Archie who weighs 44 tb has been given an order for amoxilin 500 mg bid to take before a dentist appointment based on his history of infective endocans. The drug test shows that the daily dose of amoecitin is 50 mg/kg/day in two divided doses. What dose in milligrams is safest for this child?
500 mg
750 mg
250 mg
1000 mg
The Correct Answer is A
To calculate the safest dose of amoxicillin for Archie based on his weight of 44 pounds (lbs) and the recommended dose of 50 mg/kg/day in two divided doses, you should follow these steps:
Step 1: Convert Archie's weight from pounds (lbs) to kilograms (kg).
1 pound = 0.453592 kilograms
44 lbs * 0.453592 kg/lb = 19.504 kg (rounded to the nearest tenth)
Step 2: Calculate the total daily dose based on his weight.
Total daily dose = Weight (kg) * Dose (mg/kg/day)
Total daily dose = 19.504 kg * 50 mg/kg/day = 975.2 mg/day
Step 3: Divide the total daily dose into two equal doses since it's to be administered in two divided doses.
Each dose = Total daily dose / 2
Each dose = 975.2 mg/day / 2 = 487.6 mg/dose
Since it's not possible to administer a fraction of a milligram accurately, you would round the dose to the nearest available dosage strength.
Therefore, the safest dose for Archie would be:
500 mg
So, Archie should take 500 mg of amoxicillin before his dentist appointment.

Correct Answer is D
Explanation
Weight loss in a child with acute glomerulonephritis is often due to a reduction in edema (fluid retention and swelling). Acute glomerulonephritis can lead to significant edema, as the kidneys may not effectively filter excess fluid and waste products from the body. During hospitalization and treatment, interventions such as diuretics and improved kidney function may result in the gradual removal of excess fluid, leading to a decrease in edema and overall body weight.
The other options are less likely to be the primary cause of the weight loss:
A. Poor appetite: While acute glomerulonephritis can affect appetite, especially due to nausea or other symptoms, it is not typically the primary reason for significant weight loss over a short period.
B. Restriction to bed rest: While being on bed rest can lead to muscle atrophy and loss of lean body mass over an extended period, it is unlikely to result in an 8-pound weight loss in just 4 days unless there are additional factors at play.
C. Increased potassium intake: Increased potassium intake alone would not be a primary cause of significant weight loss. High potassium levels in the blood (hyperkalemia) can occur in kidney disease, but it is not typically associated with rapid weight loss.
