Chapter 29 - Additional General Medical Conditions Flashcards
antigen
invading agent
active immunity
result of natural infection or invasion of antigents
passive immunity
inoculation
cell-mediated response
lymphocytes (T cells) are produced by the thymus in response to antigen exposure
humoral immune response
plasma lymphocytes (B Cells) are produced with subsequent formation of antibodies
non-specific immune response/inflammation
reaction of the tissues to injury from trauma, chemicals, or ischemia
auto-immune response
directed against an individual’s own tissues (diabetes mellitus, rheumatoid arthritis)
Viral Infections
rhinovirus, influenza, mono, rubella, rubeola, mumps, varicella
rhinovirus
common cold
rhinovirus etiology
transmitted by direct or indirect contact; spread by droplets expelled by sneezing, coughing, or speaking
rhinovirus s/sx
starts with a scratchy or sore throat, watery discharge/stopped-up nose, and sneezing
secondary infection is possible
rhinovirus management
symptomatic treatment (most last 5-10 days regardless of type of treatment)
avoidance
pleconaril - shortens duration of cold
influenza etiology
caused by myxoviruses (types *A, B, C, D); virus enters cell through genetic material, multiplies and is spread throughout the body (athletes in winter sports, basketball, wrestling, and swimming should get vaccinated)
Influenza s/sx
fever, cough, headache, malaise, and inflamed respiratory mucous membranes with coryza (profuse nasal discharge)
incubation period of 48 hours, chills, fever (102-103), aches, photophobia, acute phase lasts 5 days

steam, cough meds, salt water gargles
amantadine & Relenza
may be used for influenza A for individuals at risk
infectious mononucleosis etiology
caused by the Epstein-Barr virus (EBV); incubation is 4-6 weeks; EBV is carried in the throat and transmitted to another person through saliva (bad for athletes - severe fatigue and possible splenic rupture)
Mono s/sx
3-5 day prodrome of headache, fatigue, loss of appetite, and myalgia
day 5-15: fever, swollen glands, sore throat
second week: enlarged spleen, jaundice (10-15%), skin rash (5-15%), flushed cheeks, puffy eyelids
blood test: elevated WBC count
complications: ruptured spleen, meningitis, encephalitis, hepatitis, anemia
mono management
acetaminophen for headache, fever, malaise
can return to life 3 weeks after onset if spleen is not enlarged, no fever, liver is working normal, and pharyngitis has resolved
Rubella
German measles
Rubella etiology
highly contagious childhood viral disease; infection 13-24 days following exposure
Rubella s/sx
slight fever, sore throat, drowsiness, swollen lymph glands, appearance of red spots on the palate (occur 1-5 days prior to appearance of rash that occurs 50% of the time - rash begins on face/forehead and spreads down trunk and extremities, lasting for about 3 days)
Rubeola
measles
Rubeola etiology
highly contagious childhood viral disease (after having disease, individual has acquired immunity)
Rubeola s/sx
onset causes sneezing, nasal congestion, coughing, malaise, photophobia, spots in the mouth, conjunctivitis, fever that may elevate to 104 at about 4 days
onset of high fever, rash appears, lasts about 5 days, may cause itching
Rubeola management
every child should receive the MMR vaccine; bed rest, isolation in dark room, and antipyretic and anti-itching medication to provide relief while disease runs its course
Mumps (Parotitis) etiology
contagious viral disease that results in inflammation of the parotid and other salivary glands
appears 12-25 days following exposure
Mumps (Parotitis) s/sx
malaise, headache, chills, and a moderate fever. Pain in the neck below and in front of the ear
that progresses to marked swelling on one or both sides (may last for as long as 7 days); painful to move jaw and
swallowing may be difficult. Saliva production may be increased or decreased.
