Question 3 of 5
The physician prescribes penicillin potassium oral suspension 56 mg/kg/day in four divided doses for a client with anorexia nervosa who weighs 25 kg. The medication dispensed by the pharmacy contains a dosage strength of 125 mg/5 ml. How many milliliters of solution should the nurse administer with each dose?
Correct Answer: A
Rationale:
To determine the total daily dosage, set up the following proportion: 25 kg/X = 1 kg/56 mg, X = 1,400 mg. Next, divide the daily dosage by four doses to determine the dose to administer every 6 hours: X = 1,400 mg/4 doses, X = 350 mg/dose. The adolescent should receive 350 mg every 6 hours. Lastly, calculate the volume to give for each dose by setting up this proportion: X/350 mg = 5 ml/125 mg, X = 14 ml.

Correct Answer: A
Rationale: This child is in Erikson's developmental stage of initiative versus guilt. Guilt develops when the child is made to feel bad about his behavior. Ignoring the negative behavior shows the child that he'll gain nothing through negative behavior such as temper tantrums. Promising the child a new toy or giving in to his demands will reinforce his negative behavior by rewarding his tantrums. Mimicking the child will make him feel guilty.
