Chapter 29 - Additional General Medical Conditions Flashcards
(174 cards)
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
influenza management
bed rest and supportive care (avoid aspirin for under 18 years - Reyes syndrome)
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)