mumps (Parotitis) management
immunization with MMR. Patient should be isolated while contagious, confined to bed rest and
given a soft diet; analgesics may be used with cold applications to control swelling (later heat can be used)
Varicella (Chicken Pox)
chicken pox
varicella etiology
highly contagious viral disease caused by varicella-zoster virus. Also causes herpes zoster. Most likely to occur in children under 15 years of age; average incubation is 13-17 days following exposure. Individual is contagious for approximately 11 days (beginning 5 days before the first signs of rash appear)
varicella s/sx
begins with slight elevation of temperature for 24 hours, followed by eruption of rash
rash appears crop of red spots, begins on back/chest, disease lasts 2-3 weeks
varicella management
administration of varicella-zoster immune globulin (VZIg) within 96 hours of exposure will prevent clinical symptoms in normal healthy children. Acyclovir should be administered to adolescents and adults within 24-hours following appearance of symptoms.
Sinusitis etiology
can stem from a URI caused by a variety of bacteria, nasal mucous membrane walls and block the osmium of the paranasal sinus
sinusitis s/sx
sinus area may swollen and painful to touch; headache, malaise, purulent nasal discharge
sinusitis management
antibiotics, steam inhalation & other nasal topical sprays can produce vasoconstriction & drainage
pharyngitis
sore throat
pharyngitis etiology
acute inflammation of the pharyngitis (may be related to common cold, influenza, or mono)
Pharyngitis s/sx
pain on swallowing, fever, inflamed and swollen lymph glands, swollen tonsils, weakness, and anorexia
mucous membranes of throat may be inflamed with a covering of purulent matter
throat culture to rule out strep throat is necessary
pharyngitis management
topical gargles and rest, antibiotic therapy,
tonsillitis etiology
Tonsils are pieces of lymphatic tissue covered by epithelium; within each tonsil are deep clefts/pits
lined by lymphatic nodules (pathogens collect in pits and penetrate epithelium, where they contact lymphocytes and cause an acute inflammation and bacterial infection)
tonsillitis s/sx
tonsils appear inflamed, red, and swollen with a yellowish exudate in the pits; difficulty swallowing and possibly high fever with chills. Headache, pain in neck and back may also be present
tonsillitis management
throat culture, gargling with warm saline water, liquid diet, antipyretic medication
seasonal atopic (allergic) rhinitis
hay fever
seasonal atopic (allergic) rhinitis etiology
an acute seasonal allergic condition that results from airborne pollens
seasonal atopic (allergic) rhinitis s/sx
early stages: itchy eyes, throat, mouth and nose; followed by watery eyes, sneezing, and clear, watery nasal discharge. Sinus-type headache, emotional irritability, difficulty sleeping, red and swollen eyes and nasal mucous membranes, and a wheezing cough
seasonal atopic (allergic) rhinitis management
oral antihistamines (be aware of sedating side effect); decongestants (stimulating effect)
acute bronchitis etiology
usually occurs as an infectious winter disease that follows a common cold or other viral infection of the
respiratory tract. A secondary bacterial infection may follow this inflammation (from overexposure to air
pollution); fatigue, malnutrition, or becoming chilled could be predisposing factors
acute bronchitis s/sx
usually start with URI, nasal inflammation and profuse discharge, slight fever, sore throat and
back and muscle pains. A cough signals the beginning of bronchitis. At first the cough is dry, but within a few hours or days, a clear mucus secretion begins which becomes yellowish, indicating an infection.
acute bronchitis management
rest until fever subsides, drink 3-4 liters of water per day, and ingest an antipyretic analgesic, cough suppressant, and an antibiotic (when sever lung infection is present) on a daily basis
pneumonia etiology
infection of the alveoli and bronchioles that may be caused by viral, bacterial, or fungal
microorganisms; may also be caused by irritation from chemicals, aspiration of vomit, or other agents. Alveolar
spaces become filled with exudate, inflammatory cells, and fibrin
pneumonia s/sx
bacterial pneumonia = rapid onset, high fever with chills, pain on inspiration, decreased breath
sounds and rhonchi on auscultation, coughing up of purulent, yellowish colored sputum
pneumonia management
antibiotics (for bacterial pneumonia). Deep breathing exercises and removal of sputum through a
productive cough are helpful. Analgesics and antipyretics may be useful for controlling pain and fever.
