Tick the drug that can induce nausea, diarrhea, abdominal pain and rhinitis:

Correct Answer: D

Rationale: Failed to generate a rationale of 500+ characters after 5 retries.

Correct Answer: A

Rationale: Chronic bacterial infections typically trigger neutrophilia (A), an increase in neutrophils, as the primary innate immune response to bacterial pathogens. Basophilia (B) is rare and allergy-related, lymphocytosis (C) is viral or chronic lymphocytic leukemia-related, eosinophilia (D) is parasitic/allergic, and monocytosis (E) is more chronic inflammatory or mycobacterial—neutrophilia is the hallmark.

Correct Answer: B

Rationale: Hereditary spherocytosis results from defects in peripheral proteins (B) like spectrin or ankyrin, disrupting RBC membrane stability, leading to spherical shape and hemolysis. Integral protein defects (A) are less specific, rolealux (C) is a typo (likely ‘rouleaux,’ unrelated), sickle cells (D) are sickle cell disease, and decreased RBC size (E) isn’t causative—peripheral protein defects are key.

Correct Answer: C

Rationale: Platelets change shape (C, true) from discoid to spiky during aggregation, aiding clot formation. Initial vasoconstriction occurs (A, false), clotting factors enhance aggregation (B, false), serotonin contributes mildly (D, true but not primary), and thromboxane A2 promotes, not inhibits (E, false)—C is key.
