Infection and Sepsis ( 5 Questions)
Nosocomial infection is an infection that is acquired in a health care setting, such as a surgical site infection or a catheter-associated bloodstream infection. Nosocomial infections are often caused by multidrug-resistant organisms, such as methicillin-resistant Staphylococcus aureus (MRSA) or vancomycin-resistant Enterococcus (VRE).
Opportunistic infection is an infection that occurs in immunocompromised individuals, such as those with HIV/AIDS, cancer, or organ transplantation. Opportunistic infections are caused by microorganisms that are normally harmless or part of the normal flora, but become pathogenic when the host's defenses are weakened. Some examples of opportunistic infections are Pneumocystis jirovecii pneumonia, Candida albicans thrush, or cytomegalovirus retinitis.
Community-acquired infection is an infection that is acquired outside of a health care setting, such as a UTI caused by E. coli. E. coli is a common cause of UTI and is usually found in the intestinal tract or fecal matter.
Latent infection is an infection that remains dormant or inactive in the host for a period of time, but can reactivate and cause disease when the host's immunity declines. Some examples of latent infections are herpes simplex virus, varicella-zoster virus, or Mycobacterium tuberculosis.
Choice C reason: Community-acquired infection is an infection that is acquired outside of a health care setting, such as a UTI caused by E. coli. E. coli is a common cause of UTI and is usually found in the intestinal tract or fecal matter.
Choice A reason: Nosocomial infection is an infection that is acquired in a health care setting, such as a surgical site infection or a catheter-associated bloodstream infection. Nosocomial infections are often caused by multidrug-resistant organisms, such as methicillin-resistant Staphylococcus aureus (MRSA) or vancomycin-resistant Enterococcus (VRE).
Choice B reason: Opportunistic infection is an infection that occurs in immunocompromised individuals, such as those with HIV/AIDS, cancer, or organ transplantation. Opportunistic infections are caused by microorganisms that are normally harmless or part of the normal flora, but become pathogenic when the host's defenses are weakened. Some examples of opportunistic infections are Pneumocystis jirovecii pneumonia, Candida albicans thrush, or cytomegalovirus retinitis.
Choice D reason: Latent infection is an infection that remains dormant or inactive in the host for a period of time, but can reactivate and cause disease when the host's immunity declines. Some examples of latent infections are herpes simplex virus, varicella-zoster virus, or Mycobacterium tuberculosis.
