NURS 325|Complex / Doris Turner Med Math Questions complete solutions, Summer 2023. Suppose Mrs. Turner's orders call for 500 mg of azithromycin to be administered intravenously for community-acquired pneumonia. The solution has been diluted to a concentration of 2 mg/ml and needs to be administered over 1 hour. At what rate should the infusion pump be set? - Determine how many milliliters of the concentration will be delivered to administer the ordered dose. 500 mg x1 mL/2 mg= 250 mL Divide the total number of ml needed to deliver the 500 mg by the expected duration of 1 hour. 250 mL/ 1 hr = 250 mL/hr Number: 250 Units / Rate: mL/hr Problem type: Dosage calculation + Stock on hand Medication: venlafaxine Mrs. Turner's daily medications include venlafaxine extended-release, 150 mg, by mouth, once a day. However, the hospital pharmacy only carries 75 mg extended-release tablets. How many tablets of venlafaxine extended-release should be administered to her? - You can use the equation below, where X is the number of tablets that should be administered D(ordered dose)/H(dose on hand) x Quantity = X SAMPLE SOLUTION 1. Determine what information you have. D (ordered dose) = 150 mg H (dose on hand) = 75 mg Q (quantity) = 1 tablet 2. Plug into the equation and solve D (150 mg) x 1 tablet = X H (75 mg) X = 2 tablets ANSWER Number: 2 Units: tablets Problem tvpe: Total daily dosage Medication: Acetaminophen @ hospital - hypothetical Suppose Mrs. Tumer's provider updated her order for 325 mg, 2 tabs, by mouth q6h PRN temp. 100.5 F to 325 mg, 2 tabs, by mouth q4h PRN temp. 100 5 F. The Davis's Drug Guide reports that acetaminophen has a maximum recommended dosage of 4 g/day How many doses can Mrs. Turner take without exceeding the recommended maximum dosage? - HINT There are 1000 mg in one gram. SAMPLE SOLUTION 1. Determine how many milligrams are in 4 grams. 4 g x 1000 mg/ 1 g= 4000 mg 2. Determine how many 325 mg tablets go into 4000 mg. 4000 mg x1 tablet/ 325 mg = 12.3 tablets 3. Round down to the nearest whole tablet = 12 tablets 4. Divide the total number of tablets by the number tablets in a dose. 12 tablets total x 1 dose/ 2 tablets = 6 doses ANSWER Number 6 Units: doses Problem type: Total daily dose calculation Medication: acetaminophen @ hospital PROBLEM Suppose Mrs. Tuner's current
