Anesthesiology Report Local anesthesia was administered to the patient at 1:58 prior to surgery. The concentration of the drug in the bloodstream (in mg/L) is modeled by the 8t function where t is minutes since receiving the drug: C(t) = 0.3t2 +4.1 Note: When the concentration drops below 0.1 mg/L, the patient may become conscious. They will need the additional anesthesia administered one half hour prior to reaching this level. The surgery is expected to last 6 hours. Based on this information, when would I need to administer more anesthesia? 5:48 5:54 6:02 a = a = 548 m = 602 i= 554​
