Question #46390
The Question
A 4-year-old patient is diagnosed with Severe Combined Immunodeficiency (SCID) caused by Adenosine Deaminase (ADA) deficiency. If a sample of the patient's lymphatic fluid is analyzed prior to any enzyme replacement or gene therapy, which of the following statements would be INCORRECT regarding its composition and physiological role?
Options
- A.
It will exhibit a severe depletion of specialized lymphocytes due to the toxic accumulation of deoxyadenosine.
- B.
It will show a marked decrease in total protein and lipid content due to the systemic atrophy of lymphoid organs.
- C.
It will maintain a mineral distribution similar to that of blood plasma, despite being immunologically compromised.
- D.
It will continue to successfully transport absorbed dietary fats from the intestinal lacteals to the venous circulation.

Why This Question Is Tricky
Common Mistakes
The 'Conceptual Pivot' is distinguishing between the cellular components of lymph (lymphocytes) and the acellular/chemical components (plasma proteins, absorbed lipids, minerals).
Students often harbor the misconception that a systemic immune failure (like SCID) degrades the entire lymphatic fluid, failing to realize that lymph formation is a passive cardiovascular filtration process independent of lymphocyte viability.
