Interpreting a Medical Prescription

Maria is a 65-year-old woman who was prescribed medication after a hospital visit. The doctor's note says: 'Take 2 tablets of Drug A every 8 hours for 7 days. Take 1 tablet of Drug B once daily for 10 days. Take 3 tablets of Drug C every 6 hours as needed for pain, not to exceed 12 tablets in 24 hours.' Maria lives alone and sometimes forgets her schedule. She has a pill organizer with sections for morning, noon, evening, and night. She wants to know how many tablets of each drug she needs to buy and how to organize them to avoid confusion. She also worries about taking too much of Drug C.

1. Calculate the total number of tablets Maria needs to buy for each drug for the entire course.

Read the worked answer

Drug A: 2 tablets every 8 hours = 3 times per day (since 24/8=3). So 2×3=6 tablets per day. For 7 days: 6×7=42 tablets. Drug B: 1 tablet daily for 10 days: 1×10=10 tablets. Drug C: 3 tablets every 6 hours as needed, max 12 tablets per 24 hours. Since it's 'as needed', we cannot calculate exact total. But to be safe, she should buy enough for the maximum: 12 tablets/day × 10 days (if needed for 10 days) = 120 tablets. However, the prescription doesn't specify duration for Drug C, so she should ask the doctor. For planning, she might buy a smaller amount and refill as needed. But the question asks for total needed for the entire course; for Drug C, it's not fixed. So we can only say: Drug A: 42 tablets, Drug B: 10 tablets, Drug C: variable, up to 12 per day, duration unspecified.

2. How should Maria organize her pill organizer to accommodate the schedule for Drug A and Drug B? Consider the timing of doses and the sections available.

Read the worked answer

Drug A is taken every 8 hours, so doses are at e.g., 6 AM, 2 PM, 10 PM. These times can be assigned to morning, afternoon, and night sections. Drug B is once daily, so she can take it at a consistent time, e.g., morning. The pill organizer has sections: morning, noon, evening, night. She can put Drug A in morning (6 AM), evening (2 PM), and night (10 PM). Drug B in morning. Noon section may be unused for these drugs, but could be used for Drug C if needed. She should set alarms or use a chart to remember.

3. What should Maria do to ensure she does not exceed the maximum daily dose of Drug C? Suggest a practical strategy.

Read the worked answer

Maria should track her Drug C intake carefully. She can use a pill counter or a chart to record each dose. Since the max is 12 tablets in 24 hours, and each dose is 3 tablets, she can take at most 4 doses per day (4×3=12). She should space doses at least 6 hours apart. She could set a timer or use a medication app. She should also inform her doctor if she needs it frequently, as it may indicate a problem. She should keep a written log with times and number of tablets taken.
