The physician orders Ancef 400mg IV every 8 hours for a child weighing 44 lbs. You have on hand Ancef 330 mg/mL. The recommended daily IV dosage for a child is 75 mg/kg/day.
What is the safe and single dose for this child?
The Correct Answer is ["500"]
What is the safe and single dose for this child?
The recommended daily dosage is 75 mg/kg/day. For a 20 kg child:
Safe daily dose= 75 mg/kg/day × 20 kg
= 1500 mg/day
Since the child is receiving the medication every 8 hours, the single dose would be:
Single dose = 1500 mg ÷ 3

Correct Answer is A
Explanation
a) Discontinue the feedings and notify the physician of your assessment findings: These are signs of feeding intolerance or possible complications such as delayed gastric emptying, infection, or dumping syndrome. Stopping the feeding prevents further distress, and the physician should be informed promptly.
b) Continue feedings as ordered: Continuing feedings may worsen the symptoms and put the patient at risk for aspiration or further gastrointestinal complications.
c) Administer prn pain medication: Pain medication will not address the underlying issue of nausea, vomiting, and GI symptoms. It may also mask symptoms or cause further GI upset.
d) This is a normal response, continue feedings as ordered: These symptoms are not normal. Nausea, vomiting, distention, and frequent diarrhea suggest a problem with the feeding regimen.
