Answer to Question 1
ANS: D
This patient shows signs of salicylism, which occurs when ASA levels climb just slightly above therapeutic level. Salicylism is characterized by tinnitus, sweating, headache, and dizziness. Tinnitus is an indication that the maximum acceptable dose has been achieved. Toxicity occurs at a salicylate level of 400 mcg/mL or higher. ASA should be withheld until the symptoms subside and then should be resumed at a lower dose. Increasing the dose would only increase the risk of toxicity. Signs of renal impairment include oliguria and weight gain, which are not present in this patient. This patient has salicylism, not salicylate toxicity, so respiratory support measures are not indicated.
Answer to Question 2
ANS: B
Because cyclooxygenase-2 (COX-2) primarily mediates harmful processes in the body, it is called the bad COX; suppression of COX-2 results in largely beneficial effects. The gastrointestinal (GI) side effects of COX inhibitors are the result of COX-1 inhibition. One of two harmful side effects of COX-2 inhibition is suppression of vasodilation, which leads to an increased risk of myocardial infarction (MI) and stroke. Inhibition of COX-2 causes suppression of inflammation.
