At 0800, Mr. Larson reports a moderate pain level of 5, and so you administer oxycodone 5 mg/
acetaminophen 325 mg, 1 tablet, by mouth. At 1200, Mr. Larson reports mild pain rated 3, so
you administer acetaminophen 325 mg, 2 tablets, by mouth. At this point, how much
acetaminophen has Mr. Larson taken? Dose 1 = 325 mg acetaminophen x 1 tablet = 325 mg
acetaminophen
Dose 2 = 325 mg acetaminophen 2 tablets = 650 mg acetaminophen;
325 mg + 650 mg
= 975 mg acetaminophen
In Mr. Larson's orders, the enoxaparin is prescribed for prophylaxis of DVT following knee
replacement surgery, and he is ordered 30 mg by subcutaneous injection every 12 hours.
Suppose the pharmacy stocks multi-use vials of 300 mg/ 2 mL enoxaparin. How much will you
need to draw up to administer a 30 mg dose? Ordered dose = 30 mg
Dose on hand = 300 mg/ 2 mL
30 mg x (3 mL enoxaparin/ 300 mg)
= 0.3 mL enoxaparin
For patients with unstable angina, a potential treatment is enoxaparin administered by
subcutaneous injection 1 mg/ kg every 12 hours. Suppose Mr. Larson were being treated for
unstable angina.
, a. If Mr. Larson weighs 227 lbs, how much enoxaparin should be administered? (Round your
answer to the nearest whole number)
b. If Mr. Larson weighed 180 lbs, how much enoxaparin should be administered? (Round your
answer to the nearest whole number) a. 227 lbs x (1 kg/ 2.2 lbs) x (1 mg/ 1 kg)
= 103.18 → 103 mg enoxaparin
b. 180 lbs x (1 kg/ 2.2 lbs) x (1 mg/ 1 kg)
= 81.81 → 82 mg enoxaparin
For patients with deep vein thrombosis or pulmonary embolism, a potential treatment is
enoxaparin administered 1.5 mg/ kg once daily by subcutaneous injection. Suppose Mr. Larson
were being breasted for a pulmonary embolism and weighed 227 lbs. How much enoxaparin
should he be administered each day? (Round your answer to the nearest whole number)
227 lbs x (1 kg/ 2.2 lbs) x (1.5 mg/ 1 kg)
= 154.7 → 155 mg enoxaparin
For moderate pain, Mr. Larsen is able to take oxycodone 5 mg/ acetaminophen 325 mg, 1
tablet, every 4 hours. Suppose he takes all available doses in 24 hours. How many mg of
oxycodone will he have ingested? (24 hours/ 4 hours) = 6 doses
5 mg x 6 doses
= 30 mg oxycodone
