A 110-pound, adult female is admitted to the Emergency Center after receiving burns to 40 percent of her body. Using the Parkland formula, the client's fluid requirements for the first 24 hours after injury is calculated using Lactated Ringer's 4 ml solution x Body weight (in kilograms) x Percent burn. The client should receive one-half of the 24-hour calculated fluid volume in the first 8 hours of treatment. The nurse should set the infusion pump to deliver how many ml/hour during the first 8 hours? (Enter the numerical value only. If rounding is required, round to the nearest whole number.)
