Study Notes

Assessment in Infection Control

Nurses assess patients' defense mechanisms, susceptibility, and infection knowledge.
Disease history review with patients and families can reveal exposure to communicable diseases.
Clinical condition evaluation allows detection of infection signs or risk factors.
Laboratory findings can inform nurses about patients' defenses against infection.
Understanding susceptibility factors aids in planning preventive therapies, including aseptic techniques.
Early recognition of infection signs enables timely alerts to the healthcare team for potential therapy needs.

Status of Defence Mechanisms

Review of physical assessment findings helps determine patients' normal defense mechanisms.
Breaks in the skin present potential entry points for infections.
Chronic smoking increases the risk of respiratory infections post-surgery due to impaired mucus clearance.
A reduction in primary or secondary defenses elevates infection risk.

Patient Susceptibility

Various factors influence patient susceptibility to infections.
Recognition of risk factors is crucial for effective infection prevention.

Inadequate Primary Defences

Skin or Mucosa: Damage allows microbial entry.
Traumatized Tissue: Higher susceptibility from compromised tissues.
Decreased Ciliary Action: Impairs lung clearance, increasing respiratory infection risk.
Obstructed Urine Outflow: Can lead to urinary tract infections.
Altered Peristalsis: Disruption can predispose to gastrointestinal infections.
pH Changes: Altered secretions can inhibit natural defense mechanisms.
Decreased Mobility: Mobility reduction can contribute to infection risks.

Inadequate Secondary Defences

Reduced Hemoglobin Levels: Limits oxygen delivery to tissues, affecting healing and defense.
Suppressed WBCs: Medications or diseases can lower infection-fighting capabilities.
Suppressed Inflammatory Response: May hinder the body's initial response to injury or infection.
Low WBC Count (Leukopenia): Diminishes the overall immune response, increasing susceptibility to infections.
