with Complete Solutions 2023 100% Verified 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? - Correct Answer 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? - Correct Answer 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

• Determine what information you have.

D (ordered dose) = 150 mg H (dose on hand) = 75 mg Q (quantity) = 1 tablet

• Plug into the equation and solve

D (150 mg) x 1 tablet = X 1 / 2

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? - Correct Answer HINT There are 1000 mg in one gram.

SAMPLE SOLUTION

• Determine how many milligrams are in 4 grams.
• g x 1000 mg/ 1 g= 4000 mg
• Determine how many 325 mg tablets go into 4000 mg.

4000 mg x1 tablet/ 325 mg = 12.3 tablets

• Round down to the nearest whole tablet = 12 tablets
• 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