bronchial asthma etiology
can be produced from a viral respiratory tract infection, emotional upset, changes in barometric pressure or temp, exercise, inhalation of a noxious odor, exposure to a specific allergen
bronchial asthma s/sx
spasm of the bronchial smooth muscles, edema, and inflammation of the mucous membrane
narrowing of airway and copious amounts of mucus produced
difficulty breathing could result in hyperventilation, resulting in dizziness
attack may begin with coughing, wheezing, SOB, fatigue
bronchial asthma management
reassure the athlete, give athlete medication, encourage athlete to drink water, have athlete perform controlled breathing, and relaxation exercises, remove environmental factor that may be causing attack
Exercise-Induced Bronchial Obstruction (Asthma) etiology
can be stimulated by exercise, or may be provoked only on rare occasions during moderate exercise. The exact cause in not clear. Loss of heat and water causes the greatest loss of airway reactivity. Sinusitis can also trigger an attack in an individual with chronic asthma
Exercise-Induced Bronchial Obstruction (Asthma) s/sx
airway narrowing caused by bronchial-wall spasm and excess production of mucus
chest tightness, breathlessness, coughing, wheezing, signs of nausea, hypertension, fatigue, respiratory stridor, headaches, redness of skin
occur within 3-8 minutes of strenuous activity
Exercise-Induced Bronchial Obstruction (Asthma) management
a regular exercise program, conditioning and running longer distances, exercise intensity and length should be graduated slowly, exercise in warm, humid conditions, albuterol (B2 agonist, acts for 2 hours)
Cystic Fibrosis etiology
genetic disorder that may manifest as: 1) a type of chronic obstructive pulmonary disease; 2) pancreatic
deficiency; 3) urogenital dysfunction; 4) increased electrolytes in sweat. Usually begins in infancy and is a major
cause of severe chronic lung disease in children (maximum life expectancy is 30 years)
Cystic Fibrosis s/sx
bronchitis, pneumonia, respiratory failure, gallbladder diseases, pancreatitis diabetes, and
nutritional deficiencies. Abnormally high production of mucus secretions in the lungs.
cystic fibrosis management
drug therapy (ibu) can help slow progression of disease; antibiotics used to control pulmonary disease. Constant postural drainage to mobilize secretions. High fluid intake, breathing of humidified air
Duchenne Muscular Dystrophy etiology
hereditary disease in which there is a degeneration of skeletal muscle with associated loss of strength. Muscle tissue is gradually replaced by adipose and fibrous connective tissue (connective tissue impedes circulation, which accelerates the degenerative process). Onset is usually between 2-10 years
Duchenne Muscular Dystrophy s/sx
problem manifests when child begins to walk; frequent falls and difficulty standing up; progressive degeneration hips legs abdominal and spinal musculature (muscles shorten as they atrophy, causing postural abnormalities)
Duchenne Muscular Dystrophy management
no cure; exercise to delay atrophy; death before age 20
Myasthenia Gravis etiology
autoimmine disease in which antibodies attack the synaptic junctions between nerves and muscles. Acetylcholine deficiency creates an abnormality that produces early fatigue in skeletal muscle (females 20-40 y)
Myasthenia Gravis s/sx
drooping of upper eyelid and double vision due to weakness in extraocular muscles. Difficulty
chewing and swallowing, weakness of the extremities, and general decrease in muscular endurance
Myasthenia Gravis management
drugs that inhibit breakdown of acetylcholine; corticosteroids to suppress immune system
Meningitis etiology
inflammation of the meninges that surround the spinal cord and brain (usually due to meningococcus bacteria = enter through the nose of throat). Causes swelling of the brain, enlargement of ventricles, and hemorrhage of the brain stem
