bladder spasms, fever, or hematuria If urinary incontinence is a problem, patients should be encourage to practice pelvic floor muscle exercises (Kegel exercises) at every urination and throughout day Continuous practice during the 4 to 6 week healing process improves success rate Management of pain is one of the most important aspects of nursing care for patients with stage D prostate cancer BPH • BPH is an enlargement of the prostate gland resulting from an increase in the number of epithelia cells and stromal tissue. • It is the most common problem of the adult male reproductive system. • Prostate hyperplasia does not predispose to the development of prostate cancer. • BPH develops in the inner part of the prostate. • This enlargement gradually compresses the urethra, eventually leading to partial or complete obstruction. • It is the compression of the urethra that ultimately leads to the development of clinical symptoms. • There is no direct relationship between the size of the prostate and degree of obstruction. • It is the location of the enlargement that is most significant in the development of obstructive symptoms. Risk factors • Family history • Environment • Diet • Higher risk for BPH has been found in association with a diet high in zinc, butter, and margarine. Health Promotion • The cause of BPH is largely attributed to the aging process; the focus of health promotion is on early detection and treatment • A yearly medical history and DRE for men over 50 yrs of age is recommended to provide early detection of prostate problems • Ingestion of alcohol and caffeine tends to increase prostatic symptoms because the diuretic effect of these substances increases bladder distention • Compounds found in common cough and cold remedies such as pseudoephedrine and phenylephrine often worsen the symptoms of BPH Acute Intervention 30 • The patient with obstructive symptoms should be advised to urinate every 2 to 3 hours and when first feeling the urge to minimize urinary stasis and acute urinary retention • Fluid intake should be maintained at a normal level to avoid dehydration or fluid overload; restricting fluid intake increases the chances of infection • If the patient increases fluid intake too rapidly, bladder distention can develop because of prostatic obstruction Preoperative • Urinary drainage must be restored before surgery; a urethral catheter such as a Coude (curvedtip) catheter may be needed to restore drainage • Antibiotics are usually administered before any invasive procedure; any infection of the urinary tract must be treated before surgery • Restoring urine drainage and encouraging a high fluid intake (2 to 3 L/day) are also helpful in managing infection • The patient needs to know how the surgery may affect sexual functioning • Inform patient that the ejaculate may be decreased in amount or totally absent • Retrograde ejaculation results in some degree Postoperative • The main complications following surgery are hemorrhage, bladder spasms, urinary incontinence, and infection • Patient will have standard catheter or a triple lumen catheter • Bladder irrigation is done to remove clotted blood from bladder and ensure drainage of urine • If the bladder is manually irrigated, 50 mL of irrigating solution should be instilled and then withdrawn with a syringe to remove clots that may be in the bladder and catheter • With continuous bladder irrigation (CBI), irrigating solution is continuously infused and drained from the bladder; the rate of infusion is based on the color of drainage • Ideally the urine drainage should be light pink without clots • The secretions that accumulate around the meatus can be cleansed daily with soap and water • Blood clots are expected for the first 24 to 36 hrs after surgery • Postoperative hemorrhage may occur from displacement of the catheter, dislodging a large clot, or increases in abdominal pressure • Traction on catheter may be applied to provide counterpressure (tamponade) on bleeding site in prostate, thereby decreasing bleeding • Instruct patient not to urinate around catheter because this increases the likelihood of spasm • If bladder spasms develop, check catheter for clots • The catheter is often removed 2 to 4 days after surgery • The patient should urinate within 6 hrs after catheter removal • Sphincter tone can be strengthened by Kegel exercises 10 to 20 times per hour while awake Ambulatory/Home Care 31 • Patient should be encouraged to practice starting and stopping the stream several times during urination to facilitate learning the pelvic floor exercises • In some instances, control of urine may never be fully regained • The patient can also be instructed to use a penile clamp, condom catheter, or incontinence pads or briefs to avoid embarrassment from dribbling Dietary intervention and stool softeners are important to prevent patient from straining while having bowel movements • Instructions include: 1. caring for indwelling catheter if one is left in place 2. managing urinary incontinence 3. maintaining oral fluids between 2 to 3 L/day\ 4. observing for S/S of UTI and wound infection 5. preventing constipation 6. avoiding heavy lifting (more than 10 lb) 7. refraining from driving or intercourse after surgery as directed by physician • Many men experience retrograde ejaculation because of trauma to internal sphincter; semen is discharged into bladder at orgasm and may produce cloudy urine when patient urinates after orgasm • Although some patients experience concerns regarding change in sexual function, this is not a universal concern; many men are comfortable with such changes and view them as appropriate for their age • The bladder may take up to 2 months to return to normal