Question 5 • Introduction to Health Science - EL3601 B
Tana, a medical student, is analyzing a tissue specimen under a microscope and sees a microorganism that she thinks is causing the patient’s illness. Her instructor tells her that she is incorrect. What was most likely the medical student’s error?
Answer
A
The student identified the microorganism as a fungus, which cannot be seen under a microscope.
B
The student identified the microorganism as a virus, which cannot be seen under a microscope.
C
The student identified the microorganism as a parasite, which is not harmful.
D
The student identified the microorganism as a virus, which is not harmful.
Explanation
Viruses are much smaller than fungi and parasites, so they generally cannot be seen with a standard light microscope. They can be observed with specialized tools such as an electron microscope, but the question most likely assumes an ordinary microscope. Therefore, the likely error was identifying the microorganism as a virus that could be seen in the specimen.
