SCIDs (Severe Combined Immune Deficiency Syndrome) is most like which other disease?
Systemic Lupus Erythematosus
DiGeorge Syndrome
AIDS
Chronic Granulomatous Disease
The Correct Answer is C
Choice A reason: Systemic Lupus Erythematosus is an autoimmune disease causing tissue damage via autoantibodies, not a primary immunodeficiency. SCIDs involves defective T- and B-cell function, unlike lupus’s immune hyperactivity, making this an incorrect comparison to SCIDs.
Choice B reason: DiGeorge Syndrome involves T-cell deficiency due to thymic hypoplasia but typically spares B-cell function. SCIDs affects both T- and B-cells, leading to broader immune failure, making it less similar to DiGeorge’s partial defect.
Choice C reason: SCIDs, like AIDS, causes profound immunodeficiency, impairing T- and B-cell function, leading to severe infections and opportunistic pathogens. Both result in similar immune vulnerability, though SCIDs is genetic and AIDS is acquired, making this the correct comparison.
Choice D reason: Chronic Granulomatous Disease impairs phagocyte function, causing recurrent bacterial and fungal infections, but spares lymphocyte function. SCIDs primarily affects T- and B-cells, leading to broader immune defects, making this less similar to SCIDs.

Correct Answer is A
Explanation
Choice A reason: Hyperventilation causes decreased CO2 levels (respiratory alkalosis) due to rapid breathing from pain, anxiety, or restlessness. This matches the patient’s symptoms and blood gas results, making it the correct cause.
Choice B reason: Nephrolithiasis causes pain but doesn’t typically lead to hyperventilation or low CO2. Respiratory alkalosis from hyperventilation better explains the findings, so this is incorrect for the cause.
Choice C reason: Acute fracture causes pain but not necessarily hyperventilation or low CO2. Anxiety-driven hyperventilation is more likely to cause respiratory alkalosis, so this is incorrect for the primary cause.
Choice D reason: Urinary tract infection may cause discomfort but not low CO2 or hyperventilation. Anxiety and pain causing hyperventilation align with the blood gas, so this is incorrect.
Correct Answer is B
Explanation
Choice A reason: Necrotic bladder implies tissue death, not a nerve-related obstruction. Neurogenic bladder, caused by nerve supply interruption, leads to functional obstruction, making this incorrect for the described condition.
Choice B reason: Neurogenic bladder results from nerve supply interruption, causing dysfunctional bladder control and obstruction. This matches the description of a functional urinary tract issue, making it the correct term.
Choice C reason: Retrograde bladder is not a medical term; retrograde refers to urine backflow. Neurogenic bladder accurately describes nerve-related obstruction, so this is incorrect for the condition.
Choice D reason: Obstructed bladder is vague and not specific to nerve issues. Neurogenic bladder directly addresses nerve supply disruption causing obstruction, making this incorrect for the term.
