Q

Describe the chain of infection (E.R.P.M.P.S.)

A

E - etiologic agent. pathogen with virulence and ability to infiltrate the host and live in the host body
R - reservoir. where the organism usually resides. Includes patient’s own microorganisms from other parts of their body, other humans, plants, animals, and the environment
P - portal of exit. nose, mouth, vagina, anus, and open wounds (people are the most common source of infection for themselves and for others)
M - mode of transmission. direct, indirect, or airborne transmission
P - portal of entry. mouth, cuts in the skin, eyes, nose
S - susceptible host. ANYONE! mostly elderly, infants, and immunocompromised at risk

24
Q

T or F: everyone who is infected with TB will develop the disease

A

False
(If the pt has an adequate immune response to tb bacilli, then scar tissue develops around the tubercle and the bacilli remain enclosed, these lesions will then calcify (they might be visible on an x-ray), but the pt will not develop the Tb disease)

Q

T or F: TB pneumonia is the result of infected tubercles that rupture and spread the bacilli.

A

True

Q

What diagnostics are used for T?

A

Q

Risk factors for cellulitis

  • Reduced physical activity
  • diabetes mellitus
  • obesity
  • peripheral vascular disease
  • tinea pedis
  • Weakened immune system
  • Malnutrition
