Cheat Sheet
- Chain of Infection Essentials -
Preventing the spread of infections is foundational to breaking the chain of infection, which comprises six links: reservoir, pathogen, portal of exit, mode of transmission, portal of entry, and susceptible host. Use the mnemonic "RIP-PSH" to remember each link. Interrupting any one link - such as by isolating a reservoir or using barriers - halts pathogen transmission (CDC).
- "Germs" as a Nonscientific Synonym -
In everyday and patient-friendly language, "germs" is the nonscientific synonym for disease-producing organisms, encompassing bacteria, viruses, fungi, and protozoa. Reinforce that "germs" still require precise control measures like hand hygiene and surface disinfectants. Framing pathogens as "germs" helps learners recall key prevention strategies in nontechnical settings (WHO).
- Bacteria Types and Gram Stain -
Bacteria are broadly classified into Gram-positive (purple) and Gram-negative (pink) based on cell-wall structure revealed by the Gram stain. Remember "Purple Positives, Pink Negatives" to sort cocci vs. bacilli shapes in clinical labs. Accurate identification guides antibiotic choice and infection control measures (American Society for Microbiology).
- Disinfectant Dilutions and Contact Time -
Effective disinfection depends on correct concentration - for example, a 1:10 bleach solution (1 part bleach to 9 parts water) with 10 minutes of wet contact time. Use a simple formula: C1V1=C2V2 to calculate dilutions. Always verify the manufacturer's instructions for each surface and pathogen type to ensure efficacy (EPA).
- Hand Hygiene & PPE Protocols -
Hand hygiene using alcohol-based rubs for ≥20 seconds or soap-and-water for ≥40 seconds is a top infection prevention best practice outlined in WHO's "5 Moments." Don and doff PPE in the order: gown, mask, goggles, gloves (reverse for removal) to avoid self-contamination. Practice the "Clean In, Dirty Out" rule to keep patients and yourself safe (CDC).
