Correct Answer is ["2"]
Explanation
Step 1: The total daily dose to be administered is300 mg of trazodone.
Step 2: The total daily dose is divided equally every 8 hours, so each dose is one third of the total daily dose. So, 300 mg ÷ 3 =100 mg per dose.
Step 3: The available trazodone tablets have a concentration of50 mg/tablet. This means that for every 1 tablet, there are 50 mg of trazodone.
Step 4: To find out how many tablets should be administered per dose, we divide the dose by the concentration. So, 100 mg ÷ 50 mg/tablet =2 tablets.
The nurse should administer 2 tablets of trazodone in each dose.
Correct Answer is ["2.8"]
Explanation
Step 1: The dose to be administered is9 mg of aripiprazole.
Step 2: The available aripiprazole injection has a concentration of9.75 mg/3 mL. This means that for every 3 mL of the solution, there are 9.75 mg of aripiprazole.
Step 3: To find out how many mL should be administered, we divide the dose by the concentration. So, 9 mg ÷ (9.75 mg/3 mL) = 2.769230769230769 mL.
Step 4: Round the answer to the nearest tenth. So, 2.769230769230769 mL rounds to2.8 mL.
