(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.5"]
The nurse needs to administer 50 mg of amitriptyline and each tablet contains 100 mg.
Step 1 is: Calculate the number of tablets by dividing the required dose by the dose available per tablet.
So, 50 mg (required dose) ÷ 100 mg/tablet (dose per tablet)
Step 2 is: Perform the division.
This gives us 0.5 tablets.
Step 3 is: Round the answer to the nearest tenth as instructed.
So, 0.5 rounded to the nearest tenth is 0.5.

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.
