Question

question 4
histo/plasmo/sis is characterized by:
○ spleen and liver enlargements
○ leukopenia
○ lymphadenopathy
○ all of the above

question 5
colds are treated symptomatically, which means:
○ symptoms are unobservable
○ symptoms run their course
○ symptoms are ignored
○ symptoms are treated with medications

question 6
cystic fibrosis is an inherited exocrine gland disorder that causes thick secretions of ______ to accumulate in the lungs.
○ sweat
○ bile and pus
○ saliva and pus
○ mucus and pus

Explanation:

• Question 4: Histoplasmosis is a fungal infection. It can cause splenomegaly (spleen enlargement), hepatomegaly (liver enlargement), leukopenia (low white blood cell count), and lymphadenopathy (swollen lymph nodes). So all the options are correct.
• Question 5: Symptomatic treatment means treating the symptoms (e.g., using a decongestant for a stuffy nose) rather than the underlying cause (the cold - causing virus). The symptoms are not ignored, they are observable, and we do not just let them run their course without any intervention (in terms of symptom - relief).
• Question 6: Cystic fibrosis affects the exocrine glands. In the lungs, it causes thick mucus and pus to accumulate due to the defective chloride channel (CFTR), leading to problems with mucus clearance and recurrent infections.

Answer:

• Question 4: D. All of the above
• Question 5: D. symptoms are treated with medications
• Question 6: D. mucus and pus