capacity • Instruct patient to drink at least 2 L of fluid/day and urinate every 2 to 3 hrs to flush urinary tract Advise patient to continue to have a yearly DRE if he has had any procedure other than complete removal of the prostate TREATMENT Transurethral resection of the prostate (TURP) DESCRIPTION - - Open prostatectomy - Use of excision and cauterization to remove prostate tissue cytoscopically Considered the most effective treatment of BPH Surgery of choice for men with large prostates ADVANTAGES - - DISADVANTAGES Best long-term relief of prostatic obstruction Erectile dysfunction unlikely - Bleeding Retrograde ejaculation Complete visualization of prostate and surrounding tissue - ED Bleeding Postoperative pain 32 - Transurethral incision of the prostate (TUIP) Transurethral microwave thermotherapy (TUMT) Transurethral needle ablation of the prostate (TUNA) Involves external incision with three possible approaches (retropubic, perineal, suprapubic) - Involves making transurethral slits or incisions into prostatic tissue to relieve obstruction - Effective for men with relatively little prostatic involvement Use of microwave radiating heat to produce coagulative necrosis of the prostate - Usually only indicated if prostate gland is very large - Risk of infection - Outpatient procedure Minimal complications Good for high risk patients No ED or retrograde ejaculation - Considered temporary solution to obstructive problem Urinary catheter needed after procedure - Low-wave radiofrequency used to heat the prostate causing necrosis - Outpatient procedure Short procedure ED and retrograde ejaculation are rare Short outpatient procedure ED and retrograde ejaculation are rare Precise delivery of heat to desired area Very little pain experienced by patient Short procedure Minimal bleeding Fast recovery time Very effective - - - Laser Prostatectomy Transurethral electrovaporization of prostate (TUVP) Urethral Stents - Procedure uses a laser beam to cut or destroy part of the prostate - Different techniques available: visual laser ablation of prostate, contact laser technique, interstitial laser coagulation Electrosurgical vaporization and desiccation are used together to destroy prostatic tissue Insertion of self-expandable metallic stent into urethra where enlarged area of prostate occurs - - Minimal risks Minimal bleeding and sloughing Safe and effective Low risk - - - Potential for damage to surrounding tissue Urinary catheter needed after procedure Urinary retention common Irritative voiding symptoms Hematuria - Postprocedure catheterization (up to 7 days) needed because of edema and urinary retention Delayed sloughing of tissue Takes several weeks to reach optimal effect Retrograde ejaculation - Retrograde ejaculation Intermittent hematuria - Stent may move Long-term experience is limited - 33 • • PNEUMONIA Acute inflammation of the lung parenchyma caused by a microbial agent Leading cause of death from an infectious disease in the U.S Etiology • Normal Defense Mechanisms • Factors Predisposing to Pneumonia ◊ Defense mechanisms become incompetent or are overwhelmed or overwhelmed by the virulence or quantity of infections agents ◊ Decreased consciousness depresses the cough, which may allow aspiration of Oropharyngeal contents into the lungs ◊ Tracheal intubation ◊ air pollution, cigarette smoking, viral upper respiratory infections, and normal Changes of aging ◊ Malnutrition ◊ Bed rest and prolonged immobility ◊ Chronic diseases • Acquistion of Organisms 1. Aspiration from the nasopharynx or oropharynx 2. Inhalation of microbes present in the air 3. Hematogenous spread from a primary infection elsewhere in the body Pathophysiology • Pneumococcal pneumonia is the most common cause of bacterial pneumonia • 4 characteristic stages of the disease process: 1. Congestion: outpouring of fluid into the alveoli→ organisms multiply in the serous fluid, and the infection is spread 2. Red hepatization: massive dilation of the capillaries, and alveoli are filled w/organisms, neutrophils, RBCs and fibrin 3. Gray hepatization: blood flow decreases, and leukocyte and fibrin consolidate in the affected part of the lung 4.

Clear w/effective coughing and deep breathing • Delayed resolution from persistent infection and is seen on x-ray as residual consolidation. 34 • • • Diagnostic Studies • • • • • • • Collaborative Care • • • • • • • • • • • Lung abscess Empyema: accumulation of purulent exudates in the pleural cavity. Requires antibiotic therapy and drainage of the exudates by a chest tube or open surgical drainage Pericarditis: from spread of the infecting organism from an infected pleura or via hematogenous route to the pericardium Arthritis: from systemic spread of the organism. Meningitis Endocarditis: organism attack the endocardium and the valves of the heart History and physical examination Chest x-ray: shows a typical pattern characteristic of the infecting organism and is an invaluable adjunct in the diagnosis of pneumonia. Gram stain of sputum: provides info on the predominant causative organism. Sputum culture and sensitivity test: if drug resistant pathogen or organism not covered by empiric therapy Pulse Oximetry or ABGs CBC, differential, and routine blood chemistries Blood cultures Prompt Rx w/ the appropriate antibiotic almost always cures bacterial and mycoplasma pneumonia Oxygen therapy for hypoxemia Analgesics to relieve chest pain Antipyretics for significantly elevated temp During acute febrile phase, pt’s activity should be restricted, and rest should be encouraged and planned Influenza vaccine is considered a mainstay of prevention and is recommended annually for use in the individual considered to be at risk Pneumococcal Vaccine 1.

