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 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","C","D","E"]
Explanation
Choice A reason: Hydration is a treatment, not a complication. Rhabdomyolysis, hyperkalemia, and AKI are complications of crush injuries, with kidney function monitoring essential. This describes an intervention, not a complication, so it’s incorrect.
Choice B reason: Rhabdomyolysis is likely from severe muscle trauma in a crush injury, releasing myoglobin and electrolytes, risking kidney damage. This matches the patient’s injury, making it a correct complication.
Choice C reason: Electrolyte monitoring, especially potassium, is critical due to hyperkalemia risk from muscle breakdown. This can cause arrhythmias, making it a correct selection for complications.
Choice D reason: Acute kidney injury (AKI) is common in rhabdomyolysis, as myoglobin damages kidneys. Given the crush injury, AKI is likely, making this a correct complication.
Choice E reason: Monitoring kidney function (creatinine, BUN, urine output) detects AKI from rhabdomyolysis. This ensures timely intervention, making it a correct choice for complications.
