This chapter introduces microorganisms, differentiating between pathogenic and non-pathogenic types, and highlights factors increasing infection susceptibility. It emphasizes the nurse's role in preventing infection spread and introduces medical and surgical asepsis.
| Concept/Term | Definition/Description | Clinical Significance | Key Points |
|---|---|---|---|
| Microorganism | Tiny living entities | Can be pathogenic or non-pathogenic | Some can be detrimental, like C. difficile |
| Medical Asepsis | Clean technique | Inhibits growth/transmission of pathogens | Hand hygiene, changing linens |
| Surgical Asepsis | Sterile technique | Destroys all microorganisms and spores | Used in OR, invasive procedures |
| Chain of Infection | Cycle of infection | Must be broken to prevent infection | Includes infectious agent, reservoir, portal of exit, mode of transmission, portal of entry, susceptible host |
Question: A nurse is preparing to insert a urinary catheter. Which of the following actions demonstrates surgical asepsis? A) Using clean gloves B) Cleaning the perineal area with soap and water C) Using sterile gloves and a sterile catheter D) Ensuring the patient has privacy
Answer: C Explanation: Surgical asepsis, or sterile technique, is required for invasive procedures like catheter insertion to prevent infection. Sterile gloves and a sterile catheter are essential.
This chapter explores infectious agents like bacteria, viruses, fungi, and protozoa, discussing their characteristics and requirements for survival. It also addresses factors such as strength in numbers, the host's immune system, and length of exposure.
| Concept/Term | Definition/Description | Clinical Significance | Key Points |
|---|---|---|---|
| Bacteria | Single-celled microorganisms | Can be aerobic or anaerobic | Three basic shapes: cocci, bacilli, spirilla |
| Virus | Smallest known agents causing disease | Antibiotics are ineffective | Reproduce rapidly inside cells |
| Fungi | Plant kingdom organisms | Cause infections of skin, hair, nails | Examples: Candida, Aspergillus |
| Protozoa | Single-celled animals | Responsible for malaria, amebic dysentery | Found in GI, GU, circulatory, respiratory tracts |
| Culture & Sensitivity | Growing and testing bacteria | Identifies bacteria and effective antibiotics | Should be done before starting antibiotics |
Question: A patient has a wound infection. The physician orders a culture and sensitivity. What is the primary purpose of the sensitivity test? A) To identify the type of bacteria present B) To determine the patient's white blood cell count C) To determine which antibiotics will be most effective against the bacteria D) To assess the extent of tissue damage
Answer: C Explanation: Sensitivity testing determines which antibiotics are most effective in killing the identified bacteria, guiding appropriate treatment.
This chapter outlines tools and practices for preventing and controlling infections, including disinfection, antiseptics, cleaning protocols, hand hygiene, and spill management.
| Concept/Term | Definition/Description | Clinical Significance | Key Points |
|---|---|---|---|
| Disinfection | Chemical applied to objects to destroy microorganisms | Reduces the number of pathogens | Does not kill spores |
| Antiseptic | Substance inhibiting microorganism growth | Used on human tissue | Examples: alcohol, iodine |
| Hand Hygiene | Using soap & water or hand-gel | Single most important preventive technique | Wash for 15-20 seconds |
| Spill Management | Cleaning blood/body fluid spills | Prevents spread of infection | Use 10% bleach solution |
Question: After assisting with a patient procedure, a nurse notices a small blood spill on the floor. What is the most appropriate action? A) Ignore the spill as it is small B) Cover the spill with a paper towel C) Clean the spill immediately with a 10% bleach solution D) Call housekeeping to clean the spill later
Answer: C Explanation: Blood spills should be cleaned immediately with a 10% bleach solution to prevent the spread of infection.