Doxycycline (Vibramycin) recommended for pt who is allergic to marolides, but is not reliably active against pneumococcus organisms 35 • Nursing Management • • Types of Pneumonia • • ◊ Clinical response evaluated by factors such as change in fever, sputum purulence, leukocytosis, oxygenation or x-ray patterns Nutritional Therapy ◊ fluid intake of at least 3 L per day ◊ At least 1500 cals per day to provide energy for the increased metabolic processes ◊ Small, frequent meals are better tolerated Health Promotion ◊ practice good health habits, such as proper diet and hygiene, adequate rest, and regular exercise ◊ avoid exposure to URI ◊ Pts w/altered consciousness place them in positions (side-lying, upright) that will prevent or minimize the risk of aspiration ◊ turn and reposition pt q2h ◊ Avoid overmedication w/narcotics or sedatives, which can cause a depressed cough reflex and accumulation of fluid in lungs ◊ Practice strict medical asepsis and adherence to infection control Ambulatory and Home Care ◊ reassure that complete recovery is possible ◊ Emphasize the need to take all of the prescribed drug and to return for follow up ◊ Drug-drug and the food-drug interactions should be taught ◊ Deep breathing exercises should be practiced for 6-8wks Community-Acquired Pneumonia (CAP) ◊ lower respiratory tract infection of the lung parenchyma w/onset in the community or

Involves lungs, but also larynx, kidneys, bones, adrenal glands, lymph nodes, and meninges Kills more pple worldwide than any other infectious disease Seen disproportionately in poor, underserved and minorities • Homeless pple, residents of inner city neighborhoods, foreign born persons, older adults, institutions, injection drug users, socioeconomically disadvantaged, and medically underserved of all races are at risk Etiology and Patho • Usually spread from person to person via airborne droplets • Repeated, close, prolonged exposure to infected person • Can’t be spread by fomites • When bacilli inhaled→ pass down bronchial system and implant on respiratory bronchioles or alveoli→ multiply w/no initial resistance from host→ spred through lymphatic channels to regional lymph node and via thoracic duct to circulating blood while cellular immune response is being activated • Lower lungs initial site of bacterial implantation • Table 27-7 Clinical Manifestations • Usually free of symptoms in early stages • Systemic: fatigue, malaise, anorexia, weight loss, low grade fever, night sweats 37 • Complications Diagnostic Studies Collaborative Care Pulmonary manifestation: cough that becomes frequent and produces mucoid or mucopurulent sputum, chest pain • Chills, flulike symptoms, pleuritic pain, and productive cough • Military TB ◊ blood invasion and spread to all body organs Pleural Effusion and Empyema ◊ fluid accumulation in pleural area ◊ Pus in the lungs Tuberculosis Pneumonia ◊ tubercle bacilli discharged from the liquefied necrotic lesion into the lung or lymph nodes • Other organ involvement • Tuberculin Skin testing ◊ positive reaction occurs 2-12 wks after the initial infection, corresponding to time needed to mount an immune response ◊ PPD used primarily to detect the delayed hypersensitivity response ◊ positive reaction indicates the presence of tuberculosis infection, BUT does not show whether the infection is dormant or active • Chest x-ray ◊ Important, but it’s not possible to make a diagnosis of TB solely on the basis of this ◊ This is b/c other diseases can mimic the x-ray appearance of TB • Bacteriologic Studies ◊ essential for establishing a dx ◊ usually the 1st bacteriologic evidence of the presence of tubercle bacilli ◊ 3 consecutive sputum specimens collected on diff days are obtained and sent for smear and culture ◊ most accurate means of dx is a culture technique ◊ Disadvantage: may take 6-8wks for mycobacterium to grow ◊ Nucleic acid amplification (NAA): rapid diagnostic test.

A fall in BP sensed by baroreceptors causes an activation of SNS. • Vascular endothelium is a single layer that lines the blood vessels. Endothelin which is prodeuced by endothelial cells is a potent vasoconstrictor. • Renal system. The kidneys contribute to BP regulation by controlling sodium excretion and ECF volume. Na retention- Water Retention- inc ECF voume - Inc venous return to the heart- Inc SV- Inc BP- Inc CO. The renin-angiotensin system plays an imp role as well. •Endocrine system.Stimulation of the SNS results in release of Epinephrine along with the norepinephrine by adrenal medulla. An inc in blood sodium stimulates the release of ADH. ADH increase the ECF volume, elevates BP.
