Final answer:
The correctly written physician's order from the provided options is A. Amoxicillin 500mg p.o. for 10 days, as it includes the required information. The correct answer is option A.
Explanation:
Of the four physicians' orders provided, A. Amoxicillin 500mg p.o. for 10 days is written correctly. This is based on standard prescription practices that should include the medication name, dosage, route of administration (in this case, orally, denoted as p.o.), and duration or frequency of intake.
The order for Amoxicillin clearly states all of these components, making it an appropriately written prescription. When a physician prescribes medication, calculating the dosage is critical. For example, if a doctor prescribes amoxicillin at 30mg/kg for a child weighing 73.5 lbs, the calculation would first involve converting the weight to kilograms (1 kg = 2.2 lbs), resulting in approximately 33.41 kg.
Multiplying this by 30mg/kg gives a total of 1002.3 mg, requiring approximately two 500 mg tablets to achieve this dose.
