A 4-year-old child who weighs 44 lbs is diagnosed with Streptococcal Pharyngitis and is prescribed Penicillin. 40 mg/kg/day, twice a day for 10 days. The suspension is written as 400 mg/5 ml. Calculate one dose in mg.
400 mg.
800 mg.
1200 mg.
1600 mg.
The Correct Answer is B
Choice A rationale:
The dosage prescribed for the child is 40 mg/kg/day, twice a day for 10 days. The child weighs 44 lbs, which is approximately 20 kg (1 lb = 0.45 kg). Therefore, the total daily dosage would be 40 mg/kg * 20 kg = 800 mg. This is split into two doses, so each dose would be 400 mg, not 400 mg per 5 ml as in the suspension.
Choice B rationale:
As explained above, the total daily dosage is 800 mg, split into two doses of 400 mg each. The suspension is written as 400 mg/5 ml, so one dose would be 400 mg.
Choice C rationale:
This choice is incorrect because it does not accurately calculate the dosage based on the child's weight and the prescribed dosage regimen.
Choice D rationale:
This choice is incorrect because it suggests a higher dose than what is prescribed. The correct dosage, based on the child's weight and prescription, is 800 mg per day, split into two doses of 400 mg each.

Correct Answer is A
Explanation
Choice A rationale:
The symptoms described by the baby's father, including confusion and having conversations with herself, are concerning and could indicate a severe mental health issue or a neurological problem. Urgent evaluation in an emergency room is necessary to rule out any acute medical or psychiatric condition that could be causing these symptoms. This is crucial for ensuring the safety and well-being of both the mother and the newborn.
Choice B rationale:
Bringing the wife to the office for medication is not appropriate in this situation without a proper evaluation. The symptoms described are severe and require immediate attention in an emergency room setting, where comprehensive assessments can be conducted.
Choice C rationale:
Outpatient care is not suitable for the described symptoms. The mother's confusion and hallucinations suggest a severe condition that requires urgent evaluation in a controlled environment like an emergency room.
