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 A
Explanation
Choice A rationale
The symptoms described by the parent - projectile vomiting followed by hunger - could indicate a serious condition such as pyloric stenosis, which is a narrowing of the opening from the stomach to the small intestine. This condition can lead to severe dehydration and requires immediate medical attention.
Choice B rationale
While burping can help to relieve gas and minor stomach discomfort, it would not address the underlying issue causing the projectile vomiting. This advice might be appropriate for a baby with simple colic or gas, but not for the symptoms described.
Choice C rationale
While oral rehydrating solutions can help to replace lost fluids and electrolytes, they do not address the underlying cause of the projectile vomiting. Furthermore, if the baby is vomiting frequently, they may not be able to keep down the solution.
Choice D rationale
Switching formulas can sometimes help babies who have allergies or intolerances to certain ingredients in their current formula. However, the symptoms described are not typical of a formula intolerance or allergy. Moreover, switching formulas without seeking medical advice can potentially lead to other complications.
Correct Answer is D
Explanation
Choice A rationale
The Haemophilus influenza type b (Hib) vaccine is not contraindicated for people with egg allergies. The Hib vaccine is used to prevent Haemophilus influenza type b, a bacteria responsible for severe pneumonia, meningitis and other invasive diseases almost exclusively in children aged less than 5 years19.
Choice B rationale
The Inactivated poliovirus (IPv) vaccine is not contraindicated for people with egg allergies. The IPV vaccine is used to prevent polio, a crippling and potentially deadly infectious disease19.
Choice C rationale
The Hepatitis B (HepB) vaccine is not contraindicated for people with egg allergies. The HepB vaccine is used to prevent hepatitis B, a viral infection that attacks the liver19.
Choice D rationale
The Influenza vaccine is contraindicated for people with severe egg allergies. Most flu vaccines today are produced using an egg-based manufacturing process and thus contain a small amount of egg protein called ovalbumin19.
