Aspirin can prevent inappropriate blood clotting in the following ways except:
Aspirin can reduce unwanted platelet adhesion by inhibiting TXA2 synthesis
Platelet aggregation can be reduced through inhibition of prostaglandin production by aspirin
Aspirin inhibits the conversion of fibrinogen into fibrin and consequent platelet plug formation
Aspirin helps to inhibit ADP action and minimizes platelet plug formation
The Correct Answer is C
Choice A reason: Aspirin inhibits TXA2 synthesis, reducing platelet adhesion and clotting. This is a true mechanism of aspirin’s antiplatelet effect, so it’s incorrect as the exception.
Choice B reason: Aspirin reduces prostaglandin production, which decreases platelet aggregation. This is a valid antiplatelet mechanism, so it’s incorrect for the action aspirin does not perform.
Choice C reason: Aspirin does not inhibit fibrinogen-to-fibrin conversion; this is part of the coagulation cascade, not platelet function. Aspirin targets platelets, making this the correct action it doesn’t perform.
Choice D reason: Aspirin inhibits ADP-induced platelet aggregation, minimizing plug formation. This is a true antiplatelet effect, so it’s incorrect as the action aspirin does not do.

Correct Answer is ["B","C","D"]
Explanation
Choice A reason: Red blood cells are not a direct measure of inflammation; they assess anemia or oxygen-carrying capacity. Inflammation is measured by WBC, ESR, and fever, which reflect immune activity and systemic response, so this is incorrect for inflammation measurement.
Choice B reason: White blood cells (WBC) increase during inflammation (leukocytosis), indicating immune activation. This is a standard laboratory measure of inflammatory processes, making it a correct choice for assessing inflammation in clinical practice.
Choice C reason: Erythrocyte sedimentation rate (ESR) measures how quickly red blood cells settle, rising with inflammation due to increased proteins. It’s a common marker for inflammatory conditions, making it a correct selection for measuring inflammation.
Choice D reason: Fever is a clinical sign of inflammation, driven by cytokines like IL-6. It’s a systemic response measured via temperature, making it a correct choice for assessing inflammation alongside laboratory markers like WBC and ESR.
Correct Answer is C
Explanation
Choice A reason: Appendicitis typically causes diarrhea or reduced bowel movements, not constipation with gastric distention. Hyperthermia and tachycardia are common due to inflammation, so this is incorrect for appendicitis manifestations.
Choice B reason: Appendicitis is associated with leukocytosis, not leukopenia, reflecting infection. Constipation is less common than diarrhea or pain, so hyperthermia and tachycardia better match, making this incorrect.
Choice C reason: Appendicitis causes hyperthermia (fever) from infection and tachycardia from pain and inflammation. These are classic manifestations, aligning with the body’s response to appendiceal inflammation, making this the correct choice.
Choice D reason: Hypothermia and bradycardia are not typical in appendicitis; fever and increased heart rate occur due to infection. Hyperthermia and tachycardia are expected, so this is incorrect for appendicitis symptoms.
