A nurse is preparing to administer ampicillin to a school-age child who weighs 55 lb. The provider prescribes 50 mg/kg/day in 4 equal doses. Available is ampicillin oral suspension 125 mg/5 mL. How many mL should the nurse administer with each dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["12.5"]
To calculate the dosage, first convert the child's weight to kilograms (1 kg = 2.2 lbs), so 55 lbs is approximately 25 kg. The total daily dose of ampicillin prescribed is 50 mg/kg/day, which for a 25 kg child is 1250 mg/day (50 mg/kg * 25 kg). This total daily dose should be divided into 4 equal doses, resulting in 312.5 mg per dose (1250 mg/day ÷ 4 doses/day). The concentration of the ampicillin suspension is 125 mg/5 mL, so to find out how many mL per dose, divide the dose in mg by the concentration and multiply by the volume: 312.5 mg per dose ÷ 125 mg/5 mL = 2.5 * 5 mL = 12.5 mL per dose. Therefore, the nurse should administer 12.5 mL per dose.

Correct Answer is {"dropdown-group-1":"B","dropdown-group-2":"B"}
Explanation
Hyperglycemia: The client's blood glucose levels are elevated, as indicated by the notation of hyperglycemia on Day 3. The symptoms of lethargy, thirst, and frequent urination further support the presence of hyperglycemia, which is often associated with parenteral nutrition due to its high glucose content.
Dehydration: The symptoms of lethargy and frequent urination can also indicate dehydration. The client’s thirst suggests a compensatory mechanism in response to potential fluid loss or insufficient fluid intake. Since parenteral nutrition can sometimes lead to imbalances if not monitored closely, dehydration is a possible concern in this scenario.
