Explanation
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.
