Infection

P. 101

A

• Invasion of pathogens into tissue cells. Pathogens successfully invades the body and begins to replicate.

  ▪ May be localized (e.g., a toe)
  ▪ Spread regionally (e.g., a leg)
  ▪ Become systemic (i.e., Throughout the entire body)

Q

Methicillin-Resistant Staphylococcus aureus Infection (MRSA)

P. 135

A

Is a bacterial staph infection that is essentially unaffected by certain antibiotics.

  • MRSA is spread from one person to another by direct contact with the infection, such as touching a skin bump or infection that is draining pus. MRSA can be spread directly, for example, by touching an infected person’s Rash, or it can be spread indirectly, such as by touching a used bandage contaminated with MRSA or by sharing a towel or razor that has come in contact with infected skin.
  • One of the most frequent anatomical sites of MRSA colonization is the nose; bacteria can be found in the nasal secretions.
35
Q

Meningitis

P. 121

A

Is the inflammation of the meningeal membranes of the brain and/or the spinal cord.

• 6 can be caused by a bacterial pathogen. , such as meningococcus; however, it is more often the result of a viral infection.

36
Q

The Human body is designed to alert the individual and the doctor to the existence of infection by exhibiting specific signs and symptoms:

(P. 101)

A
  • Increased body temperature (Commonly known as a fever).
  • Increased white blood cell count.
  • Increase (tachycardia) or decrease (bradycardia) in heart rate.
  • Increase (hyperventilation) or decrease (dyspnea) in respiratory rate.
37
Q

These are methods of transportation for bacteria or viruses to travel from an infected person to another soon-to-be-infected person:

(P. 102 and 103)
