Q

Principles of CD Nursing

A
  1. There are various types of organism causing disease
  2. Organisms can be transmitted from one person to another through direct or
    indirect contact.
  3. Concurrent disinfection is essential to destroy organisms coming from fresh
    body secretions of infected persons.
  4. There are environmental conditions conducive to production, growth and
    multiplication of pathogens.
  5. There are specific incubations periods for the communicability of diseases.
  6. Isolation procedures should always be practiced.

Emerging Problems in Infectious Disease:

A
  1. Increase in the number of microorganisms that are developing resistance to
    increasing numbers of available antimicrobials.
  2. Increasing number of persons in state of immunosuppression.
  3. Persons with serious disease are living longer and are exposed to more aggressive
    surgical procedures.
  4. The use of indwelling lines and implanted foreign bodies has increased, thus
    rendering these patients more susceptible to infections.
