Question

1. the medical assistant is planning to schedule appointments for a special clinic. appointments will be 15 minutes each for an eight - hour day, with a half hour allotted for lunch during which there will be no appointments scheduled. how many appointments can the medical assistant schedule?
2. bellas temperature was 101.6 degrees f using a temporal scanner. her mother gives her an antipyretic drug and measures it again in one hour. it read 99.0 degrees fahrenheit. how many degrees lower is her temperature at this time?
3. the drug order reads to give 7.5 mg by injection. the drug is packaged 10 mg/6ml. how many ml of the drug will be injected?
4. a patient has iv fluids running at 100 ml per hour for 8 hours, and then it will be decreased to 75 ml per hour for 8 hours and then further decreased to 50 ml per hour for 8 hours. how many ml will the patient receive in 24 hours? how many ounces will she receive in 24 hours?

Explanation:

Step1: Calculate available time

An 8 - hour day has 8×60 = 480 minutes. Subtract 30 - minute lunch break. Available time is 480−30 = 450 minutes.

Step2: Calculate number of appointments

Each appointment is 15 minutes. Number of appointments = $\frac{450}{15}=30$.

Step1: Find temperature difference

Initial temperature is 101.6°F and final is 99.0°F. Difference = 101.6−99.0 = 2.6°F.

Step1: Set up proportion

Let $x$ be the volume of drug to be injected. We have the proportion $\frac{7.5}{x}=\frac{10}{6}$.

Step2: Cross - multiply and solve

Cross - multiplying gives 10$x$ = 7.5×6. So 10$x$ = 45, and $x=\frac{45}{10}=4.5$ mL.

Step1: Calculate fluid amount for each stage

For the first 8 hours at 100 mL per hour, amount is 100×8 = 800 mL. For the next 8 hours at 75 mL per hour, amount is 75×8 = 600 mL. For the last 8 hours at 50 mL per hour, amount is 50×8 = 400 mL.

Step2: Calculate total mL

Total mL = 800 + 600+400 = 1800 mL.

Step3: Convert mL to ounces

1 fluid ounce is approximately 29.5735 mL. So number of ounces = $\frac{1800}{29.5735}\approx60.87$ ounces.
