A child weighs 6 lbs and is to receive Ampicillin 50 mg/kg/24 hrs and then it’s divided into q hr doses.
How many mg will he receive with each dose?
90 mg
60 mg
36 mg
290 mg .
The Correct Answer is C
The correct answer is Choice C.
Step 1: Convert the child’s weight from lbs to kg.
Since 1 lb is approximately 0.45 kg, a child who weighs 6 lbs weighs approximately 2.72 kg (6 lbs × 0.45 =2.72 kg). Step 2: Calculate the total daily dose of Ampicillin. The total daily dose is 50 mg/kg/day, so for a child who weighs 2.72 kg, the total daily dose would be approximately 136 mg (50 mg/kg/day × 2.72 kg = 136 mg/day). Step 3: Since the total daily dose is divided into q hr doses (4 doses per day), each dose would be approximately 34 mg (136 mg/day ÷ 4 doses/day = 34 mg/dose). So, the child will receive approximately 34 mg of Ampicillin with each dose.

Correct Answer is B
Explanation
Choice A rationale
Hypotension, or low blood pressure, is not typically associated with nephrotic syndrome. In fact, some patients with nephrotic syndrome may experience high blood pressure.
Choice B rationale
Generalized edema, or swelling, is a common characteristic of nephrotic syndrome. It occurs due to the loss of proteins in the urine, which leads to a decrease in the amount of protein in the blood. This decrease in blood protein levels causes fluid to move from the blood vessels into the tissues, leading to swelling.
Choice C rationale
Increased urinary output is not typically associated with nephrotic syndrome. In fact, some patients may experience decreased urine output.
Choice D rationale
Bright red blood in the urine is not a typical symptom of nephrotic syndrome. Hematuria, or blood in the urine, when present in nephrotic syndrome, is usually microscopic and not visible to the naked eye.
Correct Answer is B
Explanation
Choice A rationale
It is not advisable for a parent to attempt to reinsert the tubes if they fall out. This could potentially cause harm to the child’s ear.
Choice B rationale
If the tubes fall out, the parent should call the healthcare clinic to report this. The healthcare provider can then decide on the appropriate next steps.
Choice C rationale
It is not accurate to reassure the mother that the tubes will not fall out. Tympanostomy tubes are designed to fall out on their own after a certain period of time.
Choice D rationale
Taking the child to an emergency department is not necessary unless there are signs of infection or other complications.
