SHS 401 FINAL EXAM QUESTIONS AND
ANSWERS WITH FULL A+ SOLUTIONS,
UPDATED 2026, SUCCESS ASSURED
Q: What is a "Disorder"? ANSWER: A functional abnormality of some kind.
✔✔
Context: A disorder implies that a part of the body or a system is not
performing its intended job correctly, regardless of whether a physical
change is visible.
Q: What is a "Lesion"? ANSWER: A pathological traumatic discontinuity of
tissue or loss of function. ✔✔
Interpretation: This means the system is not functioning normally due to
damage. A lesion can be a wound, a tumor, an ulcer, or even a localized area
of cellular death.
Scales of Observation
Lesions are categorized by the level of magnification required to see them.
Q: What is a "Gross" or "Macroscopic" lesion? ANSWER: A lesion visible to
the naked eye. ✔✔
Example: A large bruise, a skin tear, or a visible tumor on an organ during
surgery.
Q: What is a "Histologic" or "Microscopic" lesion? ANSWER: A lesion that
is only visible under a light microscope. ✔✔
Process: This usually requires taking a biopsy (a tissue sample), staining it,
and examining the cellular structure.
Q: What is a "Molecular" lesion? ANSWER: A lesion that can only be seen
under a high-power microscope (Electron Microscope). ✔✔
, Technical Detail: These occur at the level of individual molecules or
organelles within a cell, such as damage to the DNA strand or a malfunction
in the mitochondria.
Distribution of Lesions
When describing where a lesion is located, specific terms indicate how widespread
the issue is:
Q: What does "Focal" mean? ANSWER: A lesion limited to a small, specific
area. ✔✔
Opposite Term: Diffuse, which means the abnormality is spread throughout
an entire organ or tissue type.
What does diffuse mean? -ANSWER✔✔A lesion that covers a wide area
What is a systemic lesion? -ANSWER✔✔A lesion that effects form and function
of an entire system supposed to just one part of it
What is a structural lesion? -ANSWER✔✔A lesion that changes the physical or
anatomical construct of the organ or system
What is a depressive lesion? -ANSWER✔✔Lesions that result in a decrease in
function that can vary in severity
What is a destructive lesion? -ANSWER✔✔A lesion that normally leads to
obliteration of an organ/ complete damage of that function
What is a degenerative lesion? -ANSWER✔✔A lesion that causes deterioration of
a mechanism or function over time
