Ch 48: Peds Infectious Diseases Flashcards
Rubeola (Measles)
Agent: Paramyxovirus
Incubation Period: 10 - 20 dys
Communicable Period: 4 dys before - 5 dys after rash appears, mainly during prodromal stage.
source: respiratory tract secretions, blood, or urine of infected person
transmission: airborne particle or direct contact with infectious droplets; transplacental
prodromal
pertaining to early sxs that may mark the onset of disease
Rubeola (Measles) 3 C’s of assessment
coryza (inflammation of nasal cavity mucous membranes)
cough
conjunctivitis
Koplik’s spots (small red spots with a bluish white center and red base - buccal mucosa, last 3 dys)
Rubeola (Measles) rash
red, erythematous maculopapular eruption
starts on the face and spreads downward to the feet
blanches easily w pressure and gradually turns a brownish color (lasts 6-7 dys)
may have desquamation
Rubeola (Measles) interventions
droplet precautions in the hospital
Roseola (exanthema subitum)
agent: human herpesvirus type 6 incubation period: 5 - 15 dys communicable period: unk. (thought to be from febrile stage - rash appearance) source: unk transmission: unk
Roseola (exanthema subitum) assessment
sudden high (>102) fever of 3 - 5 dys duration in a child who appears well, followed by a rash (rose pink macules that blanch w pressure) rash appears several hrs - 2 dys afte rthe fever subsides, lasts 1 - 2 dys
Rubella (German Measles)
agent: rubella virus
incubation period: 14 - 21 dys
communicable period: from 7 dys before to 5 dys after rash appears
source: nasopharyngeal secretion; virus is also present in blood, stool, and urine
transmission: airborne / direct contact w infection droplets; indirectly via articles freshly contaminated with nasopharyngeal secretions, feces, or urine; transplacental
Rubeola
Measles
Rubella
German Measles
Rubella (German Measles) assessment
low grade fever
malaise
pinkish red maculopapular rash: begins on the face and spread to the entire body w/in 1 -3 dys
petechial red, pinpoint spots may occur on the spots palate
Rubella (German Measles) interventions
airborne droplet precautions if the child is hospitalized
isolate infected child from pregnant women
Mumps
AGENT: paramyxovirus
INCUBATION PERIOD: 14 - 21 dys
COMMUNICABLE PERIOD: immediately before and after parotid gland swelling begins
SOURCE: saliva of infected person and possibly urine
TRANSMISSION: direct contact or droplet spread from an infected person
Mumps assessment
fever headache and malaise anorexia jaw or ear pain aggravated by chewing, followed by parotid glandular swelling orchitis (swelling of testicles)
Mumps interventions
airborne droplet precautions
bedrest until parotid gland swelling subsides
avoid food you need to chew
hot/cold compresses as prescribed to the neck
warmth and local support with snug underpants to relieve orchitis
Chickenpox (varicella)
AGENT: varicella-zoster virus
INCUBATION PERIOD: 13 - 17 dys
COMMUNICABLE PERIOD: 1 - 2 dys before the onset of the rash to 6 dys after the first crop of vesicles, when crusts have formed
SOURCE: respiratory tract secretions of infected peron; skin lesions
TRANSMISSION: direct contact, droplet (airborne) spread, and contaminated objects
Chickenpox (varicella) assessment
slight fever, malaise, and anorexia
followed by macular rash that first appears on the trunk and scalp and moves to the face and extremities
lesions become pustules, begin to dry, and develop a crust
lesions may appear on the mucous membranes of the mouth, the genital area, and the rectal area
Chickenpox (varicella) interventions
strict isolation (contact and droplet precautions)
Pertussis (whooping cough)
AGENT: Bordetella pertussis
INCUBATION PERIOD: 5 - 21 dys (usually 10)
COMMUNICABLE PERIOD: greatest during catarrhal stage (when discharge from resp secretions occurs)
SOURCE: discharge from the resp tract of the infected person
TRANSMISSION: direct contact or droplet spread from infected person; indirect contact with freshly contaminated articles
catarrhal stage (pertussis)
when discharge from respiratory secretions occurs
Pertussis (whooping cough) assessment
sxs of resp infection followed by increased severity of cough, with a loud whooping inspiration
may experience cyanosis, resp distress, and tongue protrusion
listlessness, irritability, anorexia
Pertussis (whooping cough) interventions
isolate child during catarrhal stage
airborne droplet precautions
admin antimicrobial therapy as rx.
reduce environmental factors that cause coughing
ensure adequate nutrition / hydration
provide suction + humidified oxygen if needed
monitor cardiopulmonary status and pulse oximetry
infants do not receive maternal immunity to pertussis
Diphtheria
AGENT: Corynebacterium diphtheriae
INCUBATION PERIOD: 2 - 5 dys
COMMUNICABLE PERIOD: variable, until virulent bacilli are no longer present (3 negative cultures of discharge fromt he nose and nasopharynx, skin, and other lesions) - usually 2 wks, can be 4 wks
SOURCE: dischargef romt he mucous membrane of the nose and nasopharynx, skin, and other lesions of the infected person
TRANSMISSION: direct contact w infected person, carrier, or contaminated articles
Diphtheria assessment
low grade fever, malaise, sore throat
foul smelling, mucopurulent nasal discharge
dense pseudomembrane formation of the throat that may interfere w eating, drinking, and breathing
lymphadenitis, neck edema, “bull neck”
Diphtheria interventions
strict isolation
admin diphtheria antitoxin as prescribed (after a skin or conjunctival test to rule out sensitivity to horse serum)
bedrest
admin abx as prescribed
provide suction and humidified oxygen as needed
provide tracheostomy care if necessary
