Complex math: Doris turner| Questions and Answers with complete solution

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 administeredD(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.
