Clinical Assessment Techniques and Pathogen Types
Physical Examination Techniques
- Inspection: Consists of a patient’s visual examination. It can also sometimes include the use of one’s sense of smell.
- Palpation: The act of touching a patient with different parts of your hands to detect signs like masses, swelling, or areas of pain. Palpation can be light (done by using your fingertips) or deep (done with other parts of your hands to reveal information about areas of discomfort or the position of certain organs). This technique is frequently used to assess the patient’s abdominal area.
- Percussion: The act of tapping on a surface and listening to the resulting sound to determine the characteristics of an underlying structure (for example, the presence of air, solid masses, etc.). This technique is frequently used to examine the abdominal area.
- Auscultation: A procedure consisting of listening to an area of the body directly with our ear or with a mechanical device which produces amplification, like the stethoscope (widely used to listen to lungs, heart, or bowel sounds).
Senses Used in Clinical Assessment
- Sight: Vision
- Smell: Olfaction
- Touch: Palpation
- Hearing: Audition

Classification of Pathogenic Microorganisms
- Bacteria: Single-celled prokaryotic organisms that lack a nucleus. They can be beneficial (like gut flora) or pathogenic, and are typically treated with antibiotics.
- Fungi: Eukaryotic organisms that include yeasts, molds, and mushrooms. They obtain nutrients by decomposing organic matter and can cause infections like athlete’s foot or candidiasis.
- Viruses: Non-living infectious agents consisting of genetic material (DNA or RNA) encased in a protein coat. They can only replicate by hijacking the machinery of a living host cell.
- Protists: A diverse group of eukaryotic microorganisms that do not fit into the animal, plant, or fungi kingdoms. Examples include amoebas and the parasites that cause malaria.
- Prions: Misfolded proteins that lack genetic material. They trigger normal proteins in the brain to fold abnormally, leading to fatal neurodegenerative diseases like “Mad Cow Disease.”
- Multicellular Parasites: Organisms composed of many cells that live on or inside a host to survive. This category primarily includes helminths (worms) like tapeworms and roundworms.
