A patient has a chronic digestive disease characterized by intermittent abdominal pain in the right lower quadrant, diarrhea, and loss of appetite. This condition is sometimes referred to as regional enteritis. Which condition does this patient have?
GERD
Crohn disease
Peptic ulcers
Pancreatitis
The Correct Answer is B
A. GERD (Gastroesophageal Reflux Disease):
GERD causes heartburn and regurgitation, not RLQ pain or diarrhea.
B. Crohn disease:
Crohn's disease (regional enteritis) causes chronic inflammation that can affect any part of the GI tract, often terminal ileum (RLQ pain), with diarrhea and weight loss.
C. Peptic ulcers:
Peptic ulcers cause epigastric pain, typically related to meals, not chronic RLQ pain or diarrhea.
D. Pancreatitis:
Pancreatitis causes epigastric pain radiating to the back, not right lower quadrant pain or chronic diarrhea.

Correct Answer is B
Explanation
A. They bind to infected cells and are activated by cytokines:
This describes cytotoxic T cells (CD8+ cells), which kill infected cells, not helper T cells.
B. They activate B cells and produce small cells called cytokines:
Helper T cells (CD4+ cells) stimulate B cells to produce antibodies and secrete cytokines to coordinate the immune response.
C. They destroy infected cells by producing proteins targeting cell membranes:
Again, this is the role of cytotoxic T cells, not helper T cells.
D. They are non-responsive during active infections:
Helper T cells are highly active during infections, directing other immune cells. They are not non-responsive.
Correct Answer is C
Explanation
A. Alkalosis and insomnia:
Alkalosis does not trigger sickling; acidosis (low pH) is more harmful. Insomnia alone is not a direct trigger.
B. Reduced stress and warm environmental temperature:
Reduced stress and warmth help prevent crises rather than cause them.
C. Acidosis and dehydration:
Acidosis promotes sickling of RBCs, and dehydration increases blood viscosity, both triggering vaso-occlusive crises.
D. High fat diet and hyperoxia:
A high-fat diet is linked to cardiovascular disease, and hyperoxia (excess oxygen) is not a trigger for sickling.
