A patient who takes aspirin for rheumatoid arthritis is admitted to the hospital complaining of headache and ringing in the ears. The plasma salicylate level is 300 mcg/mL, and the urine pH is 6.0. What will the nurse do?

Question

a. Increase the aspirin dose to treat the patient's headache.
b. Notify the provider of possible renal toxicity.
c. Prepare to provide respiratory support, because the patient shows signs of overdose.
d. Withhold the aspirin until the patient's symptoms have subsided.

Answer 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.
