Which statement made by the patient newly diagnosed with systemic lupus erythematosus indicates a need for further teaching about the course and management of this disease? a) "I will take my medication even if my symptoms improve." Ob) "I will not have my hair dyed, frosted, or permed unless I am in a period of remission." Oc) "I will report any fever to my healthcare provider immediately." d) "I will sunbathe as often as possible to ensure I get enough vitamin D."
Pathogenic infections induce damage to the host by a variety of mechanisms. While many mechanisms are direct effects of the pathogen, some damaging mechanisms result from the immune response to the infection. Examples of damage caused by the host immune response are: a) Exotoxin production, endotoxin b) Cell-mediated inmunity, direct cytopathic effect c) Endotoxin, inmmunune complexes d) Direct cythopathic effect, endotoxin e) Cell-mediated inmunity, inmmunune complexes
All the following would be of benefit to extracellular pathogens, except A) O the presence of a capsule B) O ability to prevent the fusion of a phagosome and lysosome C) O ability to prevent of opsonization D) O ability to alter cell surface proteins via phase variation E) O There are no exceptions; all are of benefit to extracellular pathogens.
