Fever Flashcards
Pneumonia
. Infection that inflames the air sacs in one or both lungs
. Air sacs may fill with fluid or pus causing cough with phlegm or pus
Pneumonia signs and symptoms
Fever or hypothermia, tachypnea, cough, dyspnea, bronchial sounds or crackles on auscultation
Tachypnea
Rapid breathing
Dyspnea
Difficult or labored breathing
Pneumonia etiology
Viral, bacterial, fungal
Acute lymphocytic leukemia (ALL)
Cancer of the blood and bone marrow, common in kids
Signs and symptoms of ALL
Fever, bleeding from gums, easy bruising, loss of appetite, night sweats, weight loss
Pyelonephritis
. Infection of renal pelvis and kidney
. Results from ascent of bacterial pathogen up ureters from bladder to kidneys
Signs and symptoms of pyelonephritis
Fever, flank pain, painful urination (dysuria), urinary frequency
Pyelonephritis nephrology
Escherichia Coli, Proteus, Klebsiella, Enterobacter
Bacteremia
Presence of bacteria in blood
Signs and symptoms of bacteremia
Fever and chills, nausea, vomiting, loss of appetite, skin rash
Bacteremia etiology
Gram-negative and gram-positive organisms both aerobic and anaerobic
Influenza
Viral infection that attacks resp. System
Influenza signs and symptoms
. Fever, chills, malaise, cough, Coryza, and myalgias
. Elderly present with confusion w/o fever
Influenza etiology
influenza A, B, or C
Coryza
Upper respiratory tract inflammation
Myalgias
General discomfort
Influenza route of transmission
Respiratory droplet nuclei
ROS list
. General . Skin . HEET . Neck . Breasts . Resp. . Cardio . GI . Peripheral vascular . Urinary . Genital . Musculoskeletal . Psychiatric . Neurological . Hematologists . Endocrine
What does SOS stand for?
Structure (anatomy), Organs (systems), and Science (pathophysiology)
Structure relating to illness discovery
Think about anatomy superficial to deep and what potential issues could arise
Organs (systems) in relation to illness discovery
Think about how the different body systems work together and what would happen if a particular body system malfunctioned
Science (pathophysiology) in regards to illness discovery
Think about how things normally function and what a possible disease could be based on previous scientific knowledge
Fever
Abnormal elevation of core body temp.
Body temp is normally ____
37 degrees C (98.6 degrees F)
Prexia is a temp of ___
38 C or higher (100.4 F)
Hyperprexia is is a temp of ____
41.6 C or higher (106 F)
Hypothermia is a temp of ____
35 C or lower (95 F)
Physiology of a fever
. Fever reflects change in hypothalamic setpoint
. Bacterial infection signals immune rxn and necrosis
. TNF and IL-1 are released causing NE and arachidonic acid to be released from hypothalamus signal
. PGE2 is released increases temp causing fever, vasoconstriction, and muscle shivering
Fever’s role in disease
Inc. blood vessel size -inc. blood vol. - inc. metabolism - inc. immune rxns, chemotactic, phagocytic, and bactericidal activity of polymorphonuclear leukocytes - slows down proliferation of microorganisms
Oral temp compared with core body temp
. Usually lower than core body and rectal by 0.5-0.7 C (0.7-0.9 F)
. higher than auxiliary temp by 1 degree
Etiology of fever
Infection, cancer, withdrawal, rheumatologic disease, endocrine, allergy, fever of unknown origin (FUO), drug reaction, trauma
Complications of fever
. Dehydration/electrolyte and glucose abnormality
. Mental status change/delirium
. Neurotoxic effect/seizure
Low grade fever temp.
. 100.5-102.1 F
. 38.1-39 C
Moderate fever temp
. 102.2-104.0 F
. 39.1-40 C
