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","B","C"]
Explanation
Choice A rationale:
Dried beans are excellent sources of plant-based protein and are suitable for a vegetarian diet. They are also rich in fiber, vitamins, and minerals.
Choice B rationale:
Seeds, such as chia seeds, flaxseeds, and pumpkin seeds, are good sources of protein, healthy fats, and various nutrients. They are suitable for vegetarians and can be incorporated into meals, salads, or smoothies.
Choice C rationale:
Peanut butter, made from ground peanuts, is a protein-rich food suitable for vegetarians. It can be spread on bread, added to smoothies, or used in various recipes.
Choice D rationale:
Bagels are not typically high in protein. They are primarily carbohydrate-based and do not serve as a significant source of protein for individuals following a vegetarian diet.
Choice E rationale:
Eggs are a good source of high-quality protein; however, they are not suitable for a strict vegetarian diet. Some vegetarians, known as ovo-vegetarians, include eggs in their diet, but strict vegetarians, known as vegans, avoid all animal products, including eggs.
Correct Answer is D
Explanation
Choice A rationale:
Bronchoscopy is not the essential test for diagnosing cystic fibrosis. Bronchoscopy is a procedure that allows the healthcare provider to visualize the airways and lungs but is not the primary test for cystic fibrosis diagnosis. Cystic fibrosis is primarily diagnosed through genetic testing and sweat chloride testing.
Choice B rationale:
Serum calcium levels are not specific to cystic fibrosis diagnosis. Serum calcium levels are typically used to assess calcium balance in the body and are not directly related to cystic fibrosis diagnosis.
Choice C rationale:
Urine creatinine levels are not specific to cystic fibrosis diagnosis. Urine creatinine levels are often used to assess kidney function and muscle breakdown but are not diagnostic for cystic fibrosis.
Choice D rationale:
Sweat chloride test is essential in establishing the diagnosis of cystic fibrosis. Cystic fibrosis is characterized by the abnormal transport of chloride across cell membranes, leading to salty sweat. The sweat chloride test measures the amount of chloride in the sweat and is a key diagnostic test for cystic fibrosis. Values above a certain threshold (typically 60 mmol/L) are suggestive of cystic fibrosis.
